What are BLM Land Descriptions?

The Bureau of Land Management (BLM) maintains the official cadastral survey records for federal lands in the United States. BLM land descriptions use the Public Land Survey System (PLSS) to identify specific parcels of land using townships, ranges, sections, and subdivisions.

Township America uses BLM's Geographic Coordinate Data Base (GCDB) to provide accurate conversions between legal land descriptions and GPS coordinates.
