    • sur Ian Turton's Blog: How to reproject features in QGIS

      Publié: 9 August 2024, 2:00am CEST

      I came across a brilliant thread on Mastodon by Sarah Dal discussing how she worked out what the most remote post box in the UK was. But there was one remark that bothered me, she said that to convert her lat, lon points to OSGB (EPSG:4326 to EPSG:27700 for the nerds) she had to go to the Ordnance Survey site to find some software to do this. Since she already had the points in QGIS this seemed like an unnecessary side quest to me. When I commented that she could have done this in QGIS she said that she always seemed to get it wrong.

      I’m confused by this (and by the many other people who ask questions on gis.stackexchange.com about the same thing) so I’ve put together this video showing how I would do this. Basically, you right click on the layer you want to reproject and select export->Save features as and then just change the drop down box to the projection you need. QGIS will then save the features and add that layer to your project. You shouldn’t see any difference other than the colour of the points will change (as QGIS assigns a new random colour to the new layer).

      And yes, I really should have split the Northern Irish post boxes out into a separate file and projected them to the Irish grid but this is just a demo.

    • sur Public Services on the Map: A Decade of Success

      Publié: 7 August 2024, 10:05pm CEST par Simon Chester

      The Netherlands’ Cadastre, Land Registry, and Mapping Agency (Kadaster) maintains the nation’s register of land and property rights, ships, aircraft, and telecom networks. It’s also responsible for national mapping and the maintenance of the nation’s reference coordinate system and serves as an advisory body on land-use issues and national spatial data infrastructures. In its public service role, Kadaster handles millions of transactions a day.

      Celebrating 10 years: PDOK’s evolution. (click to enlarge)

      PDOK was launched in 2013 to make the Dutch government’s geospatial datasets Findable, Accessible, Interoperable, and Reusable (FAIR) as mandated by the EU’s INSPIRE Directive. OGC Standards have been foundational in ensuring that the country’s Spatial Data Infrastructure (SDI) is scalable, available, and responsive.

      PDOK serves base maps and Earth Observation data for the whole country. It includes the Key Topography Register (Basisregistratie Topografie, BRT), aerial imagery (updated annually at 8 and 25 cm GSD), and the Large Scale Topography Register (Basisregistratie Grootschalige Topografie, BGT). The BGT is a detailed digital base map (between 1:500 and 1:5,000) that depicts building footprints, roads, water bodies, railways lines, agricultural land, and parcel boundaries. PDOK also serves a 3D dataset of buildings and terrain created from topography (BGT), building footprints (from the  Building and Addresses Register or BAG), and height information (from aerial photography).

      When PDOK was launched in 2013, it hosted 40 datasets and handled 580 million server requests annually. Today it hosts 210 datasets and handles 30 billion server requests annually—representing a 5,000% increase in service requests being handled by the platform.

      Examples of PDOK basemaps and imagery. Standards Enabling Success

      The majority of datasets on PDOK are made available using OGC’s popular Web Map Service (WMS) and Web Feature Service (WFS) standards. The BRT is available in three coordinate reference systems (EPSG 28992, EPSG 25831, and EPSG 3857) using the Web Map Tile Service (WMTS) standard. 

      Kadaster is in the process of transitioning to the newer OGC API Standards, including OGC API – Tiles and OGC API – Features. The most frequently used key registers, like the Building and Addresses Register (BAG), the Large Scale Topography Register (BGT), and the Key Topography Register (BRT) are in the process of being migrated to these newer OGC APIs. The focus is on using OGC API – Tiles, specifically Vector Tiles. For query services the OGC API – Features Standard is used. Although Earth Observation data doesn’t currently use the newer APIs, aerial imagery is available through WM(T)S services, stored as OGC Cloud Optimized GeoTiffs (CoG). 3D Building data is encoded as OGC 3D Tiles and served using the OGC API – 3D GeoVolumes standard. 

      The PDOK architecture and OGC Standards. (click to enlarge)

      By using the newer OGC API Standards, Kadaster has found it significantly easier to handle the large volume of data in its national-scale 3D building dataset (which can be used between scales of 1:500 and 1:10,000) providing an unparalleled, high-resolution perspective of the country’s built environment.

      OGC APIs also make it easier to track compute and memory usage on servers, allowing Kadaster to better realize platform scalability and optimize performance.

