    • sur Ecodiv.earth: An addon to download the AHN data in GRASS GIS

      Publié: 23 March 2024, 12:00am CET
      The r.in.ahn addon

      In the previous post, I introduced the ‘Actueel Hoogtebestand Nederland’. To start with a small correction, the version 4 I mentioned isn’t the latest version. Version 5 is being rolled out and is already available for the northern part of the country. But for now, let’s focus on version 4.

      In the previous post, I presented some steps to download the AHN for a specific area and import it in GRASS GIS. Downloading was easy using the r.in.wcs addon. However, a few extra steps were required to ensure the imported data would align with the extent and resolution of the original AHN data.

      Easy, but why not make it easier yet? So, as it was a rainy day anyway, I used the code presented earlier and wrapped it up in the addon r.in.ahn. Let’s see how to download the DTM for the Land van Cuijk again, but this time using the new addon.

      ©


      Download the DTM for a selected area

      Note that this addon only works in locations with the coordinate reference system RD New (EPSG 28992). This is that the CRS of the original data, and the addon is meant to ensure you download the data as it is. This is akin to how the r.in.gdal import function works. If you want to import and reproject the data on the fly (similar to the r.import function), you can use the r.in.wcs addon.

      This example shows the steps to download the 0.5-meter resolution DTM for the Land van Cuijk. You’ll need to install the r.in.wcs and r.in.ahn addons 1 2.

      Install the required addons.

      First step is to import the Python libraries. Note, this will not be repeated with the next scripts.

      import grass.script as gs

      Now, you can install the two addons using the g.extension function.

      gs.run_command("g.extension", extension="r.in.wcs")
gs.run_command("g.extension", extension="r.in.ahn")

      Install the two addons using the g.extension function.

      g.extension extension=r.in.wcs
g.extension extension=r.in.ahn

      You need the g.extension function to install addons. In the main menu, go to Settings > Addons extension > Install extension from addon. Alternatively, type in g.extension on the command line. The example below is for r.in.wcs. Repeat this step for r.in.ahn.

      Figure 1: The g.extension function, started from the command line. Figure 1: The g.extension function, started from the command line.

      Now, download the administrative boundaries of the Dutch municipalities, and extract the boundaries of the “Land van Cuijk”.

      Download layer with administrative boundaries of the neighborhood.

      gs.run_command(
    "v.in.wfs",
    url="https://service.pdok.nl/cbs/wijkenbuurten/2022/wfs/v1_0?",
    output="municipalities",
    name="gemeenten",
)

      Next, extract the boundaries of the municipality of “Land van Cuijk”

      gs.run_command(
    "v.extract",
    input="municipalities",
    where="naam = 'Land van Cuijk'",
    output="LandvanCuijk",
)

      Get the vector layer with the boundaries of the municipality.

      v.in.wfs url="https://service.pdok.nl/cbs/wijkenbuurten/2022/wfs/v1_0?" \
    output=municipalities name=gemeenten

      Next, extract the boundaries of the municipality of “Land van Cuijk”

      v.extract input=municipalities where="naam = 'Land van Cuijk'" \
    output="LandvanCuijk"

      Type in v.in.wfs on the command line or in the console. You can also find the function under main menu > File > Import vector data. This opens the following screen (you need to fill in parameters in two tabs):

      Figure 2: Download the vector layer with the municipality boundaries. Define the base URL and the name of the output layer. Figure 2: Download the vector layer with the municipality boundaries. Define the base URL and the name of the output layer. Figure 3: Download the vector layer with the municipality boundaries. Fill in the name of the WFS layer to download. Figure 3: Download the vector layer with the municipality boundaries. Fill in the name of the WFS layer to download. Figure 4: Extract the boundaries of the municipality of Land van Cuijk. Select the name of the vector layer with municipalities and give the name of the output layer. Figure 4: Extract the boundaries of the municipality of Land van Cuijk. Select the name of the vector layer with municipalities and give the name of the output layer. Figure 5: Extract the boundaries of the municipality of Land van Cuijk. Fill in the query, which defines which features you want to select and save. Tip: Use the convenient query builder. Figure 5: Extract the boundaries of the municipality of Land van Cuijk. Fill in the query, which defines which features you want to select and save. Tip: Use the convenient query builder.

      Now, set the region to match the extent of the municipality. Note, you do not need to be concerned with the resolution; r.in.ahn will adjust the resolution and extent to make sure the imported data aligns perfectly with the original AHN data. This is done by setting the resolution to 0.5 meters and subsequently extending the region’s extent until it aligns with the original AHN data layer.

      Set the region to match the vector layer LandvanCuijk.

      gs.run_command("g.region", vector="LandvanCuijk")

      Get the vector layer with the boundaries of the municipality.

      g.region vector=LandvanCuijk

      Type in g.region on the command line or console, or open the function’s window via menu | Settings | Computational region | Set region.

      Figure 6: Set the region to match the extent of the vector layer LandvanCuijk. Figure 6: Set the region to match the extent of the vector layer LandvanCuijk.

      Now, you can run the r.in.ahn function to import the layer. Note that by default, the addon will change the region you just defined. It will set the resolution to 0.5 meters (this is the resolution of the AHN data you are about to download). It will furthermore expand the extent so that it aligns perfectly with the AHN data.

      Import the DTM using the r.in.ahn function.

      gs.run_command("r.in.ahn", product="dtm", output="dtm_05")

      Get the vector layer with the boundaries of the municipality.

      r.in.ahn product=dtm output=dtm_05

      Type in r.in.ahn on the command line or console. A third way is shown in the image below. Open the Tools tab and go to Addons. The function should be available there.

      Figure 7: Open the r.in.ahn plugin, select the product to download (dtm or dsm) and provide the output layer name. Figure 7: Open the r.in.ahn plugin, select the product to download (dtm or dsm) and provide the output layer name. Download whole tiles

      If you set the -t flag, the function will import the DTM or DSM for all 6.5×5 km AHN tiles that overlap with the current region. In addition, a vector polygon layer will be created with the tile boundaries.

      Define the region for which you want to download the data, and import the DSM using the r.in.ahn function. Set the -t flag to download the DTM for the area covered by the tiles that overlap with the region.

      # Set the region
gs.run_command("g.region", n=412572, s=411280, w=188911, e=190085)

# Import the tile(s) that include the selected region 
gs.run_command("r.in.ahn", product="dtm", flags="t",
                output="dtm_05_subset")
      # Set the region
g.region n=412572 s=411280 w=188911 e=190085)

# Import the tile(s) that include the selected region 
r.in.ahn -t product=dtm output=dtm_05_subset)

      Open the g.region addon by typing g.region on the command line, in the console, or using the menu. Fill in the northern, southern, western, and eastern limits of the area for which you want to download the data.

      Figure 8: Set the region bounds. Figure 8: Set the region bounds.

      Type in r.in.ahn on the command line or console. Or go to the Tools tab and go to Addons. The function should be available there. Fill in the required fields, like in the previous examples. Next, go to the Optional tab and select Download whole tiles.

      Figure 9: Open the r.in.ahn plugin, select the product to download (DTM or DSM) and provide the output layer name. Figure 9: Open the r.in.ahn plugin, select the product to download (DTM or DSM) and provide the output layer name.

      The extent of the imported layer covers the 6.5×5 km AHN tile. In addition to the raster layer, you’ll have a vector layer with the boundary of the downloaded tile(s). This vector layer has the same name but with the suffix *_tiles*.

      You should be aware that running the function will adjust the computational region so that it aligns with the imported data. You can avoid this by setting the -g flag, as illustrated in Figure 10.

      Figure 10: A: The downloaded 6.5 x 5 km AHN tiles that intersect with the user-defined region, here indicated by the orange outline. In addition, a vector layer with the boundaries of the tiles is created. The red outline shows the adjusted region extent after running the function. The blue outlines show the boundaries of the downloaded tiles. B: The same, but with the -g flag set. With this flag set, the user-defined region (red outline) will not be altered .

      1. You are expected to be familiar with GRASS GIS and the concept of region used in GRASS GIS. If you are new to GRASS GIS, you are warmly recommended to first check out the GRASS GIS Quickstart and the explanation about the GRASS GIS database.??

      2. Downloading the DTM for the whole municipality will take a while. If you want to speed things up, you can work with a smaller area by using your own vector data.??

    • sur Jackie Ng: Avalonia UI Test Drive

      Publié: 22 March 2024, 9:40am CET

      As the title implies, this blog post is about my experience test driving Avalonia UI.

      So why am I doing this?

      I've been getting growing questions lately about whether MapGuide Maestro works on Linux via Mono. 

      Sadly I no longer emphasize anything regarding Mono compatibility because.

      • WinForms support (in legacy .net Framework 4.x) on Mono is pretty much a hack.
      • And since we've moved away from legacy .net Framework to .net 6.0, the combination of WinForms + .net 6.0 is probably an unsupported combination (you don't use Mono to run .net core/5.0+ applications, you use Microsoft's official SDK/runtime). I'm also not too keen to waste time and resources to test and find out.
      The best and practical approach for a multi-platform MapGuide Maestro would be to at a minimum to rewrite the UI in a library/framework where support on non-Windows platforms is a first-class citizen.

      And in terms of .net multi-platform UI frameworks, there's only one logical choice: Avalonia UI

      While it is not in my immediate plans to rewrite MapGuide Maestro's UI in Avalonia, I wanted to at least explore the feasibility of building such a UI even if all the actual functionality is mocked up, just to see how easy or difficult the whole process is.

      Hence the motivation for this post.

      So why Avalonia?

      Avalonia is effectively the "spiritual successor" to WPF, and adopts most of the same patterns and practices when building UIs for Avalonia.

      I had first heard about Avalonia when it was formerly known as Perspex and at the time, from the screenshots of example Perspex applications on Windows and non-Windows platforms, it was clear at that point in time the range of possible applications one can build with Perspex was quite limited and building an application like Maestro on top of Perspex was not feasible.

      Just recently, I had heard about the framework now known as Avalonia again and this time round there was a lot more positive buzz around it, so I gave it another look and was much more impressed at its capabilities and richer suite of UI controls to build applications with.

