Abstract:
The LANDFIRE (LF) 2019 Limited Update (2019L) Fuel Vegetation Type (FVT) represents a modified pre-disturbance version of LF 2016 Remap (LF Remap) Existing Vegetation Type (EVT). FVT leverages fuel transition assignments related to disturbed areas by re-establishing pre-disturbance vegetation. In 2019L FVT was developed using the latest Annual Disturbance products from the effective disturbance years of 2011 to 2019. Fuel products were created with LF Remap vegetation in non-disturbed areas, but pre-disturbance vegetation was used in disturbed areas using fuel rule sets. More information about 2019L can be found at https://landfire.gov/lf_limited.php.
2019L FVT is a capable fuels product that calculates time since disturbance (TSD) assignments for disturbed areas using an effective year. For example, year 2021 fuels may be calculated for the year 2021. This process considers all the existing disturbances and adjusts the TSD for these to the effective year (2021 in this example), making the products "2021 capable fuels." More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php.
Purpose:
LF 2019L is the first update to the LF 2016 Remap conterminous United States (CONUS) extent. This update includes a limited set of products that represent circa 2019 ground conditions. Read more about LF 2019L here (https://landfire.gov/lf_limited.php).
LF 2019L 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.
Supplemental_Information:
In LF 2019L, fuel products were created with LF 2016 Remap vegetation in non-disturbed areas, but pre-disturbance vegetation was used in disturbed areas. This product has 2021 capable fuels functionality.
Order, Class, and Subclass attributes are based on the Federal Geographic Data Committee (FGDC) Vegetation Subcommittee's vegetation classification standard and pertain to upper physiognomic levels of the NVC hierarchy. Order describes the dominant life forms (tree, shrub, dwarf shrub, herbaceous, or nonvascular) within the Vegetated Division of the hierarchy. Class describes the level in the classification hierarchy defined by the relative percent canopy cover of the tree, shrub, dwarf shrub, herb, and nonvascular life form in the uppermost strata during the peak of the growing season. Subclass describes the predominant leaf phenology of classes defined by tree, shrub, or dwarf shrub stratum (evergreen, deciduous, mixed evergreen-deciduous), and the average vegetation height for the herbaceous stratum (tall, medium, short). In addition to physiognomy, a cross-walk based more on the floristic composition of each EVT is provided using the combined classifications of the Society of American Foresters (SAF) and the Society for Range Management (SRM) for forested and rangeland types, respectively. LANDFIRE EVTs that do not apply to these pre-existing categories are cross-walked to coarser, LANDFIRE cover classes.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
For LF 2019L EVT the Auto-Keys process was re-designed. Auto-Keys are used to determine existing vegetation type classification based on plot data in the LF Reference Database (LFRDB). A validation of the EVT product is conducted by comparing the EVT product for a pixel with the Auto-Key EVT assignment for a sample plot contained in that pixel. These agreement assessments have been developed for each LF CONUS GeoArea. To read more about EVT agreement assessments go to https://www.landfire.gov/evt.php
Logical_Consistency_Report:
The products were pixel "truth" tested for consistency of land or water characteristics across all products.
Completeness_Report:
Products were formally tested to ensure that valid data was produced for all pixels. Each product was then validated and tested for duplicates, omissions, and errors.
Lineage:
Process_Step:
Process_Description:
Beginning in 2019 LF 2019L products were created using recent advances in image compositing, tiling algorithms, and faster computing hardware to ensure that LF products remained relevant. LF 2019L leveraged the Landsat archive, lidar data, and user contributed field plot data compiled into the LF Reference Database (LFRDB), to create new base map vegetation products. Reference resources included, but were not limited to, Forest Inventory and Analysis (FIA) program plot data (USFS https://fia.fs.fed.us/), Landsat Dynamic Surface Water Extent [(DSWE) USGS https://www.usgs.gov/core-science-systems/nli/landsat], the National Land Cover Dataset [(NLCD) USGS https://www.mrlc.gov/data], and National Agricultural Statistics Service [(NASS) USDA - https://www.nass.usda.gov/]. To read more about LF reference resources go to https://www.landfire.gov/reference.php. Information about LF 2019L product testing is available by request or via the website at https://www.landfire.gov.
