A topographic survey is a detailed mapping process that captures the three-dimensional features of a specific area. It includes information about the terrain's elevation, contours, and natural and man-made features such as roads, buildings, and trees. This data is essential for various applications, including construction, land development, and environmental studies. Surveyors use specialized equipment like theodolites and GPS technology to gather accurate measurements. The resulting maps help architects, engineers, and planners understand the landscape, allowing them to make informed decisions about design and land use.
