Free satellite imagery can be used along with free GIS software, or other GIS Software such as ArcGIS, to map the extent of a wildfire with the Difference Normalized Burn Index (dNBR) which is as follows:
dNBR = NBRprefire - NBRpostfire
where, NBR = (NIR - SWIR) / (NIR + SWIR)
(SWIR is band 7 for Landsat 5, 7, and 8; for Sentinel-2, use SWIR Band 12)
Images transition every 4 seconds (or click arrows or dots); description appears below graphic.
(The above graphics show dNBR map and steps for the 2002 Williams and Curve Fires in southern California.)
