what is a topographical survey

A topographic survey is a type of land survey that gathers data about the natural and man-made features of the land, as well as its terrain. The survey maps out a propertys key details, including terrain, elevation changes, and existing property features. It is essentially a 3-dimensional map of a 3-dimensional property showing all natural and man-made features and improvements. The survey is conducted by a licensed land surveyor using specialized technology to scope out a propertys natural and man-made elements and create a detailed map for developers and designers. The survey includes elevation changes, terrain levels, and structures on a property for professionals designing construction plans. Topographic surveys 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. The survey shows existing features, property lines, and contour lines that indicate the lay of the land. The results of the topographic survey are presented as contour lines on a site map, and can be enhanced by computer software to provide interactive views. Topographic surveys are used for a variety of purposes, including real estate transactions, civil engineering design, and construction projects.
