Topographic surveys are surveys intended primarily to show the relief, or change
in elevation of an area of land. Topographic surveys also usually show other planometric features, such as
buildings, paved surfaces, located utilities, and distinct changes in the surface of the land.
Topographic surveys are commonly used in the early stages of planning for major property
improvements, or for changes in the landscape that may impact drainage or water flow. Topographic surveys can
also be used to calculate volumes of earth in advance or following significant earthwork.
