OpenStreetMap
OpenStreetMap (OSM) is a collaborative, openly licensed geospatial database of the world built and maintained by a global community of contributors. It provides detailed vector data for infrastructure features including building footprints, road networks, waterways, land use, and points of interest. The data is freely available under the Open Database License. The Urban Flooding Open Knowledge Network (UF-OKN) uses OpenStreetMap building footprints and road networks as the urban-infrastructure features that it relates to their nearest river and to the streamflow that would inundate them.
