  • Successful PhD Defense by Amin Mobasheri on OSM quality enrichment for wheelchair routing

    Last Friday Amin Mobasheri of the GIScience Research Group Heidelberg University successfully defended his PhD in Geoinformatics. Due to the Corona pandemy the defense was conducted in hybrid mode with the committee members participating virtually and only Prof. Zipf and Amin being physically in the room. What a shame there was no joint celebration possible…

  • New paper published about the OSM Sketch Map Tool

    The Sketch Map Tool supports participatory mapping approaches and risk communication. An new paper presents the different functionalities of the tool. OSM data quality can be evaluated regarding the fitness for the sketch-map-approach. Based on the great idea of Field Papers, paper maps can be printed out for the use in the field, and afterwards,…

  • Open Data + Open Software – A perfect match

    On 1st March 2021, the Swiss Federal Office of Topography (SwissTopo) released all official geodata according to the principles of “Open Government Data (OGD)”. With this step, Swisstopo is making large volumes of high quality geodata freely accessible. We are most excited about the 3D data, which includes digital surface models, digital terrain models and…

  • Tagging the main entrances of public buildings based on OpenStreetMap and binary imbalanced learning

    Determining the location of a building’s entrance is crucial to location-based services, such as wayfinding for pedestrians. Unfortunately, entrance information is often missing from current mainstream map providers. Frequently, automatic approaches for detecting building entrances are based on street-level images that are not widely available. To address this issue, in a recently published paper in…

  • Press release: Understanding the Spatial and Temporal Dimensions of Landscape Dynamics

    The research of the 3DGeo group is featured in a press release about Understanding the Spatial and Temporal Dimensions of Landscape Dynamics. The text illustrates how Heidelberg geoinformation scientists develop new computer-based method to analyse topographic changes. The described method is published in this article: Anders, K., Winiwarter, L., Mara, H., Lindenbergh, R., Vos, S.…