      Our objective 

      My objective with this Avalonia learning exercise was to build a minimal multi-document interface skeleton application, mimicking the primary functionality (UI-wise) of MapGuide Maestro.

      • Being able to present a login UI to connect to a MapGuide Server
      • Present MapGuide Server resources in a tree view
      • Open resources in a region of tabbed editor panels and being able to close them.
      This is a crude wireframe of the kind of UI I wanted to build.
      If this kind of UI looks familiar, yes it's basically the UI for tools like:MapGuide Maestro is an IDE-like application (in terms of UI), so my first instinct is to look for a Visual Studio like docking library for Avalonia. However, I've been using Visual Studio Code more often than full Visual Studio as my daily driver for coding and the VSCode UI has become my default UI that I want to replicate for any IDE-like application with a multi-document interface.
      The benefit of such a UI, is that it doesn't require an explicit VS-style window docking control like I have for the current WinForms-based MapGuide Maestro. I can already see the controls needed to build such a UI
      Any UI toolkit worth its salt should to able to provide these basic controls.
      This is a proof-of-concept, so we won't be using the existing Maestro API to talk to actual MapGuide Servers. Instead such functionality will be mocked up for this application. The main purpose of this exercise is to see if Avalonia provides enough of the base UI elements to build a hypothetical version of MapGuide Maestro on top of.
      It turns out this exercise was fraught with several challengesChallenge #1: Getting familiar with Avalonia conceptsThe first challenge was simply getting familiar with Avalonia concepts. Being someone who did .net desktop app development primarily in Windows Forms, I skipped over WPF, and its XAML-based variants/successors like Silverlight, Xamarin Forms, UWP, and MAUI, and Avalonia being a "spiritual successor" to WPF meant that I didn't have a potential conceptual head start on Avalonia that one might have if they already had experience with WPF and its XAML-based derivatives.
      However, I was familiar with the MVVM pattern and data-binding, which is used heavily in Avalonia. I already had experience in knockout.js building/maintaining some of our web apps in my day job, and these concepts learned from knockout.js mostly translate cleanly 1:1 to Avalonia.
      The other Avalonia concepts I'll have to figure out as we go along.
      Challenge #2: WebAssembly (WASM) supportBefore I begin, I must take the MapGuide-knowledgable readers of this post back in time, way back to when MapGuide Open Source 1.0 was released.
      Do you remember how this new (at the time), re-invented version of MapGuide was released, but the only authoring option at the time was to buy a license of Autodesk MapGuide Studio? Not a pretty look if you are offering a free and open source web map GIS server, but the authoring tools are not?
      Some members of the MapGuide community were aware of this glaring discrepancy and created a web-based equivalent of MapGuide Studio called Web Studio built fully with HTML/JS/CSS. Unfortunately, Web Studio was really bare-bones in terms of authoring capabilities and the code being written in the pre-historic era of javascript (this was circa 2006-2007) which did not make it conductive to external contribution. React, TypeScript and friends weren't around then, so trying to enhance Web Studio with new features was extremely challenging. I once tried to add at least a generic XML text editor fallback for Web Studio so you had something to edit various resources where Web Studio did not provide a dedicated editor UI for, but alas this was just too challenging for me and I gave up on such an idea.
      But eventually another user of the MapGuide community solved this problem more directly by developing and releasing a v1.0 of a windows .net desktop application that you all know as MapGuide Maestro. As an aside, I am not the original author of MapGuide Maestro in case you're wondering, I merely took over development and maintenance of Maestro from the 2.1 release onwards.
      Anyways, back to the topic at hand, when I created the new Avalonia application with the provided project template, I was most surprised to see that the generated solution came with a project that compiled to WebAssembly (WASM) that was ready to run in your web browser!
      This was a mind-blowing revelation for me from a conceptual standpoint. It means our hypothetical MapGuide Maestro built on Avalonia could not only exist as a regular desktop application, but the WASM build of this application could be dropped in the the wwwroot of a MapGuide Web tier installation and you would now have a modern version of Web Studio, but much more powerful and capable, because it is just MapGuide Maestro ... now in your web browser!
      Since our starter project template includes a functioning WASM browser target. I now had a strong incentive to keep this target active and working, because the prospect of being able to run MapGuide Maestro in a web browser is a very tempting proposition. Therefore, the choice of libraries and APIs I use is constrained by my new requirement of being able to work in a browser/WASM environment.
      For example, I originally wanted to use MVVMDialogs to simplify working with dialogs (Maestro has lots of dialogs, so I figure such a library could be useful), but I couldn't get this library to work in a WASM environment with some of my testing dialogs, so this was a no-go. Since this was just a proof-of-concept, there wasn't a need to have working dialog system, but it does mean if this were to go beyond a proof-of-concept and into an actual application where we will inevitably have to present a dialog of some sort, I'd have to come with a paradigm that can work in both desktop and browsers.
      Another problem with this WASM target is that I can't seem to debug it in Visual Studio. You can launch the WASM target in the debugger and spawn a new browser window to launch your app, but any breakpoints you stick in your C# code are not being hit. I'm not sure if this a shortcoming or a broken feature, but it is somewhat concerning if we were to go full steam ahead with support WASM as a compilation/deployment target.Challenge #3: "Large scale" MVVMAlthough I already knew the MVVM pattern from knockout.js, my scope of usage was mostly limited to using knockout.js to building "islands" of interactive client-side content on primarily server-generated web pages. So I didn't really have an idea of how to apply such a pattern on a full blown Single Page Application (SPA), which is pretty much what we're trying to achieve (conceptually) in Avalonia. By the time I was building SPAs proper, I had moved on the popular stuff like React, which is how I gained the knowledge needed to build a modern replacement map viewer for MapGuide and my usage of knockout.js fell by the wayside as a result, so I never figured out the answer for how to do large scale MVVM.
      The main problem was that in a large scale MVVM, how do view models communicate with each other without a tight parent-child coupling?
      I deduced that for starters, we definitely need to use dependency injection. Various view models will need to access different services and if we had a root view model with explicit nested child view models (each with their own service requirements), it would be an absolute pain to have to setup these various view models. Using a DI container means we can offload this concern to it and we can focus on just asking the DI container for a particular view model and it will setup all the required services for it for us provided we register everything properly with the DI container.
      For better WASM support, I wanted a dependency injection container that is not driven by reflection to make the code more friendlier to app trimming. We want to be able to app trim on publish so that we can eliminate unused code and reduce the final binary size. This is most desirable for the WASM target as app trimming means smaller binaries, which means smaller payloads to download in a web browser. StrongInject was chosen for this reason as it was a "compile-time" DI container that can verify all your dependencies are registered properly before running the application through the magic of source generators, generating all the necessary registration and validation code for you.

      Finally, to be able to communicate between view models without necessary parent-child coupling, the messenger facility of the MVVM toolkit can be used. With this messenger facility, we simply:
      • Have select view models be recipients of certain messages
      • Have our application services (that various view model commands call) send these messages.
      • Relevant recipients get notified and update themselves (and their bound UIs) accordingly as a result.
      I don't know if this is the proper usage of MVVM pattern in a "large scale" application, but it makes sense internally in my mind.Challenge #4: TabControl binding of heterogenous/polymorphic contentOur proof-of-concept app has a main tab region where tabs of various document content are shown. I figured out easily that their TabControl component is supposed to be data-bound to an observable collection of view models, but what really stumped me was how bind this control to an observable collection of polymorphic editor view models?
      The reason is because the tab content we want to show is not homogenous. One open editor tab could be for a layer, one for a map, one for a feature source, etc, etc. So we need to be able to show different tabs on the same tab control. 
      Avalonia documentation is pretty scant on this topic. All examples I found assume homogenous series of tab content, which is not our case.
      Just for laughs, since AI has been hyped for soon taking away everyone's jobs (even us devs), I figured I'd ask huggingface chat (as a guest), how would you solve this problem?

      Unfortunately, the provided code sample does not work out of the box. It clearly assumed Avalonia = WPF and gave me a WPF-based solution. The giveaway was the Avalonia TabControl does not have an ItemTemplateSelector, but the WPF TabControl does.
      But Avalonia sharing many conceptual similarities with WPF meant that although the answer provided wasn't correct, parts of the answer were applicable and did lead me down to further avenues of inquiry and eventually I found the solution: It was to define a data template for every possible derived tab view model class in the same UserControl where the TabControl was specified.Final challenge: Avalonia VS designerThis wasn't so much a challenge, rather an annoyance. The Avalonia designer in Visual Studio has some teething issues
      • Intellisense/autocomplete is somewhat flaky when writing binding expressions and when you're doing a lot of data-binding, having the editor giving you and incomplete or outdated list of properties you can bind to becomes annoying. A full project build generally fixes this, but it is annoying having to do this every time I add new observable properties or commands to an existing view model class.
      • It's also not rename-aware, so observable property or command renames will result in stale binding expressions, causing havoc with the designer and have to be manually fixed up in the XAML. Choose your observable property names wisely I suppose, because renaming them afterwards is painful.
      The end result and overall thoughtsA week later from that post, after addressing and/or navigating around these various challenges, we have a functional skeleton application!




      And if these screenshots don't convince you, thanks to being able to deploy as a WASM target, I deployed a copy to GitHub pages, so you can see this app for yourself right in your WASM-enabled web browser!

      The source code for this app can be found here. One day this may form the basis of a new (true) multi-platform version of MapGuide Maestro, but for now this lies as a potentially useful starting point for building a tabbed-multi-document editor application with Avalonia.
      So what did I think of Avalonia from this little experiment? 
      • I like it mostly. My pre-existing experience on knockout.js helped greatly with picking up MVVM and data-binding. My initial prediction of a VSCode-style UI layout being buildable turned out to be true.
      • I like the default (project template provided) choice of MVVM Toolkit for applying the MVVM pattern. I like their heavy use of source generators to make adding new observable properties and commands to a view model being a simple case of tacking [ObservableProperty] on a field or tacking [RelayCommand] to a private method and having the source generator generate all of the boilerplate code for you (and it's a lot of boilerplate!).
      • The revelation that Avalonia has a WASM deployment target was both exciting and "cramping my style". It meant that certain libraries I wanted to use (eg. The MVVM dialogs library) could not be used and it wasn't clear what would work in a WASM browser environment and what wouldn't. Which leads to ...
      • Documentation is lacking in some areas. What really stumped me for a while was how do a TabControl bound to a collection of polymorphic or heterogenous tab view models. Their provided examples completely failed to tell me how to do this. I suppose if I came into this with existing WPF experience, this wouldn't have been so difficult as most of the concepts and patterns seem to be mostly transferable, but I happened to have skipped WPF and its bajillion XAML-based derivatives, so I didn't have this pre-existing knowledge to fall back on. Through perseverance and looking at the source code for many existing Avalonia applications on GitHub, I was finally able to determine that data templates was the solution.
      So all-in-all, this was a fun and useful exercise and you get a useful starting point app from this effort!
      Now I better get back onto this MapGuide/FDO work.

