Modernization of cadastral surveying in the BLM for creation of a comprehensive LIS in the United States
Parker, James M. & Buhler, Donald A.
With abstracts in English, German and French.
Advances in surveying and computer technologies have been integrated into the National Public Land Survey System (PLSS) of the United States by the Bureau of Land Management (BLM). The results of these progressive applications are now being utilized to formulate one data layer, a geographic coordinate data base (GCDB), of a comprehensive parcel-based Land Information System (LIS) for public lands in the United States. A critical part of this component is the use of the official U.S. Cadastral Survey grid, with its corner monuments tied to geodetic coordinates, as the reference framework for tying land ownership and use, as well as resource and cultural features, to their actual location on the ground. The PLSS/GCDB is being designed to meet the future needs of not only BLM but also other federal agencies and to provide the foundation on which state and local governments can build their own parcel-based Land Information Systems.
