Fire season always has me scouring the web for satellite fire map information. Unfortunately many of the locations I find are outdated or not maintained well. What would be the best site to go to for the most timely fire data?
There's the "Active Fire Perimeters" service on arcgis.com: http://www.arcgis.com/home/item.html?id=6940c058e2bf49b6a14a6e625df81216
Finally, NIFC is a good provider of up to date info although I don't know of anything they provide that is readily usable by a GIS (but I haven't look too hard either): http://www.nifc.gov/fire_info/nfn.htm
The active fire map data from the forest service is up-to-date remote sensed data: Active Fire Mapping Program
They have the data available in KML among other formats.
Also check out the MODIS subsets at:
Or you can download near-realtime hot-spots from FIRMS:
