    • sur Paul Ramsey: WKB EMPTY

      Publié: 3 February 2025, 5:00pm CET

      I have been watching the codification of spatial data types into GeoParquet and now GeoIceberg with some interest, since the work is near and dear to my heart.

      Writing a disk serialization for PostGIS is basically an act of format standardization – albeit a standard with only one consumer – and many of the same issues that the Parquet and Iceberg implementations are thinking about are ones I dealt with too.

      Here is an easy one: if you are going to use well-known binary for your serialiation (as GeoPackage, and GeoParquet do) you have to wrestle with the fact that the ISO/OGC standard for WKB does not describe a standard way to represent empty geometries.

      Empty

      Empty geometries come up frequently in the OGC/ISO standards, and they are simple to generate in real operations – just subtract a big thing from a small thing.

      SELECT ST_AsText(ST_Difference(
	'POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))',
	'POLYGON((-1 -1, 3 -1, 3 3, -1 3, -1 -1))'
	))

      If you have a data set and are running operations on it, eventually you will generate some empties.

      Which means your software needs to know how to store and transmit them.

      Which means you need to know how to encode them in WKB.

      And the standard is no help.

      But I am!

      WKB Commonalities

      All WKB geometries start with 1-byte “byte order flag” followed by a 4-byte “geometry type”.

      enum wkbByteOrder  {
    wkbXDR = 0, // Big Endian
    wkbNDR = 1  // Little Endian
};

      The byte order flag signals which “byte order” all the other numbers will be encoded with. Most modern hardware uses “least significant byte first” (aka “little endian”) ordering, so usually the value will be “1”, but readers must expect to occasionally get “big endian” encoded data.

      enum wkbGeometryType {
    wkbPoint = 1,
    wkbLineString = 2,
    wkbPolygon = 3,
    wkbMultiPoint = 4,
    wkbMultiLineString = 5,
    wkbMultiPolygon = 6,
    wkbGeometryCollection = 7
};

      The type number is an integer from 1 to 7, in the indicated byte order.

      Collections

      Collections are easy! GeometryCollection, MultiPolygon, MultiLineString and MultiPoint all have a WKB structure like this:

      wkbCollection {
    byte    byteOrder;
    uint32  wkbType;
    uint32  numWkbSubGeometries;
    WKBGeometry wkbSubGeometries[numWkbSubGeometries];
}

      The way to signal an empty collection is to set its numGeometries value to zero.

      So for example, a MULTIPOLYGON EMPTY would look like this (all examples in little endian, spaces added between elements for legibility, using hex encoding).

      01 06000000 00000000

      The elements are:

      • The byte order flag
      • The geometry type (6 == MultiPolygon)
      • The number of sub-geometries (zero)
      Polygons and LineStrings

      The Polygon and LineString types are also very easy, because after their type number they both have a count of sub-objects (rings in the case of Polygon, points in the case of LineString) which can be set to zero to indicate an empty geometry.

      For a LineString:

      01 02000000 00000000

      For a Polygon:

      01 03000000 00000000

      It is possible to create a Polygon made up of a non-zero number of empty linear rings. Is this construction empty? Probably. Should you make one of them? Probably not, since POLYGON EMPTY describes the case much more simply.

      Points

      Saving the best for last!

      One of the strange blind spots of the ISO/OGC standards is the WKB Point. There is an standard text representation for an empty point, POINT EMPTY. But there nowhere in the standard a description of a WKB empty point, and the WKB structure of a point doesn’t really leave any place to hide one.

      WKBPoint {
    byte    byteOrder;
    uint32  wkbType; // 1
    double x;
    double y;
};

      After the standard byte order flag and type number, the serialization goes directly into the coordinates. There’s no place to put in a zero.

      In PostGIS we established our own add-on to the WKB standard, so we could successfully round-trip a POINT EMPTY through WKB – empty points are to be represented as a point with all coordinates set to the IEEE NaN value.

      Here is a little-endian empty point.

      01 01000000 000000000000F87F 000000000000F87F

      And a big-endian one.

      00 00000001 7FF8000000000000 7FF8000000000000

      Most open source implementations of WKB have converged on this standardization of POINT EMPTY. The most common alternate behaviour is to convert POINT EMPTY object, which are not representable, into MULTIPOINT EMPTY objects, which are. This might be confusing (an empty point would round-trip back to something with a completely different type number).

      In general, empty geometries create a lot of “angels dancing on the head of a pin” cases for functions that otherwise have very deterministic results.

      • “What is the distance in meters between a point and an empty polygon?” Zero? Infinity? NULL? NaN?
      • “What geometry type is the interesection of an empty polygon and empty line?” Do I care? I do if I am writing a database system and have to provide an answer.

