FOSS4GNL 2025

Ik ben als hobbyist actief bij OpenStreetMap sinds 2020. Ik zet van alles op de kaart en ben ik ook veel bezig om bestaande data te onderhouden. Daarbij maak ik regelmatig gebruik van Overpass en ik heb mezelf aangeleerd hoe ik daarmee overweg kan.

I am an assistant professor of urban design and analytics at TU Delft, passionate about asking spatial and non-spatial questions, mostly with R. As co-coordinator of spatial data and GIS education in the Department of Urbanism, I am engaged in building our students capacity, skills and knowledge for evidence-based spatial design and planning. I co-initiated Rbanism, a community of R users that aims to empower urbanism researchers, students, educators and practitioners to use open-source software and related open-science practices effectively and with confidence. Currently, I focus on developing an open-source tool for urban river space delineation.

With an MSc in Geo-information Science and a BSc in Computer Science, I dedicate my skills to ecology and wildlife conservation efforts, using Remote Sensing, AI, and GIS.

Francesco is a Senior Research Software Engineer at the Netherlands eScience Center, the Dutch national center of expertise for software in academic research. In his position, he collaborates with researchers on topics related to Environment and Sustainability, combining experience in data handling and HPC with a more recently developed passion for geospatial applications.

Landscape-ecologist, cartographyer and GIS-allrounder.

Met meer dan 20 jaar ervaring als fysisch geograaf gespecialiseerd in GIS en Remote Sensing ben ik momenteel Associate Professor Open Science en Digitale Innovatie aan het IHE Delft Institute for Water Education. Daarnaast bied ik consultancy, training en coaching aan in open source GIS via mijn bedrijf, QWAST.

Ik ben een actief lid van de QGIS-gemeenschap, een gecertificeerde QGIS-trainer en medeoprichter/bestuurslid van de Nederlandse QGIS-gebruikersgroep. Ik heb het GIS OpenCourseWare-platform opgezet, dat gratis cursusmateriaal biedt over QGIS, Python, Mergin Maps, Google Earth Engine en meer. Ook heb ik de PCRaster Tools-plugin voor QGIS ontwikkeld, die meer dan 70.000 keer is gedownload. Daarnaast ben ik mede-auteur van het boek QGIS for Hydrological Applications en beheer ik een YouTube-kanaal met meer dan 30.000 abonnees. Als lid van QCooperative ben ik goed verbonden met de beste ontwikkelaars van open source GIS.

CEO/Owner of GeoCat BV, GeoCat Canada Ltd and GeoCat Geospatial S.L (Spain)
Chair and founder of the GeoNetwork opensource
OSGeo Board of Directors

GeoCat was founded by Jeroen in 2007. Jeroen studied Tropical Forestry at Wageningen University specialising in GIS and Remote Sensing. Following graduation in 1997, he worked for the UN Food and Agricultural Organization (FAO) in Rome for nine years. Jeroen held various positions for the FAO in GIS/remote sensing and established the GeoNetwork opensource project. The FAO GeoNetwork is the first implementation based on this software, releasing a large quantity of geospatial data to the public.

Today GeoNetwork opensource is widely used as geospatial catalogue application with implementations from smaller projects to national and international level catalogs including National Geospatial & Open Data Registries and the INSPIRE GeoPortal in the EU.

Jeroen has been promoting the use of international standards and Free and Open Source Software for geographic data and information for over twenty years now. Jeroen is Project Officer for the GeoNetwork opensource project. He currently serves on the OSGeo Board, and did so in 2007 & 2008. He is a Charter member since the early days of OSGeo.

Besides everything geospatial Jeroen loves travel, carpentry, working on his overland truck, study Carl Jung’s Analytical Psychology, and walk, work and live outside.

• Automating Civil Engineering Processes with Grasshopper, Python, C# and whatever other tools are best for the job at hand.
• Integrating BIM, GIS, Geotechnical and Geophysical Data.
• 3D Ground Modelling and uncertainty quantification.
• Open Source Software that I'm a big fan of:
- Bedrock, the open source foundation for ground investigation data, subsurface modelling and Geo-BIM.
- Speckle, the platform for 3D (BIM & GIS) data.
- Geological & Geophysical Modelling: GemPy, pyGIMLi, SimPEG
- GIS: Python for GIS, QGIS, MapLibre, OpenLayers
- OpenBIM: IfcOpenShell, IFC.js (ThatOpenEngine nowadays)

I am a freelance GIS and web developer interested in the value and limitations of AI for creating societal value.

Junior GIS Specialist at Geodienst

MSc in Geo-Information Science.

I am an Assistant Professor at the University of Twente, Faculty of Geo-Information Science and Earth Observation (ITC), Department of Geo-Information Processing (GIP), Enschede, The Netherlands.
My primary research interest has been in the intersection of artificial intelligence (AI) and geodata processing (or GeoAI, in short). During Ph.D., I worked on solutions based on semantic web concepts/technologies and AI to generate geodata processing workflows automatically. After the Ph.D., I extended my research further into the spatial data science and big data processing fields, where I have been using machine learning (ML) for spatiotemporal modelling in different application areas, including environmental monitoring, analysis and assessment, disaster management, and spatial epidemiology. I exploited big data processing technologies and deep learning (DL) methods to extract information from the massive amount of spatial data collected for environmental phenomena. I have also been working on geospatial social media analysis using Natural Language Processing (NLP) methods.
Currently, I am working in the following directions:
- Large Language Models (LLM) and Multimodal LLMs (MLLM)
- MLOps and automation of geoprocessing workflows
- eXplainable Artificial Intelligence (XAI)
- Spatial and spatiotemporal effects in modeling using ML/DL
- Spatial data fusion

Ontwikkelaar voor de Provincie Zuid-Holland

Xiaolu Hu (1986) works as a landscape architect and researcher at the Applied Spatial Research team of Wageningen Environmental Research. She has been involved in various Dutch spatial planning projects with a long-term vision in the past years. According to Xiaolu, the best landscape naturally grows from the soil of the place. The landscape design and planning can only become successful through an open co-creation process with embedded knowledge of landscape dynamics. This requires a GIS-based tool, especially designed for co-creation workshops. A few years ago, Tangible Landscape (TL) drew her attention. Since 2024, Xiaolu has coordinated a project team to develop TL into an applicable tool for the atelier session in visualizing the conjunction area of the Rhine and Waal. It received a lot of positive feedback from participants in the atelier session, such as the provincial government, water board, engineering company, and design firms. Most participants agreed that TL can both help their understanding of landscape dynamics and encourage them to join the design process. In 2025, the TL team will continue its further development for TL 2.0 with wider application scopes.
