sur pycsw Team: Using keywords from a thesaurus as queryables
Publié: 18 September 2024, 8:59pm CEST
Using keywords from a thesaurus as queryablesA common convention in catalogues is the use of keywords from a dedicated thesaurus. The assignment of these keywords can then later be used to filter or query the catalogue by these terms. To achieve this use case in pycsw, some configuration needs to be tailored. This blog post indicates the changes needed for this scenario.
For this example we’ll use a keyword from the INSPIRE Themes thesaurus. We will define a new queryable
inspiretheme
, which will be populated with the relevant keyword (if present).You can repeat these steps for any other thesaurus.
Extra database columnExtend the records table in the database with an extra field for the selected thesaurus. This is usually a manual operation on the database.
Add parameter to pycswALTER TABLE records ADD inspiretheme VARCHAR(255);
In
pycsw/core/config.py
the newly created database column can be registered to pycsw.
Add column to mapping'pycsw:InspireTheme': 'inspiretheme',
etc/mappings.py
links the pycsw parameter to the columnname in the table.
Define parameter as queryable'pycsw:InspireTheme': 'inspiretheme',
Which of the parameters are queryable is defined in
pycsw/core/repository.py
.
Add parameter to record results?'inspiretheme': self.dataset.inspiretheme,
Keywords are already published in records, so there is generally no need to extend the record with the new parameter. If needed you can do so in
Populate the parameter from record importspycsw/ogc/api/records.py
(Line 1150).We have 2 options here, either manage the population of the column within the database as part of an insert trigger on the
record.themes
field. Alternatively updatepycsw/core/metadata.py
so the column is populated when records are imported.For the second option consider the following code. For each of the keyword blocks, it tries to match the thesaurus title or uri and, if matched, adds the keywords to the new parameter.
Add parameter to OGC API - Records facets_set(context, recobj, 'pycsw:InspireTheme', ", ".join( [", ".join(k.name for k in t.keywords if k.name not in [None,'']) for t in md_identification.keywords if ( hasattr(t,'thesaurus') and t.thesaurus not in [None,''] and (( 'title' in t.thesaurus and t.thesaurus['title'] not in [None,''] and t.thesaurus['title'] in ['GEMET - INSPIRE themes, version 1.0','GEMET Themes, version 2.3'] ) or ( 'uri' in t.thesaurus and t.thesaurus['uri'] not in [None,''] and t.thesaurus['uri'] == 'http://inspire.ec.europa.eu/theme')))]))
Facets enable to further limit search results. Keywords from thesauri are very useful to add as facet. Add the paremeter to
default.yml
.facets: - type - inspiretheme

sur XYCarto: Cartographic Aotearoa
Publié: 17 August 2024, 3:38am CEST
I try hard to keep this blog about basic open source processing in GIS. I don’t spend much time talking about my cartographic work, since I like put it up in the gallery and try to let it speak for itself. Further, 90% of my cartographic products involve processing data before it ever gets to visualization, therefore, I see more value in demonstrating the basic processing and hopefully inspire folks to do their own thing once their data is in place.
If you might indulge me; however, I’d love to toot my own horn as they say and do a write up on my acceptance to the Atlas of Design this year and the honor to do a brief interview with Radio New Zealand (RNZ) about the map.
I know it is a bit cheeky to put up recognition of one’s own work, but this map was the culmination of several years of iterations, heaps of footwork getting it known, and a number of rejections along the way. I’m just so excited to finally get it out there to a wider audience.
Since this is primarily an open source blog about GIS, and that several have asked me about my tech stack I’ll share a portion of it here. If you want to get a feel of some of my blending techniques, you can see some past blogs where I wrote this up.
As I mentioned above, that vast majority of my cartography is in data prep and making data easier to work in visualization projects. I have a fairly simple tech stack for data prep.
- QGIS – Base map layout. My method is most often to develop the base image here, but do all the post processing for legends, supporting text, graphics, etc in specialized layout software. QGIS is amazing at handling large file types, blending, and making repeatable color palettes. Doing work at a national and world scale is often without issue.
- GDAL – Most used in the stack for prepping large scale raster data. Used more than anything else in GDAL for my vis work is gdalwarp, gdal_translate, gdaladdo, gdalbuildvrt, and gdaldem [hillshade, slope]. These are often used in bash scripts to repeat processes allowing me to easily develop multiple resolutions, scales, and resamples.
- GeoPandas – Used for vectors and primarily for my cleaning to get lighter GPKG files, automating redundant processes like clips, simplification, and table manipulation. It is an amazing tool I use a lot in development too.
- Python/Bash – Used for controlling all the automation and processing. Depending on the complexity of the task at hand, I will bounce between the two. Bash is really great at multi-core processing and can save enormous amounts of time in redundant processes.
- Colorhexa /Gpick – Palette development. Gpick is incredibly helpful in sampling imagery to find a color value you like. You can bring these values into Colorhexa and start to develop gradients and divergent values all the while keeping within your tone. There are many other sites that will help you do this, I just happen to enjoy this one.
- Docker – An unlikely item in a cartographic stack, but Docker has proved invaluable to me by allowing me to run multiple versions of QGIS and GDAL without wrecking my machine. I have a basic QGIS/Docker example here.
For those out there who have supported me on this journey and even those who lurk in the shadows, I cannot thank you enough for reading, liking, and sending me messages letting me know you are out there and find some of this useful. It helps more than you know and motivates me to continue to move forward. Also, tell all your friends!

