LANDFIRE 2020 Slope Degree (SlpD) AK
In late 2021 the LANDFIRE (LF) team responded to feedback and created new topographic products (Elevation, Slope, and Aspect) for the Conterminous US, Alaska, Hawaii, and Puerto Rico and the Virgin Islands to release in early 2022. After the DEM was projected to Albers (see DEM metadata abstract), slope (both degree and percent rise) was calculated using the geodesic option in ArcGIS Desktop 10.6.1. The file was then converted to Unsigned 16-bit using the Copy Raster tool in ArcGIS Desktop 10.6.1 and then clipped to the LF boundary using the Extract by Mask tool in ArcGIS Desktop 10.6.1. Percent slope values above 400 were reclassified to 400. Several NoData areas were assigned value zero (0) that overlap the LF data extent which includes a 3 nautical mile buffer along coastal areas. 65535 indicates NoData.
