Other RAVG Data Access Methods
Annual raster mosaics and combined perimeter shapefiles are available as map services and downloads for recent years. There are three thematic burn severity products (raster datasets) for each year: 7-class percent change in basal area (BA-7), 5-class percent change in canopy cover (CC-5), and 4-class composite burn index (CBI-4). The vector datasets include the perimeters of each fire as mapped for the RAVG program. The fire name, ID, and size (acres) are included as attributes in the perimeter dataset. The assessment type (initial or extended) is included in the downloadable version.
- Raster map services (national mosaics of BA-7, CC-5 and CBI-4)
- Vector map service (burned area perimeters, as mapped)
- Downloadable raster data (national mosaics of BA-7, CC-5 and CBI-4, by year)
- Downloadable perimeters (combined shapefile; search for keyword "RAVG")
Note: Annual national datasets are typically prepared soon after the end of the year. Data for fires processed as extended assessments are added after the following growing season. Raster and vector datasets are updated separately. If they appear to be out of sync, please check back in a few days or send an email message to SM.FS.PostFireRAVG@usda.gov.
Burn Severity Portal
The Burn Severity Portal (BSP) provides access to RAVG data from GTAC (primarily U.S. Forest Service lands) and USGS EROS (primarily Department of the Interior lands) and other post-fire data (e.g., MTBS data). The BSP's interactive viewer allows the user to locate and select data using spatial and temporal filters and download multiple data bundles simultaneously. Note that the addition of USFS RAVG data is underway but not yet complete.
Raster Data Extraction Tool (*Updated December 2021*)
The RAVG Data Extract Tool is an ArcGIS Online (AGOL) application that allows the user to extract ("clip and ship") RAVG thematic data from national mosaics by either a predefined area (e.g., a National Forest) or a user-drawn polygon.