      Over time the PostGIS project collated our intuitions and implementations in this wiki page of empty geometry handling rules.

      The trouble with empty handling is that there are simultaneously a million different combinations of possibilities, and extremely low numbers of people actually exercising that code line. So it’s a massive time suck. We have basically been handling them on an “as needed” basis, as people open tickets on them.

      Other Databases
      • SQL Server changes POINT EMPTY to MULTIPOINT EMPTY when generating WKB. 
        SELECT Geometry::STGeomFromText('POINT EMPTY',4326).STAsBinary()

      This release addresses security vulnerabilities and is recommended.

      • CVE-2024-38524 Moderate

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

      File System Sandbox Isolation

      A file system sandbox is used to limit access for GeoServer Administrators and Workspace Administrators to specified file folders.

      • A system sandbox is established using GEOSERVER_FILESYSTEM_SANDBOX application property, and applies to the entire application, limiting GeoServer administrators to the <sandbox> folder, and individual workspace administrators into isolated <sandbox>/<workspace> folders.

      • A regular sandbox can be configured from the Security > Data screen, and is used to limit individual workspace administrators into <sandbox>/<workspace> folders to avoid accessing each others files.

      Thanks to Andrea (GeoSolutions) for this important improvement at the bequest of Munich RE.

      Rendering Points as a Heatmap in GeoServer


      I was assigned the task of rendering a points layer as a heatmap on GeoServer. The client provided a QGIS style that they wanted replicated using an SLD (Styled Layer Descriptor). Initially, they attempted to export the QGIS style directly as an SLD and upload it to GeoServer. However, this approach failed because QGIS generated the heatmap SLD as:


      <?xml version="1.0" encoding="UTF-8"?><StyledLayerDescriptor xmlns="http://www.opengis.net/sld" xsi:schemaLocation="http://www.opengis.net/sld [schemas.opengis.net] xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.1.0" xmlns:ogc="http://www.opengis.net/ogc" xmlns:se="http://www.opengis.net/se">  <NamedLayer>    <se:Name>Current_Layer</se:Name>    <UserStyle>      <se:Name>Current_style</se:Name>      <se:FeatureTypeStyle>        <!--FeatureRenderer heatmapRenderer not implemented yet-->      </se:FeatureTypeStyle>    </UserStyle>  </NamedLayer></StyledLayerDescriptor>


      The main issue was the line:

      <!--FeatureRenderer heatmapRenderer not implemented yet-->

      , indicating that the style was essentially saved as blank or non-renderable. This was simply how the style was exported from QGIS.


      The first step in addressing the request was to visit the GeoServer Styling Manual and see if there was any example documentation that could help. There was an explanation of how to generate a heatmap style in the Rendering Transformations' Heatmap Generation documentation as well as an example of a heatmap SLD.


      Using the example from the documentation as a basis, I made a few adjustments to ensure the style met the client’s requirements. Here is what the initial heatmap style looked like:


      <?xml version="1.0" encoding="ISO-8859-1"?><StyledLayerDescriptor version="1.0.0"    xsi:schemaLocation="http://www.opengis.net/sld StyledLayerDescriptor.xsd"    xmlns="http://www.opengis.net/sld"    xmlns:ogc="http://www.opengis.net/ogc"    xmlns:xlink="http://www.w3.org/1999/xlink"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">  <NamedLayer>    <Name>Heatmap Style</Name>    <UserStyle>      <Title>Heatmap Style</Title>      <Abstract></Abstract>      <FeatureTypeStyle>        <Transformation>          <ogc:Function name="vec:Heatmap">            <ogc:Function name="parameter">              <ogc:Literal>data</ogc:Literal>            </ogc:Function>            <ogc:Function name="parameter">              <ogc:Literal>weightAttr</ogc:Literal>              <ogc:Literal>geometry</ogc:Literal>            </ogc:Function>            <ogc:Function name="parameter">              <ogc:Literal>radiusPixels</ogc:Literal>              <ogc:Literal>75</ogc:Literal> <!-- Spread of heatmap around points, set a number below 100 to reduce spread of heatmap -->            </ogc:Function>            <ogc:Function name="parameter">              <ogc:Literal>pixelsPerCell</ogc:Literal>              <ogc:Literal>5</ogc:Literal> <!-- Set a small number here to generate a higher resolution heatmap -->            </ogc:Function>            <ogc:Function name="parameter">              <ogc:Literal>outputBBOX</ogc:Literal>              <ogc:Function name="env">                <ogc:Literal>wms_bbox</ogc:Literal>              </ogc:Function>            </ogc:Function>            <ogc:Function name="parameter">              <ogc:Literal>outputWidth</ogc:Literal>              <ogc:Function name="env">                <ogc:Literal>wms_width</ogc:Literal>              </ogc:Function>            </ogc:Function>            <ogc:Function name="parameter">              <ogc:Literal>outputHeight</ogc:Literal>              <ogc:Function name="env">                <ogc:Literal>wms_height</ogc:Literal>              </ogc:Function>            </ogc:Function>          </ogc:Function>        </Transformation>        <Rule>          <RasterSymbolizer>            <Geometry>              <ogc:PropertyName>geometry</ogc:PropertyName>            </Geometry>            <Opacity>0.5</Opacity>            <ColorMap type="ramp"> <!-- The quantity specifies the percentage of the data range on which to change the colour -->              <ColorMapEntry color="#FFFFFF" quantity="0" label="" opacity="0"/> <!-- This is needed to have empty areas around the heatmap 'islands' -->              <ColorMapEntry color="#4444FF" quantity=".1" label=""/>              <ColorMapEntry color="#00FFAE" quantity=".3" label=""/>              <ColorMapEntry color="#FF0000" quantity=".5" label="" />              <ColorMapEntry color="#FFAE00" quantity=".75" label=""/>              <ColorMapEntry color="#FFFF00" quantity="1.0" label="" />            </ColorMap>          </RasterSymbolizer>        </Rule>      </FeatureTypeStyle>    </UserStyle>  </NamedLayer></StyledLayerDescriptor>


