Ian Turton's Blog: How much fun was FOSS4g 2023?
sur Planet OSGeoReview of FOSS4G 2023 IntroductionFOSS4G 2023 was held in Prizren, Kosovo and there were 800+ attendees from 120+ countries. This was a great attendance despite Kosovo not being the easiest place to get to, especially if you were me. I had booked flights to and from Belgrade, Serbia because they were a relatively good times for me (I am missing being only 1 hour from a London airport). It looked like an easy 4 hour drive from the airport to Prizren. Then about a fortnight before the conference Kosovo closed it border to Serbian registered cars! A subsequent check all showed that most of the hire companies wouldn’t let you drive one of their cars over a border (and apparently despite the Serbian Government’s claims they considered Kosovo a separate country). So I fell back on the 9 hour overnight bus trip, which wasn’t as bad as it could have been but did mean I started the conference already somewhat sleep deprived.
Sort of Historical Side NoteWhen I was at school learning Geography all of this area was called Yugoslavia and it was behind an “iron curtain” so we knew little about it and cared even less (it was not on the exam). In history it was covered by the break up of the Ottoman Empire and the meddling of Bismarck as an “honest broker” at the 1878 Congress of Berlin (as I recall he rigged the Balkans in such a way as to start World War I, but history O-Level was a long time ago). So you can already see that there is a long a complex history and geography in the region. It became more complex in the 1990s when Yugoslavia broke up in a series of bloody conflicts, which I remember from the evening news. Kosovo only really came to my attention in 2008 when I was walking through New York with James Macgill and his kids and we saw a large group of cars flying large red flags with double headed eagles on them (and the one thing I retained from my history lessons is the ability to spot a double headed eagle at 200 metres). These were Kosovans celebrating the declaration of independence being proclaimed.
So squabbling about car number plates was pretty peaceful really. Fortunately, for us most of KFOR (the UN/Nato peace keeping force) had gone home, except for some in the Northern predominately Serb areas where they were out keeping the piece over disputed elections for city mayors. This meant we could use their old base as a conference venue, which was great except for the lack of lifts.
Cool talksThis is a list of talks I found particularly interesting or fun and that stuck in my mind long enough to remember for this post. There were lots of great talks that I either failed to see because the room was too full or was too hot for my brain to have taken in the details, so I’m looking forward to the videos coming out so I can refresh my memory later.
- Neiene Boeijen Let’s put it on the map!

gvSIG Team: Optimizando el trabajo con datos en gvSIG Desktop: Tutorial para pasar de shapefile a base de datos H2Spatial.
sur Planet OSGeoSi queréis optimizar vuestro trabajo a la hora de trabajar con información geográfica… no os perdáis este vídeo, sobretodo si manejáis capas de información grandes, con cientos de miles o millones de registros, lo que siempre da problemas de velocidad a la hora de hacer zooms, desplazamientos, etc.
Lo que os vamos a mostrar es cómo cambia de manera exponencial la velocidad de trabajo de tener nuestros datos en un formato como el shapefile a hacerlo con una base de datos espacial. H2 es una base de datos ligera, muy fácil de usar y que en nuestro caso va directamente incluida en gvSIG Desktop, por lo que no requiere ninguna instalación. Se basa en ficheros, por lo que distribuir una base de datos de H2 es tan sencillo como compartir un determinado fichero.
En el ejemplo que se muestra en el vídeo vamos a trabajar con una capa del denominado SIGPAC (una especie de Catastro agrícola) de la provincia de Valencia y que contiene aproximadamente 2 millones de registros.
Hemos decidido no cortar el vídeo para que veáis que lo único que demora es el paso inicial de exportar el shapefile a la base de datos, por lo que podéis ver hasta el minuto 2:20 y luego pasar al minuto 17, donde ya tenemos la misma información en ambos formatos y se realiza la comparativa en sí. Vuestros problemas para manejar volúmenes de datos grandes, sin requerir instalar nada adicional a vuestro SIG de escritorio… ya se han resuelto.

One of them was on the benefits and many pitfalls of putting rasters into a relational database, and the other was about real-time events and pushing data change information out to web clients!
TL;DR: geospatial data tends to be more “visible” to end user clients, so communicating change to multiple clients in real time can be useful for “common operating” situations.

gvSIG Team: Working with Enumerations in gvSIG Online (and gvSIG Mapps)
sur Planet OSGeoAmong the many tools available to gvSIG Online users, there are those related to enumerations. These types of functionalities are extremely useful for data maintenance, as they allow us to define the possible values for a field. They become even more useful when using gvSIG Mapps integrated with gvSIG Online, as when capturing or updating information using the mobile application, these fields will display dropdown menus for easily selecting the corresponding value for each recorded element.
Enumeration lists can be added, modified, or deleted from the administration area of gvSIG Online. We can create a list from scratch or instruct gvSIG Online to automatically generate it based on the unique values available in that field. Interesting, right?
Once an enumeration is created, we can also assign it to other fields in other layers. Even more interesting, isn’t it?
When editing a published layer in a project, these fields will display a dropdown menu with the elements that make up the list, and one of them can be selected to assign it as an attribute of a map element, if it is of type “enumeration,” or multiple elements if it is of type “multiple enumeration.”
And, as we mentioned earlier, in gvSIG Mapps, we would automatically have our dropdown menus ready to facilitate data collection in the field.

OGC Compliance Certification Available for v1.0 of the OGC API – Processes Standard
sur Open Geospatial Consortium (OGC)The Open Geospatial Consortium (OGC) is excited to announce that the Executable Test Suite (ETS) for version 1.0 of the OGC API – Processes – Part 1: Core Standard has been approved by the OGC Membership. Products that implement the Standard and pass the tests in the ETS can now be certified as OGC Compliant.
The OGC API – Processes Standard supports the wrapping of computational tasks into executable processes that can be offered by a server through a Web API and be invoked by a client application. Typically, these processes combine raster, vector, coverage, and/or point cloud data with well-defined algorithms to produce new information. Examples of computational processes that can be supported by implementations of this Standard include vector data analysis, imagery analysis, and various types of Artificial Intelligence (AI) enhanced analysis. To learn more about how the family of OGC API Standards work together to provide modular “building blocks for location” that address both simple and the most complex use-cases, visit ogcapi.org.
Implementers are invited to validate their products using the new test suite, which is available on the OGC validator tool. Testing involves submitting the endpoint of an OGC API – Processes implementation to be assessed. The validator tool sends the appropriate requests to the endpoint of the implementation and then evaluates the responses. These tests typically take only 5-10 minutes to complete. Once a product has passed the tests, the implementer can submit an application to OGC for use of the OGC Compliant trademark on their product.
To support developers with implementation of the standard, GeoLabs ZOO-Project 2.0 and Ecere GNOSIS Map Server 1.0 have been designated as reference implementations of the standard after the software products successfully passed the compliance tests.
The OGC Compliance Program offers a certification process that ensures organizations’ solutions are compliant with OGC Standards. It is a universal credential that allows agencies, industry, and academia to better integrate their solutions. OGC compliance provides confidence that a product will seamlessly integrate with other compliant solutions regardless of the vendor that created them.
More information about the OGC compliance process is available at ogc.org/compliance. Implementers of version 1.0 of the OGC API – Processes – Part 1: Core Standard – or other OGC Standards – are welcomed to validate their products using the OGC validator tool.

gvSIG Team: Trabajar con enumeraciones en gvSIG Online (y gvSIG Mapps)
sur Planet OSGeoEntre las muchas herramientas que los usuarios de gvSIG Online tienen disponibles se encuentran las relacionadas con enumeraciones. Este tipo de funcionalidades son extremadamente útiles para el mantenimiento de los datos, ya que nos permiten definir los valores posibles de un campo. Doblemente útil si utilizamos gvSIG Mapps integrado con gvSIG Online, ya que a la hora de capturar o actualizar información con la aplicación móvil, en esos campos se nos mostrarán desplegables para elegir fácilmente el valor que corresponde a cada elemento relevado.
Los listados de enumeraciones se pueden añadir, modificar o eliminar desde el área de administración de gvSIG Online. Podemos crear un listado desde cero o bien decirle a gvSIG Online que lo genere automáticamente a partir de los valores únicos disponibles en ese campo. ¿Interesante, verdad?.
Una vez creada una enumeración también podemos asignársela a otros campos de otras capas. ¿Más interesante aún, no?
Cuando se inicie la edición de una capa publicada en un proyecto, en estos campos se desplegarán el listado con los elementos que conforman el listado y se podrá seleccionar uno de ellos para asignarlo como atributo de un elemento del mapa,si es del tipo «enumeración», o varios si es de tipo «enumeración múltiple».
Y, como ya hemos comentado, en gvSIG Mapps tendríamos automáticamente nuestros desplegables listos para facilitar la toma de datos en campo. -

Geomatic Blog: Retiring geomaticblog.net
sur Planet OSGeoVicente, Pedro-Juan, and me started this blog in 2006. Back then blogs were the best way to create content and share knowledge. It was the times of RSS, Google Reader, social bookmarking through
del.icio.us
, and pictures onFlickr
. Very different from these days of micro-blogging, quick videos, influencers moving from one platform to another chasing their viewers' attention and money, newsletters under paywalls, etc.We stayed for a few months in a self-hosted Drupal CMS but maintaining it was a pain, so we moved to a managed Wordpress where we lived most of the time. Wordpress offered an excellent balance to get us writing without much hassle, keeping our domain, and very infrequent ads. Finally, last year I migrated the content to Hugo, a static generator, to save some costs, but the decline in writing started in 2018, so it is OK to close this project formally.
I will keep the blog code and content on a GitHub repository at [https:]] where we have posts in Markdown since 2007, and everything is hopefully for ever available in the web archive at [https:]] . I will probably copy my posts to my website.
Needless to say that we are forever grateful to those that encouraged us to write here. I had a lot of fun maintaining the website and writing content for everyone else. We are easy to find on the Internet, so please contact us anytime!

A recap of the 126th OGC Member Meeting, Huntsville, AL, USA
sur Open Geospatial Consortium (OGC)From June 5-9, almost 200 geospatial innovators, influencers, and leaders from across the globe attended OGC’s 126th Member Meeting – with 100 more attending virtually. Hosted by GEOHuntsville at the beautiful Huntsville Botanical Garden in Alabama, USA, meeting attendees spent the week discussing the latest geospatial innovations and hearing how geospatial is transforming organizations and industries across the globe.
The meeting was additionally sponsored by Hexagon, OpenSensorHub (Botts Innovative Research and GeoRobotix), Ethar, Womble Bond Dickinson, and Compass-HSV.
The week saw the usual abundance of Standards Working Group (SWG) and Domain Working Group (DWG) meetings, networking & social events (including a fantastic Sunday pre-meeting gathering at the Signals Museum, hosted by Ethar), two award presentations – a Lifetime Achievement Award as well as the new Community Impact Award – and several special sessions, including a Space Standards ad hoc, an Open Science Summit, a Portrayal Workshop, a Connected Systems track, a Defense and Intelligence Track, and a Climate Workshop.
The full agenda for the 126th OGC Member Meeting is available here. Read on for an overview of the best bits, below.
OGC CEO, Dr. Nadine Alameh (L), OGC CSO, Scott Simmons (M), and Stan Tillman from meeting sponsor, Hexagon. Opening SessionOpening the meetings on Monday morning was David Lucas, the Executive Director of host GEOHuntsville, who welcomed attendees and provided event context. This was followed by a welcome from the City of Huntsville Mayor, Tommy Battle.
Next, we heard from Stan Tillman, of meeting sponsor Hexagon, who provided information on the company with specific information regarding Hexagon Digital Reality capabilities. Dr. Chris Tucker, representing additional meeting sponsors OpenSensorHub participants Botts Innovative Research and GeoRobotix, then highlighted the upcoming session on Tuesday for Connected Systems.
OGC CEO Dr. Nadine Alameh then provided a CEO Welcome and described the value of recent organizational changes in OGC. Prashant Shukle, Chair of the OGC Board of Directors then gave a greeting from the Board and highlighted a commitment by the Board to more actively participate in OGC activities.
OGC CEO, Dr. Nadine Alameh (L), with Patty Mims, Director of Global National Government, EsriNadine’s regular fireside chat followed, this time with Patty Mims, Director of Global National Government, Esri. As has become the trend for these chats, they discussed the motivation for joining the geospatial industry as well as provided advice for others to join and succeed in the community.
Trevor Taylor, Senior Director, Member Success and Development of OGC, welcomed new members and refreshed attendees on the new OGC membership model that’s now in place for new members.
I, Scott Simmons, Chief Standards Officer of OGC, then wrapped up the session by providing some logistics information for the week and describing the process to be followed in the coming weeks-to-months to roll out of the new Technical Committee Policies and Procedures. I also described the new tools in place for submitting presentation requests and special sessions for meetings.
Special SessionsThe Space Standards ad hoc continued the discussion from the 125th Member Meeting concerning where OGC should work in Space Standards, which identified a number of topical areas for Standardization as well as existing Standards covering some portions of those areas. Participants at this session identified areas of focus and proposed a new Domain Working Group (DWG) that will begin the chartering process in the coming weeks. OGC Members can access the presentations and a recording on this page in the OGC Portal.
The Open Science Summit focused on a proposal for a new OGC Pilot project for an Open Science Persistent Demonstrator. NASA, Google, and the European Space Agency (ESA) each presented information on their own platforms. The Summit then followed with an open discussion on which other platforms might exist and what should be included. OGC Members can access the presentations and a recording on this page in the OGC Portal.
Marge Cole, Director, Collaborative Solutions and Innovation Programs, OGC, speaking at the Open Science SummitThe Portrayal Workshop: OGC has been modernizing its Standards for the portrayal of geospatial data. Numerous other communities have dependencies on the OGC Standards portfolio and need to understand the applicability of these newer Standards and how they replace the functionality of legacy Standards. The Portrayal Workshop was organized jointly with the International Cartographic Association (ICA) and was run to develop an OGC Technical Paper for “Standards supporting cartographic best practices.” OGC Members can access the presentations and a recording on this page in the OGC Portal.
The Connected Systems track: OGC has chartered new working groups to update and create a RESTful implementation of sensor-related Standards. The Autonomy, Sensors, Things, Robots, and Observations (ASTRO) Domain Working Group (DWG) investigates requirements and standardization targets and the Connected Systems Standards Working Group (SWG) is building the new Standards. These groups held a full-afternoon track to describe the intent of the Connected Systems API, the relationship of the work to other OGC APIs and the Sensor Web Enablement (SWE) Standards, and to demonstrate how the new Standards work in practice. OGC Members can access the presentations and a recording on this page in the OGC Portal, as well as the Demonstration here.
The Defense and Intelligence Track: The Defense and Intelligence DWG takes a broad look at the use of Standards in defense/intelligence operations as well as the requirements for interoperability that can be solved, in part, by Standards. The DWG held a full-afternoon track to explore the fundamental concepts and thus bring participants to a baseline of understanding. The session also explored where OGC members could contribute to new Standards in imagery & motion imagery as well as Space. OGC Members can access the presentations and a recording on this page in the OGC Portal.
The Climate Workshop: OGC’s Climate Resilience DWG organized a Climate Workshop for Friday where the DWG defined the nature of its mission for resilience as the “ability of a system to compensate for impacts.” The session highlighted numerous initiatives underway in OGC and other organizations, framing them in terms of opportunities for impact. The workshop also expressed a proposed timeline for the next OGC Climate Resilience Pilot. OGC Members can access the presentations and a recording on this page in the OGC Portal.
Today’s Innovation/Tomorrow’s Technology and Future DirectionsThe popular Today’s Innovation/Tomorrow’s Technology and Future Directions session focused on ongoing OGC research and deployment of the nascent OGC Rainbow (borne from the OGC Definitions Server), which represents the state-of-the-art in enabling semantic interoperability.
OGC Rainbow is a web-accessible source of information about things (“Concepts”) that the OGC defines or that communities ask the OGC to host on their behalf. OGC Rainbow comprises several registries linked to common access for both human- and machine-readable representation of the data.
The OGC Definitions Server has long provided Coordinate Reference System (CRS) definitions, terminology definitions used in OGC Standards, and code lists for various domains of interest. As the capability of the OGC Rainbow increases, OGC will be registering requirements from Standards, representation of the OGC Building Blocks, and linkages to other authoritative registries. OGC Rainbow will improve consistency in the geospatial standards community and allow for expedited development of new capabilities.
Dr. Ingo Simonis and Dr. Rob Atkinson of the OGC COSI Program explained the capabilities and use cases of the OGC Rainbow and moderated open discussion amongst participants regarding the use of OGC Rainbow. OGC Members can access the presentations and a recording on this page in the OGC Portal. Stay tuned to the OGC Blog for more on the OGC Rainbow soon.
Dinner & AwardsThe always wonderful Executive Dinner was held on Wednesday night at the U.S. Space & Rocket Center – Davidson Center for Space Exploration, where attendees had the unforgettable experience of dining under an actual Saturn V rocket – one of only three in the world!
Attendees of the Executive Dinner had the unforgettable experience of dining under an actual Saturn V RocketAt the dinner, two awards were presented: Dr. Jeff de La Beaujardiere received the OGC Lifetime Achievement Award; and Natural Resources Canada received the inaugural OGC Community Impact Award.
Dr. Jeff de La Beaujardiere was selected for the Lifetime Achievement award due to his long standing leadership, commitment, and support for the advancement and uptake of standards used for the dissemination of Earth Science information. In the OGC community, Jeff is best known as the Editor of the OGC Web Map Service (WMS) Specification: a joint OGC/ISO Standard that now supports access to millions of datasets worldwide. OGC WMS was the first in the OGC Web Services suite of Standards and is the most downloaded Standard from OGC. But most importantly, the OGC WMS Standard truly revolutionized how geospatial data is shared and accessed over the web. Jeff was also a major contributor to other OGC Standards, including the OGC Web Services Architecture, the OGC Web Map Context, OGC Web Terrain Service, and OGC Web Services Common.
The new OGC Community Impact award highlights the importance of collaboration, volunteering time and energy, advancing technologies and standards, raising awareness, and helping solve critical issues across the geospatial community. Natural Resources Canada exemplifies all of these qualities through their championing of innovation and standards. They consistently go above and beyond as both an OGC Member, and as a member of the wider geospatial community.
My well-deserved congratulations go out to both recipients!

