Jon Dewitz 20250930 LF 2001 raster digital data Sioux Falls, SD Earth Resources Observation and Science Center (EROS), U.S. Geological Survey https://doi.org/10.5066/P13KXTGM https://www.landfire.gov Jennifer L. Long Timothy D. Hatten 2023 publication n/a US Geological Survey https://doi.org/10.3133/fs20233044 The LANDFIRE Annual Disturbance products for 1999-2007 are included within the LF 2001 version and are developed through a multistep process. Inputs to this process include (but are not limited to): Landsat imagery derived Normalized Burn Ratio (NBR) data (in CONUS only), polygon data developed by local agencies, fire data obtained from Monitoring Trends in Burn Severity (MTBS), Burned Area Reflectance Classification (BARC), and Rapid Assessment of Vegetation Condition after Wildfire (RAVG) fire mapping efforts, and Protected Area Database (PAD) data. Event polygon data are provided to LANDFIRE by various local, regional, and national agencies and organizations. Disturbance type and year information is included as attributes for each polygon and transferred to the disturbance grids. Severity is determined by using dNBR (difference Normalized Burn Ratio) data classified into high, medium, and low severity levels based on a statistical comparison with the MTBS, BARC, and RAVG fire severity. Vegetation Tracker (VCT, Huang, et. al. 2008) algorithms are used to identify disturbances outside of LF 2001 Events. VCT data are developed for each year identifying disturbed areas and severity. Since disturbance type (i.e. causality) is not determined in the VCT process, a spatial analysis was done comparing the VCT output to buffered (1 kilometer) LF 2001 Events and PAD GAP land use characteristics. While not providing a precise type of disturbance, this analysis provides information useful for narrowing down the types of disturbance that could or could not typically occur. Each zone has ten disturbance grids, one for each year 1999 to 2007. Each grid is attributed with year, disturbance type (if known, otherwise a description of possible types), severity, and the data sources used to create the data. The LANDFIRE (LF) 2001 (version 1.0.5) Refresh of the LF National Base Map is the foundational version of LANDFIRE. The initial data released by LANDFIRE, referred to as LANDFIRE (LF) National (version 1.0.0), was completed in the winter of 2010. LF 2001 released in 2011 and incorporated improvements as well as remodeled cover and height layers. LF 2001 also ensured wildland fires through 2001 were represented. When LF 2001 released, it superseded LF National as the revised base map. LF 2001 products are designed to facilitate national and regional level strategic fire and resource management planning and reporting of management activities. The principal purposes of the products include providing: 1) national level landscape scale geospatial products to support fire and fuels management planning and 2) consistent fuels products to support fire planning, analysis, and budgeting to evaluate fire management alternatives. Products are created at a 30-meter raster; however, the applicability of products varies by location and specific use. LF products were designed to support 1) national (all states) strategic planning, 2) regional (single large states or groups of smaller states), and 3) strategic/tactical planning for large sub regional landscapes and Fire Management Units (FMUs) (such as significant portions of states or multiple federal administrative entities). The applicability of LF products to support fire and land management planning on smaller areas will vary by product, location, and specific use. Managers and planners must evaluate LF products according to the scale and requirements specific to their needs. 2004 ground condition Complete None planned -127.9878 -65.2544 51.6497 22.7654 ISO 19115 Topic Category imageryBaseMapsEarthCover biota None raster digital data U.S. Geological Survey (USGS) U.S. Forest Service (USFS) LANDFIRE 2001 LF 2001 Annual Disturbance 2004 Dist annual disturbance yearly disturbance USGS Thesaurus fire hazard preparedness remote sensing image collections geospatial datasets geographic information systems USGS Metadata Identifier USGS:68d1c536d4be0223c91d695e Common geographic areas US CONUS United States Conterminous United States Continental U.S. None These data are marked with a Creative Common CC0 1.0 Universal License.