      Inline comments were added to the SLD to help the client understand which lines they could modify if needed.


      The primary adjustments made to the example style are as follows:


      - Setting the `weightAttr` as `geometry` so that specified input attribute is the geometry of the various points.

      - Adjusting the `radiusPixels` and the `pixelsPerCell` values.

      - Adding additional stops in the colour ramp.

      - Changing the hexcodes of the colours in the colour ramp to be the same as the example heatmap.


      While generating the heatmap style, an issue frequently occurred with GeoServer’s built-in style previewer, which did not display the style accurately. As a result, I had to check the results on the front-end map after every change. This limitation is evident in the screenshot below, where the GeoServer preview lacks a proper front-end to display the styled dummy data, making it appear different from how it would look on an actual map.



      The generated heatmap looked like this when rendered correctly (this is dummy data and not the actual data):



      The client was pleased with the heatmap but later requested additional functionality: displaying the relative counts of the various heatmap surfaces. This prompted me to research whether anyone had implemented something similar that I could use as a reference. After an extensive search yielded no results, I decided to experiment and create a custom SLD to meet the client’s requirements.


      I had previously been shown and used the Point Stacker logic in GeoServer to do clustered symbol displays so I used this as my base logic. The whole logic behind the clustered labelling display didn't need to be complex. All the labels would be the same size, and font, and they just needed to display a relative count.


      Given these criteria, I modified my existing Point Stacker logic to be simplified and it looked like this:


          <FeatureTypeStyle>      <Transformation>        <ogc:Function name="gs:PointStacker">          <ogc:Function name="parameter">            <ogc:Literal>data</ogc:Literal>          </ogc:Function>          <ogc:Function name="parameter">            <ogc:Literal>cellSize</ogc:Literal>            <ogc:Literal>20</ogc:Literal>          </ogc:Function>          <ogc:Function name="parameter">            <ogc:Literal>outputBBOX</ogc:Literal>            <ogc:Function name="env">           <ogc:Literal>wms_bbox</ogc:Literal>            </ogc:Function>          </ogc:Function>          <ogc:Function name="parameter">            <ogc:Literal>outputWidth</ogc:Literal>            <ogc:Function name="env">           <ogc:Literal>wms_width</ogc:Literal>            </ogc:Function>          </ogc:Function>          <ogc:Function name="parameter">            <ogc:Literal>outputHeight</ogc:Literal>            <ogc:Function name="env">              <ogc:Literal>wms_height</ogc:Literal>            </ogc:Function>          </ogc:Function>        </ogc:Function>      </Transformation>     <Rule>        <Name>Clusters</Name>        <Title>Clusters</Title>        <ogc:Filter>          <ogc:PropertyIsGreaterThanOrEqualTo>            <ogc:PropertyName>count</ogc:PropertyName>            <ogc:Literal>5</ogc:Literal>          </ogc:PropertyIsGreaterThanOrEqualTo>        </ogc:Filter>        <TextSymbolizer>          <Label>            <ogc:PropertyName>count</ogc:PropertyName>          </Label>          <Font>            <CssParameter name="font-family">Arial</CssParameter>            <CssParameter name="font-size">10</CssParameter>            <CssParameter name="font-weight">bold</CssParameter>          </Font>          <LabelPlacement>            <PointPlacement>              <AnchorPoint>                <AnchorPointX>0</AnchorPointX>                <AnchorPointY>0</AnchorPointY>              </AnchorPoint>            </PointPlacement>          </LabelPlacement>          <Halo>             <Radius>0.4</Radius>             <Fill>               <CssParameter name="fill">#000000</CssParameter>               <CssParameter name="fill-opacity">1</CssParameter>             </Fill>          </Halo>          <Fill>            <CssParameter name="fill">#FFFFFF</CssParameter>            <CssParameter name="fill-opacity">1.0</CssParameter>          </Fill>        </TextSymbolizer>      </Rule>    </FeatureTypeStyle>


