BLM Cadastral Survey, the FGDC Cadastral Subcommittee, Premier Data Services, and Fairview Industries, have teamed over the past four years to complete the standardized PLSS data for nearly all of the 30 Public Domain states. Oklahoma is the only state waiting to be completed and it is in process. These data sets represent about 40 million parcels that provide the basis for parcel mapping, land governance decisions, and navigation of cadastral data in Public Domain states.
The catalog listing the location of available standardized PLSS data sets which are hosted by BLM and states is available through the Geospatial Platform. The catalog can be accessed at: http://www.geoplatform.gov/node/243/84324aed-78c1-4801-99e3-1ac6c00a3a84
