Social media as an information source for rapid flood inundation mapping

During and shortly after a disaster data about the hazard and its consequences are scarce and not readily available. This research proposes a methodology that leverages social media content to support rapid inundation mapping, including inundation extent and water depth in case of floods. The use case in the city of Dresden for the June 2013 flood shows that social media may help to bridge the information gap when traditional data sources are lacking or are sparse.
