How can GIS fit into an E9-1-1 system?
E9-1-1 is a perfect venue for implementing a GIS. In essence, an E9-1-1 system is based on the relationship of points (homes), lines (roads) and polygons (boundaries). The MSAG describes each road in the service area, split into separate segments and defined by address range, for every emergency response zone (polygon). GIS opens many options to 9-1-1 centers including Dispatch Mapping, AVL, Vehicle Routing, Wireless Call Mapping, Automated Emergency Management, Automated Addressing and Map Maintenance and much more.