    • sur GIScussions: Your Map Inside

      Publié: 21 March 2024, 5:47pm CET

      A few weeks ago I recorded a Geomob Podcast with Ana Lucía González Paz about her beautiful flipbook, A Map Inside. You can read the book in a few minutes and then you can listen to the podcast

      [https:]]

      Towards the end of each podcast, I give my guest the opportunity to go off piste and talk about a subject that they choose (in the past we have talked about digital privacy, mental health and open source sustainability to mention just a few). Ana said that she would like to ask me to describe my Map Inside and you can hear how I replied at the end of the podcast.

      After we recorded the podcast, I was chatting with Ana and we thought that it would be fun to get other people to share their Map Inside. Everyone has a Map Inside connected to memories, people, special moments, would you like to share yours? Just record a short audio clip in mp3 format running for 60 to 120 seconds and mail it to me (if you don’t know my email use the Contact Form to reach me or find me at Mastodon). Assuming we get a few responses, Ana and I will put together an episode of the podcast with a selection of your Maps Inside.

      Hope to hear from you with your Map Inside

      geomob hero image

      Earlier this week an episode of the Geomob Podcast was published where Steven Feldman interviews yours truly. It was a lot of fun to chat with Steven about Elastic, my experience in the geospatial industry, and Open Source in general. I could also advocate a bit about data privacy and digital identity which is a topic that has picked my interest even more lately with all the shit that is hitting that social network we all know about.

      If you want to learn a bit about Elastic and Geo this is maybe a good opportunity to get a condensed gist of why would anyone want to store and analyze geospatial data in Elasticsearch, a few compelling use cases and so on.

      Publié: 19 March 2024, 1:00am CET

      GeoServer 2.25.0 release is now available with downloads (bin, war, windows), along with docs and extensions.

      This is a stable release of GeoServer recommended for production use. GeoServer 2.25.0 is made in conjunction with GeoTools 31.0, and GeoWebCache 1.25.0.

      Thanks to Peter Smythe for making this release. Thanks to Levy Steve, Peter Smythe, Jody Garnett, and Mark Prins for testing the 2.25.0 release.

      Security Considerations

      This release addresses several security vulnerabilities, all of which require admin access.

      • If you have updated to GeoServer 2.24.2 Release or GeoServer 2.23.5 Release you are already patched.
      • If you are working with a commercial support provider that volunteers with the geoserver-security email list they are already informed.

      Vulnerabilities:

      • CVE-2023-51444 Arbitrary file upload vulnerability in REST Coverage Store API (High).
      • CVE-2023-41877 GeoServer log file path traversal vulnerability (High).
      • CVE-2024-23634 Arbitrary file renaming vulnerability in REST Coverage/Data Store API (Moderate).
      • CVE-2024-23643 Stored Cross-Site Scripting (XSS) vulnerability in GWC Seed Form (Moderate).
      • CVE-2024-23821 Stored Cross-Site Scripting (XSS) vulnerability in GWC Demos Page (Moderate).
      • CVE-2024-23819 Stored Cross-Site Scripting (XSS) vulnerability in MapML HTML Page (Moderate).
      • CVE-2024-23818 Stored Cross-Site Scripting (XSS) vulnerability in WMS OpenLayers Format (Moderate).
      • CVE-2024-23642 Stored Cross-Site Scripting (XSS) vulnerability in Simple SVG Renderer (Moderate).
      • CVE-2024-23640 Stored Cross-Site Scripting (XSS) vulnerability in Style Publisher (Moderate).
      • CVE-2023-51445 Stored Cross-Site Scripting (XSS) vulnerability in REST Resources API (Moderate).

      We would like to thank everyone who contributed to reporting, verifying and fixing the above vulnerabilities (see each CVE for appropriate credits). A special thank you to Steve Ikeoka for reporting most of the issues and doing the majority of the actual fixes.

      The use of the CVE system allows the GeoServer team to reach a wider audience than blog posts. See the project security policy for more information on how security vulnerabilities are managed.

      Upgrade Notes

      We have a number of configuration changes when updating an existing system:

      • The longstanding ENTITY_RESOLUTION_ALLOWLIST setting has been recommended as a way to control the locations available for external entity resolution when parsing XML documents and requests.

        The default has changed from * (allowing any location) to allowing the recommended www.w3.org, schemas.opengis.net, www.opengis.net locations used for OGC Web Services, along with the inspire.ec.europa.eu/schemas location used by our friends in Europe.

      • The FreeMarker Template HTML Auto-escaping is now enabled by default.

      • The spring security firewall is now enabled by default.

      • A new configuration setting is available to limit content served from the geoserver/www folder.

        If you have not met the www folder before it is used to share content, and there is a tutorial serving static files.

      • We do add recommendations to production considerations over time, if you have not checked that page in a while please review.

      Thanks to Steve Ikeoka and Jody Garnett for these improvements.

      JTS fast polygon intersection enabled by default

      The JTS Next Generation polygon intersection algorithm has been enabled by default, which will improve performance of a number of operations, including WPS processes and the vector tiles generation. We deem the functionality well tested enough that it should be opened to the majority of users, even if it’s still possible to turn it off by adding the -Djts.overlay=old.

      MapML Extension

      The MapML extension is receiving a number of updates and improvements, with more to come in the following months. It’s now possible to declare “Tiled CRS” as the CRS for a layer, with the implication not just of the CRS, but also of the gridset that will be used by the MapML viewer:

      This portion builds on top of the work done months ago to support astronomical CRSs, which allows GeoServer to support multiple CRS authorities.

      The MapML preview links are now using the new MapML output format, while the old dedicated REST controller has been removed. This allows for better integration of the MapML format in the GeoServer ecosystem. The MapML viewer has also been updated to the latest version:

      Thanks to Joseph Miller and Andrea Aime (GeoSolutions) for this work, and Natural Resources Canada for sponsoring it.

      Community Module Updates

      Much of the new activity in GeoServer starts as a community module. We’d like to remind you that these modules are not yet supported, and invite you to join the effort by participating in their development, as well as testing them and providing feedback.

      Raster Attribute Table community module

      Developed as part of GEOS-11175, the Raster Attribute Table community module uses the GDAL Raster Attribute Table (RAT) to provide a way to associate attribute information for individual pixel values within the raster, to create styles as well as to provide a richer GetFeatureInfo output.

      For more information see the user guide.

      We’d like to thank Andrea Aime (GeoSolutions) for the development and NOAA for sponsoring.

      Graticules for WMS maps

      The graticules community module, developed as part of GEOS-11216, provides a datastore generating graticules for WMS maps, along with a rendering transformation that can be used to label them. The module can be used to draw a graticule in WMS maps, as well as to download them as part of WFS (or in combination with the WPS download module).

      We’d like to thank Ian Turton for development and GeoSolutions for sponsoring the work.

      GeoServer monitor Kafka storage

      The monitoring Kafka storage module, developed as part of GEOS-11150, allows storing the requests captured by the monitoring extension into a Kafka topic.

      We’d like to thank Simon Hofer for sharing his work with the community. To learn more about the module, how to install and use it, see the user-guide.

      JWT Headers

      The JWT headers module has been developed as part of GEOS-11317.

      The module is a new authentication filter that can read JWT Headers, as well as general JSON payloads and simple strings, to identify a user, as well as to extract their roles. The combination of Apache mod_auth_openidc with geoserver-jwt-headers-plugin provides an alternative to using the geoserver-sec-oauth2-openid-connect-plugin plugin.

      We’d like to thank David Blasby (GeoCat) for this work on this module.

      Developer Updates ResourceStore / Paths API Change

      Developers should keep in mind some important maintenance work performed by Niels Charlier on the use absolute and relative paths in the ResourceStore. See the Developers Guide for more information.

      This does not affect end users.

      Experimental Java 21 support

      GeoServer, along with GeoTools and GeoWebCache, are now tested to build and pass tests with Java 21.

      This is not yet an endorsement to run GeoServer in production with Java 21. We are looking ahead at the 2024 roadmap, and are making sure the basics are covered for the newer Java releases.

    • sur Free and Open Source GIS Ramblings: Getting started with pygeoapi processes

      Publié: 18 March 2024, 8:16pm CET

      Today’s post is a quick introduction to pygeoapi, a Python server implementation of the OGC API suite of standards. OGC API provides many different standards but I’m particularly interested in OGC API – Processes which standardizes geospatial data processing functionality. pygeoapi implements this standard by providing a plugin architecture, thereby allowing developers to implement custom processing workflows in Python.

      I’ll provide instructions for setting up and running pygeoapi on Windows using Powershell. The official docs show how to do this on Linux systems. The pygeoapi homepage prominently features instructions for installing the dev version. For first experiments, however, I’d recommend using a release version instead. So that’s what we’ll do here.

