For conducting topographic surveys, a survey-quality Global Positioning System (GPS) unit and an electronic distance measurement (EDM) total station theodolite (TST) are used to determine the location of the features shown above the plan. A topographic survey shows the existing features, property lines and contour lines that indicate the land levee. We usually get the right amount of land through topographic survey. So there is no substitute for topographic survey.


TOPOGRAPHIC SURVEYS: WHAT YOU NEED TO KNOW?
A topographic or topographical land survey shows the height, depth, size and location of any manmade or natural features on a given parcel of land, as well as the changes or contours in elevation throughout the parcel. While boundary surveys focus on horizontal measurements, topographic surveys are about elevation.
