The Specifications in this land surveyor course provide guidance for writing accurate boundary descriptions and locations by survey, the form and arrangement to be followed for Executive and public land orders and proclamations, and examples of boundary descriptions. A boundary is the fixing of a limit or extent of property and, in this publication, is associated with uplands and inland waters and tidelands with application to marine boundaries. The Specifications also provide a standardized process for review of descriptions to assure that only the best available descriptions are published. When an executive department or any agency or establishment of the Federal Government describes or specifies any parcel of land or marine area by boundary or subdivisional unit, the description should be a model of precision, to the extent the available record data permit. A law, regulation, or order cannot fulfill its intent if the boundary description is inaccurate, vague, or ambiguous. This is a 4 hour online continuing education course for Land Surveyors.