      There is only one clustering rule as having different sized circles symbolizing different sized clusters was not needed. The `cellSize` was set to 20 map units so that all points within a grid cell of 20x20 map units get clustered together. The `count` property was set to be greater than or equal to 5, as during the creation of the style, it became apparent that labelling all of the clusters with fewer than 5 points overcrowded the map visually and did not add any more information.


      The next step was combining the logic for the heatmap and the labelled clusters. After multiple failed attempts, I found that I couldn't combine the two logics into one `FeatureTypeStyle` and needed two separate `FeatureTypeStyle` groups. From there I then played around with the ordering of the `FeatureTypeStyle` logic and learnt that the heatmap style needed to come first in the SLD.


      All the attempts led to this style:

      This style renders the points as a heatmap using the `geometry` attribute for weighting and then displays labels for clusters of points that are larger than 5. It looks like this (Again, this is dummy data and not the actual data):



      The style is functional and has been approved by the client. However, I would like to revisit the labelling logic to better align it with the heatmap styling. Specifically, I aim to have the labels correspond to the colour breaks in the heatmap rather than relying on a separate clustering logic.

    • sur Jackie Ng: Announcing: mapguide-react-layout 0.14.10 and MapGuide Maestro 6.0m13

      Publié: 15 January 2025, 3:21pm CET

      We start the new year with a double-header release of:

      • MapGuide Maestro 6.0m13
      • mapguide-react-layout 0.14.10
      What prompted these new releases other than (it's long overdue)?
      Namely, it is to do with a notification I received about the coming deprecation (and eventual shutdown) of the epsg.io service that both pieces of software use to do proj4 projection lookups for any given EPSG code. This service will shutdown in Feburary (next month) and transition over to the MapTiler coordinates API. This new API requires an API key to use their services.
      In the context of these 2 projects, the API key requirement introduces too much friction.
      • If I take up the offer to use MapTiler, I have to register and bake my API key into both Maestro and mapguide-react-layout and am now responsible for API usage/monitoring under this key from users I have no control over. Last thing I want to deal with is bug reports from users because, let's say for example: proj4 lookup is broken because the API is no longer accessible for my API key due to quota exceeded. I just don't want to deal with such a scenario.
      • Which means the alternative is to change the code to the extent that users can "bring their own API key", taking such API key usage/monitoring concerns out of my hands. This too is also too much hassle. I just want to do EPSG code to proj4 lookups nothing more nothing less!
      If I was building a bespoke/custom mapping application for a client with EPSG > proj4 lookup functionality, then this API key requirement would not have been an issue, but this is not the case here.
      So in light of these concerns, instead of moving to MapTiler coordinates. Instead I have opted to use spatialreference.org to do EPSG -> proj4 lookups. No API keys are required there.
      So since this was the main driver for needing to put out new releases of MapGuide Maestro and mapguide-react-layout, we might as well take this opportunity to lump in some other fixes and minor changes, which are detailed below.mapguide-react-layout changes(reworked) Stamen and (new) StadiaMaps supportStamen tiled layer support was broken for some time since it was taken over by Stadia Maps. I had already taken care of this in the VSCode map preview extension which had the same problem. But for mapguide-react-layout, the fix was a bit different due to it not using the latest version of OpenLayers and it is too much work right now to update to the latest OpenLayers in mapguide-react-layout.
      So what was done for mapguide-react-layout instead is to create these Stamen tile layers as XYZ layers  instead of using the (now broken for that OL release) Stamen tile source. This works because Stamen tiles are ultimately tilesets using the XYZ web mercator scheme. The only other changes is that a Stadia Maps API key is required. So if your appdef defines one or more Stamen tile layers and you didn't specify an API key, you'll get the same startup warning you get when you have Bing Maps layers and didn't specify a Bing Maps API key

      But if you do provide a Stadia Maps API key, you'll get the Stamen layers you've seen before.

