OSPREY - Operational Situational Picture for Response to an Emergency

OSPREY is a Web mapping application that provides useful and freely available geographic data to the public in the event of an emergency. The system compiles data from many sources to give a composite picture of Maryland-specific data and hazard-related information. OSPREY was developed by the Center for GIS at Towson University. OSPREY was built using ArcGIS API for Flex (Environmental Systems Research Institute).

Flood Prone Zones Tool

Maryland is subject to flooding from several different sources. Flash floods tend to come after short periods of heavy rain and most often affect small streams and creeks. General flooding comes from more prolonged steady rain and tends to affect larger streams and rivers. Major rivers such as the Potomac and Susquehanna often reach flood stages because of events in distant areas of their watershed. Finally, hurricanes and tropical storms can cause surges that create tidal flooding along Maryland’s bays and their tributaries.
