  • Rapid Assessment of Vegetation Condition: Fire Perimeter Boundaries (Feature Layer)

    Metadata Updated: January 6, 2021

    The USDA Forest Service Rapid Assessment of Vegetation Condition after Wildfire (RAVG) program produces geospatial data and maps of post-fire vegetation condition using standardized change detection methods based on Landsat or similar multispectral satellite imagery. RAVG data products characterize vegetation condition within a fire perimeter, and include estimates of percent change in basal area (BA), percent change in canopy cover (CC), and a standardized composite burn index (CBI). Standard thematic products include 7-class percent change in basal area (BA-7), 5-class percent change in canopy cover (CC-5), and 4-class CBI (CBI-4). Contingent upon the availability of suitable imagery, RAVG products are prepared for all wildland fires reported within the conterminous United States (CONUS) that include at least 1000 acres of forested National Forest System (NFS) land (500 acres for Regions 8 and 9 as of 2016). Data for individual fires are typically made available within 45 days after fire containment ('initial assessments'). Late-season fires, however, may be deferred until the following spring or summer ('extended assessments'). National mosaics of each thematic product are prepared annually. This map service includes perimeters for fires that burned during calendar years 2013 through 2017, excluding late-season 2017 fires that will be completed as extended assessments. The associated raster products (BA-7, CC-5 and CBI-4) are available via the Raster Data Warehouse (RDW, see https://apps.fs.usda.gov/arcx/rest/services/RDW_Wildfire).