      Since a Stadia Maps API key is now required, we've also added support for other tilesets provided by Stadia Maps, like:
      Alidade Smooth

      Alidade Smooth Dark

      Alidade Satellite

      Outdoors

      So if you are loading your mapguide-react-layout viewer from a Flexible Layout document, where do you need to specify this new Stadia Maps API key?
      That's where the new release of MapGuide Maestro comes in to help!MapGuide Maestro ChangesStamen Maps (changed) and Stadia Maps (new) supportThe Fusion Editor has reworked Stamen Maps support and added support for Stadia Maps

      You'll notice that Stamen and Stadia Maps have 2 variants for every layer.
      • A specialized version
      • An XYZ layer variant ("... as XYZ")
      What is the deal with this?
      This was done so that if you are still authoring Flexible Layouts for Fusion instead of mapguide-react-layout, you can still view Stamen and Stadia Maps layers in Fusion through the existing XYZ layer support that is available in Fusion as demonstrated in the screenshot below, using the Stadia Maps alidade_smooth_dark tileset + API key.

      So depending on the context:
      If you are authoring a Flexible Layout for Fusion, choose the "... as XYZ" version and enter the Stadia Maps API key when prompted.
      Otherwise, if you are authoring a Flexible Layout for mapguide-react-layout, choose the specialized version and enter the Stadia Maps API key in the provided field

      This release of mapguide-react-layout will read the Stadia Maps API key from this new setting in the Flexible Layout when initializing with Stamen and Stadia Maps tile layers.
      Using spatialreference.org for EPSG > proj4 lookupsAs stated above, the projection management dialog of the Fusion Editor now uses spatialreference.org for resolving proj4 strings from EPSG codes

      Other changes
      • WMS Feature Source Editor: Improved the responsiveness and usability of the Advanced Configuration Dialog

    • sur OPENGIS.ch: Visualizing Ideas: From circles to planets to story arcs

      Publié: 14 January 2025, 6:00am CET

      My first day at OPENGIS.ch back in September wasn’t what you usually expect when starting at a new workplace. Instead of diving head first into some complex code repository or reading up on company policies, I found myself scribbling lines and circles onto paper.

      The OPENGIS.ch team was meeting in Bern at Puzzle ITC / We Are Cube for a workshop on visualizing ideas, hosted by Mayra and Jürgen from We Are Cube. For a few hours, a room full of slightly unsure, but mostly intrigued geo ninjas armed with pencils and paper discovered a new way to express their ideas through simple visuals.

      Hard at work during the workshop Getting Started: Persuading the «I-Can’t-Draw-For-My-Life» Crowd

      Entering the meeting room, some felt slightly threatened by the pencils on the table, but we were quickly assured that no one was expected to become the next Picasso – just to visualize ideas. Easy, right?

      Visualizations help us understand, remember, and process ideas better than text or numbers can. Our brains are wired to process images far quicker than text. Being able to sketch ideas is a great skill, so let’s do it!

      But for some of us, artistic expression is limited to drawing UML diagrams, and even that can be outsourced to code (see this nifty little tool called Mermaid). So, when it came time to draw our favorite animals as a warm-up, some people were a bit out of their comfort zone. But we soon learned that there are many neat tricks and strategies to make visualizing ideas easier.

      The Basics: Shapes, Containers, Arrows, Expressions

      After getting over the stress of drawing animals, it was time to get into the basics. Jürgen explained that everything can be visualized using just a handful of simple shapes: circles, squares, triangles, and lines.

      Basic shapes and lines

      By adding a few details to these shapes, we can visualize many different objects without getting lost in the complexity of reality. And suddenly, a circle can be a hole in the paper, a plate or planet earth.

      Evolution of a circle from ball to hole in the paper, planet and plate

      To then visualize even more complex ideas, only three basic elements are needed – containers (like rectangles or circles), arrows, and facial expressions. Containers represent the things we care about (whether that’s a person, an object, or an idea). Arrows help us show the relationships or flow between them. And facial expressions, well, they capture emotion.

      By using these basic elements we build complex ideas – no high-level artistic skill required!

      The Story Arc: Put your idea into a story

      Now that we were a bit more comfortable with expressing ourselves on paper, we were introduced to the Story Arc. It’s a framework that helps structure a narrative visually. Whether you’re presenting a project, brainstorming a new product, or explaining a complex process, having a clear story structure makes everything easier to understand and remember.

      So the last task of the day was to invent a story and visualize it. With nothing more than some simple circles, squiggly lines and lots of imagination, we were able to convey our stories with ease. The results were some catchy tales about empty phone batteries, juggling demanding job tasks or flying to the moon to solve a customer problem.

