What is it?
The National Society of Professional Surveyors describes a boundary, or cadastral, survey as a type of survey performed in order to measure, mark, and map the boundary lines of land ownership. These surveys retrace deeds and other public records to verify the measurements of a piece of property for which the original survey could date back hundreds of years. A boundary survey
may also show any easements, rights-of-way, or other encumbrances on a piece of property.
