Data Products ›› LANDFIRE National Product Descriptions Forest Canopy Bulk Density
Canopy bulk density (CBD) describes the density of available canopy fuel in a stand. It is defined as the mass of available canopy fuel per canopy volume unit. Geospatial data describing canopy bulk density supplies information for fire behavior models, such as FARSITE (Finney 1998), to determine the initiation and spread characteristics of crown fires across landscapes (VanWagner 1977, 1993). The Canopy Bulk Density layer is generated using a predictive modeling approach that relates Landsat imagery and spatially explicit biophysical gradients to calculated values of CBD from field training sites. Because of model requirements, these data are provided for forested areas only. The units of measurement for the LANDFIRE Canopy Bulk Density layer are kg m-3 * 100.
