Flood risks in Honduras
The Sketch Map Tool was used in a joint effort between the Honduran Red Cross and the municipal government to update the municipal response plan and develop an annex focused on anticipatory actions. Participants were asked to map local knowledge about areas affected by flooding and critical infrastructure. The Sketch Map Tool was used during…

New release of ohsome-planet: Even faster processing of OSM history data in GeoParquet format
A new version of ohsome-planet (codename “Sjælland”) has been released. It is the newest version of HeiGIT´s command line tool, which transforms OpenStreetMap (history) PBF files into into an analysis-ready data format. We illustrate what ohsome-planet can do by assessing how many OSM edits used Bing Imagery as reference source. What is ohsome-planet? Working with…

New Paper “Utilizing large language models to simulate parking search”
A study published on ScienceDirect evaluates the capability of LLMs to mimic human-like decision-making patterns in parking scenarios. Through experiments, researchers reproduce realistic trade-offs between cost, distance, and availability, while reflecting sociodemographic influences and bounded rationality. Parking behavior research traditionally focuses on how drivers choose parking locations, types, and search strategies, distinguishing between static and…

Release of QGIS plugin ORSTools v.2.0.0 & QGIS User Conference
What is ORSTools? With ORSTools, most of the functionalities of openrouteservice are directly accessible in QGIS. The plugin offers a toolset, including routing, isochrone generation and matrix calculations. These functions can be used interactively in the map canvas or applied to point files within the processing framework. Output files come with rich attribute data such…

Heat perception of Heidelberg residents using the Sketch Map Tool and KoboToolbox
Students of the Institute of Geography at Heidelberg University explored local perceptions of urban heat in Heidelberg’s old town as part of a 2024 seminar on GIS for Disaster Risk Reduction and Humanitarian Aid. The project, supported by Heidelberg Institute for Geoinformation Technology (HeiGIT), tested participatory mapping using the Sketch Map Tool combined with KoboToolbox. The…

LaVerDi Project: Integrating OSM and satellite data for landscape monitoring
This project explores how OpenStreetMap data can complement satellite imagery for tracking land cover changes in Germany. Using a small test area, we compare datasets over time to better understand how real-world changes are reflected in OSM—and how this knowledge can support automated monitoring. The Federal Agency for Cartography and Geodesy (BKG) has partnered with…

New Paper “Lessons in Traffic: Nairobi’s School Term Congestion and Equity Challenges”
This study, published at African Transport Studies, investigates the impact of school sessions on traffic congestion in Nairobi, highlighting how children’s mobility needs are often overlooked in transport planning. The paper explores how poor integration of school-related travel into urban transport planning contributes to traffic congestion in Nairobi. While the conventional response to congestion has…

New Paper in Nature “OSMlanduse a dataset of European Union land use at 10 m resolution derived from OpenStreetMap and Sentinel-2”
The paper, published in Nature Scientific Data, presents the first high-resolution (10m or finer) land use map of the European Union derived from a large-scale fusion of OpenStreetMap (OSM) and Copernicus Sentinel-2 data. Leveraging citizen-generated data and remote sensing, the authors demonstrate a scalable and globally applicable methodology to fill thematic and spatial gaps in…

New paper “Corporate Mapping in OpenStreetMap – shifting trends in global evolution and small-scale effects”
Since 2016, corporate involvement in OpenStreetMap (OSM) has grown significantly, with major contributors such as Apple, Microsoft, Meta, and Amazon making substantial edits to the map on a global scale. These efforts have often focused on filling gaps in high- and medium-income countries, contributing to the overall growth of OSM data. However, this increasing corporate…