The Important Things session then featured a discussion on how much OGC SWGs should accommodate developer interests and existing applications vs. optimizing their Standards work to meet the Standard requirements. OGC Members then discussed the issue and provided numerous examples of the conflict in current work. OGC Members can read the notes from the session in the Etherpad “Important-Things-2023-06”.
The Closing Plenary, though mostly focused on presentations and voting, also saw several presentations. Carsten Rönsdorf of Ordnance Survey provided a summary of the effectiveness of the model-driven standard authoring that was used for CityGML 3.0 and is now underway with MUDDI. Ali Al’Awaji highlighted the success of recent cooperation between his organization, the General Authority for Survey and Geospatial Information (GASGI) and OGC. The remainder of the session advanced a number of Standards, SWGs, and documents toward vote or publication.

GeoCat: FOSS4G 2023
sur Planet OSGeoWow what an adventure, Jody Garnett here returning from visiting FOSS4G conference and the GeoCat offices.
FOSS4G for the PeopleThe Free and Open Source Software for Geospatial conference was very much a community affair this year. FOSS4G 2023 was a chance to meet and speak with peers from the GeoNetwork and GeoServer projects and connect with companies and the B2B activity.
Indeed GeoCat attended with a booth, and a few things to hand out, and conversation. Our booth was near the speakers, so we would sneak over and turn down the music so we could talk. And we talked a lot – so many nice people! With all the talking I do not beleive I opened my laptop to show off our products once the entire week.
It was a pleasure seeing Jeroen and Florent comfortable on the massive stage providing an 1:250k scale overview of GeoNetwork activities.
I had a good workshop on GeoServer with Ian Turton to start, and some entertaining presentations with Andrea over the course of the week. The GeoServer Feature Frenzy and GeoServer used in fun and interesting ways were real highlights with great audience response.

gvSIG Team: Inventario turístico georreferenciado del Pla de Mallorca adaptado a la Normativa (UNE 178503)
sur Planet OSGeoComo parte de uno de los proyectos que estamos abordando con la Suite gvSIG, la IDE turística de la Mancomunidad del Pla de Mallorca, hemos realizado un inventario turístico en el que se ha partido de datos existentes y se ha realizado labor de toma de datos en campo (con gvSIG Mapps). La novedad de dicho inventario es que es pionero en la adopción de la Norma UNE 178503 para representar las distintas capas de datos georrefenciados.
La UNE 178503:2022 “Semántica aplicada a destinos turísticos inteligentes”, define una semántica base que permite representar la información relevante en la que se conforma el destino turístico (destino turístico, recursos turísticos dentro del destino, experiencias de viaje), asegurando la interoperabilidad de sus plataformas turísticas y de la ciudad y el territorio entre sí y con desarrollos de terceros.
Esta adopción de la Norma ha conllevado un trabajo previo de análisis de datos existentes y de la propia Norma permitiendo, entre otras cosas, identificar posibles términos que no están incluidos en la norma UNE 178503:2022 o campos que no aplican a las características de la Mancomunidad. De este modo se ha conseguido una adopción y adaptación a la realidad particular del destino del Pla de Mallorca que ha acabado reflejado en el modelo de datos de la Infraestructura de Datos Espaciales.
Por tanto, este proyecto ha conllevado llevar la interoperabilidad de datos geográficos turísticos un paso más allá, tanto en servicios de acceso (WMS, WMTS. WFS) como en semántica y modelo de datos.
En breve os contaremos más sobre el proyecto y compartiremos la IDE/Geoportal resultante, donde podréis consultar el inventario. Todo ello desarrollado con gvSIG Online para la publicación de datos, gvSIG Mapps para la toma de datos y gvSIG Desktop para el tratamiento de datos.

Marco Bernasocchi: QField background tracking
sur Planet OSGeoYears ago, the QField community and its users showed their love for their favourite field app by supporting a successful crowdfunding to improve camera handling.
Since then, OPENGIS.ch has continued to lead the development of QField with the regular support of sponsors. We couldn’t be prouder of the progress we have made, with plenty of new features added in every major release. This includes major improvements to positioning including location tracking, integration of external GNSS receivers through not only Bluetooth but TCP/UDP and serial port connections, accuracy indicator and constraints, and most recently sensors reading to list a few.
We are now calling for the community to help further better QField and unlock an important milestone: background location tracking service.
Pledge now Main goal: background location tracking on Android – 25’000€Currently, QField requires users to keep their devices’ screen on and have the app in the foreground to keep track of the device’s positioning location. On mobile devices, this can drain batteries faster than many would want to, in environments where charging options are limited.
This crowdfunding aims at removing this constraint and allow QField – via a background service – to constantly keep tracking location even while the device is suspended (i.e., when the screen is turned off / locked).
To achieve this, a significant amount of work is required as the positioning framework on Android will need to be relocated to a dedicated background service. Recent work we’ve done adding a background service to synchronize captured image attachments in QFieldCloud projects armed us with the assurances that we can achieve our goal while giving us an appreciation of the large amount of work needed.
Some of the benefitsRunning out of battery is the nightmare of most field surveyors. By moving location tracking to a background service, users will be able to improve their battery life considerably and keep focusing on their tasks even if it involves switching to a different app.
Furthermore, while OPENGIS.ch ninjas remain busy squashing reported QField crashes all year long, there will always be unexpected scenarios leading to abrupt app shutdowns, such as third-party apps, systems running out of battery, etc. To address this, the background service framework will also act as a safeguard to avoid location data loss when QField unexpectedly shuts down and offer users means to recover that data upon re-opening QField.
Stretch goal 1: background navigation audio feedback 5’000€The second stretch goal builds onto QField’s nice fly-to-point navigation system. If the QField community meets this threshold, a new background navigation audio feedback informing users in the field of their proximity to their target will be implemented.
The audio feedback will use text-to-speech technology to state the distance to target in meters for a given time or distance interval.
Stretch goal 2: iOS 15’000€The main goal will cover the Android implementation only. Due to being a very low level work we will have to replicate the work for each platform we support. If we reach stretch goal 2 we will also implement this for iOS.
Pledge now:In case you do not see the embedded form you can open it directly here.
Thanks for supporting our crowdfunding and keep an eye on our blog for updates on the status.

gvSIG Team: Geocoder of gvSIG Online. Versatility and power in address searches.
sur Planet OSGeoThe geocoding plugin of gvSIG Online is a powerful and versatile tool that allows us to search for places and locate them on the map. At the user level, its operation is extremely simple. Once the search string is entered, a list of possible candidates is displayed. At the administration level, the most interesting feature is that we can configure and add as many providers/geocoders as we need.
Of course, the plugin offers functionality for both forward geocoding (locating a place based on a search string) and reverse geocoding (finding the address by marking a position on the map).
From the administration panel, in the list of search providers, you can assign a category (to group the results of that provider under a separator) and assign an icon that will mark each of the suggested locations. Then, depending on the characteristics of each provider, different parameters may be required for them to function. Examples of providers include Nominatim from OpenStreetMap, Google Maps, custom layers such as points of interest or street data, etc.
The plugin has very interesting options, such as configuring and establishing the priority order in which the results obtained from each of the providers used in the searches will be displayed.
And, of course, it is possible to configure custom providers for each territory, as we have done in various projects. Examples include Cartociudad in Spain or the Geocoder of the IDE in Uruguay.

