Cadastral Surveys

Original survey, resurvey, or retracement of public lands within the Public Land Survey System of the United States for restoration of property lines. Originating with the Land Ordinance of 1785, cadastral surveys create, define, mark, and re-establish the boundaries and subdivisions of the public lands of the United States.  (The word "cadastral" is derived from cadastre, meaning a public record, survey, or map of the value, extent, and ownership of land as a basis of taxation.)  These surveys provide public land managers and the public with essential information needed to correctly determine ownership rights and privileges and facilitate good land management decisions.
