A topographic survey is a type of land survey that locates all surface features of a property and depicts all natural features and elevations, creating a 3-dimensional map of a 3-dimensional property showing all natural and man-made features and improvements. Topographic surveys are also known as contour surveys and are required by many local government bodies to determine the existing conditions and elevations of a site. They are used by architects and engineers to create accurate and appropriate designs based on existing conditions, and clients can use topographic surveys to determine and plan features such as drainage ditches, grading, or other features, using the natural landscape as the basis for such improvements.
A topographic survey includes elevation changes, terrain levels, and structures on a property for professionals designing construction plans. The maps outline a plot’s key details, including terrain, elevation changes, and existing property features. A licensed land surveyor uses specialized technology to scope out a property’s natural and manmade elements and create a detailed map for developers and designers. Topographic surveys also show existing features, property lines, and contour lines that indicate the lay of the land.
Topographic surveys are used for various purposes, including real estate transactions, civil engineering design, and construction projects. They are also used to determine the locations of features shown on the plan, and to create accurate and appropriate designs based on existing conditions. Topographic surveys can last hours, days, or months, depending on the tasks size and difficulty and how much data will be generated.