Por supuesto el plugin dispone de funcionalidad tanto de geocodificación directa (la localización de una ubicación mediante una cadena de búsqueda) como geocodificación inversa (averiguar la dirección marcando una posición en el mapa).
Desde la parte de administración, en la lista de proveedores de búsqueda se les puede indicar una categoría (para englobar los resultados de ese proveedor bajo un separador) y se les puede asignar un icono que marcará cada una de las sugerencias propuestas . Luego, según las características de cada uno, se requerirán unos parámetros u otros para que puedan funcionar. Ejemplos de proveedores: Nominatim de OpenStreetMap, Google Maps, capas propias de – por ejemplo – puntos de interés o callejero, etc.
El plugin tiene opciones muy interesantes, como configurar y establecer el orden de prioridad en el que se mostrarán los resultados obtenidos de cada uno de los proveedores utilizados en las búsquedas.
Y, por supuesto, se pueden configurar proveedores propios de cada territorio, como así hemos realizado en diversos proyectos. Ejemplos: Cartociudad en España o el Geocoder de la IDE de Uruguay.

The 2023 OGC Tiling Interfaces Code Sprint – How it went!
sur Open Geospatial Consortium (OGC)On June 12-14, 2023, OGC held its 2023 Tiling Interfaces Code Sprint at OGC Strategic Member NGA’s Moonshot Labs in St. Louis, Missouri. The code sprint focused on a select set of Application Programming Interface (API), database, and encoding standards related to map tiles. An API is a standard set of documented functions that expose the capabilities supported or data offered by an application, or service to other applications.
OGC code sprints are collaborative and inclusive events that support the development and refinement of open standards by providing software developers the time and space to focus on projects that implement the standards.
By experimenting with emerging ideas in the context of geospatial standards, OGC code sprints help improve interoperability of existing standards by experimenting with new extensions or profiles, and building or enhancing software products to implement the standards.
In addition, the sprints’ mentor streams provide developers with a helping hand when learning how to use the standards and projects so that they can build a working understanding of them that will last beyond the duration of the sprint.
The mentor stream at the Tiling Interfaces Code Sprint included three entry-level tutorials that used practical use-cases to introduce participants to the standards. One tutorial focused on how to serve vector tiles using the OGC API – Tiles standard, while another focused on compliance testing, and the third provided an overview of a web-based product that implements several OGC standards.
The 2023 OGC Tiling Interfaces Code Sprint focused on the following Standards and specifications:
- OGC API – Tiles: An approved Standard that specifies building blocks for creating Web APIs that support the retrieval of geospatial information as tiles.
- OGC API – Maps: A candidate Standard that specifies building blocks for serving spatially referenced and dynamically rendered electronic maps and charts.
- Changesets API: A prototype specification based on outcomes from OGC Testbed-15 that provides the foundation for a ‘Transactional Tiles API Extension’ for OGC API – Tiles.
- Vector Tiles Extension to GeoPackage: A prototype extension of the OGC GeoPackage Standard to support the use of vector tiles.
- Variable Width Tile Matrix: A grid suited for the whole globe that keeps the data in a geographic Coordinate Reference System.
- Web Map Tile Service (WMTS): The popular OGC Standard that specifies a web service that can serve map tiles of spatially referenced data using tiled images with predefined content, extent, and resolution. The OGC WMTS Standard is the base standard for the WMTS profiles of the US National System for GEOINT (NSG) and the Defense Geospatial Information Working Group (DGIWG).
At its peak, the code sprint had 50 concurrent active users participating remotely across multiple channels on the code sprint’s online platform. In-person participation saw a dozen participants from NGA, OGC, US Army Geospatial Center, UK Defence Science & Technology Laboratory (Dstl), Universitat Autònoma de Barcelona (CREAF), Pixalytics Ltd., Compass, FlightSafety International, and University of Maryland.
Screenshots of a selection of applications deployed for the code sprint are shown below.

The presentation enabled participants to identify an approach for how QGIS and GDAL could support workflows that involve the downloading of vector tiles and map tiles from an OGC API and the storage of the tiles in a GeoPackage.
Figure 7 (click to enlarge)
Contains OS data © Crown copyright and database right 2023.Figure 7 shows a map created by KORTxyz from the vector tiles distribution of the Ordnance Survey Zoomstack product and accessed through an OGC API – Tiles interface.
What did we learn?The following are some of the lessons learned during the code sprint, and recorded by participants on the final day of the code sprint.
There is a need for further developer guidance documents for implementing OGC API – Tiles, particularly with regard to the placement on tileset resources. Such guidance should include clarification on the handling of relation types such as ‘conformance’ that can be represented as simple string literals and also as URLs.
There is a need to make sure there exists a well-documented user journey for people that want to use OGC API – Tiles through QGIS. For example, documentation to take a beginner from their first line of code to a more advanced stage.
Although some work has been done on vector tiles within OGC, more work is needed to advance the specification towards becoming an OGC Standard. Some of the work that could be carried out includes, for example, development of a Best Practice document. RBT could provide a foundation for such a Best Practice.
For future code sprints, it may be necessary to introduce participants to the basics of the specifications that are in focus for the code sprint ahead of the event. Further, it would be helpful to participants such as students to have specific instructions to help participants prepare for the code sprint.
Conclusions and RecommendationsThe code sprint met all of its objectives and achieved its goal of supporting the implementation of open geospatial standards within the developer community. Furthermore, the code sprint provided an environment for development and testing of prototype implementations of open standards and a starting point for developers to learn about the draft and approved standards, as well as their implementations.
The participants identified the following recommendations at the conclusion of the code sprint:
- A future code sprint that includes the OGC CDB Standard should examine how vector tiles could be embedded in such a data store.
- AGC is interested in how the World Mercator coordinate reference system (reference EPSG:3395) could support vector tiles in a GeoPackage. The question for future experimentation is whether this could be specified so that it can be implemented by any developer.
- The application of OGC API – Tiles in partitioning and indexing content from an implementation of the OGC SensorThings API standard and the OGC API – Connected Systems candidate standard could be explored in a future code sprint.
- An initiative to develop content for the OGC e-learning resource and the OGC Compliance Program could help improve interoperability between implementations of OGC Standards.
- Although OGC API – Tiles is an approved standard, there is some work to do around addressing interoperability issues in the different implementations (see for instance this Issue on the OSGeo gdal GitHub.

gvSIG Team: Inventario de empresas y vertidos en áreas industriales con gvSIG Online
sur Planet OSGeoPara el Ayuntamiento de Náquera se ha desarrollado un conjunto de herramientas, integradas con gvSIG Online con el objetivo de llevar a cabo la creación y gestión del inventario georreferenciado de las empresas ubicadas en las áreas industriales del municipio.
La herramienta web sirve para la captación de información de empresas (sector de actividad, volumen de negocio, número de empleados, características de los residuos, tomas de agua, salidas de emergencias…) situadas en los polígonos industriales y para su integración en un visor de mapas de gvSIG Online con la geolocalización de dichas empresas.
Parte de la información es introducida por las propias empresas mediante diversas herramientas desarrolladas con este objetivo. Por otro lado, el sistema dispone de opciones de validación de la información para los técnicos municipales. Además, la solución desarrollada también posee funcionalidad para gestionar el registro de empresas, de forma que puedan acceder al sistema y modificar sus datos.
Después de la introducción de los datos y validación por parte del Ayuntamiento la herramienta genera una capa que permite consultar las fichas de empresas registradas en la herramienta web desde el geoportal de áreas industriales de Nàquera. Al pulsar en el mapa, se muestra la información básica de la empresa, teniendo la opción de consultar la ficha completa de cada una de las empresas.
Por otro lado, la herramienta permite consultar los diferentes sectores de empresas por actividad, activando o no la visibilidad de cada sector, de todos los sectores o de aquellos que se seleccionen.
Del mismo modo que se rellenan los datos de la ficha de empresa, existe la opción de rellenar la información correspondiente a una ficha de control de vertidos. Estas fichas de control de vertidos pueden ser consultadas desde el geoportal de áreas industriales, siempre con acceso restringido. Cada empresa está asignada a Estaciones de Muestreo, de forma que cuando se detecta una incidencia en una estación de muestreo se pueden listar todas las empresas vinculadas a dicha estación de muestreo.
Un ejemplo más de como gvSIG Online se ha convertido en una solución idónea para gestionar la información de un municipio, en este caso de sus áreas industriales.