      PDOK uses the OGC API – 3D GeoVolumes to serve the 3D building dataset. (click to enlarge) A Smooth Transition to OGC APIs

      PDOK processes billions of user requests every month. Transitioning from OGC Web Services Standards to OGC APIs has meant Kadaster is able to efficiently handle the volume of requests it handles today – and can expect to handle in the future. 

      It took Kadaster little over a month to build their implementation of OGC API – Tiles. Following a short learning curve they were able to build out implementations of OGC API – Features and API – 3D GeoVolumes even faster. By making the move to deliver its geospatial tiles and feature data through an API conformant to the OGC API Standards, Kadaster continues to make government data Findable and Accessible. 

      PDOK implements what Kadaster calls the 3G principle—Generic (Generic), Geautomatiseerd (Automated) en Gestandaardiseerd (Standardized). This has led to simplified data processing, the automation of many manual processes, a standardization in services, and high standards in service design and operation – while at the same time remaining infrastructure independent. It has streamlined the adoption of new OGC Standards and made it better able to respond to changing user requirements.

      Kadaster and OGC

      Being an OGC Member allows Kadaster to leverage the collective knowledge of a global network of geospatial experts, while providing Kadaster with opportunities to contribute back to a community driven to use the power of geography and technology to solve problems faced by people and the planet.

      Kadaster has recently contributed to the OGC Community by participating in an OGC Code Sprint. These hybrid online/in-person events give participants the opportunity to work on implementations of new or emerging OGC Standards.

      Through OGC, Kadaster has also shared their experiences and challenges at OGC Member Meetings, contributing to the ongoing evolution of OGC Standards, Collaborative Solutions and Innovation (COSI) Program Initiatives, and, more broadly, advanced the “state of the art” of geospatial technologies.

      The below video provides an overview of PDOK.

The main approach of this startup is providing quality, valid specialized training in the field of geospatial information.

      Binary Comparison Operators in GeoServer Filters

      In this session, we want to talk about the various types of filters, with a particular focus on “Binary comparison operators in GeoServer” comprehensively. If you want to access the complete tutorial, click on the link.

      Introduction

      Filtering allows the selection of features that satisfy a specific set of conditions. Filters can be used in several contexts in GeoServer:

      • In WMS requests, select which features should be displayed on a map
      • In WFS requests, specify the features to be returned
      • In SLD documents, apply different symbolizations to features on a thematic map

      Note. This video was recorded on GeoServer 2.22.4, which is not the most up-to-date version. Currently, versions 2.24.x and 2.25.x are supported. To ensure you have the latest release, please visit this link and avoid using older versions of GeoServer.

      Supported filter languages

      Data filtering in GeoServer follows the OGC Filter Encoding Specification, which provides a standard XML schema for encoding spatial, attribute, and temporal filters in GIS. This allows for customized queries to retrieve specific data from databases and web services while ensuring interoperability among GIS applications. GeoServer supports filters in both Filter Encoding Language and Common Query Language.

      Filter Encoding Language

      The Filter Encoding language, defined by OGC standards, utilizes an XML-based syntax to select specific features, similar to the “WHERE” clause in SQL. A filter consists of a condition formed by Predicate elements and Logical operators, employing comparison and spatial operators to evaluate relationships between feature properties. In this session, we will explore various types of binary comparison operators, while the next sessions will cover spatial operators.

      Common Query Language

      Common Query Language (CQL) is a Text-based language used in GeoServer for constructing filters and queries on geospatial data. It provides flexible and powerful options for filtering and retrieving specific subsets of data from GeoServer layers. In the upcoming sessions, we will dive into a detailed exploration of CQL/ECQL, covering its various operations and practical usage.

      Comparison operators

      These operators are part of Filter Encoding operators and are used in attribute-based queries to filter and retrieve specific features or data, based on their non-spatial attributes. The comparison operators include: binary comparison operators and value comparison operators.

      The binary comparison operators are:

      • PropertyIsEqualTo
      • PropertyIsNotEqualTo
      • PropertyIsLessThan
      • PropertyIsLessThanOrEqualTo
      • PropertyIsGreaterThan
      • PropertyIsGreaterThanOrEqualTo

      These operators contain two filter expressions to be compared. The first operand is often a <PropertyName>, but both operands may be any expression, function or literal value. Binary comparison operator elements may include an optional matchCase attribute, with the true or false value. The default value is true, but the comparisons do not check the case if the attribute has a false value.

      Note. String comparison operators are case-sensitive.

