LANDFIRE-Fuel Product Descriptions

The Fuel Characteristic Classification System Fuelbeds (FCCS) layer describes the physical characteristics of a relatively uniform unit on a landscape that represents a distinct fire environment. FCCS provides standardized descriptions of fuelbeds and fire hazard. The system is designed to provide land managers, regulators, and scientists with a nationally consistent and durable procedure to characterize and classify fuel.

FCCS facilitates the mapping of fuel characteristics and fire hazard assessments, and landscape level spatial fire effects simulations. The FCCS layer can serve as input to wildland fire effects models.

Attribute Table

Attribute tables for LANDFIRE grid data are available on the Data Distribution Site. Generally, these attribute tables provide information pertaining to the grid class value along with class descriptions or labels for these values. Attribute tables, such as the Existing Vegetation Type, provide additional attribute fields that can provide crosswalk links to other classification themes. Color mapping fields are also provided within the attribute tables, providing a standardized, consistent LANDFIRE color mapping schema for these data layers. The attribute files are in comma separated value (csv) format that can be easily converted to other formats to meet user needs.

The attribute tables are provided as a convenience as calculations with grid data will automatically drop attributes. For example, if a grid is clipped, the rowid, value, and count are the only attributes retained. Attribute fields can be reattached to the grid using a join attribute function having the "value" attribute as the link.
