The LANDFIRE National Project (LF_1.0.0) was successfully completed in 2009. The goal of LANDFIRE
National was to generate consistent 2001 vintage 30 meter spatial data sets for all 50 States for fire and
other natural resource applications. This report highlights results from the continuation of LANDFIRE as
a program to update the spatial data layers through 2008. The focus of this phase of the program was
to improve the data products and account for vegetation change across the landscape caused by
wildland fire, fuel and vegetation treatments, and management. In addition, changes caused by insects
and disease, storms, invasive plants, and other natural or anthropogenic events were incorporated
when data were available. This report describes the LANDFIRE 2001/2008 Refresh effort to update
existing map layers to reflect more current conditions, focusing primarily on vegetation changes. The
effort incorporated user feedback and new data, producing two comprehensive Refresh data product
sets:
1. LANDFIRE 2001 Refresh (LF_1.0.5) enhanced LANDFIRE map layers by incorporating
user feedback and additional data to provide a foundation to update data to 2008. It
was also designed to provide users with a data set to help facilitate comparisons
between 2001 and 2008 (i.e. Refresh LF_1.1.0) data sets.
2. LANDFIRE 2008 Refresh (LF_1.1.0) updated map layers to reflect vegetation changes
and disturbances that occurred between 1999 and 2008.
In this report, we (1) address the background and provide details pertaining to why there are two
Refresh data sets, (2) explain the requirements, planning, and procedures behind the completion and
delivery of the updated products for each of the data product sets, (3) show and describe results, and
(4) provide case studies illustrating the performance of LANDFIRE National, LANDFIRE 2001 Refresh and
LANDFIRE 2008 Refresh (LF_1.1.0) data products on some example wildland fires.
