Topographic products provide geospatial information describing the landscape of the United States and its territories.
Topographic data serve as input to the Landscape GeoTIFF file which is used in models to predict wildland fire behavior and effects.
Note: Topographic products are rarely updated. The latest version available is the LF 2020 Update (LF 2020). In LF 2020, topographic products were consistently calculated from true north, a correction from earlier topographic products.