OGC proud to create European Innovation Events and Open Knowledge
sur Open Geospatial Consortium (OGC)The Open Geospatial Consortium (OGC) is proud to co-organize and sponsor upcoming European Innovation Events such as Data Week Leipzig 2023. The Location Innovation Academy continues to grow and support Open Knowledge.
Data Week Leipzig 2023 will run next week, June 26-30, 2023, in Leipzig, Germany, and online. OGC will present its new OGC European Innovation Days event and more at the event. Data Week Leipzig is an innovative networking and exchange event that highlights scientific, economic, and social perspectives of data and its use, and where industry, citizens, science, and public authorities can enter into dialogue. Special topics of Data Week Leipzig 2023 are Semantic Interoperability, the European Green Deal, NetZero Cities, sustainable, resilient development, and the Location Innovation Academy (see below). Digital strategies will be presented and discussed from the European to the local Leipzig City level. The event will be streamed to viewers worldwide.
Findings of the AD4GD (All Data for Green Deal) and GeoE3 Projects will be included in the topics of Monday’s European Innovation Day at Data Week. Several sessions on Data Spaces, Digital Twins, and Urban Planning will be held across Monday and Tuesday, while Wednesday will offer several workshops on Semantic Interoperability and the new “OGC Rainbow” environment – which represents the state-of-the-art in enabling semantic interoperability.
The Growing Location Innovation Academy
Starting as a hub for the distribution of knowledge and skills related to the publication and use of location-based information, the Location Innovation Academy is expanding its horizons and finding a larger audience, with a view to provide the foundation for the future OGC Academy. The Academy was presented during last week’s Open Data & Open Knowledge Workshop, hosted by GEO. The workshop emphasized the importance of open knowledge and open academies that provide not just information but also grow students’ ability to correctly interpret the available information to support better and more informed decision-making.Don’t miss the hybrid hands-on session providing detailed insights about the Location Innovation Academy during the European Innovation Days at Data Week Leipzig 23 on Tuesday June 27 @ 17:00 CEST.
Learn more at academy.ogc.orgGeoE3 recently published a blog post entitled “Interested in new technologies of data services?” that outlines the free Data Service Management course offered by the Location Innovation Academy. The course teaches students everything they need to know about OGC API standards and how they can be implemented to manage geospatial data services more efficiently. This course and others offered by the Academy address the need, identified during GeoE3, to lower the barrier of entry for new users of APIs.
More information on the academy and the courses offered is available on GeoE3’s Location Innovation Academy information page. The Location Innovation Academy is hosted by OGC at academy.ogc.org.

iCarto Blog: Creating a Shareable QGIS Project with PostgreSQL/PostGIS Connections
sur Planet OSGeoOne of the numerous features offered by QGIS is the ability to save our projects. We can store all the specific configurations, layers, styles, analyses, and other aspects in a file, allowing us to return to that point at any time. This is particularly useful when dealing with complex project organization. This functionality is also very helpful for collaborative work, as we can exchange projects with other team members.
However, when creating a project for sharing, certain aspects need to be taken into account, such as including connections to a database. In this article, we will discuss some interesting key points for accomplishing this.
Database Connections in QGIS Projects: The Recommended ApproachMost of the time, when creating a QGIS project with PostgreSQL/PostGIS layers, the data connection details are directly written, including storing the password in plain text within the project.
When done this way, within the project file created by QGIS with .qgz/.qgs extension, there will be a line like this:
<datasource>dbname='test' host=localhost port=5439 user='test_user' password='test_user' sslmode=disable key='id' srid=4326 type=Point checkPrimaryKeyUnicity='0' table="public"."cities" (geom)</datasource>
This approach creates several problems when it comes to deploying the project or sharing it with others:
- Usernames and passwords need to be shared among several people, making it impossible to establish logical individual or group permissions.
- If we don’t hardcode the username and password, every person using the project will have to enter the data each time.
- Passwords are stored in plain text.
- If the server needs to be changed, for example, from a testing environment to a production one, the project needs to be modified.
- …
Although there are some ways to improve this situation, such as using
.pgpass
, using the Authentication Manager, or using custom embedded scripts within the project, they are not the best options and have issues.The best approach, or at least the one we can recommend based on our experience, is to associate the connection details with an identifier (a pre-agreed name) and establish the connection in QGIS using the same identifier.
PostgreSQL allows achieving this through the Connection Service File. It is a text file located in Linux at
~/.pg_service.conf
and in Windows at%APPDATA%\postgresql\.pg_service.conf
, and it would look like this:[test] host=localhost port=5439 dbname=test user=test_user password=test_user sslmode=disable # Avoid hardcode the password in prod [production] host=my.production.server port=5432 dbname=my_project user=my_user
In QGIS, the connection would be established like this:
Here, you only need to fill in the connection name and the service name, which will be our identifier (the text within the brackets) in the
.pg_service.conf
file. This is explained in more detail in the QGIS documentation.The advantages of using connections with an identifier are clear and solve the aforementioned problems. One person can prepare the project locally, and then, when moving to production, they only need to send the project and indicate the connection name and parameters that the rest of the team should fill in the
.pg_service.conf
file.Furthermore, since this file is directly managed by libpq, the standard PostgreSQL client library used by 99% of applications, this strategy will work with any other client that needs to use that database connection, not just QGIS.
For example, in console commands:
ogrinfo PG:"service=test" cities psql service=test
or in QGIS scripts:
layer = QgsVectorLayer("service=test table=cities (geom)", "Cities", "postgres") QgsProject.instance().addMapLayer(layer)
The Service File allows defining numerous parameters, and few of them are mandatory. For instance, if we don’t define the password, any application using
libpq
will execute a normal workflow to try to discover it: searching in thePGPASSWORD
variable, checking the existence of the.pgpass
file, or directly prompting us to provide it.La entrada Creating a Shareable QGIS Project with PostgreSQL/PostGIS Connections se publicó primero en iCarto.

gvSIG Team: Un vistazo a la Infraestructura de Datos Espaciales de Cullera (IDE)
sur Planet OSGeoLa IDE de Cullera se inició en el área de urbanismo, pero rápidamente se ha extendido a todas las áreas y departamentos municipales. En la actualidad cuenta con decenas de geoportales internos y una serie de visores de mapas públicos, donde consultar información relevante para los ciudadanos y visitantes del municipio.
Con este post vamos a iniciar una serie de artículos en los que os iremos presentando distintas Infraestructuras de Datos Espaciales implantadas con gvSIG Online, que se está convirtiendo en la solución de referencia para IDEs con software libre.
Vamos a repasar solo algunos de los geoportales públicos:
- Turismo: Es el geoportal principal que recopila información relativa al turismo. Agrupa un extenso conjunto de información como oferta hotelera, puntos y zona de Wi-Fi, gastronomía, museos, rutas y sendas turísticas, playas,…
- Movilidad y transporte: Permite consultar información relativa a movilidad como estacionamientos, carriles bici, líneas de autobús, puntos de carga eléctrica,…
- Deportes: Este geoportal está orientado a mostrar los recorridos de diferentes eventos deportivos como la Volta a peu a Cullera, el triatlón, la San Silvestre,…
- Agricultura y actividades cinegéticas: Contiene información de usos del suelo, bancos de tierras,…
- Servicios municipales: Visor de mapas con información de dotaciones municipales como centros sanitarios, bibliotecas, instalaciones deportivas, centros de enseñanza,…
- Playas: ahora que se acerca la temporada estival aquí se puede encontrar información tan interesante como playas accesibles, infraestructuras, banderas azules…
- Urbanismo: el inicio de la IDE, con toda la información típica de este tipo de geoportales relativa al urbanismo (calificación y clasificación) y catastro. Es interesante destacar que tiene normativa urbanística asociada a los elementos geográficos.
- Y más geoportales públicos: infraestructuras, medio ambiente y cambio climático, gestión de residuos, ciudadanía, arqueología, sanidad, fiestas y comercio. Y siguen creciendo…
La dirección de la página principal de la IDE de Cullera es:
El principal contenido de la IDE, además de los servicios de mapas, son sus geoportales. En el siguiente enlace se pueden visualizar todos los visores de mapas actualmente disponibles:
También es interesante hacer referencia a que gvSIG Online permite generar “Vistas compartidas” que no son más que URLs que permiten compartir una configuración concreta de un geoportal, en la que hay una serie de capas visibles o invisibles por defecto e, incluso, un determinado encuadre (zona o territorio del municipio visible al entrar).
Desde la web de turismo del Ayuntamiento de Cullera, accesible en el enlace [https:]] hay vistas compartidas en distintas secciones de esta web: playas, rutas naturales, monumentos… todas estas vistas compartidas enlazan con distintas configuraciones del geoportal de Turismo que forma parte de la IDE.
Por último, para acabar, indicar que entre las mejoras previstas para los próximos meses está la integración con el gestor de expedientes (SEGEX de Sedipualba) y la incorporación de gvSIG Mapps como app para toma de datos en campo.