      PropertyIsEqualTo

      PropertyIsNotEqualTo is a common type of filter used in GeoServer, which allows you to retrieve features from a data source based on the values of one or more properties. As an example of using this filter in WFS getFeature request:

      • Navigate to the Demos page, then select Demo requests.
      • From the Request section, select the WFS_getFeature1.0.xml request.
      • The address will be filled in automatically, in the URL section.

      Use the following block codes to replace line 26:

      <PropertyIsEqualTo>
  <PropertyName>STATE_NAME</PropertyName>
  <Literal>Delaware</Literal>
</PropertyIsEqualTo>
      • Now, we will explain some elements:
        • The first fifteen lines include explanations in the form of comments.
        • Line 16 describes the XML version and the GetFeature operation of the WFS service being used.
        • Line 17 specifies the default output format for the WFS service as “gml2.” Additionally, GeoServer supports several other commonly used formats such as “gml3, shapefile, geojson, and csv.”
        • Lines 18 to 23 define the start of the XML request and declare the namespaces used in the request.
        • Line 24 specifies the type name of the feature to be queried. In this case, it requests features of the “topp:states”.
        • Lines 25 to 30 define the filter criteria for the query. On these lines, we use the PropertyIsEqualTo filter, to retrieve all features where the state name attribute is equal to Delaware.

      • Press the Submit button to see the implemented changes.

      • Note. For GeoServer 2.25.2 the Demo Request page has been improved to show response Headers, and provide the option to pretty print XML output.
      PropertyIsNotEqualTo

      PropertyIsNotEqualTo is another common type of filter used in GeoServer, which allows you to retrieve features from a data source based on properties that don’t match a specified value. As an example of using this filter in a WFS getFeature request, use the following block codes to replace lines 26 to 29:

      <PropertyIsNotEqualTo matchCase="false">
  <PropertyName>STATE_NAME</PropertyName>
  <Literal>delAwarE</Literal>
</PropertyIsNotEqualTo>

      Note. The matchCase attribute in WFS_getFeature 1.1 and 2.0 versions, can be set to “false” to specify a case-insensitive comparison.

      Press the Submit button.

      In this example, we used the <PropertyIsNotEqualTo> filter to retrieve all features where the STATE_NAME attribute, is not equal to Delaware.

      PropertyIsLessThan

      The PropertyIsLessThan filter is used to filter features, based on a comparison of a numeric property with a given value. It returns all features where the specified property is less than the specified value.

      An example of using this filter in a WFS getFeature request is:

      outputFormat="shape-zip"
<wfs:Query typeName="topp:states">
    <wfs:PropertyName>topp:STATE_NAME</wfs:PropertyName> 
    <wfs:PropertyName>topp:LAND_KM</wfs:PropertyName>
<ogc:Filter>
  <PropertyIsLessThan>
    <PropertyName>STATE_FIPS</PropertyName>
    <Literal>18</Literal>
  </PropertyIsLessThan>
</ogc:Filter>

      Press the Submit button.

      In this example, we used the <PropertyIsLessThan> filter to get all features in a shapefile format where the value of the STATE_FIPS attribute is less than 18. The query only retrieves the STATE_NAME and LAND_KM fields, instead of all the attributes.

      In this session, we took a brief journey through the various types of filters, with a particular focus on “Binary comparison operators in GeoServer”. If you want to access the complete tutorial, simply click on the link.

      Publié: 23 July 2024, 11:15am CEST

      My employer, Elastic, has a number of philanthropic initiatives but definitely the one I love the most is the Volunteering Time Off (VTO). We are given 40 hours per year from our working hours to contribute to projects and initiatives we care about. Employees have full freedom to choose what they want to do with that time and are encouraged to use it.

      In my case, over this almost 5 years I have to admit I haven’t used all that time every year but I tried to get the most of it. During COVID I did some remote work for a local NGO that works for fair trade, giving them a webinar about Open Source among other things (see update from December 2019 and following months). I also spent a few days working on some admin tasks for the Open Source Geospatial Foundation and I’ve already written here about a couple sessions I did for Cibervoluntarios, training seniors and teens about safe browsing and email.

      Last week I was showcased in the company blog, along with other colleagues, on different projects to contribute to. In my case, last year I joined the mapping efforts after the Morocco Earthquake and took a full day mapping roads and streets of a rural area, as part of the coordinated efforts from the Humanitarian OpenStreetMap team (reported on my October community update). I’m very happy to have this support from my employer to leave things aside when an emergency like this arises, granted there are no other urgent issues at work.

