  • Humanitarian OSM Stats: How to monitor humanitarian mapping in the HOT Tasking Manager? – Part 2

    Since 2010 organized humanitarian mapping has evolved as a constant and growing element of the global OpenStreetMap (OSM) community. With more than 7,000 projects in 150 countries humanitarian mapping has become a global community effort. Due to this large amount of projects it can be difficult to get an overview on mapping activity. This is…

  • 3D Winter Wonderland – Multi-method acquisition for snow process research

    A joint field campaign was conducted this week in the snow-covered black forest (Hundseck, 48.643°N, 8.228°E) by the research groups Hydrology and Climatology (Prof. Menzel) and 3DGeo (Prof. Höfle). Regular in-situ surveys are conducted at the site to investigate snow as crucial component of the hydrologic cycle, forest management, and evapotranspiration. Surveys comprise measurement of…

  • HELIOS++ 1.0.0 Software & Preprint Release

    The 3DGeo Research Group is proud to announce the release of their novel ray-tracing based laser scanning simulator HELIOS++! HELIOS++ is a general-purpose simulation software for virtual laser scanning data acquisition. Such data can be used to complement real data in many use cases. Some examples include the generation of training data for machine learning,…

  • Erstes Handbuch zur Veranstaltung von Mapathons im Deutschen Roten Kreuz

    Das Handbuch zur Veranstaltung von Mapathons im Deutschen Roten Kreuz (DRK) ist da! In dem Handbuch wird beschrieben, was bei der Durchführung eines Mapathon zu beachten ist. Es beginnt mit der Frage, was überhaupt ein Mapathon ist und erklärt warum und wie durch die Durchführung von regelmäßigen Mapathons z.B. im Rahmen von Bereitschaftsabenden, wichtige Geodaten…

  • Updated OSM Healthcare in Senegal (2020)

    OpenStreetMap (OSM) offers many possibilities and holds potential in the area of freely available infrastructure data for the health sector. Nevertheless, it is important to underline that the quality of the information is different in each country, since the mapping activity is strongly affected by the size of the community of volunteers. Monetary barriers prevent…

  • Accessibility to pharmacies in Germany with 15km Covid-19 restriction

    Current lockdown regulations in Germany state that – in many but not all federal states – travel in COVID-19 hotspot regions is only allowed up to 15km distance. This has raised concerns since a 15km radius has been perceived by some as a serious constraint especially in rural regions. Clearly, this might prevent visits to…

  • 4D change analysis for improving our understanding of dynamic landscapes

    Time series of topographic point clouds offer great possibilities to advance our understanding of dynamic landscapes. To exploit the full information these 4D datasets contain on spatial and temporal properties of natural surface changes, the 3DGeo research group is developing methods for 4D change analysis. These methods are required to answer fundamental questions on the…

  • LandSense Horizon 2020 A Citizen Observatory and Innovation Marketplace for Land Use and Land Cover Monitoring, project successful finished

    The Horizon 2020 LandSense project was concluded successful. Please find a selection of the produced publications and deliverables here. The project has enabled our group to pursue quality aspects of voluntarily collected geo information data and to ramp up efforts related to OSMlanduse. Together with the University of Nottingham (Giles Foody) and Institut national de l’information…

  • Accessibility of covid-19 vaccination centers in Germany

    Updated based on newly available vaccination center locations at the 14th of January 2021. Vaccination of a sufficiently large share of the population is considered the most important action to fight the spread of SARS-CoV -2 and resulting COVID-19 infections. Germany has started together with the majority of EU member states at the 27th of…

  • Auto3Dscapes video about research in 4D change analysis

    This new video by the 3DGeo group presents the challenges of 3D Earth observation and our advances in 4D change analysis in the frame of the Auto3Dscapes project: Direct link to the video: https://youtu.be/Fdwq-Cp0mFY Many thanks to Claudia Denis and David Jäger for helping to realize the video! We are also very happy about the…

  • New Jupyter Notebook: Analysis of Access to Health Care using openrouteservice Isochrones API

    What is the idea behind the Notebook? In the case of an emergency (e.g. floods, earthquakes, political crisis) it is important to know where the health facilities are located. Furthermore, it is important to identify which cities/districts have a reduced or no access at all to health facilities before an emergency. Many countries still posses…