      As a first step, lets install the latest release (0.16.1 at the time of writing) from conda-forge:

      conda create -n pygeoapi python=3.10
      conda activate pygeoapi
      mamba install -c conda-forge pygeoapi

      Next, we’ll clone the GitHub repo to get the example config and datasets:

      cd C:\Users\anita\Documents\GitHub\
      git clone [https:] 
      cd pygeoapi\

      To finish the setup, we need some configurations:

      cp pygeoapi-config.yml example-config.yml  
      # There is a known issue in pygeoapi 0.16.1: [https:] 
      # To fix it, edit the example-config.yml: uncomment the TinyDB option in the server settings (lines 51-54)

      $Env:PYGEOAPI_CONFIG = "F:/Documents/GitHub/pygeoapi/example-config.yml"
      $Env:PYGEOAPI_OPENAPI = "F:/Documents/GitHub/pygeoapi/example-openapi.yml"
      pygeoapi openapi generate $Env:PYGEOAPI_CONFIG --output-file $Env:PYGEOAPI_OPENAPI

      Now we can start the server:

      pygeoapi serve

      And once the server is running, we can send requests, e.g. the list of processes:

      curl.exe [localhost:5000]

      And, of course, execute the example “hello-world” process:

      curl.exe --% -X POST [localhost:5000] -H "Content-Type: application/json" -d "{\"inputs\":{\"name\": \"hi there\"}}"

      As you can see, writing JSON content for curl is a pain. Luckily, pyopenapi comes with a nice web GUI, including Swagger UI for playing with all the functionality, including the hello-world process:

      It’s not really a geospatial hello-world example, but it’s a first step.

      Finally, I wan’t to leave you with a teaser since there are more interesting things going on in this space, including work on OGC API – Moving Features as shared by the pygeoapi team recently:

      So, stay tuned.

    • sur Ecodiv.earth: Download AHN data in GRASS GIS

      Publié: 17 March 2024, 12:00am CET

      The AHN

      The ‘Actueel Hoogtebestand Nederland’ (AHN, version 4) is the latest digital elevation model (DEM) of the Netherlands. It includes a digital terrain model (DTM) and a digital surface model (DSM). The former represents the bare ground surface without any features such as buildings, vegetation, or other structures, while the latter includes these features.

      Both layers can be downloaded at 0.5 or 5 meter resolution in tiles of 6.5 by 5 km. Downloading one tile, which is approximately 500 MB, is doable. However, if you need more tiles, the arguably easier way is to download the data using the WCS (Web Coverage Service) protocol, which allows you to choose what part of the available data to download based on spatial constraints.

      Import the DTM

      This example shows the steps to download the 0.5 meter resolutiom DTM for the Land van Cuijk, a municipality in which our research group Climate-robust Landscapes is carrying out several studies. The first step is to get the r.in.wcs addon. With this addon, you can use the WCS protocol to download data 1 2.

      Install the r.in.wcs addon.

      First step is to import the Python libraries. Note, this will not be repeated with the next scripts.

      import grass.script as gs

      Now, you can install the r.in.wcs addon using the g.extension function.

      gs.run_command("g.extension", extension="r.in.wcs")

      You need the g.extension function to install addons. In the main menu, go to Settings > Addons extension > Install extension from addon. Alternatively, type in g.extension on the command line. This will open the window shown below.

      The g.extension function, started from the command line.

      The g.extension function, started from the command line.

      The r.in.wcs addon imports the raster layers using the resolution and extent of the current region. A crucial step, therefore, is to set the extent and resolution of the region so that it aligns perfectly with that of the AHN layer.

      Set the extent and resolution to match those of the AHN.

      gs.run_command("g.region",
    n=618750, 
    s=306250, 
    w=10000, 
    e=280000, 
    res=0.5)

      Type in g.region on the command line or in the console. You can also find the function under main menu > Settings > Computational region > set region. This opens the following screen:

      Set the bounds

      Set the bounds

      Set the resolution

      Set the resolution

      With this settings, you align the region with the AHN data set.

      Next, download the administrative boundaries of the Dutch municipalities, and extract the boundaries of the “Land van Cuijk”.

      Download layer with administrative boundaries of the neighborhood.

      gs.run_command(
    "v.in.wfs",
    url="https://service.pdok.nl/cbs/wijkenbuurten/2022/wfs/v1_0?",
    output="municipalities",
    name="gemeenten",
)

      Next, extract the boundaries of the municipality of “Land van Cuijk”

      gs.run_command(
    "v.extract",
    input="municipalities",
    where="naam = 'Land van Cuijk'",
    output="LandvanCuijk",
)

      Type in v.in.wfs on the command line or in the console. You can also find the function under main menu > File > Import vector data. This opens the following screen (you need to fill in parameters in two tabs):

      Download the vector layer with the municipality boundaries. Define the base URL and the name of the output layer.

      Download the vector layer with the municipality boundaries. Define the base URL and the name of the output layer.

      Download the vector layer with the municipality boundaries. Fill in the name of the WFS layer to download.

      Download the vector layer with the municipality boundaries. Fill in the name of the WFS layer to download.

      Extract the boundaries of the municipality of Land van Cuijk. Select the name of the vector layer with municipalities and give the name of the output layer.

      Extract the boundaries of the municipality of Land van Cuijk. Select the name of the vector layer with municipalities and give the name of the output layer.

      Extract the boundaries of the municipality of Land van Cuijk. Fill in the query, which defines which features you want to select and save. Tip: Use the convenient query builder.

      Extract the boundaries of the municipality of Land van Cuijk. Fill in the query, which defines which features you want to select and save. Tip: Use the convenient query builder.

      Now, you can set the region to match the extent of the vector layer, while taking care that the region aligns perfectly with the DTM.

      Set the region to the correct extent and resolution.

      First, get the north, south, east, and west coordinates of the bounding box of the vector layer and of the region’s extent.

      region_tiles = gs.parse_command("g.region", 
    flags="gu")
region_munic = gs.parse_command("v.info", 
    flags="g", 
    map="LandvanCuijk")

      Now, adjust the northern boundary of the bounding box of the vector layer so that it aligns with the AHN tiles.

      from math import floor

n = float(region_tiles["n"]) - floor(
    (float(region_tiles["n"]) - float(region_munic["north"]))
)
s = float(region_tiles["s"]) + floor(
    (float(region_munic["south"]) - float(region_tiles["s"]))
)
w = float(region_tiles["w"]) + floor(
    (float(region_munic["west"]) - float(region_tiles["w"]))
)
e = float(region_tiles["e"]) - floor(
    (float(region_tiles["e"]) - float(region_munic["east"]))
)
gs.run_command("g.region", n=n, s=s, e=e, w=w)

      And finally, import the DTM layer. Warming, this may take some time.

      Import the DTM for the defined region.

      gs.run_command(
    "r.in.wcs",
    url="https://service.pdok.nl/rws/ahn/wcs/v1_0?",
    coverage="dtm_05m",
    urlparams="GetMetadata",
    output="dtm_05",
)

      The maximum floating-point value (3.4028235e+38) is not recognized as a NULL value. So use the setnull parameter in the r.null function to specify that this value has to be set to NULL.

      gs.run_command("r.null", 
    map="dtm_05", 
    setnull=3.4028235e+38)

      If this does not work (it didn’t for me), you can use the r.mapcalc function to set this value to NULL.

      gs.run_command("r.mapcalc", 
    expression="dtm_05m = if(dtm_05m > 1000,null(),dtm_05m)",
    overwrite=True)

      Fill in the WCS service URL

      Fill in the WCS service URL

      Get the overage name to request

      Get the overage name to request

      To make it a bit easier, I combined steps 2, 4, and 5 in a new addon r.in.ahn. It is a bit rough around the edges (it only works in a Location with CRS RD New), but it serves its goal. I have submitted it to the GRASS GIS addon repository, so I hope it will be available in a week or so.

      Footnotes

      1. You are expected to be familiar with GRASS GIS and the concept of region used in GRASS GIS. If you are new to GRASS GIS, you are warmly recommended to first check out the GRASS GIS Quickstart and the explanation about the GRASS GIS database.??

      2. Downloading the DTM for the whole municipality will take a while. If you want to speed up things, you can work with a smaller area by using your own vector data.??

    • sur Registration opens for OGC Innovation Days Europe 2024

      Publié: 14 March 2024, 2:00pm CET par Simon Chester

      The Open Geospatial Consortium (OGC) is excited to announce that registration is open for OGC Innovation Days Europe. Held in conjunction with FOSS4G Europe 2024, on July 1-2, in Tartu, Estonia, the event will focus on themes of Climate and Disaster Resilience, One Health, and the corresponding Data Spaces. Registration is available here.

      OGC Innovation Days Europe seeks to address stakeholders’ and policymakers’ need for digital solutions that can meet their requirements efficiently and in a user-friendly way. To this end, the event will bring internationally leading software development and data management experts together with non-technical experts – such as urban planners, policy makers, economists, and other beneficiaries of geospatial information – to exchange information and learn from each other. The stakeholders’ needs will be discussed and understood in depth while newly developed prototypes will be presented.

      OGC is co-organizing Innovation Days Europe with the General Authority for Survey and Geospatial Information (GEOSA, Saudi Arabia) and FOSS4G-Europe.

      The European IT landscape is changing rapidly. Several initiatives are underway, such as developing Data Spaces and Digital Twins, supporting the Green Deal, or otherwise trying to integrate the largely heterogeneous IT landscape. What do these mean for the leading challenges of our century? How can these predominantly technologically oriented efforts help with climate change and disaster resilience? Do they support Land Degradation Neutrality?

      OGC Innovation Days Europe provides a platform to discuss how current technical efforts can be combined effectively with the necessary governance and policy aspects. What decision processes do we need? What agreements are required for efficient decision processes or homogeneous reporting models for, for example, Climate Change or Land Degradation Neutrality?

      Thematic focus: Climate and Disaster Resilience, One Health, and Data Spaces.

      Achieving climate and disaster resilience and sustainability requires reliable location information on the environment, land, and climate. Generating this information dedicated to the users’ needs is challenging. It needs highly optimized spatial data infrastructures and climate resilience information systems operated within a targeted policy framework and driven by an efficient policy model. Interoperable data pipelines and well-organized data spaces with their data assessment applications, combined with analysis, visualization, and reporting tools, are required to gain the knowledge to enroll climate strategies and actions.

      OGC Innovation Days Europe will foster a dialogue between technical experts, decision-makers, and policy experts, with a focus on climate & disaster resilience, one health, the role of data spaces, and the need for modernized knowledge exchange and analysis environments.