      As a personal call to action, I’d love to get back to Cibervoluntarios activities. This year has been quite busy; let’s see after summer if there’s room for getting out and engaging with them.

    • sur QGIS Blog: Introducing the new QGIS.org website

      Publié: 23 July 2024, 9:00am CEST

      We have a new website!

      We recently launched our new website at QGIS.org. It is a ground-up overhaul and provides a fresh take on the first contact point for existing or potential users wishing to engage with the QGIS project and discover its value proposition.

      A new strategy for QGIS.org websites

      In this blog post, we would like to provide an overview of the goals that we had for building the new QGIS.org website and the bigger picture of how this website update fits into the broader strategy for our website plans for QGIS.

      About two years ago, we started experimenting with building a new QGIS.org website based on Hugo. Hugo, as a technology choice, was less important than was our intent to develop a more modern site that addressed our strategic goals.

      After some ‘in-house’ (i.e. volunteer-based) work to develop an initial version of the site, we received the go-ahead to use QGIS funds for this and put out a call in October 2023 for a company to support our work. This was ultimately won by Kontur.io, who, together with our volunteers, brought the work into high gear.

      Questions to be quickly answered by qgis.orgInitial analysis of the questions and actions to be quickly answered by qgis.org

      Goal 1: Speak to a new audience

      Our primary goal was to speak to a new audience. We are confident that QGIS can compete with all of the commercial vendors providing GIS software. We didn’t convey that well on our old website. We feel that QGIS was too apologetic in how it presented itself. We wanted a website which inspires confidence while addressing the needs of a corporate or organisational decision-maker who is looking at the QGIS project during their GIS software selection process.

      The old website was very focused on the developer and contributor community. Obviously, those aspects are important since, without our fantastic community, the QGIS project would not exist. The messaging around open source is also important. Yet these ideas are secondary to the idea that QGIS is one of the best (if not the best) desktop GIS applications out there on the market – open-source or otherwise. We need to present it in this professional perspective.

      So, the first goal was to change the messaging to focus on QGIS’s value proposition and take a very professional approach to presenting ourselves on the website.

      User group analysisUser group and requirements analysis for the potential qgis.org visitors

      Goal 2: Harmonisation

      The second goal was to start the process of harmonising all of our website properties. QGIS.org, over the years, has built many different web properties. For example, there’s the plugins website, the feed, the changelog, the sustaining members website, the lessons website and the certification website, the new resources hub website, the API documentation, the user documentation, the user manual, the training manual, various other documentation efforts, and more. Some of those are combined in one application, There are also some less well-known resources, like our analytics.qgis.org and another one for plugin analytics. In short, we’ve a lot of resources!

      With so many different web properties, they’ve devolved over time: each has its own look and feel, navigation approach and how you interact with it. Some of them were translated, and some of them were not. We want to harmonise all of these sites so that the user does not notice any change in user experience when they move from one QGIS-related site to another.

      Goal 3: Harmonising deployment

      In the underlying process of these changes, we’re also redeploying all of the websites on new servers, which are more up-to-date and use better security and maintenance practices. Plenty of work is happening in the background to ensure that all of the servers are in a better-maintained state, document how they’re maintained, and so on.

      Goal 4: A hub and spokes

      The objective of the new site design is to allow quick movement between the QGIS auxiliary sites. The QGIS.org site will form a hub that effortlessly takes visitors to whichever QGIS-related site they need to complete the task they are busy with. If you’re moving between these sites, the experience should be seamless. You should not really even be aware that you’re moving between different websites. Other than looking at the URL bar, the user presentation and experience should be harmonious between all of them.

      One way we are planning to achieve this is to have a universal menu bar and footer. You will see that in the new website’s design, there is a menu bar across the top. This menu bar has two levels: the top menu and the second level, where the search bar is.

      The universal menu bar

      In this second row, auxiliary sites will have their own sub-menu whilst keeping the shared top-level menu. So if you, for example, are moving around in plugins and want to review the plugin list or submit a new plugin, all of that navigation will be on the second line where the search bar is currently. Regardless of which subdomain you are on, the top-level menu bar will be the same, allowing you to easily navigate back to the hub or to another subdomain.

      The footer will be unified and shared between all sites, and the cascading style sheets and styling will be unified across all of the QGIS websites.

      In the next phase, we will work to achieve this coherence across all the websites, though we still have a few more tweaks to make to the qgis.org site first.

