The program is conducted by the USGS EROS and the USDA Forest Service GTAC. MTBS was first enacted in 2005, primarily to meet the information needs of the WFLC. The primary objective at that time was to provide data to the WFLC for monitoring the effectiveness of the ten-year National Fire Plan. The scope of the program has grown since inception and provides data to a wide range of users. These include national policy-makers such as WFLC and others who are focused on implementing and monitoring national fire management strategies; field management units such as national forests, parks and other federal and tribal lands that benefit from the availability of GIS-ready maps and data; other federal land cover mapping programs such as LANDFIRE which utilizes burn severity data in their own efforts; and academic and agency research entities interested in fire severity data over significant geographic and temporal extents.
MTBS data is freely available to the public and is generated by leveraging government land imaging programs including the Landsat satellite program, jointly developed and managed by the USGS and NASA, and the Sentinel-2 program developed and managed by ESA. Landsat is the primary data source for MTBS. These data points are analyzed through a standardized and consistent methodology, generating products at a 30-meter resolution dating back to 1984. One of the greatest strengths of the program is the consistency of the data products which would be impossible without the historic Landsat archive, the largest in the world.
Sentinel-2 has been providing additional observations of burned areas since 2015, particularly in regions of relatively persistent cloudiness. This increases the opportunity to provide optimal imagery to complete the mapping of MTBS fires that would otherwise go unmapped due to the lack of available quality Landsat observations. The Sentinel-2 data is also analyzed using the same standardized and consistent methodology and is resampled to generate products at 30-meter resolution.
As the MTBS effort continues, new and/or follow on missions with sensors like the current Landsat OLI and Sentinel-2 MSI sensors will be introduced. These missions will be evaluated by the MTBS Program and integrated as needed to ensure extension and continuity of this multidecadal fire mapping report into the future.