      OGC Innovation Days Europe supports the shift in IT solutions from being purely technology-oriented to a more holistic approach that better accounts for the various needs of the stakeholders. The event will identify these needs and thus make an essential contribution to improving the direction of future technological developments, supporting operational setups that are driven by efficient governance models and that operate within a solution-oriented policy framework.

      OGC Innovation Days Europe 2024 is sponsored by OGC, the General Authority for Survey and Geospatial Information, Saudi Arabia, and the European Commission through the Horizon projects CLINT (GA-101003876), AD4GD (GA-101061001), USAGE (GA-101059950), Iliad (GA-101037643), EuroGEOSec (GA-101134335), CLIMOS (GA-101057690) and other projects of the Climate-Health Cluster.

      OGC Innovation Days Europe will run in conjunction with FOSS4G Europe 2024 from July 1-2, in Tartu, Estonia. Learn more and register on the FOSS4G Europe 2024 website.

    • sur Fernando Quadro: Raster no PostGIS, vale a pena?

      Publié: 14 March 2024, 1:00pm CET

      Você sabe quais os benefícios e as armadilhas de colocar arquivos rasters em um banco de dados relacional?

      A maioria das pessoas pensa que “colocar em um banco de dados” é uma receita mágica para: desempenho mais rápido, escalabilidade infinita e gerenciamento fácil.

      Se você pensar que o banco de dados está substituindo uma pilha de arquivos CSV, isso provavelmente é verdade.

      Porém quando o banco de dados está substituindo uma coleção de arquivos de imagens GeoTIFF, isso provavelmente é falso. O raster no banco de dados será mais lento, ocupará mais espaço e será muito chato de gerenciar.

      Então, por que fazer isso? Comece com um padrão, “não!”, e então avalie a partir daí.

      Para alguns dados raster não visuais e casos de uso que envolvem o enriquecimento de vetores de fontes raster, ter o raster colocalizado com os vetores no banco de dados pode tornar o trabalho com ele mais conveniente. Porém, ainda será mais lento que o acesso direto e ainda será difícil de gerenciar, mas permite o uso de SQL como uma linguagem de consulta, o que pode oferecer muito mais flexibilidade para explorar o espaço da solução do que um script de acesso a dados criado especificamente para esse fim.

      La mostra è stata organizzata dai Musei Reali di Torino, dalla Direzione Regionale Musei Piemonte e dal Museo di Antropologia ed Etnografia dell’Università di Torino, ed è una intensa passeggiata nel voyeurismo e collezionismo italiano durante il lungo periodo della scoperta, conquista e razzia dell’Africa, fino agli orrori della guerra in Etiopia. Il percorso si snoda sui passi di molti personaggi, tutti uomini italiani: esploratori, ingegneri al servizio dell’espansione belga nel Congo, affaristi, membri della casa reale. Tutti accomunati dall’attività coloniale nelle sue diverse fasi storiche, e tutti prontamente rimossi dalla memoria collettiva al termine della seconda guerra mondiale. Altrettanto dimenticate le collezioni di oggetti africani che questi personaggi hanno fatto confluire a vario titolo nei musei italiani e in questo caso piemontesi.

      Ad accompagnare la visita le installazioni di Bekele Mekonnen, in particolare il “site specific” dal titolo “The smoking table” ma anche le clip sonore lungo il percorso.

      La mostra ha agitato tantissimo i fascisti dichiarati e quelli non dichiarati perché non usa giri di parole, perché chiama il colonialismo e il razzismo con il loro nome, perché mette le voci africane sullo stesso piano di quelle italiane. Il ricco programma pubblico ha coinvolto molte persone, anche originarie dell’Africa.

In rosso sotto un braccio muscoloso: conspiracy, betrayal, greed, injustice, deception. In azzurro sotto due mani strette: honesty, fraternity, generosity, impartiality”

      Le polemiche, tutte politiche e ben poco culturali, suonano come un brusio fastidioso se consideriamo il lavoro lunghissimo di preparazione della mostra, la quantità di musei con collezioni africane in tutto il Piemonte, la ricchezza del catalogo che affronta in dettaglio molte delle questioni sollevate ad arte, ad esempio il salario pagato ai lavoratori della Società Agricola Italo-Somala, veri “forzati della terra” anche nelle parole degli italiani dell’epoca.

      Il paradosso sta nel fatto che questa mostra è molto blanda, se la inquadriamo nella cornice europea e occidentale bianca dei musei di antropologia e archeologia: dalla complessa operazione di continuo adattamento del Musée du Quai Branly di Parigi, al documentario Dahomey di Mati Diop che ha vinto l’Orso d’oro del Festival di Berlino pochi giorni fa, per finire al lavoro avviato nel 2016 da quello che oggi si chiama Museo delle Civiltà. È molto eloquente l’intervento del direttore Andrea Villani a un convegno di poche settimane fa, che potete rivedere su YouTube. Ho apprezzato questo passaggio:

      Quello che allora aveva un senso oggi può non solo non avere un senso, ma può anche essere tossico. [..] La storia non si cambia. I musei non cambiano la storia, ma possono raccontarla per intero, accettando di mettere in crisi quello che è venuto prima

      E poiché in Italia non siamo solo colonizzatori ma anche colonizzati e depredati, è bene sapere che alcuni musei degli USA sono seriamente alle prese con la provenienza delle proprie collezioni.

      Publié: 12 March 2024, 11:00am CET

      Eric Lund said “Came across this eye-catching map at my eye doctor’s office this week and had to share it with you.” Well I am glad he did share it, what a cracking map in the wild! Here’s a bit more detail.

      This piece was designed by Tad Bradley, the accompanying description says

      ‘Snellen’ and “Tumbling E’ eye charts: Ocular Cartographic Study

      Although trained and currently practicing architecture at SMA Architecture + Design, Tad Bradley remains an artist and educator. He is continually fascinated with nature and the human body. The complexities within and between these are continually inspirational to investigate through art.
      The scale of the eye charts is inspired by the art movement of hyperrealism. In reproducing the eye charts at such a large scale, they begin to hold a greater weight within space, possibly reminding us the value of our eyesight and the incredible value this sense and these organs bring to our lives.
      The maps and text you see were originally printed in 1906. The series of oversized manuscripts, which focused on separate geographic regions, were titled ‘Geologic Atlas of the United States’, edited by S.J. Kubel. The maps here, in the waiting area, have been scanned and reprinted on metal panels in order to protect them from UV degradation from solar exposure.
      Eye charts have been the tool opticians have used for many years to assist in initially analyzing visual acuity. Exploring a tool within art invites a different awareness of not only the object but the process of how it is used. These eye charts were created for specific groups of people. The Tumbling E chart is used for those unable to read or never learned the Latin alphabet. The shapes and their direction are universal to all. The Snellen eye chart contains eleven rows of diminishing Latin letters to assess vision.
      Each 11? x 11? plywood panel has two layers of hand-cut paper [1906] to create visual contrast for viewers.
      “I chose the text pages from the Atlas to expose the Tumbling E chart. I was interested in exploring the contrast of the text-heavy pages and their visual relationship to the simplified ‘E’ shapes. The maps, on the other hand, are filled with high-contrast colors and patterns, more easily revealing the letters of the Snellen eye chart.
      One of my goals in creating this work was to analyze how we as humans experience the world, interact with one another, and stand alone as individuals. I hope that my work creates curiosity, questions and conversation”.

    • sur Fernando Quadro: Por que usar o PostGIS?

      Publié: 11 March 2024, 1:00pm CET

      Talvez você já tenha escutado algumas vezes a frase: “PostGIS é uma extensão espacial do PostgreSQL”.

      Isso não significava que você tivesse ou tenha alguma ideia do que isso significa, e que você sabia o que é o PostgreSQL, quiçá o PostGIS.

      Mas não se preocupe, você não sairá desse post sem saber o que é cada um deles.

      PostGIS é um extensor de banco de dados espacial de código aberto e disponível gratuitamente para o PostgreSQL Database Management System (também conhecido como DBMS). Portanto, PostgreSQL (também conhecido como Postgres) é o banco de dados e PostGIS é como um complemento desse banco de dados.

      Resumidamente, o PostGIS adiciona funções espaciais, como distância, área, união, interseção e tipos de dados de geometria ao PostgreSQL. Os bancos de dados espaciais armazenam e manipulam objetos espaciais como qualquer outro objeto no banco de dados.

      ? E qual a vantagem de utilizá-lo?

      Na prática temos algumas vantagens em utilizá-los, mas a principal é a possibilidade de trabalhar com grandes conjuntos de dados. Não é apenas mais fácil, mas às vezes é quase impossível trabalhar em conjuntos de dados maiores sem um banco de dados.

      ?Você já tentou abrir um arquivo CSV de 2 GB?
      ?Ou tentou fazer algum geoprocessamento para um GeoJSON de 800 mb?
      ?Você sabia que os Shapefiles têm um limite de tamanho?

      É claro que você pode resolver alguns desses problemas usando o Geopackage ou alguns outros formatos de arquivo, mas em geral o PostGIS é a ferramenta ideal para lidar com grandes volumes de dados (geoespaciais).

      Publié: 10 March 2024, 7:08pm CET

      Ieri sera siamo andati al Teatro Gustavo Modena, qui vicino a casa, per uno spettacolo della stagione dedicata all’infanzia. Eravamo con altre famiglie, ci siamo persino fatti un aperitivo casalingo prima di andare, visto che iniziava alle sette e mezza.

      Lo spettacolo si intitola “In…segnami il silenzio” e ha come protagonisti Marcello e Maria. Marcello ci racconta dell’arrivo di Maria nella sua classe, lei non parla e non sente, perché ha le “orecchie rotte”. Maria però sa ascoltare con gli occhi e sa parlare con la danza delle mani, con il viso, con tutto il corpo. Il rapporto tra Marcello e Maria è molto profondo, lui si lascia trasportare e insegnare. In cambio le fa vedere la musica che lei non può sentire, in particolare sulle note di una travolgente “Ça plane pour moi”.

      Lo spettacolo è rivolto ai bambini anche se non è facilissimo, ma tratta in modo fiabesco, senza filtri e un po’ scanzonato il tema della disabilità, che non è solo la sordità di Maria ma anche la “distrazione” di Marcello che la maestra gli rimprovera.

