The US National Weather Service has a lot of weather to watch! They have sensors all over the continent, and in space, ranging from simple thermometers to orbiting satellites. When weather happens (and let’s be honest, weather is always happening, it’s happening on me right now) it happens fast — how does the NWS take in the whole situation at a glance and make decisions? On a map, of course.
The NWS Central Region Headquarters has built a test-bed for putting their situational information onto web maps, and the toolset they used is the OpenGeo suite of applications: PostGIS, Geoserver, OpenLayers. They also used raster-data standby GDAL for handling gridded data conversions.
A paper on their work (”Development of Web-based GIS Applications for Decision Support and Situational Awareness“) was presented by Brian Walawender at the American Meteorological Association Annual Meeting this week.
