OpenFloodRiskMap Online combines Critical Infrastructure from OSM with Emergency Routing

some time ago we deployed OpenFloodRiskMap (OFRM) at

OpenFloodRiskMap (OFRM) is a prototype web application to assist decision makers in developing alarm and operation plans for flood risk management. The OFRM hereby provides support in accessing critical infrastructure (CI) information in the OpenStreetMap (OSM) data base and to furthermore add this information to an emergency routing service based on OpenRouteService.
In a disaster scenario decision makers need to be able to identify asset types of critical infrastructures as these objects are of specific interest for the community and thus, deserve special attention. While there are various frameworks containing definitions and categorizations regarding this concept, these documents do not contain object type catalogues listing these infrastructures on an object level. For this purpose, a catalogue of asset types of CI was already developed by Herfort et al. (Herfort, Eckle, Porto de Albuquerque, Zipf, 2015). In the OFRM, this catalogue serves as a preselection that enables identifying CI in OSM. In a flood scenario, decision makers have to moreover navigate to the CI objects, e.g. for evacuation or to provide security measures, while considering flood related road conditions. This kind of information cannot be considered in a general navigation system, nor can these systems detect CI objects.

Therfore ORS provides some specific functionality, such as:
– List of critical objects in OSM, sorted according to critical sector
– Print function for field use
– Direct transfer of critical objects to emergency routing query
– OSM Id editor link: editing of object in OSM data base
– Storage function for further use of query
– Define areas to avoid in routing through
…. a) Individual area, specified by user with drawing too
…. b) Integrated Flood Hazard Map layer to assist identifying bypass areas


The work has been funded though the Landesanstalt für Umwelt, Messungen und Naturschutz Baden-Württemberg (LUBW) within the “Klimopass” program.
