  • A discussion of crowdsourced geographic information initiatives and big Earth observation data architectures for land-use and land-cover monitoring

    The effective monitoring of land-use and land-cover changes (LULCC) is a basic requirement for understanding socio-enviromental processes of local to global scales. Remote sensing data and methods have long been established as the most effective approach for monitoring LULCC. The potential for further increasing the effectiveness of this approach is proportional to the astonishingly large…

  • 3D micro-mapping: Towards assessing the quality of crowdsourcing to support 3D point cloud analysis

    Crowdsourcing has been widely applied to extract information from 2D geodata sources such as satellite imagery. In this new study published in the ISPRS Journal of Photogrammetry and Remote Sensing we apply this technique to the growing field of 3D point cloud analysis. This work has been conducted in our 3D-MAPP Project which was funded…

  • Maptember in Ottawa: HeiGIT/GIScience at Missing Maps and HOT gatherings

    This year the capital of Canada will become the gathering place for the Humanitarian OpenStreetMap Team (HOT) and Missing Maps community and partners. September 12th/13th the Missing Maps members will come together for their annual meeting to discuss current projects, challenges, ideas and future plans. The next two days, September 14th/15th, the HOT Summit will…

  • Call For Participation for Crowdsourced Damage Assessment Project

    In the aftermath of a disaster, knowing the condition of buildings, infrastructure, and utilities is critical to both immediate response and long-term recovery efforts. The Humanitarian OpenStreetMap Team (HOT) is often asked to help identify damage to buildings and other assets in the affected region. In the past, limitations in post-disaster imagery and difficulties in…

  • Interview on Crowdsourcing for Optimized Cycle Routes

    On the occasion of the international Bike2Work Day the radio Berlin Brandenburg (RBB) conducted a short interview with Prof. Alexander Zipf (GIScience HD/ HeiGIT). It was about current research and development work at the GIScience Research Group Heidelberg and HeiGIT, which involve the use of user-generated geodata for investigations between cycling behaviour and health, as well as…

  • 3D-MAPP talk at 9th “Dresdner Flächennutzungsymposium”

    The “Dresdner Flächennutzungssymposium” is an annual event aimed at fostering the discussions about current devolepment regarding land use changes in Germany. During two days experts from government agencies, private companies and research institutions come together and elaborate the latest trends in different session. This years symposium took place from May 3-4. Almost all presentations covered…

  • Monitoring and Assessing Post-Disaster Tourism Recovery Using Geotagged Social Media Data

    Tourism is a economically highly important industry. It is, however, vulnerable to disaster events. Geotagged social media data, as one of the forms of volunteered geographic information (VGI), has been widely explored to support the prevention, preparation, and response phases of disaster management, while little effort has been put on the recovery phase. A recently…

  • GIScience support for Crowdsourced Damage Assessment project at Stanford University

    In the aftermath of natural disasters an assessment of the impact and damage in the affected area is crucial to enable coordination of response and recovery. While the disaster preparedness and response activations by the Humanitarian OpenStreetMap Team in regard to infrastructure mapping have already proven great potential in various disaster events, due to a…
