Topographic surveys establish the different manmade and the natural features of land. This type of survey can be very beneficial to property owners. Land may include hills, trees, fences, buildings, ravines. A topographical survey will provide exact figures of the size, height and position of different changes that have occurred over the course of time with regard to their presence or that of any man made structures.
Many construction projects include a topographic survey in the early planning stages, because engineers and architects refer to the topographic information during site and structural design. Landscape architects and planners use topographic surveys for the formulation of an optimal plan for drainage, grading and other features.
