Non-LANDFIRE Data: California Landscape Data v 082710

Last updated on 8/16/2011 11:40:45 AM.


WFDSS uses the aspect, slope, elevation, fuel model, canopy cover, canopy base height (CBH), canopy bulk density (CBD), and stand height layers to a create landscape file that displays fuels, topography and canopy information simultaneously. Landscape data can be viewed for any point on a map display by clicking the Info sub-tab > selecting the I Icon tool > and then clicking on the landscape. The default Landscape Data Source for incidents is the most current source available, but this can be changed for an incident on the Incident Information tab.

Landscape data in WFDSS is sourced from LANDFIRE and a multi-partner wildland fire and wildland fuel mapping project in the state of California. All values are measured with the metric system:


Unit of Measure







canopy base height


canopy bulk density


canopy cover


stand height


The California landscape 2010 data set is an annual, multi-partner wildland fire and wildland fuel mapping project within the state of California. The California fuels data are supported by the California Fire and Resource Assessment Program (FRAP), US Department of Agriculture (USDA) Forest Service Region 5 Fire and Aviation Management, the US Department of Interior (US DOI) Bureau of Land Management and DOI National Park Service. California fuel data tasks are completed by the USDA Region 5 Remote Sensing Lab.

Non-LANDFIRE Data: California Landscape Data 2010

The California Landscape 2010 fuel data describe the composition and characteristics of both surface and canopy fuel. Specific products include the following:

The California Landscape 2010 is not the same as the LANDFIRE data. These data use the annually updated, comprehensive CALVEG (Classification and Assessment with LANDSATTM of Visible Ecological Groupings) vegetation data ( to classify fuels. The extent of this landscape includes California and some adjacent areas of Nevada, Oregon, and the Californian Islands. Slope, aspect, and elevation are provided by the EROS data center to create a complete landscape file.

Canopy fuel algorithms from the Fire and Fuels Extension of the Forest Vegetation Simulator (FFE-FVS) were used to compute canopy bulk density (CBD), canopy base height (CBH), canopy cover (CC), and canopy height (CH). Areas on U.S. Forest Service lands apply Forest Inventory and Analysis (FIA) plots computed with FFE-FVS. Canopy values are modified based on disturbance severity recorded in the Forest Service Activity Tracking System (FACTS) database. Non-Forest Service areas use values from LANDFIRE National v1.0.0.

Only the 40 fire behavior fuel models (Scott and Burgan 2005) are used in this landscape. Fuel model data were cross-walked from the CalVeg data set (vegetation type, size, density), aspect (wet & dry), and four elevation classes. After assignment, the fuel models may have been modified based on fire history, burn severity, mortality, timber harvesting, or the disturbance severity data from the FACTS database.