OPENGIS.ch: Unterstützung für WMTS im QGIS Swiss Locator
sur Planet OSGeoDas QGIS swiss locator Plugin erleichtert in der Schweiz vielen Anwendern das Leben dadurch, dass es die umfangreichen Geodaten von swisstopo und opendata.swiss zugänglich macht. Darunter ein breites Angebot an GIS Layern, aber auch Objektinformationen und eine Ortsnamensuche.
Dank eines Förderprojektes der Anwendergruppe Schweiz durfte OPENGIS.ch ihr Plugin um eine zusätzliche Funktionalität erweitern. Dieses Mal mit der Integration von WMTS als Datenquelle, eine ziemlich coole Sache. Doch was ist eigentlich der Unterschied zwischen WMS und WMTS?
WMS vs. WMTSZuerst zu den Gemeinsamkeiten: Beide Protokolle – WMS und WMTS – sind dazu geeignet, Kartenbilder von einem Server zu einem Client zu übertragen. Dabei werden Rasterdaten, also Pixel, übertragen. Ausserdem werden dabei gerenderte Bilder übertragen, also keine Rohdaten. Diese sind dadurch für die Präsentation geeignet, im Browser, im Desktop GIS oder für einen PDF Export.
Der Unterschied liegt im T. Das T steht für “Tiled”, oder auf Deutsch “gekachelt”. Bei einem WMS (ohne Kachelung) können beliebige Bildausschnitte angefragt werden. Bei einem WMTS werden die Daten in einem genau vordefinierten Gitternetz — als Kacheln — ausgeliefert.
Der Hauptvorteil von WMTS liegt in dieser Standardisierung auf einem Gitternetz. Dadurch können diese Kacheln zwischengespeichert (also gecached) werden. Dies kann auf dem Server geschehen, der bereits alle Kacheln vorberechnen kann und bei einer Anfrage direkt eine Datei zurückschicken kann, ohne ein Bild neu berechnen zu müssen. Es erlaubt aber auch ein clientseitiges Caching, das heisst der Browser – oder im Fall von Swiss Locator QGIS – kann jede Kachel einfach wiederverwenden, ganz ohne den Server nochmals zu kontaktieren. Dadurch kann die Reaktionszeit enorm gesteigert werden und flott mit Applikationen gearbeitet werden.
Warum also noch WMS verwenden?
Auch das hat natürlich seine Vorteile. Der WMS kann optimierte Bilder ausliefern für genau eine Abfrage. Er kann Beispielsweise alle Beschriftungen optimal platzieren, so dass diese nicht am Kartenrand abgeschnitten sind, bei Kacheln mit den vielen Rändern ist das schwieriger. Ein WMS kann auch verschiedene abgefragte Layer mit Effekten kombinieren, Blending-Modi sind eine mächtige Möglichkeit, um visuell ansprechende Karten zu erzeugen. Weiter kann ein WMS auch in beliebigen Auflösungen arbeiten (DPI), was dazu führt, dass Schriften und Symbole auf jedem Display in einer angenehmen Grösse angezeigt werden, währenddem das Kartenbild selber scharf bleibt. Dasselbe gilt natürlich auch für einen PDF Export.
Ein WMS hat zudem auch die Eigenschaft, dass im Normalfall kein Caching geschieht. Bei einer dahinterliegenden Datenbank wird immer der aktuelle Datenstand ausgeliefert. Das kann auch gewünscht sein, zum Beispiel soll nicht zufälligerweise noch der AV-Datensatz von gestern ausgeliefert werden.
Dies bedingt jedoch immer, dass der Server das auch entsprechend umsetzt. Bei den von swisstopo via map.geo.admin.ch publizierten Karten ist die Schriftgrösse auch bei WMS fix ins Kartenbild integriert und kann nicht vom Server noch angepasst werden.
Im Falle von QGIS Swiss Locator geht es oft darum, Hintergrundkarten zu laden, z.B. Orthofotos oder Landeskarten zur Orientierung. Daneben natürlich oft auch auch weitere Daten, von eher statischer Natur. In diesem Szenario kommen die Vorteile von WMTS bestmöglich zum tragen. Und deshalb möchten wir der QGIS Anwendergruppe Schweiz im Namen von allen Schweizer QGIS Anwender dafür danken, diese Umsetzung ermöglicht zu haben!

Lutra consulting: Webinar: Processing LiDAR data in QGIS 3.32
sur Planet OSGeoJoin this webinar to learn more about the new features in QGIS to process LiDAR data:
Date: Monday, June 26, 2023 at 14:00 GMT
Duration: 30 minutes + 15 minutes Q&A session
Speaker: Martin Dobias, CTO at Lutra Consulting with more than 15 years of QGIS development experience
DescriptionPoint clouds are an increasingly popular data type thanks to the decreasing cost of their acquisition through lidar surveys and photogrammetry. On top of that, more and more national mapping agencies release high resolution point cloud data (spanning large areas and consisting of billions of points), unlocking many new use cases.
This webinar will summarize the latest QGIS release 3.32 and the addition of tools for point cloud analysis right from QGIS Processing toolbox: clip, filter, merge, export to raster, extract boundaries and more - all backed by PDAL library that already ships with QGIS, without having to rely on third party proprietary software.
This work was made possible by the generous donations to our crowdfunding.