      Ci è piaciuto molto.

      Alla fine un appello della regista Elena Dragonetti per il cessate il fuoco a Gaza è stato accolto da un lungo applauso.

      Publié: 8 March 2024, 1:00pm CET

      Dispositivos de rastreamento de localização, como GPS, são hoje amplamente utilizados em smartphones e veículos. Como resultado, os dados de trajetória geoespacial estão atualmente sendo coletados e usados ??em muitos domínios de aplicação. O MobilityDB fornece o suporte de banco de dados necessário para armazenar e consultar esses dados de trajetória geoespacial.

      MobilityDB é implementado como uma extensão do PostgreSQL e PostGIS. Ele implementa tipos de banco de dados persistentes e operações de consultas para gerenciar trajetórias geoespaciais e suas propriedades que variam no tempo.

      Uma trajetória geoespacial é geralmente coletada como uma sequência de pontos de localização e informações de data e hora. Na realidade, porém, o movimento é contínuo. Portanto, o MobilityDB interpola a trilha de movimento entre as informações de entrada. Como tal, a localização e as propriedades do objeto em movimento podem ser consultadas, efetivamente aproximadas, a qualquer momento.

      Embora esta interpolação restaure a continuidade do movimento, ela não corresponde a um aumento no tamanho do armazenamento. Pelo contrário, permite descobrir informações redundantes e removê-las. Assim, apenas as informações onde ocorre uma mudança significativa na velocidade/direção são retidas. Esse processo é chamado de normalização e geralmente resulta em uma redução significativa no tamanho do armazenamento em comparação com os pontos de entrada.

      ? Mas na prática, como funciona esse gerenciamento realizado pela extensão?

      ?Pense em obter a velocidade média de um trem em movimento, sem nenhum código SQL longo, usando uma função e pronto.
      ?Ou em armazenar dados GPS de forma muito compacta em uma única linha/coluna e ser capaz de fazer consultas complexas com muito pouco SQL.

      É essa praticidade que o MobilityDB vai te proporcionar.

      GeoSpatial Techno is a startup focused on geospatial information that is providing e-learning courses to enhance the knowledge of geospatial information users, students, and other startups. The main approach of this startup is providing quality, valid specialized training in the field of geospatial information.

      ( YouTube | LinkedIn | Facebook | Reddit | X )

      Publishing a GeoTIFF file in GeoServer

      In this session, we want to talk about “How to Publish a GeoTIFF file in GeoServer” comprehensively. If you want to access the complete tutorial, simply click on the link.

      Introduction

      The GeoTIFF is a widely used geospatial raster data format, it is composed of a single file containing both the data and the georeferencing information. By default, GeoTIFF will be an option in the Raster Data Sources list when creating a new data store.

      Note. In this blog post, we used GeoServer version 2.20.0.

      Add a GeoTIFF data

      To add a GeoTIFF data in GeoServer, follow these steps:

      • Navigate to Data > Stores page, then click on the Add new Store link.
      • Select the desired workspace from the drop-down menu.
      • Enter the Data Source Name, make sure the Enabled option is checked. If checked, it enables the store. If unchecked (disabled), no data in the GeoTIFF will be served from GeoServer.
      • In the URL under the Connection Parameters, browse to the location of the GeoTIFF file then press the Save button.
      • Now you will be redirected to the New Layer page automatically and to add a layer for an available resource click on the Publish link.
      • Check the Name, Coordinate Reference Systems and the Bounding Boxes fields are properly set and press the Save button.
      Layer Groups

      In Geoserver, a layer group serves as a convenient container for organizing layers and other layer groups in a structured hierarchy. By assigning a single layer to a layer group in WMS requests, the process of making requests is simplified as instead of specifying multiple individual layers, only one layer needs to be indicated. Furthermore, a layer group establishes a set order for the layers within it and enables the specification of alternative styles for the layers, distinct from their default settings.

      Add a Layer Group

      • To create a Layer Groups, navigate to Data > Stores page. Click on Add a new layer group link. The initial fields allow you to configure the name, title, abstract and workspace of the layer group. Enter the Data Source Name and Title.

      • The Enabled checkbox, if disabled, will cause the layer group to just show up at configuration time, while the Advertised checkbox, if unchecked, will make it to not be available in GetCapabilities request and in the layer preview. The behaviour of layer group regarding both checkboxes will not affect the behaviour of any of the layers being grouped, which will follow respectively that specified in the corresponding edit page.

        Note. In the layer group section, Workspace selection is optional.

      • The Bound section contain the data BoundingBox of this layer group in the native coordinate reference system. The input can be done manually or automatically with the help of Generate Bounds.

        Note. By default, a layer group is queryable when at least a child layer is queryable. Uncheck Queryable box if you want to explicitly indicate that it is not queryable independently of how the child layers are configured.

      • To add more layers to the Layer Group list, you can press the Add Layer… button at the top of the table. From the popup window, select the layer to be added by clicking the layer name.

      • A layer group can be added by pressing the Add Layer Group… button at the top of the table. From the list of layer groups, select the appropriate layer group’s name.

      • A style group is a style that has one or more Named Layers which reference layers that exist in the catalog. Style groups can be added to Layer Groups as an alternative way of defining a collection of styled layers. To add it, press the Add Style Group… button at the top of the table and from the popup window, select the style group to be added by clicking its name.

      • Press the generate bounds button to have geoserver compute the group bounds from the layers inside of it.

        Note. A layer group can contain layers with dissimilar bounds and projections. GeoServer automatically reprojects all layers to the projection of the layer group.

      • When a layer group is processed, the layers are rendered in the order provided, so the publishable elements at the bottom of list will be rendered last and will show on top of the others. A publishable element can be positioned higher or lower on this list by pressing the green up or down arrows, respectively, or can be simply dragged in the target position.

      • Metadata links allows linking to external documents that describe the data of layer group. Keywords make possible to associate a layer group with some keywords that will be used to assist catalog searching.

      • Press Save button to create the new layer group.

      Preview a Layer Group

      So in order to preview the created layer, navigate to the Data > Layer Preview page and enter the name of your layer group in the search box, then press Enter button. Click on the OpenLayers link for a given layer and the view will display. An OpenLayers map loads in a new page and displays the group layer with the default styles. You can use the Preview Map to zoom and pan around the dataset, as well as display the attributes of features by click on each feature.

      Using WMS layers in QGIS

      To display a WMS layer in QGIS software, follow these steps:

      • Open GQIS and navigate to Layer > Add Layer > Add WMS/WMTS Layer.
      • To create a new service connection, from the Layers tab, press New button.
      • Name your connection from the Connection Details. Next, from the URL textbox, you need to access a WMS layer as HTTP address of Web Map Server. In this case, name the connection as My Project and the URL as http://localhost:8080/geoserver/project/wms and press OK. Note that the “project” refers to the workspace defined in Geoserver.
      • Press the Connect button to fetch the list of layers available, then press Add button and Close.
      • Now, you will see the layer loaded in the QGIS canvas. You can zoom/pan around just like any other layer. The way WMS service works is that every time you zoom/pan, it sends your viewport coordinates to the server and the server creates an image for that viewport and return it to the client. So there will be some delay before you see the image for the area after you have zoomed in. Also, since the data you see is an image, there is no way to query for attributes like in a regular vector/imagery layer.

    • sur Fernando Quadro: Comparando GeoNode e ArcGIS Online: Qual é o certo para você?

      Publié: 7 March 2024, 1:00pm CET

      GeoNode e ArcGIS Online são plataformas de software GIS (Geographic Information System) que permitem a criação e o compartilhamento de mapas e aplicativos web. No entanto, existem diferenças importantes entre as duas plataformas que podem influenciar na escolha da solução mais adequada para suas necessidades. Este artigo tem como objetivo fornecer uma comparação entre essas plataformas, com foco em recursos, funcionalidades e sua adequação para instituições governamentais, empresariais e acadêmicas.

      ? Funcionalidades

      O Geonode é uma plataforma open-source com foco na catalogação, visualização e compartilhamento de dados geoespaciais, que apresenta facilidade de uso, gerenciamento e integração com diversas ferramentas e serviços web OGC (Open Geospatial Consortium).

      O ArcGIS Online é uma plataforma robusta para criação de mapas e aplicativos WebGIS que possui uma ampla gama de funcionalidades para análise espacial, geoprocessamento e gerenciamento de dados, além da integração com outras plataformas ArcGIS e ferramentas da Esri.

      ? Curva de aprendizado

Além disso, o Geonode possui uma curva de aprendizado mais suave para usuários com pouca ou nenhuma experiência em GIS.

      O ArcGIS Online é uma plataforma mais complexa, com uma curva de aprendizado mais acentuada, o que requer conhecimentos técnicos em GIS para configuração, administração e desenvolvimento de aplicações. Essa plataforma possui documentação extensa e abrangente, com diversos recursos de aprendizado.

      ? Documentação

      A documentação do Geonode é recomendada para usuários iniciantes em GIS que buscam uma documentação mais simples e direta e para usuários que desejam configurar e usar a plataforma rapidamente.

      O ArcGIS Online é recomendado para usuários experientes em GIS que buscam uma documentação completa e abrangente e para usuários que desejam explorar todos os recursos da plataforma.

      ? Taxas de licenciamento e custos de assinatura

      GeoNode: Sendo de código aberto, o GeoNode é totalmente gratuito para baixar, usar e modificar. Não há taxas de licenciamento ou custos de assinatura associados ao uso da plataforma.

      ArcGIS Online: O ArcGIS Online exige uma taxa de licenciamento, que pode ser substancial, especialmente para organizações maiores ou com necessidades complexas de GIS. Além disso, poderão ser incorridos custos contínuos de assinatura para acesso a atualizações e suporte.

      ? Personalização e Desenvolvimento

      O GeoNode: A natureza de código aberto do GeoNode permite ampla personalização e desenvolvimento. As organizações podem adaptar a plataforma às suas necessidades específicas sem incorrer em custos adicionais com ferramentas de desenvolvimento proprietárias.

      ArcGIS Online: A personalização no ArcGIS Online pode exigir o uso de ferramentas e APIs proprietárias, potencialmente levando a taxas de licenciamento ou custos de desenvolvimento
      adicionais.

