We are very pleased to welcome Jochen to Heidelberg and to our research group! Dr. Jochen Albrecht is a professor for Computational and Theoretical Geography at Hunter College in New York City.…

  • CfP: Transactions in GIS special issue on “Open Source Geospatial Science, Software and Education”

    Special issue information: The last decade has seen a rapid growth in open source geospatial software and data developments. Open geospatial data applies the principles of free and openness to geospatial information, allowing communities to collaborate on a data product. Applying the lessons learned in the open source industry to geo-data collection and maintenance has…

  • Simulate LiDAR Acquisitions with HELIOS

    Did you ever consider planning and testing your LiDAR campaign in a computer simulation? Would you like a flexible means to generate 3D point cloud data for developing or testing methods? This is easily possible with the laser scanning simulation framework HELIOS (Heidelberg LiDAR Operations Simulator). There have been major new developments since the first…

  • Over 50 Open Source GIScience Repositories on GitHub

    The GIScience Research Group at Heidelberg University and the Heidelberg Institute for Geoinformation Technology (HeiGIT) are happy to share the their GIScience github repository contains now already over 50 open source repositories and it’s still growing. These contain results from several research projects and in particular also some very active long term activities. Most of the tools…

  • Integrating MapSwipe and HOT Tasking Manager

    The MapSwipe app allows you to mark buildings and roads on satellite imagery within just a few seconds by tapping on your smartphone. Thousands of volunteers contributed to MapSwipe so far and it is just incredible how big the areas are that have been scanned (also see : With one swipe or tap you put…

  • GIScience Heidelberg joins OSGeo GeoForAll Labs

    The GIScience Research Group at Heidelberg joined the OSGE GeoForAll initiative and network as an Open Source Geospatial Laboratory and Research Center. GIScience Heidelberg is supporting free and open GI software, open GI standards (OGC), open Geo-Data (e.g. OpenStreetMap and other VGI), open access publication and GIS education in many ways. This is demonstrated already…

  • Matching GPS trajectories to street segments – an open source implementation

    We would like to inform about a new open source tool that allows matching of GPS trajectories to corresponding street segments. The tool implements a simplified version of the algorithm presented by Zhang et al. (2010). It is a JAVA based implementation and has been put under LGPL license. You can access the source code…