Lutra consulting: Virtual Point Clouds (VPC)
sur Planet OSGeoAs a part of our crowdfunding campaign we have introduced a new method to handle a large number of point cloud files. In this article, we delve into the technical details of the new format, rationale behind our choice and how you can create, view and process virtual point cloud files.
RationaleLidar surveys of larger areas are often multi-terabyte datasets with many billions of points. Having such large datasets represented as a single point cloud file is not practical due to the difficulties of storage, transfer, display and analysis. Point cloud data are therefore typically stored and distributed split into square tiles (e.g. 1km x 1km), each tile having a more manageable file size (e.g. ~200 MB when compressed).
Tiling of data solves the problems with size of data, but it introduces issues when processing or viewing an area of interest that does not fit entirely into a single tile. Users need to develop workflows that take into account multiple tiles and special care needs to be taken to deal with data near edges of tiles to avoid unwanted artefacts in outputs. Similarly, when viewing point cloud data, it becomes cumbersome to load many individual files and apply the same symbology.
Here is an example of several point cloud tiles loaded in QGIS. Each tile is styled based on min/max Z values of the tile, creating visible artefacts on tile edges. The styling has to be adjusted for each layer separately:
Virtual Point CloudsIn the GIS world, many users are familiar with the concept of virtual rasters. A virtual raster is a file that simply references other raster files with actual data. In this way, GIS software then treats the whole dataset comprising many files as a single raster layer, making the display and analysis of all the rasters listed in the virtual file much easier.
Borrowing the concept of virtual rasters from GDAL, we have introduced a new file format that references other point cloud files - and we started to call it virtual point cloud (VPC). Software supporting virtual point clouds handles the whole tiled dataset as a single data source.
At the core, a virtual point cloud file is a simple JSON file with .vpc extension, containing references to actual data files (e.g. LAS/LAZ or COPC files) and additional metadata extracted from the files. Even though it is possible to write VPC files by hand, it is strongly recommended to create them using an automated tool as described later in this post.
On a more technical level, a virtual point cloud file is based on the increasingly popular STAC specification (the whole file is a STAC API ItemCollection). For more details, please refer to the VPC specification that also contains best practices and optional extensions (such as overviews).
Virtual Point Clouds in QGISWe have added support for virtual point clouds in QGIS 3.32 (released in June 2023) thanks to the many organisations and individuals who contributed to our last year’s joint crowdfunding with North Road and Hobu. The support in QGIS consists of three parts:
- Create virtual point clouds from a list of individual files
- Load virtual point clouds as a single map layer
- Run processing algorithms using virtual point clouds
Those who prefer using command line tools, PDAL wrench includes a build_vpc command to create virtual point clouds, and all the other PDAL wrench commands support virtual point clouds as the input.
Using Virtual Point CloudsIn this tutorial, we are going to generate a VPC using the new Processing algorithm, load it in QGIS and then generate a DTM from terrain class. You will need QGIS 3.32 or later for this. For the purpose of this example, we are using the LiDAR data provided by the IGN France data hub.
In QGIS, open the Processing toolbox panel, search for the Build virtual point cloud (VPC) algorithm ((located in the Point cloud data management group):
VPC algorithm in the Processing toolboxIn the algorithm’s window, you can add point cloud layers already loaded in QGIS or alternatively point it to a folder containing your LAZ/LAS files. It is recommended to also check the optional parameters:
-
Calculate boundary polygons - QGIS will be able to show the exact boundaries of data (rather than just rectangular extent)
-
Calculate statistics - will help QGIS to understand ranges of values of various attributes
-
Build overview point cloud - will also generate a single “thinned” point cloud of all your input data (using only every 1000th point from original data). The overview point cloud will be created next to the VPC file - for example, for mydata.vpc, the overview point cloud would be named mydata-overview.copc.laz
After you set the output file and start the process, you should end up with a single VPC file referencing all your data. If you leave the optional parameters unchecked, the VPC file will be built very quickly as the algorithm will only read metadata of input files. With any of the optional parameters set, the algorithm will read all points which can take some time.
Now you can load the VPC file in QGIS as any other layer - using QGIS browser, Data sources dialog in QGIS or by doing drag&drop from a file browser. After loading a VPC in QGIS, the 2D canvas will show boundaries of individual files - and as you zoom in, the actual point cloud data will be shown. Here, a VPC loaded together with the overview point cloud:
Virtual point cloud (thinned version) generated by the VPC algorithmZooming in QGIS in 2D map with elevation shading - initially showing just the overview point, later replaced by the actual dense point cloud:
VPC output on 2D: displaying details when zooming inIn addition to 2D maps, you can view the VPC in a 3D map windows too:
If the input files for VPCs are not COPC files, QGIS will currently only show their boundaries in 2D and 3D views, but processing algorithms will work fine. It is however possible to use the Create COPC algorithm to batch convert LAS/LAZ files to COPC files, and then load VPC with COPC files.
It is also worth noting that VPCs also work with input data that is not tiled - for example, in some cases the data are distributed as flightlines (with lots of overlaps between files). While this is handled fine by QGIS, for the best performance it is generally recommended to first tile such datasets (using the Tile algorithm) before doing further display and analysis.
Processing Data with Virtual Point CloudsNow that we have the VPC generated, we can run other processing algorithms. For this example, we are going to convert the ground class of the point cloud to a digital terrain model (DTM) raster. In the QGIS Processing toolbox, search for Export to raster algorithm (in the Point cloud conversion group):
VPC layer can be used as an input to the point cloud processing algorithmThis will use the Z values from the VPC layer and generate a terrain raster based on a user defined resolution. The algorithm will process the tiles in parallel, taking care of edge artefacts (at the edges, it will read data also from the neighbouring tiles). The output of this algorithm will look like this:
Converting a VPC layer to a DTMThe output raster contains holes where there were no points classified as ground. If needed for your use case, you can fill the holes using Fill nodata algorithm from GDAL in the Processing toolbox and create a smooth terrain model for your input Virtual Point Cloud layer:
Filling the holes in the DTMVirtual point clouds can be used also for any other algorithms in the point cloud processing toolbox. For more information about the newly introduced algorithms, please see our previous blog post.
All of the point cloud algorithms also allow setting filtering extent, so even with a very large VPC, it is possible to run algorithms directly on a small region of interest without having to create temporary point cloud files. Our recommendation is to have input data ready in COPC format, as this format provides more efficient access to data when spatial filtering is used.
Streaming Data from Remote Sources with VPCsOne of the very useful features of VPCs is that they work not only with local files, but they can also reference data hosted on remote HTTP servers. Paired with COPCs, point cloud data can be streamed to QGIS for viewing and/or processing - that means QGIS will only download small portions of data of a virtual point cloud, rather than having to download all data before they could be viewed or analysed.
Using IGN’s lidar data provided as COPC files, we have built a small virtual point cloud ign-chambery.vpc referencing 16 km2 of data (nearly 700 million points). This VPC file can be loaded in QGIS and used for 2D/3D visualisation, elevation profiles and processing, with QGIS handling data requests to the server as necessary. Processing algorithms only take a couple of seconds if the selected area of interest is small (make sure to set the “Cropping extent” parameter of algorithms).
All this greatly simplifies data access to point clouds:
-
Data producers can use very simple infrastructure - a server hosting static COPC files together with a single VPC file referencing those COPC files.
-
Users can use QGIS to view and process point cloud data as a single map layer, with no need to download large amounts of data, QGIS (and PDAL) taking care of streaming data as needed.
We are very excited about the opportunities that virtual point clouds are bringing to users, especially when combined with COPC format and access from remote servers!
Thanks again to all contributors to our crowdfunding campaign - without their generous support, this work would not have been possible.

Dr. Jeff de La Beaujardiere receives OGC Lifetime Achievement Award
sur Open Geospatial Consortium (OGC)The Open Geospatial Consortium (OGC) is excited to announce that Dr. Jeff de La Beaujardiere has been selected as the latest recipient of the OGC Lifetime Achievement Award. The announcement was made last night during the Executive Dinner in the U.S. Space & Rocket Center at the 126th OGC Member Meeting in GeoHuntsville, AL.
Jeff has been selected for the award due to his long standing leadership, commitment, and support for the advancement and uptake of standards used for the dissemination of Earth Science information.
“I’m so happy that Jeff has been selected to receive the OGC Lifetime Achievement Award,” said OGC CEO, Dr. Nadine Alameh. “Jeff is more than a champion for standards, more than an OGC Gardels award winner, and more than the WMS editor and promoter: Jeff is a role model for many of us in geospatial circles, and has directly and indirectly influenced generations of interoperability enthusiasts to collaborate, to innovate, and to solve critical problems related to our Earth. From OGC and myself, I offer our congratulations and thank Jeff for his technical work – and for being such an inspiration to so many!”
For more than 25 years, Jeff’s support of open standards and OGC’s FAIR mission has improved access to Earth science information for countless users and decision-makers around the globe. Since 1995, Jeff has focused on improving public access to scientific data by pushing for it to be discoverable, accessible, documented, interoperable, citable, curated for long-term preservation, and reusable by the broader scientific community, external users, and decision-makers.
In the OGC community, Jeff is best known as the Editor of the OGC Web Map Service (WMS) Specification: a joint OGC/ISO Standard that now supports access to millions of datasets worldwide. OGC WMS was the first in the OGC Web Services suite of Standards and is the most downloaded Standard from OGC. But most importantly, the OGC WMS Standard truly revolutionized how geospatial data is shared and accessed over the web.
Jeff was also a major contributor to other OGC Standards, including the OGC Web Services Architecture, the OGC Web Map Context, OGC Web Terrain Service, and OGC Web Services Common.
Jeff’s journey with Standards – and his engagement with OGC – started back in 1998 when NASA was leading the effort to implement the Digital Earth program. At that time, Jeff championed interoperability standards as fundamental to realizing the Digital Earth vision. As part of his journey, he has provided leadership to the Geospatial Applications and Interoperability (GAI) Working Group of the U.S. Federal Geographic Data Committee and to the OGC Technical Committee.
In 2002 and 2003, Jeff served as Portal Manager for Geospatial One-Stop, a federal electronic government initiative. He led a team of experts in defining the requirements, architecture, and competitive solicitation for a Portal based on open standards and led an OGC interoperability initiative in developing and demonstrating a working implementation. This was a fast-paced, high-stakes effort involving many companies and agencies building on what today is the OGC Collaborative Solution & Innovation Program.
Jeff has received several awards for his leadership and impact in the many communities that he has participated in throughout his career, including the 2013 OGC Kenneth D. Gardels Award, the 2023 ESIP President’s Award, and the 2003 Falkenberg Award at AGU which honors “a scientist under 45 years of age who has contributed to the quality of life, economic opportunities, and stewardship of the planet through the use of Earth science information and to the public awareness of the importance of understanding our planet.”
With this lifetime achievement award, OGC recognizes and celebrates Jeff’s lifetime of service, and his steadfast support of FAIR geospatial information for the benefit of open science, and society.