      Goal 5: DOTDOTW – do one thing, do one thing well

      We plan to break some auxiliary websites apart into separate pieces. So, for example, the changelog management, certification management, sustaining members management, and lessons management are all in one Django app. We will split them into small single-purpose applications using some common UX metaphors so that each is a standalone application that makes it easy for a potential contributor to understand everything the application does. This will also simplify management as we can upgrade each auxiliary site on separate development cycles. We will also finally have semantic URLs, e.g. certification.qgis.org, to take you to the different areas of interest on the site.

      The plugins.qgis.org is also going to be refactored so that it just has plugins and not the resource sharing we’ve added in the last few years. The resource sharing will go into its own subdomain. Similarly, the Planet website will get split into its own website (the planet is a blog aggregator or RSS aggregator) that will be in its own managed instance. Some other components (like the analytics) are difficult to split out like this because they’re linked to the same database. We will try to make sure that those are more discoverable and theme them as much as possible to match the rest of the website experience.

      Goal 7: Encapsulation

      Another goal we had for the QGIS.org makeover was to make the site performant and self-contained. By self-contained, we mean that it should not ‘call’ out to CDN, Google or other platforms for resources like fonts, CSS frameworks, javascript libraries, etc. There were two reasons for this:

      1. These platforms often use such resources to track users as they move around the Internet, which we want to avoid as much as possible.
      2. We want to wholly manage our site, be able to fix any issues independently and generally follow a path of self-determination.

      Our approach also facilitated the creation of a very performant website, as you can see here. We will try to adhere to these principles for the auxiliary site updates we do in the future, too.

      What about translations?

      The question has come up: Why did we not want to translate the new QGIS.org when it was translated before?

      Firstly, we should make it clear that we do not plan to remove translations from the user documentation, the user manual, and so on, where we think they have the most value.

      For the main QGIS.org site, we question whether there is a high value in translating it. Here are some reasons why:

      1. Lingua franca: If you are an IT manager in a non-English-speaking country and you want to evaluate some software, you’re going to run into a product page that presents itself in English – it is the norm for IT procurement to work in English for reviewing software products and so on.

      2. Automation: Automated translations inside browsers are getting better and better. While these translations are still not completely adequate, we think they will be in one or two years’ time.

      3. Translation integrity: Our pursuit of Goal 1 means that we would no longer find it acceptable to have partial website translations. We also need to ensure that the wording and phrasing are consistent with the English messaging. We also have concerns about the QA process regarding trust and review – we want to ensure that any translation truly reflects the meaning and intent of the original content and has not been adjusted during the translation process.

      4. Cohesion: Our most important point is raised if we go back to this idea of cohesion between the different websites like QGIS.org, plugins.qgis.org and so on. As well as having the same styling, we also don’t want to switch between languages as you hop between the sites. We aim to present them all as one site. If we translate QGIS.org and then take you to our auxiliary sites, e.g., plugins.qgis.org, the feed, or certification pages, which are in English only, the experience is jarring.

      So we must either translate everything into all of the same languages, or work in English. Translating everything is a mammoth task for the translators and for us to retrospectively add translation support to each platform. Thus, we prefer the approach of harmonising everything to one language and then focusing our translation efforts on three areas:

      1. The application itself,
      2. the user manual and
      3. the training manuals.

      We can leave the rest of the experience in English and instead focus on harmonising, for now, both in terms of look and feel and the technology used.

      When we consider everything as one big website and what the bigger plan is, it is hopefully clearer why we didn’t think translating the landing page and QGIS.org was the best approach.

      Further funded work

      We hope to use more QGIS funding to support this work in the future. We’re also hoping to work again with Kontur to start moving all these auxiliary sites into their own projects, applying our style guidelines to each. Independently of that, Tim (volunteer), Lova (QGIS funded), and others are already getting started with this process.

      Helping out

      Do you have strong opinions about the website? Contact Tim on the PSC mailing list if you would like to get involved as a volunteer. We would love to hear from designers, word smiths, marketers, information architects, SEO specialists, web developers and those who think they can help us achieve our goals.

      Conclusion

      We hope our goals and process make sense for everybody and that we were able to lay out a clear, logical argument about why we don’t want to translate the new website quite yet. We want to focus on these overarching goals and then return to them later if they are still a priority for people. Everything we have built is Open Source and available at this repo, where you can also find an issue tracker to report issues and share ideas relating to the new website.

      Thanks for reading. Go spatial without compromise ??