      Story arc of geo ninjas solving customer problems by going to the moon; surely a sci-fi story better than the new Dune movie. Conclusion: The power of visualizing Ideas

      Turns out, visualizing ideas isn’t just for artists! Whether it’s brainstorming a new product or explaining a complex concept, simple visual tools can make ideas clearer and more memorable.

      A light bulb moment for all participants

      So, the next time you’re staring at a blank whiteboard or trying to figure out the best way to pitch an idea, just remember: grab a pencil, draw a circle, and let your imagination go wild. 

      Thanks, Mayra and Jürgen from We Are Cube – you’ve taught us that even non-artists can visualize ideas, and it’s all just a handful of simple shapes away!

    • sur Nick Bearman: FOSS4G 2024 - Belém, Brazil

      Publié: 13 January 2025, 1:00am CET

      I was very lucky to be able to attend FOSS4G 2024, in Belém, Brazil on 2nd - 8th December 2024. Belém is a fantastic city, and due to host COP30 in November 2025, with lots of construction on going. FOSS4G has a wonderful community and a great variety of talks - have a look at the agenda to see the different topics under discussion.

      Tri-lingual welcome, in Portugese, Spanish and English at FOSS4G 2024

      The first two days were workshops, and I attended XYZ Cloud MAPPing 101 presented by Dennis Bauszus, and Community Drone Mapping by Ivan Buendi?a Gayton. In some ways I find the workshops the most useful element of the conference because it gives you time to dig in to a specific piece of software and learn some new skills, something I am quite poor at doing during my usual ‘day job’! I learnt some new useful skills in both workshops. Dennis has also shared the XYZ Mapping workshop materials if you have more discipline than me(!) and can work through it on your own:

      The Drone workshop was also fascinating, and Ivan did a great job of both teaching us how to fly a drone (easier than I thought) and how to help local communities leverage the power of drones (& wider GIS skills) for their own benefit.

      The main conference itself was in the Hanger Convention Centre and it was a great international conference. The laid back approach of FOSS4G always creates a lovely atmosphere and it was a great opportunity to get to know new people in the FOSS4G world, and catch up with people I have met at previous events. Community is one of the key things that I love about this group, with people very willing to help each other out. Uber is a key method of transportation in Brazil, and with a number of the evening social events in the city centre, we usually clubbed together at the hotel reception for an Uber to get us there, and back afterwards!

      The variety of talks was incredible, with fascinating applications of FOSS4G tools, discussions on the interaction of academia and FOSS4G and personal reflections on people’s FOSS4G journeys. I particularly Kim Durante’s talk on FAIR Principles for Geospatial Data Curation which might have some very useful ideas for a project I am working on at the moment, and Veronica Andreo’s talk, From field biology to the GRASS GIS board - an open source journey about how she got involved in the GRASS GIS project.

      I met one lady from Brazil and this was her first international, English speaking conference. She was really enjoying herself and it was a great introduction to the FOSS4G community for her.

      One thing that came across to me was the variety of open source projects, and how some projects seem to be doing very similar things. Two examples that come to mind are QField and Mergin Maps, both of which allow users to collect data in a QGIS project in the field on their phone, and process that data back in the office. Another pair would be QGIS and GRASS GIS, both arguably great quality Desktop GIS tools, and there are many other examples too.

      Initially I wondered why there were so many similar tools like this, when it might make more sense to combine effort and focus on one tool, rather than splitting our effort over two? However after a bit of reflection I discovered a) that often two similar tools have differences that make them more useful to different audiences. For example, QField is a more flexible field data collection tool, and Mergin Maps is easier to get up and running with. Also, b) having multiple tools reflects the market approach of encouraging development and innovation, with the best tool ‘winning’. In this context winning is not by having the highest revenues or the highest profits, but by having communities of users and developers. If a project doesn’t have a good group of users and/or a good group of developers interested in keeping the project up to date, then gradually it will fall out of use. I was not expecting to see an example of a capitalist based market in the open source community, but here it is!

      I also had the opportunity to met Katja Haferkorn, who is the coordinator for FOSSGIS e.V. FOSSGIS e.V. is the OSGeo Local Chapter for German-speaking countries - D-A-CH, i.e. Germany, Austria and the german speaking part of Switzerland. FOSSGIS e.V. is also the German local chapter for OpenStreetMap. FOSSGIS e.V. is quite unique in that they are a local chapter who has a paid coordinator - Katja - and it was fascinating to hear her experiences. As OSGeo:UK Chair, one of the questions I asked her was about diversity within Local Chapters, and OSGeo as a whole. This is an issue for them as well and it is a aspect of membership that has been challenging the whole community for a while. Katja has written a great blog post about the conference. It is in German, but Google Translate does a reasonable job of translating it into English.

