Pin2Flood
First responders can create and share real-time flood maps
What is Pin2Flood?
Pin2Flood is a web-based app which allows the on-scene first responder to make their own flood maps - on demand! By clicking on the mobile app, while standing at water's edge (dropping a 'pin'), the map automatically retruns the boundary of the flood waters, along with identifying impacted address points and roadways.
Pin2Flood is currently two apps - one for field responders (pin drop, flood extent) and one for emergency managers (pins, flood extent, export). With both apps simultaneously displaying the same data, the result is a common operating picture with real-time flood impact maps.
What is the science behind it?
The general concept of HAND (height above nearest drainage or waterway) is simple - it is elevation contours based on the stream bed elevation rather than on sea level. HAND provides a 'topographic map' of water coverage at 1 foot depth increments. When a first responder drops a pin at water's edge, the system looks up the closest HAND contour at that location and immediately displays the flood inundation. While the math to generate HAND is complicated, the results are quick and easy to use.
Pin2Flood not only provides the current boundary of the flood based on a pin drop at waters edge, but it also provides a common language to work from.
