The ability to analyze and visualize large amounts
of environmental and hydrological data on maps is difficult.
Interaction and manipulation of data is crucial for decision
making in natural disasters like floods. Hence, we present a
Water Management Application (WMA), a geovisual analytics
application to help analysts explore large amounts of hydrological
data on web-based maps, create early flood warnings, and
make strategic decisions in critical situations. With WMA we
have provided monitoring and management of environmental
resources which can help inform the design of future geospatial
and geovisual analytics applications.
