Boundary Surveys

A boundary survey is a property survey used to measure the perimeter of any property to locate the boundary line. Only after deciding the boundary, the area of a property can be computed. Bases on the area, the land can be subdivided, sold or any building can be constructed on the land. The property corners are first marked with any type of markers, such as rebar, metal survey markers, pipe, or wooden flags, and are then labeled for identification. The markers should be visible from all sides of the property to ensure optimum visibility. Any paint that assures visibility is used to indicate the boundaries in between the corner points. The procedure of delineating property lines must adhere to legal description and guidelines and it is an important part of the land registration system. This type of surveying is also called cadastral surveying.