      Cheers, Tim, Marco and Anita

      Publié: 23 July 2024, 2:00am CEST
      The use of WMS/WMTS layers in a QGIS Cloud map project can significantly degrade the performance of the map display. I have already discussed how to counter this problem in an earlier post. One of the solutions is to load external WMS as background layers. The problem with this approach, however, is that only one WMS background layer can be loaded at a time. If further WMS layers are to be loaded into the map at the same time, this approach cannot be used.

    • sur GeoServer Team: GeoServer 2024 Q3 Developer Update

      Publié: 22 July 2024, 2:00am CEST

      This is a follow up to 2024 roadmap post outlining development opportunities.

      First of all thanks to developers and organisations that have responded with offers of in-kind contributions. This blog post is assessing current progress and outlines a way forward to complete the Java 17/Jakarta EE/Spring 6 upgrades.

      This post highlights development activities that are available to be worked on today, along with interested developers and commercial support providers available to work on GeoServer roadmap items.

      Spring Framework 6 Tasks

      The key challenge we are building towards is a spring-framework 6 update, ideally by the end of 2024 when the version we use now reaches end-of-life.

      The tasks below are steps towards this goal.

      Wicket 9 upgrade

      Interested Parties:

      • Brad has been doing amazing work with the Wicket 9 upgrade and is in need of assistance.
      • GeoCat has offered to do manual A/B testing when PR is ready for testing.

      Activity:

      Spring Security 5.8 update

      Spring Security 5.8 provides a safe stepping stone ahead of the complete spring-framework 6 upgrade and is an activity that can be worked on immediately.

      Interested parties:

      • Andreas Watermeyer (ITS Digital Solutions) offered to work on this activity in during the initial January call out, and has indicated they are now ready to start.

      Activity:

      Spring Security Core implementation of OAuth2 / OIDC

      The spring-security-oauth client has reached end-of-life and a GeoServer OAuth2 support must be rewritten or migrated as a result.

      There are two paths to migrate to spring-security-core implementation:

      • Option: Migrate the existing community module implementations to spring-security-core in place; with as little loss of functionality as possible. This has the advantage of using existing test coverage to maintain a consistent set of functionality during migration.

      • Option: Setup a community module alongside the existing implementation with the goal of making a full supported etension. This approach has the advantages of allowing organisations the ability to do A/B testing as both the old and new implementation would be available alongside each other. This has the advantage of allowing stakeholders to only fund, implement, test functionality as required without disrupting existing use.

      Security integrations often require infrastructure to develop and test against, which the core GeoServer team does not have access to for automated tests. We would like to see organisations review their security integration requirements and be on hand to support this development activity.

      The initial priority will support for OAuth2 and Open ID Connect (OIDC), parties interested in maintaining support for Google, GeoNode, GitHub are welcome to participate.

      Interested Parties:

      • Andreas Watermeyer (ITS Digital Solutions) offered to work on this activity, or test as needed.
      • GeoCat is interested in this work also, with the goal of bringing the OIDC plugin up to full extension status (if financing is available).

      Activity: not started

      • [GEOS-11272] spring-security-oauth replacement, with spring-security 5.8
      ImageN / JAI Replacement

      The image processing library used by GeoServer has been donated to the open source community under the name ImageN.

      The immediate goal has been to add test cases to this codebase and make an ImageN 1.0 release. Andrea has come up with the amazing idea of integrating with JAI-Ext project immediately, to benefit from the improved operators, and jumpstart test coverage.

      Interested Parties:

      • Jody (GeoCat) is available to support this activity, or take lead if funding is available.
      • Andrea (GeoSolutions) has had a deep dive into the implications for the JAI-EXT project outlining a roadmap for project integration

      We would like to see organisations that depend on GeoServer for earth observation and imagery to step forward with funding for this activity.

      2024 Financial support and sponsorship

      Thus far 2024 has not had a strong enough sponsorship response to support the project goals above. As a point of comparison we established a budget of $15,000 with OSGeo last year to take on an low-level API change that affected several projects.

      This year GeoServer sponsorship has raised between $1,000 and $2,000 which is not enough to plan with or coordinate in-kind contributions offered thus far.

      Jody has worked with the OSGeo board to make adjustments to the sponsorship:

      • Guidance has been provided for appropriate sponsorship levels for individual consultants, small organisation, companies and public institutions of different sizes.
      • There are clear examples of how to sponsor and donate, along with the the perks and publicity associated with financial support
      • GeoServer has a new sponsorship page on our website collecting this information
      • GeoServer now lists sponsors logos on our home page, alongside core contributors.

      We would like to thank everyone who has responded thus far:
