The Geospatial Multi-Agency Coordination Group, or GeoMAC, is an internet-based mapping tool originally designed for fire managers to access online maps of current fire locations and perimeters in the conterminous 48 states and Alaska. Perimeters are submitted to GeoMAC by field offices and then posted to an FTP site for downloading. This file contains fire perimeters submitted from the year 2001 to 2009. The projection is geographic and the datum is NAD83. Last updated in November, 2010.