      Working at the Code Sprint, thanks to Felipe Barros for the photo

      The last two days of the conference was the Code Sprint. This is a chance to meet people working on different open source GIS projects and learn how to contribute to different elements of the projects. I had a great chat with Silvina Meritano and Andrés Duhour about using R as a GIS. Silvina was keen to develop her mapping skills in R, and Andrés had already developed an R package (which he presented at the conference: osmlanduseR) and spent a bit of time learning about and contributing to the new tmap library examples. Tmap version 4 is coming out (blog post coming soon!) and I needed to updated my material for this new version. I also spent some time looking at the Las Calles De Las Mujeres project, which looks at the proportion of streets named after women (rather than men) in a range of Spanish speaking countries. Silvina and I had a go at creating a version in R that could automate some more of the process to apply this to different cities in English speaking countries.

      The internet connection at the code sprint was a little variable, so we had some challenges and had to resort to using the “sneaker net” occasionally - using a USB stick to transfer data between us! Fortunately we never had to resort to playing truco - a card game played in Argentina when the internet doesn’t work and you have nothing else to do!

      Thanks very much to everyone involved in organising the conference. Many more photos are on Flickr. The conference was a fantastic experience, and if you ever have the opportunity to go to a FOSS4G conference, anywhere, do take it!

    • sur GeoServer Team: GeoServer 2025 Roadmap

      Publié: 13 January 2025, 1:00am CET

      Happy new year and welcome to 2025 from the GeoServer team!

      Last year we started something different for our project - sharing our 2024 roadmap plans with our community and asking for resources (participation and funding) to accomplish some challenging goals. We would like to provide an update for 2025 and a few words on our experience in 2024.

      The GeoServer project is supported and maintained thanks to the hard work of volunteers and the backing of public institutions and companies providing professional support.

      GeoServer was started in 2001 by a non-profit technology incubator. Subsequent years has seen the project supported by larger companies with investors and venture capital. This support is no longer available - and without this cushion we must rely on our community to play a greater role in the success of the project.

      We are seeking a healthy balance in 2025 and are asking for support in the following areas:

      • Maintenance: The GeoServer team uses extensive automation, quality assurance tools, and policy of dropping modules to “right size” the project to match developer resources.

        However maintenance costs for software markedly increased in 2024 as did time devoted to security vulnerabilities. This causes the components used by GeoServer to be updated more frequently, and with greater urgency.

        ?? Community members can answer questions on geoserver-user forum, reproduce issues as they are reported, and verify fixes.

        ?? Developers are encouraged to get started by reviewing pull-requests to learn what is needed, and then move on to fixing issues.

      • Security Vulnerabilities: GeoServer works with an established a coordinated vulnerability disclosure policy, with clear guidelines for individuals to particpate based on trust, similar to how committers are managed. Our 2024 experience with CVE-2024-36401 highlights the importance of this activity for our community and service providers.

        ?? Trusted volunteers can help mind geoserver-security email list, and help reproduce vulnerabilities as they are reported. We also seek developer capacity and funding to address confirmed vulnerabilities.

      • Releases: Regular release and community testing is a key success factor for open source projects and is an important priority for GeoServer. Peter has done a great job updating the release instructions, and many of the tasks are automated, making this activity far easier for new volunteers.

        ?? Developers and Service Providers are asked to make time available to to assist with the release process.

        Asking our community to test release candidates ahead of each major release has been discontinued due to lack of response. The GeoServer team operates with a time-boxed release model so it is predictable when testing will be expected.

        ?? Community members and Service Providers are asked to help test nightly builds ahead of major releases in March and April.

      • Testing: Testing of new functionality and technology updates is an important quality assurance activity We have had some success asking downstream projects directly to test when facing technical-challenges in 2023.

        ?? We anticipate extensive testing will be required for GeoServer 3 and ask everyone to plan some time to test out nightly builds with your own data and infrastructure during the course of this activity.

      • Sponsorship: In 2023 we made a deliberate effort to “get over being shy” and ask for financial support, setting up a sponsorship page, and listing sponsors on our home page.

        The response has not been in keeping with the operational costs of our project and we seek ideas on input on an appropriate approach.

        ?? We ask for your financial assistance in 2025 (see bottom of page for recommendations).

      The above priorities of maintenance, testing and sponsorship represent the normal operations of an open-source project. This post is provided as a reminder, and a call to action for our community.

      2025 Roadmap Planning CITE Certification

      Our CITE Certification was lost some years ago, due to vandalism of a build server, and we would like to see certification restored.

