BLM LR2000 mineral material authorizations for the Sagebrush Mineral-Resource Assessment (SaMiRA) aggregated by Public Land Survey System (PLSS) section boundaries and serial numbers

The polygon (vector) shapefiles represent claim areas within Public Land Survey System (PLSS) sections aggregated by serial (claim) numbers with information about Bureau of Land Management (BLM) land and mineral use authorizations mineral materials. The land areas specified by BLM authorizations vary in size and orientation, and may cross one or more PLSS section boundaries. For spatial consistency, the information was aggregated to the square mile PLSS section boundary and by serial numbers. The original source data from BLM Cases Recordation database (LR2000) were specific to the day they were generated (March 6, 2016) and subsequent data pulls will likely be different.
