A topographical survey, also known as a topographic survey, is a precise and detailed measurement and mapping process used to determine the physical features and elevation of a piece of land. It identifies both natural features—such as hills, valleys, rivers, and vegetation—and man-made features—such as buildings, roads, utility lines, fences, and drainage systems. The main goal of a topographical survey is to capture the three-dimensional characteristics of the land surface to produce a map or digital model for use in planning, engineering, construction, environmental management, and other applications.