sur QGIS Blog: Reports from the winning grant proposals 2023
Publié: 16 August 2024, 4:18pm CEST
With the QGIS Grant Programme 2023, we were able to support six proposals (four in the first round and two in the second round) that are aimed to improve the QGIS project, including software, infrastructure, and documentation. The following reports summarize the work performed in the first four proposals:
- QGIS Bug Tracker cleanup (#266) – Report
We have identified and closed ~291 tickets, among them:- 162 bugreports and feature requests which were already fixed or implemented
- 29 bugreports and feature requests which are invalid (data issues, wrong use of functionality, etc)
- 57 duplicate bugreports and feature requests
- 5 won’t fix bugreports
- 5 bugreports were converted to feature requests
- 33 tickets were closed (does not contain steps to reproduce, test data and no feedback was provided within several month)
- Additionally we ensured that all tickets has correct tags assigned to to make them easier to find.
- Porting to C++ and harmonization of Processing algorithms (#271) – Report
The QGIS Porting to C++ and Harmonisation of Processing Algorithms grant is now complete.- Existing Processing algorithms Voronoi Polygons and Delaunay Triangulation have been ported to C++ and now use GEOS instead of the unmaintained Python module.
- Two algorithms for generating XYZ tiles (directory and MBTiles variants) have been ported to C++ using a safer and cleaner multi-threading approach.
- The Align Rasters tool, which was not exposed to Processing, has been removed and a new Processing algorithm with the same functionality has been added.
- The existing Raster Calculator algorithm has been ported to C++. The algorithm now has two variants: a toolbox version that works the same way as before, and a modeler version that uses the same approach to input naming as the GDAL raster calculator.
- Add vertical CRS handling to QGIS (#267) – Report
- As of QGIS 3.34, QGIS can now create and handle vertical and compound CRSes.
- In QGIS 3.34 coordinate transforms were reworked so that they function correctly with vertical transformation, if both the source and destination CRS have vertical components.
- In QGIS 3.36 the coordinate reference selection widgets were updated to offer choices of 2d only, compound, or vertical only CRSes.
- In version 3.38, we introduced a new setting for QGIS projects, for their vertical reference system. Users can control this through project properties, and it’s accessible via PyQGIS and via associated expression variables (eg @project_vertical_crs) for use in print layouts.
- Similarly, in 3.38 we introduced the API support for map layers to have a vertical CRS. (This was not exposed to users in 3.38 though)
- In QGIS 3.40 so far we have exposed the vertical CRS setting for vector layers to users (via the layer properties dialog), allowing users to specify the associated vertical CRS for these layers. The vertical CRS is respected in elevation profile plots, in Identify tool results, and in 3D Map views (assuming the 3D map is created with an associated vertical CRS).
- There is an open pull-request for 3.40 to expose the vertical CRS for point cloud layers in a similar way, with the vertical CRS being respected in elevation profiles, identify tool results, and 3D map views
- We have open pull requests for 3.40 to show layer vertical CRS information in the layer properties “information” pages, and add expression variables at the layer scope (eg @layer_vertical_crs).
- Improve test result handling on QGIS CI (#268) – Report
Any tests which fail a rendering comparison will write a descriptive comment to the PR. The comment details which render tests failed, where they are in the code, and includes some helpful pointers to downloading the full test report and the QGIS developer documentation. We also implemented lots of improvements in running the tests locally and how the render test reports are generated and presented to developers.
Thank you to everyone who participated and made this round of grants a great success and thank you to all our sustaining members and donors who make this initiative possible!

On July 17 I went out for a 30 mile run and had to bail at mile 20. I took some time off from trail running and have been chugging on an elliptical trainer at my gym. Yesterday I tried some running on the bike path behind my house and couldn't even go a mile without excruciating pain. I'm calling it, my season is over. The last time I had serious Achilles tendonitis like this was at the end of my ultimate frisbee career 20 years ago. It took 4 months before I could run without pain. I'm going to keep going to the gym, ice and rest, see some specialists, and get ready for 2025.