      ? Escalabilidade e flexibilidade

      GeoNode: A escalabilidade do GeoNode não está vinculada a níveis de licenciamento ou níveis de assinatura. As organizações podem dimensionar a implantação do GeoNode conforme necessário, sem incorrer em custos adicionais de licenciamento.

      ArcGIS Online: O dimensionamento do ArcGIS Online pode exigir a compra de licenças adicionais ou níveis de assinatura, o que pode se tornar caro à medida que as necessidades de GIS de uma organização aumentam.

      ? Mas enfim, quando devo usar cada uma das ferramentas?

      Use o GeoNode se fizer parte de uma pequena, média ou grande organização com necessidades essenciais de mapeamento e compartilhamento de dados geoespaciais e que, além disso, busque uma solução open-source, fácil de usar e sem custos de licenças.

      Use o ArcGIS Online se fizer parte de uma grande organização com recursos que possua necessidades complexas de GIS e que busquem uma plataforma robusta e com ampla gama de funcionalidades para usuários que já estão familiarizados com outras plataformas ArcGIS e ferramentas da Esri.

      WebGIS é uma tecnologia usada para exibir e analisar dados espaciais na Internet. Ele combina as vantagens da Internet e do GIS oferecendo um novo meio de acessar informações espaciais sem a necessidade de você possuir ou instalar um software GIS.

      A necessidade de divulgação de dados geoespaciais têm estimulado cada vez mais o uso de ferramentas WebGIS para apresentações interativas de mapas e de informações relacionadas por meio da internet.

      As soluções adotadas na apresentação destes mapas devem apresentar um equilíbrio entre facilidade de uso, riqueza de recursos para visualização e navegação entre os dados, e funcionalidades geoespaciais para pós-processamento, características que devem ser adequadas para cada perfil de usuário que acessará o WebGIS.

      Publié: 4 March 2024, 10:47am CET

      Venerdì 1 marzo ero a Savona per parlare di transizione energetica dal basso alla Società di Mutuo Soccorso Fornaci, insieme al gruppo territoriale di ènostra. Ci avevano invitati il comitato No rigassificatore e il comitato Fermiamo il mostro per una serata insieme a due associazioni genovesi con cui collaboriamo spesso, Cittadini sostenibili e CER Sole.

      Savona e Vado Ligure non assistono passivamente alle scelte assurde dei politici regionali e locali di accogliere un rigassificatore che inquina il mare, deturpa il territorio con tutto il gasdotto necessario a terra, contribuisce a inquinare l’aria rimanendo ancorati alle fonti fossili e arricchendo le grandi multinazionali. C’è stato un risveglio che ha portato a una lunga catena umana lungo la costa, tante mobilitazioni e molti resistono all’idea di avere dei benefici “compensativi”.

      La serata è stata lunga e la partecipazione grande, nonostante la pioggia. Si è parlato dei danni che derivano dalle fonti fossili per il clima e per la salute, delle false notizie sulle rinnovabili, delle comunità energetiche. E io ho presentato le attività di ènostra. Ero piuttosto stanco ma con l’aiuto degli altri soci del gruppo territoriale ho spiegato cosa fa la cooperativa, che principi la guidano e l’importanza della partecipazione alle scelte energetiche al di là del cambio di fornitura. Non tutta l’energia rinnovabile è uguale e quella fatta dal basso, attenta agli impatti sociali e ambientali è quella che preferiamo.

      L’accoglienza del comitato è stata molto generosa e sono contento che sia nato questo legame.

    • sur GeoServer Team: GeoServer 2.25-RC Release

      Publié: 4 March 2024, 1:00am CET

      GeoServer 2.25-RC release is now available with downloads (bin, war, windows), along with docs and extensions.

      This is a release candidate intended for public review and feedback. GeoServer 2.25-RC is made in conjunction with GeoTools 31-RC, and GeoWebCache 1.25-RC.

      Thanks to Jody Garnett (GeoCat) for making this release.

      Why share a release candidate?

      A sensible question to ask is why a “release candidate” is being produced at all - when we do not recommend running such a thing in production.

      GeoServer also follows a “release early, release often” approach which is where the project shares releases so you can test and provide feedback.

      This results in a lovely balance:

      • The GeoServer developer has already tested on the data and data sources they got handy.

      • The users of GeoServer have access to a much greater variety in data and and use cases to test with.

        Please try out this release candidate and let us know how it works for you.

      • Bonus: By testing with your data directory you are assured that the next GeoServer will work well for you and your team.

      This balance of a community sharing and each doing what they can they can do easily, is a nice thing about the open-source approach: the result is software we can trust and works well.

      Thank you for being part of the GeoServer community. Testing and feedback is welcome by email and bug reports.

      Upgrade Notes

      We have a number of configuration changes when updating an existing system:

      • The longstanding ENTITY_RESOLUTION_ALLOWLIST setting has been recommended as a way to control the locations available for external entity resolution when parsing XML documents and requests.

        The default has changed from * (allowing any location) to allowing the recommended www.w3.org, schemas.opengis.net, www.opengis.net locations used for OGC Web Services, along with the inspire.ec.europa.eu/schemas location used by our friends in Europe.

      • The FreeMarker Template HTML Auto-escaping is now enabled by default.

      • The spring security firewall is now enabled by default.

      • A new configuration setting is available to limit content served from the geoserver/www folder.

        If you have not met the www folder before it is used to share content, and there is a tutorial serving static files.

      • We do add recommendations to production considerations over time, if you have not checked that page in a while please review.

      Thanks to Steve Ikeoka and Jody Garnett for these improvements.

      Security Considerations

      This a reminder to update to GeoServer 2.24.2 Release (or GeoServer 2.35.5 Release).

      Alongside the upcoming GeoServer 2.25.0 release we will “publicly disclose” a list of Common Vulnerabilities and Exposures that have been addressed previously.

      • If you are working with a commercial support provider that volunteers with the geoserver-security email list they are already informed.
      • If you have updated to GeoServer 2.24.2 Release (or GeoServer 2.23.5 Release) you are already patched.

      I hope you enjoy our team’s effort to improve communication. The use of the CVE system allows us to reach a wider audience than reads these blog posts.

      See the project security policy for more information on how security vulnerabilities are managed.

      Experimental Java 21 support

      GeoServer, along with GeoTools and GeoWebCache, are now tested to build and pass tests with Java 21.

      This is not yet an endorsement to run GeoServer in production with Java 21. We are looking ahead at the 2024 roadmap, and are making sure the basics are covered for the newer Java releases.

      JTS fast polygon intersection enabled by default

      The JTS Next Generation polygon intersection algorithm has been enabled by default, which will improve performance of a number of operations, including WPS processes and the vector tiles generation. We deem the functionality well tested enough that it should be opened to the majority of users, even if it’s still possible to turn it off by adding the -Djts.overlay=old.

      MapML Extension

      The MapML extension is receiving a number of updates and improvements, with more to come in the following months. It’s now possible to declare “Tiled CRS” as the CRS for a layer, with the implication not just of the CRS, but also of the gridset that will be used by the MapML viewer:

      This portion builds on top of the work done months ago to support astronomical CRSs, which allows GeoServer to support multiple CRS authorities.

      The MapML preview links are now using the new MapML output format, while the old dedicated REST controller has been removed. This allows for better integration of the MapML format in the GeoServer ecosystem. The MapML viewer has also been updated to the latest version:

      Thanks to Joseph Miller and Andrea Aime (GeoSolutions) for this work, and Natural Resources Canada for sponsoring it.

      Community Module Updates

      Much of the new activity in GeoServer starts as a community module. We’d like to remind you that these modules are not yet supported, and invite you to join the effort by participating in their development, as well as testing them and providing feedback.

      Raster attribute Table community module

      Developed as part of GEOS-11175, the Raster Attribute Table community module uses the GDAL Raster Attribute Table (RAT) to provide a way to associate attribute information for individual pixel values within the raster, to create styles as well as to provide a richer GetFeatureInfo output.

      For more information see the user guide.

      We’d like to thank Andrea Aime (GeoSolutions) for the development and NOAA for sponsoring.

      Graticules for WMS maps

      The graticules community module, developed as part of GEOS-11216, provides a datastore generating graticules for WMS maps, along with a rendering transformation that can be used to label them. The module can be used to draw a graticule in WMS maps, as well as to download them as part of WFS (or in combination with the WPS download module).

      We’d like to thank Ian Turton for development and GeoSolutions for sponsoring the work.

      GeoServer monitor Kafka storage

      The monitoring Kafka storage module, developed as part of GEOS-11150, allows storing the requests captured by the monitoring extension into a Kafka topic.

      We’d like to thank Simon Hofer for sharing his work with the community. To learn more about the module, how to install and use it, see the user-guide.

      JWT Headers

      The JWT headers module has been developed as part of GEOS-11317.

      The module is a new authentication filter that can read JWT Headers, as well as general JSON payloads and simple strings, to identify a user, as well as to extract their roles. The combination of Apache mod_auth_openidc with geoserver-jwt-headers-plugin provides an alternative to using the geoserver-sec-oauth2-openid-connect-plugin plugin.

      We’d like to thank David Blasby (GeoCat) for this work on this module.

    • sur Free and Open Source GIS Ramblings: Trajectools 2.0 released ?

      Publié: 24 February 2024, 8:26pm CET

      It’s my pleasure to share with you that Trajectools 2.0 just landed in the official QGIS Plugin Repository.

      This is the first version without the “experimental” flag. If you look at the plugin release history, you will see that the previous release was from 2020. That’s quite a while ago and a lot has happened since, including the development of MovingPandas.

      Let’s have a look what’s new!

      The old “Trajectories from point layer”, “Add heading to points”, and “Add speed (m/s) to points” algorithms have been superseded by the new “Create trajectories” algorithm which automatically computes speeds and headings when creating the trajectory outputs.

      “Day trajectories from point layer” is covered by the new “Split trajectories at time intervals” which supports splitting by hour, day, month, and year.

