I am looking for information about data that has wildfires in the United States but I am interested more specifically in Colorado. Do not be confuse with the Forest Fires. How or where do I find the GIS or geospatial data ?
Wildfire Location Data: National Interagency Fire Center (NIFC) supplies the fire data to geomac https://www.nifc.gov/fireInfo/nfn.htm
Office of Wildland Fire funds geomac https://www.doi.gov/wildlandfire
Wildfire - Wildland Fire Information Federal Fire Occurrence Website http://wildfire.cr.usgs.gov/firehistory/data.html
Daily Incident Map http://activefiremaps.fs.fed.us/lg_fire2.php
InciWeb Incident Information System has a lot of fire data, but you can search by wildfire
GeoMAC - existing wildfire situation in continental US and Alaska http://www.geomac.gov/
Boulder has wildfire parameters, boundaries and a few more like that, which aren't live fire data, but you may find useful:
OpenColorado has two more sets from Boulder, not sure but I'm guessing there may be overlap there:
Here's an old Denver wildfire .kml
Virginia's Department of Forestry Wildland Fire, Incident and Suppression Resources, and Wildfire Risk Assessment for the state and regions:
Virginia's Department of Forestry Wildland Fire Incidents Map
MODIS satelitte imagery via NASA
I'm guessing you've already encountered both of these but just in case...
The Monitoring Trends in Burn Severity is a remote sensed product with spatial extent of wild fires: http://www.mtbs.gov/nationalregional/intro.html
The USFS also has a dataset built from the Fire Program Analysis system: http://www.fs.usda.gov/rds/archive/Product/RDS-2013-0009.3/
