The BLM’s Geographic Coordinate Database (GCDB) is the proper representation of the Public Lands Survey System (PLSS) to use as a mapping framework for the many cadastral layers that have a PLSS basis. This presentation describes some tools and methods to integrate legacy GIS data sets to the GCDB, and how to re-adjust GIS layers that are already on the GCDB, when the GCDB is updated or improved. www.djanda.com
