The reason topographic surveys are performed is to test the characteristics of the land surface such as relief, natural features and even man-made features. Relief includes natural features such as hills and valleys as well as plains, natural features includes such things as trees and waterways, and man-made features will include roadways, buildings and other man-made objects.The topographic survey is performed in order that a topographic map can be produced and this map simply displays the natural and artificial features of an area. This map can be presented in 2D plans of the site or 3D models of the site overlaid with Land Registry and Title Deeds. There are many reasons why you would want topographic surveys done. Buyers of land, engineers and architects all regularly need to have topographic surveys done at some point. When you are designing a building it is very important to have one done as the features of the land on the site where the building is to be built will have an impact on the design of the building. In addition if you are buying land it would be very advisable to have a topographic survey done before deciding what the best use of the land.
