  • Mapping Public Urban Green Spaces Based on OpenStreetMap and Sentinel-2 Imagery Using Belief Functions

    Public urban green spaces are important for the urban quality of life. Still, comprehensive open data sets on urban green spaces are not available for most cities. As open and globally available data sets, the potential of Sentinel-2 satellite imagery and OpenStreetMap (OSM) data for urban green space mapping is high but limited due to…

  • Ohsome Green Region of the Month

    Welcome back to the ohsome region of the month format where you can learn and get inspiration about potential applications of the ohsome API. This time we looked at forest-related information in four different Canadian regions looking for the green region of the month, which means there will be a winner announced at the end…

  • Towards a framework for the analysis of local OSM contributions

    Volunteered Geographic  Information (VGI) such as OpenStreetMap (OSM) is often defined as the collaborative acquisition of geographic information and local knowledge by volunteers, amateurs or professionals (Goodchild, 2007).