      “Clip trajectories by extent” still exists but, additionally, we can now also “Clip trajectories by polygon layer”

      There are two new event extraction algorithms to “Extract OD points” and “Extract OD points”, as well as the related “Split trajectories at stops”. Additionally, we can also “Split trajectories at observation gaps”.

      Trajectory outputs, by default, come as a pair of a point layer and a line layer. Depending on your use case, you can use both or pick just one of them. By default, the line layer is styled with a gradient line that makes it easy to see the movement direction:

      while the default point layer style shows the movement speed:

      How to use Trajectools

      Trajectools 2.0 is powered by MovingPandas. You will need to install MovingPandas in your QGIS Python environment. I recommend installing both QGIS and MovingPandas from conda-forge:

      (base) conda create -n qgis -c conda-forge python=3.9 
(base) conda activate qgis
(qgis) mamba install -c conda-forge qgis movingpandas

      The plugin download includes small trajectory sample datasets so you can get started immediately.

      Outlook

      There is still some work to do to reach feature parity with MovingPandas. Stay tuned for more trajectory algorithms, including but not limited to down-sampling, smoothing, and outlier cleaning.

      I’m also reviewing other existing QGIS plugins to see how they can complement each other. If you know a plugin I should look into, please leave a note in the comments.

    • sur QGIS España: Publicación del libro Introducción a los Sistemas de Información Geográfica con QGIS

      Publié: 22 February 2024, 9:00pm CET
      Publicada la Segunda Edición del Libro “Introducción a los Sistemas de Información Geográfica con QGIS” de Federico Gazaba

      Una pregunta recurrente en redes sociales es ¿Dónde puedo encontrar un manual para aprender a usar QGIS? o ¿Cómo puedo iniciarme en el uso de los Sistemas de Información Geográfica (SIG)? Hace aproximadamente 3 años Federico Gazaba publicaba la pimera versión de su libro “Introducción a los Sistemas de Información Geográfica con QGIS” un manual que en su momento fue de referencia obligada para las personas usuarias de QGIS en habla hispana pero que con el paso del tiempo había quedado desactualizado debido a la aparición de nuevas versiones de QGIS.

      Recientemente el autor nos comentaba que se estaba preparando una actualización de libro y no nos ha hecho esperar mucho, el 22 de Febrero nos anunciaba en el canal de Telegram de QGIS en español que la versión 2.0 había sido publicada: _“Hola amigos #geoinquietos !. Lo prometido es deuda, les traigo la versión 2.0 de mi libro libre “Introducción a los Sistemas de Información Geográfica con QGIS”. Esta versión actualiza los contenidos de la versión anterior a QGIS 3.34 Prizren.".

      Este libro es otro ejemplo que demuestra que los proyectos de software libre y open source permiten compartir y colaborar en este tipo de iniciativas donde podemos participar de forma activa y generar grandes sinergias en sus aplicaciones y desarrollos en beneficio, tanto de las comunidades que las desarrollan como las que las usan.

      Federico Gazaba es profesor de Matemáticas y Técnico Maestro Mayor de Obras y actualmente es docente en el Instituto de Formación Docente y Técnica 122 “Presidente Illia” de Pergamino (Provincia de Buenos Aires, Argentina) y Director de Sistemas de Información Georreferenciada de la Municipalidad de Pergamino. Desde el año de 2013 es usuario de QGIS y es un entusiasta del las tecnologías libres y de los datos espaciales abiertos. La creación del manual nace de la necesidad de impartir cursos de QGIS a sus colegas de municipalidad y es el resultado de la sistematización de esas enseñanzas. Desde 2016, de forma ininterrumpida, imparte cursos introductorios a los SIG para diferentes instituciones.

    • sur Geo-BIM for the Built Environment

      Publié: 22 February 2024, 11:13am CET par Simon Chester

      OGC holds three Member Meetings each year – one each in Europe, the Americas, and Asia Pacific – where OGC’s Standards Working Groups (SWGs), Domain Working Groups (DWGs), Members, and other geospatial experts meet to progress Standards, provide feedback on initiatives being run by the OGC Collaborative Solutions and Innovation (COSI) Program, hear about the latest happenings at OGC, network with the leaders of the geospatial community, and see what’s coming next. The meetings are open to the public, though there are some closed sessions, and provide a great way to start to get to know – and get involved with – the OGC Community.

      The next OGC Member Meeting, OGC’s 128th, will be held at TU Delft on March 25-28, 2024. Fitting for TU Delft and the Netherlands, the theme of the meeting will be ‘Geo-BIM For the Built Environment.’ Meeting sponsorship is generously provided by TU Delft and Geonovum, with support from GeoCAT and digiGO. In the lead up to the event, Geonovum produced a short video highlighting what to expect in Delft.

      “In many respects, the Netherlands is the world leader in the use of advanced integration of building data and detailed urban mapping, as well as the use of Open Standards and Open APIs to interface with those data to provide citizen services,” commented Scott Simmons, OGC’s Chief Standards Officer. 

      “More specifically, TU Delft is a world-leading research institute in Geo-BIM integration, while Geonovum, another meeting sponsor, has done so much to promote the effective use of Open Standards in government & e-government, including documenting proof that Open Standards make things work better, faster, and cheaper.”

      Under the theme, the OGC Member Meeting will include several sessions related to the built environment and the integration of Geospatial and Building Information Models (BIM). Such sessions will include: a Geo-BIM Summit that non-members are encouraged to attend; a Built Environment Joint Session; and a Land Administration Special Session. 

      On top of these, there will be a meeting of the OGC Europe Forum, sessions on Geospatial Reporting Indicators, Observational Data, the ‘Today’s Innovations, Tomorrow’s Technologies’ Future Directions Session, networking opportunities, and the usual host of OGC Working Group meetings on topics ranging from APIs to agriculture, and the sea-floor to space. Most sessions are open to the public, with special encouragement for non-OGC-members to attend the Geo-BIM Summit and any of the Domain Working Group meetings. As always, the opening session will consist of presentations from local organizations that showcase the world-leading geospatial technologies seen in The Netherlands.

      Dr. Rune Floberghagen, Head of the Science, Applications and Climate Department in the Directorate for Earth Observation Programmes, ESA, was one of the local experts that presented at the opening session of the 125th Member Meeting in Frascati, Italy. Geo-BIM Summit

      The Geo-BIM Summit will run on Wednesday afternoon and will focus on the integration of geographic data and Building Information Models (BIM).

      “In the Building Information Modeling (BIM) world, geographical data about the environment of the construction is becoming increasingly important,” said Prof. Dr. Jantien Stoter, Chair of the OGC 3D Information Management DWG, and part of the organizing committee for the Geo-BIM session. “Similarly, in the Geospatial domain, the need for detailed information about buildings is also growing. There are many initiatives to develop solutions that better facilitate this integration, including projects that realize this integration for a specific use case; automated conversion of data between the two domains; methods to georeference BIM files in a standardized and straightforward way; and profiles for standards that establish the integration for specific use-cases. The Geo-BIM session will present such initiatives in order to address the question of “what more is needed to improve the integration?” This will further shape the OGC & buildingSMART Road Map on integration of both domains, and contribute to the best practices currently under development.”

      Built Environment Joint Session

      Two sessions on the Built Environment will run on Wednesday morning. The first is entitled “The Future of Land Infra” and will discuss what more we need to do in the standardization of built infrastructure data, in terms of updating, improving or adding to the OGC Standards Portfolio, and will include input from several OGC activities: the Integrated Digital Built Environment (IDBE) subcommittee, LandAdmin DWG, Model for Underground Data Definition and Integration (MUDDI) SWG; and the Geotech Interoperability Experiment, as well as the wider OGC Collaborative Solutions and Innovation (COSI) Program.

      The next session is entitled “What Urban Digital Twins mean to OGC” and will focus on the wider work that OGC is doing in the space and how the Digital Twins DWG can help harmonize it. The session will also include a cross-working-group discussion on the in-progress OGC Urban Digital Twins Position Paper, as well as a presentation by Binyu Lei, researcher at the Urban Analytics Lab at the National University of Singapore, entitled “Humans as Sensors in Urban Digital Twins.”

      Attendees at the 123rd Member Meeting in Madrid, Spain. Land Admin Special Session

      Following the opening session and keynotes on Monday is a Land Admin special session run by the OGC Land Administration (Land Admin) DWG.

      “Worldwide, effective, and efficient land administration is an ongoing concern, inhibiting economic growth and property tenure,” commented Eva-Maria Unger, co-chair of the OGC Land Admin DWG. “Only a limited number of countries globally have a mature land information system.”

      The Land Admin Special Session will also be the first meeting of the soon-to-be-formed OGC Land Administration Domain Model (LADM) SWG.

      “This is a fairly significant session as we’re going to use it to kick off an effort to create an encoding Standard for Land Administration data that’s globally relevant,” said Scott Simmons. “It’s great to be holding it in Delft because Kadaster, the Netherlands’ Cadaster, Land Registry and Mapping Agency, is one of the world leaders in providing expertise on use of Land Administration and Land Administration modernization across not just Europe but for developing nations around the world. So it’s an opportunity to bring together their expertise along with representatives from all levels of sophistication of land management around the world.”

      Peter van Oosterom continued: “The new SWG will work on the Land Administration Domain Model (LADM) Implementation Standard in OGC, which will be included as part 6 of the existing ISO 19152 series of Standards. This sounds modest, but is actually a big step forward. The LADM Standards today are only Conceptual Models, which means that countries implementing them have to find their own solutions for developing their country file, technical encodings, code list values, processes/workflows, etc. 

      “An open LADM Implementation Standard will not only reduce implementation costs by providing free, proven technical encodings, but would also enable solution vendors to provide commercial off-the-shelf software that works across multiple countries/jurisdictions, rather than having to adapt it to each unique approach.”

      Networking, social, and other sessions

      In addition to these sessions, the 128th OGC Member Meeting will also see meetings of over 50 different working groups or committees covering almost the full breadth of geospatial applications and domains, as well as several social and networking events.

      Registration remains open, as do sponsorship opportunities. Non-members are encouraged to attend. To see the full agenda, visit ogcmeet.org.

      As well as the host of technical content and informative presentations, OGC Member Meetings also include networking events, such as the Wednesday night dinner.