Quilting "Golden Light"
sur Planet Geospatial - http://planetgs.comAfter the success of the first experiment with printing one of my mom's photographs on fabric and quilting it last July (see Quilting Fuchsia), we selected seven more images and had those printed at Spoonflower's largest possible size (about 27 x 40 inches without distorting the image). I've since shipped and carried those pieces of fabric all around the United States and even into Canada, twice. Two weeks ago, I finally managed to find the time to sit down and start to quilt again—truly one of my very favourite/favorite activities.
This is the resulting quilt that I created from the photograph "Golden Light" by Elizabeth Root Blackmer (you can see the original image in the middle of her Frozen gallery at BrootPhoto.com). The image is bubbles of air trapped in the ice of a frozen pond.
First of all, I had to find a fabric store. I was staying at my house in Nova Scotia when I finally found the time to quilt, and although I have spent extended periods of time here at the house over the past seven years (I took over the family home), I had never tried to find a place to source fabric here. I mentioned to my farming neighbour/neighbor that I need to ask his wife about a place to get fabric, and he looked at me like I was utterly obtuse. He said something along the lines of: "Everyone goes to Avonport Discount Fabric Centre over in Avonport, up behind the school—how do you not know that?" LOL.
So I asked a few more people over the next few days as I finished up my stack of work-work, and every single person (male and female) said the same thing: go there! So I did. Well, it doesn't look like much from the outside, and it shares a big dirt parking lot with the used auto parts store next door, so I was reasonably skeptical, but oh, what an epic pleasure this place is. Fantastic materials, ample supplies, helpful staff, great prices, and generally, like so many places here in Nova Scotia, a meeting place for friends and family. I've been back quite a number of times since; it's just down the road from my house—not ten minutes away!Anyway, I found the most perfect backing fabric and thread for my project at this lovely store, and had a few wonderful quilting-related conversations with the ladies there while I wandered around looking at everything.
For some odd reason, I decided to use the dining table as my quilting space (but it's just me here this time, so I'm not in anyone's way). It might seem odd, given that I made myself a quilting area in another room, but this space is always warm, and that space doesn't need to be heated, so I ended up out here. By the time this quilt was done, five of the six chairs had been moved away from the table to give me access to all sides of the quilt.
And here is the original printed image.
I started by quilting the ice bubbles with gold thread and used a twisty stitch-line within each circle to make them stand out as separate elements. You can see the backing fabric here as well, a delicious mottled teal.
Then I quilted the darker section in the upper-right quadrant with a brown top thread. I used the diagonal line that runs through the image as the dividing line between the two sections of parallel stitching, and eyeballed the entire quilt from that one line. Teal thread was used for every stitch on the back of the quilt.
I used a variegated thread for the rest of the straight lines. Again, with teal thread on the back.
Quilting so many straight lines was exhausting, but I found my rhythm after a while.
You can really see how the variegated thread looks on the binding. I used three lines of it on the binding to make this element really stand out.
I had to go back to the fabric store to find a suitable edge fabric to use for the binding, but then I found a bias tape that was the perfect colour/color, so I used that.
And here's what the back looks like.
And here it is on the bed in one of the guest rooms ... I go in and visit it often, as I take stretch breaks from work-work and think about which image I'll quilt next ...
I only had one major blooper that I had to reëngineer with this quilt. Oh, and what a drag it was! My camera apparently couldn't register so much teal, so it displayed it as greyish/grayish, but even so, there's the epic snaggle of thread. Ugh.
And here are the test scraps that I used during this project. I can't imagine throwing them out unless I have a record of what they look like. It's that, or staple them into my diary, and that gets cumbersome.

Quilting My Mom's Fuchsia Photograph
sur Planet Geospatial - http://planetgs.comMy mom is an amazing photographer. She captured this image called Fuchsia:
And this is what I recently turned it into: a quilt!
That's my mom there, Elizabeth Root Blackmer, holding the finished product.
She's printed on paper, glass, silk, and aluminum over the years, each with amazing results. The aluminum prints immediately below are absolutely stunning in person, and the silks below that were beyond ethereal.
She recently had a show at a photography gallery that included seventy of her various prints. You can view more of her work on her website: BrootPhoto.com.
It seemed time to combine our interests and print one of her images on quilting fabric. Neither of us was completely satisfied with the saturation of the print on the fabric, but for a prototype, it provided us with what we needed to know for the next time.
Here's what I started with: the image printed on a yard of fabric, a yard of solid fuchsia for the backing, and seven colors of thread.
For those who might wonder, the fabric was printed by Spoonflower. We've since put in another order and are hoping for more accurate saturation of the colors.
Here's what the original printed fabric looked like just after it had been washed and ironed. The printed image measured 25 by 40 inches, and by extension, the quilt came out measuring just shy of that.
It was difficult to know where to start quilting as I didn't have a plan and was just winging it. I figured that I'd begin with the small white bits and sewed them directly onto scraps of batting so that they were tamped down to something (if not, washing the quilt in the future could make a huge mess of things when the batting wads up).
Also, I wanted the white bits—which were mostly droplets—to have a slightly 3D feel to them. Here's what the back looked like with the bits of quilted batting; I then cut carefully around the shapes.
As an example of how the white islands look on the final product, here's a preview:
Then I placed a whole piece of batting on the back and started quilting the darkest color on the fabric with my darkest purple thread. This time it was the printed fabric and the batting, but still without the final fabric backing (you'll understand why when you read about my topo lines below).
Some of the light and bright green also needed this pre-backing treatment as there were islands of those colors within the fabric that needed to be captured before the more prolific colors got quilted. In the following image, the purples had also been quilted, but you can see where the greens existed as islands—unreachable from any edge.
Once the colors that existed as islands were quilted to the batting, I layered the fuchsia backing fabric to the sandwich of printed fabric and batting, and started quilting the larger swaths of color that ran from the edges all the way in and then back out again.
I'm not sure how many of you know this, but in my real life, I'm a cartographer. I love me some topo lines, so I quilted this such that the back looks like a topo map. Plus, I freaking loathe tying the hundreds of knots in the back of a quilt (I always think they look messy and I know that they will eventually come loose and unravel). As such, I quilted from one edge into the image and back out again, avoiding the need to tie knots—instead, I backstitched the heck out of each thread's beginning and ending. This is what the back of the completed quilt looks like because of this method. Dude: topo map!
So, that's why I quilted this quilt the way I did, first to bits of batting, then to a whole piece of batting, and then with the fabric backing. Also, I quilted around the bubbles as best as I could while going in and out, and used the various thread colors to create the visual texture of the piece.
Maybe you can imagine the maddening forethought it took to freehand each of these lines so that they didn't overlap at any point but so that enough of the complete layers of the quilt were actually stitched together.
Once all the quilting was done, to ensure that none of my backstitched threads were ever going to release, I double stitched around the whole edge of the image and then I cut everything away except for about a quarter-inch of white around the remaining image.
I had originally planned to add a traditional border to the quilt, but decided against it. Instead, I sacrificed a small percentage of the image all the way around to create a border by carefully double-folding the edges of the quilt all around and stitching them into place.
And once again, I'll mention how annoying I find it to tie knots, so I very carefully stitched all the way around and created all the quadruple (at least) stitching on all the corners using one freaking thread. Epic win!
So really, except for the one blasted thread that broke during quilting and that I had to repair with a knot, there is only one other visible knot in this entire quilt!
Oh, and this is where this quilt was made—in Tenants Harbor, Maine:
I've been visiting my parents for a few months and as a Mother's Day gift I painted out this room for my mom—it went from yellow and white to a light grey on all walls and ceiling, and with fresh bright white trim throughout. Before I moved her back into the room, I took it over as an office and quilting space. The light in here is awesome and her photography will look amazing in here. Or maybe some quilts ...
