Does the spatiotemporal distribution of tweets match the spatiotemporal distribution of flood phenomena? A study about the River Elbe Flood in June 2013
(The Pennsylvania State UniversityUniversity ParkPennsylvania, 2014-05-18)
In this paper we present a new approach to enhance information extraction from social media that relies upon
the geographical relations between twitter data and flood phenomena. We use specific geographical features like ...
AGORA-GeoDash: a geosensor dashboard for real-time flood risk monitoring
(The Pennsylvania State UniversityUniversity ParkPennsylvania, 2014-05-18)
Flood management is an important approach to reduce damage caused by floods. In this context, technological
