Product Release – LANDFIRE Remap for Northwest U.S.

The first LANDFIRE base map LANDFIRE (LF) National product suite was developed using data circa 2001. Landscape change never ceases, and although LF National products were updated regularly, the base map is more than 15 years old.
To ensure the data remain relevant, LF is developing a new base map product suite that will represent 2016 ground conditions. Called LANDFIRE Remap, this effort is designed to produce vegetation and fuels data that inform wildland fire and ecological decision systems and will be released incrementally starting in January 2019 through 2020, beginning with the Northwest region of the U.S. (See release schedule) DUE TO GOVERNMENT SHUTDOWN, THE JANUARY NW REGION DATA RELEASE MAY BE DELAYED.

The LF program’s consistent methodologies and processes incorporate current satellite imagery, contemporary data sources, and the latest software and hardware technologies to produce products that will offer significant improvements to all previous LF versions.

LF Remap changes include having unlimited, free access to the Landsat archive which allows for better base imagery (reduced clouds, fewer seamlines, better map masks, better modeling masks), improved plot selection, structure input information, continuous canopy structure, and flexible vegetation type legends based on data driven range maps and ecoregions.

Additional enhancements in LF Remap consist of unprecedented access to the best field data with the Bureau of Land Management for Assessment, Inventory, and Monitoring plots and the Natural Resources Conservation Service for National Resources Inventory plots primarily in non-forest areas. Other changes are new and improved Auto-Keys, Existing Vegetation mapping image classification based on Omernik III/IV Ecoregions (instead of National Land Cover Database map zones), and expert review and feedback.

New products you’ll see in LF Remap are Historical Disturbance (uses the latest 10 years of disturbance data representing disturbance year and original disturbance code), National Vegetation Classification (allows opportunities to evaluate the vegetation classification and mapped products), and Fuel Vegetation Cover, Height, and Type (more accurately leverages fuel transition assignments related to disturbed areas by re-establishing pre-disturbance vegetation type, and binned cover and height products).
