The Wildfire Management Tool - Web Edition (WMTweb) is a mobile and desktop compatible web application that displays the potential fire behavior of wildfire on a virtual 3D globe. WMTweb is built on the NASA Web World Wind JavaScript SDK and interfaces with the LANDFIRE, GeoMAC and National Weather Service REST services. WMTweb runs in your browser (Chrome and FireFox). WMTweb displays the potential fire behavior using new symbology -- the "Wildfire Diamond" -- which conveys the fire behavior at the head, flanks and heal. Point weather forecasts are graphically displayed using weather station symbols.