      OGC CITE Certification is important for two reasons:

      • Provides a source of black-box testing ensuring that each GeoServer release behaves as intended.
      • Provides a logo and visibility for the project helping to promote the use of open standards.

      Recent progress on this activity:

      • As part of a Camptocamp organized OGCAPI - Features sprint Gabriel was able setup a GitHub workflow restoring the use of CITE testing for black-box testing of GeoServer. Gabriel focused on OGC API - Features certification but found WMS 1.1 and WCS 1.1 tests would also pass out of the box, providing a setup for running the tests in each new pull request.
      • Andrea made further progress certifying the output produced by GeoServer, restoring the WMS 1.3, WFS 1.0 and WFS 1.1 tests, as well as upgrading the test engine to the latest production release. In addition, CITE tests that weren’t run in the past have been added, like WFS 2.0 and GeoTIFF, while other new tests are in progress, like WCS 2.0, WMTS 1.0 and GeoPackage.

      GeoServer 3

      GeoServer 3 is being developed to address crucial challenges and ensure that GeoServer remains a reliable and secure platform for the future.

      Staying up-to-date with the latest technology is no longer optional — it’s essential. Starting with spring-framework-6, each update requiring several others to occur at the same time.

      GeoServer 3 Updates

      Our community is responding to this challenge but needs your support to be successful:

      • Brad and David have made considerable progress on Wicket UI updates over the course of 2024, and with Steve’s effort on Content Security Policy compliance (CSP headers are enabled by default in newer versions of Wicket).

      • Andreas Watermeyer (ITS Digital Solutions) has been steadily working on Spring Security 5.8 update and corresponding OAuth2 Secuirty Module replacements.

      • Consortium of Camptocamp, GeoSolutions and GeoCat have responded to our roadmap challenge with a bold GeoServer 3 Crowdfunding. The crowd funding is presently in phase one collecting pledges, when goal is reached phase two will collect funds and start development.

        Check out the crowdfunding page for details, faq, including overview of project plan.

        GeoServer 3 Milestones

      ?? Pledge support for GeoServer 3 Crowdfunding using email or form.

      ?? Developers please reach out on the developer forum if you have capacity to work on this activity.

      ?? Testers GeoServer 3 will need testing with your data and environment over the course of development.

      [https:]]

      OSGeo welcomes pgRouting to its growing ecosystem of projects.

      OSGeo is pleased to announce that pgRouting has graduated from incubation and is now a full-fledged OSGeo project.

      pgRouting is an open-source extension in the PostGIS / PostgreSQL geospatial database, providing geospatial routing functionality.

      Graduating incubation includes fulfilling requirements for open community operation, a responsible project governance model, code provenance, and general good project operation. Graduation is the OSGeo seal of approval for a project and gives potential users and the community at large an added confidence in the viability and safety of the project.

      The pgRouitng Steering Committee collectively recognizes this as a big progressive step for the project.

      pgRouting has been an active contributor and participant to various open source initiatives inside and outside OSGeo such as FOSS4G, OSGeo Code Sprints, OGC Code Sprints, Joint OSGeo-OGC-ASF (Apache Software Foundation) Code Sprints, and Google Summer of Code.

      The pgRouitng PSC says, “We are excited about the future of the project within the OSGeo’s project ecosystem. We have been working to have a community of developers for the project sustainability. It is our honor to be an OSGeo project”.

      The pgRouting PSC would like to thank our mentor, Angelos Tzotsos, and the OSGeo Incubation Committee for their assistance during this Incubator process.

      Congratulations to the pgRouting community!

      About pgRouting

      pgRouting extends the PostGIS / PostgreSQL geospatial database to provide geospatial routing functionality. It is written in C++, C and SQL.

      It is an open source PostgreSQL extension which implements several graph algorithms.

      pgRouting library contains the following features:

      • All Pairs Shortest Path algorithms: Floyd-Warshall and Johnson’s Algorithm
      • Shortest Path and bi-directional algorithms: Dijkstra, A*
      • Graph components, analysis and contraction algorithms.
      • Traveling Sales Person
      • Graph components, analysis and contraction algorithms.
      • Shortest Path with turn restrictions

      pgRouting is able to process geospatial and non geospatial graphs.

      It’s processing extension execute a number of existing graph algorithms based on reliable software and libraries. It is written in such a way that gives the ability to hook a new graph algorithm in a clean way including the connection code to the database.

      The pgRouting functions are standardized in terms of parameter types and names, decreasing the learning curve of a user.

      pgRouting is very flexible with graph data input, in an inner SQL query and output with standardized column names, so you can process almost any kind of graph data stored in the database.