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 OGC Approves Model for Underground Data Definition and Integration as Official Standard
Publié: 8 August 2024, 3:00pm CEST par Simon Chester
The Open Geospatial Consortium (OGC) is excited to announce that the OGC Membership has approved version 1.0 of the OGC Model for Underground Data Definition and Integration (MUDDI) Part 1: Conceptual Model for adoption as an official OGC Standard. MUDDI serves as a framework to make datasets that utilize different information for underground objects interoperable, exchangeable, and more easily manageable.
MUDDI represents real-world objects found underground. It was designed as a common basis to create implementations that make different types of subsurface data – such as those relating to utilities, transport infrastructure, soils, ground water, or environmental parameters – interoperable in support of a variety of use cases and in different jurisdictions and user communities. The case for better subsurface data and an explanation of the usefulness of the MUDDI data model is made in this MUDDI For Everyone Guide.
Certainly, a key focus application domain, and one of the main motivations for creating MUDDI, is utilities and the protection of utilities infrastructure. Indeed, OGC’s MUDDI Model was successfully used in pilot testing for the National Underground Asset Register (NUAR), a program led by the UK Government’s Geospatial Commission. More information on NUAR can be found here.
MUDDI aims to be comprehensive and provides sufficient level of detail to address many different application use cases, such as:
- Routine street excavations;
- Emergency response;
- Utility maintenance programs;
- Large scale construction projects;
- Disaster planning;
- Disaster response;
- Environmental interactions with infrastructure;
- Climate Change mitigation; or
- Smart Cities programs.
The MUDDI Conceptual Model provides the implementation community with the flexibility to tailor the implementations to specific requirements in a local, regional, or national context. The standardization targets are specific MUDDI implementations in one or more encodings such as GML (Geographic Markup Language), SFS (Simple Features SQL), Geopackage or JSON-FG encodings that are expected to be standards in future parts of the MUDDI standards family. Both GML and JSON-FG are supported by the OGC API – Features Standard. SFS is supported by a number of database systems.
MUDDI consists of a core of mandatory classes describing built infrastructure networks (such as utility networks) together with a number of optional feature classes, properties, and relationships related to the natural and built underground environment. The creation of implementations targeted to defined use cases and user communities also allows the extension of the concepts provided in MUDDI.
The early work for crafting this OGC Standard was undertaken in the OGC Underground Infrastructure Concept Study, sponsored by Ordnance Survey, Singapore Land Authority, and The Fund for the City of New York – Center for Geospatial Innovation.
The Concept Study was followed by the Underground Infrastructure Pilot and MUDDI ETL-Plugfest workshop, as well as close collaboration with early implementers of MUDDI, such as the UK Geospatial Commission. Several implementations of MUDDI were thoroughly tested in the OGC Open Standards Code Sprint in October/November 2023. The results are described in the OGC 2023 Open Standards Code Sprint Summary Engineering Report and a blog post entitled Going underground: developing and testing an international standard for subsurface data, which describes the experiences and lessons learned from the Geospatial Commission’s attendance at the Code Sprint.
Version 1.0 of the MUDDI Conceptual Model Standard is the outcome of those initiatives, as well as the work and dedication of the MUDDI Standards Working Group, which led the development of the Standard, including:
- Editors:
- Alan Leidner, New York City Geospatial Information System and Mapping Organization (GISMO)
- Carsten Roensdorf, Ordnance Survey
- Neil Brammall, Geospatial Commission, UK Government
- Liesbeth Rombouts, Athumi
- Joshua Lieberman
- Andrew Hughes, British Geological Survey, United Kingdom Research and Innovation
- Contributors:
- Dean Hintz, Safe Software
- Allan Jamieson, Ordnance Survey
- Chris Popplestone, Ordnance Survey
OGC Members interested in staying up to date on the progress of this Standard, or contributing to its development, are encouraged to join the MUDDI Standards Working Group via the OGC Portal. Non-OGC members who would like to know more about participating in this SWG are encouraged to contact the OGC Standards Program.
As with any OGC standard, the open MUDDI Part 1: Conceptual Model Standard is free to download and implement. Interested parties can view and download the standard from OGC’s Model for Underground Data Definition and Integration (MUDDI) Standard Page.

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 OGCBeing 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.

sur GeoServer Team: Using Binary Comparison Operators in GeoServer Filters
Publié: 3 August 2024, 2:00am CEST
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 | X )
Binary Comparison Operators in GeoServer FiltersIn 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.
IntroductionFiltering 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 languagesData 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 LanguageThe 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 LanguageCommon 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 operatorsThese 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.
PropertyIsEqualToPropertyIsNotEqualTo 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 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
PropertyIsLessThan<PropertyIsNotEqualTo>
filter to retrieve all features where theSTATE_NAME
attribute, is not equal toDelaware
.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 theSTATE_FIPS
attribute is less than18
. The query only retrieves theSTATE_NAME
andLAND_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.

sur Jorge Sanz: Elastic Volunteering Time Off
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.
I know I haven’t updated this site in a while, I’ll write one soon! ?

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.
Initial 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 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:
- These platforms often use such resources to track users as they move around the Internet, which we want to avoid as much as possible.
- 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:
- The application itself,
- the user manual and
- 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 workWe 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 outDo 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.
ConclusionWe 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

sur SourcePole: Adding external WMS to the QGIS Cloud Web Map
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. -
