A topographical survey will present accurate figures of the size, height and position of diverse changes that have occurred over the course of time with observes to their occurrence or that of any manmade formations. Topographic Surveys requires regulation to which ground contours are related, information regarding surface and underground benefits, establishing required setbacks, etc. The main meeting point of topographical surveys is – on the expanse from the ground rather than the horizontal measurements. Horizontal measurements are provided with an in-depth main point on boundary and residential surveys.

The purpose of topographic survey is data about the natural and man-made features of the land, as well as its distance from the ground. From this information a three-dimensional map may be set. After assembling the field data or prepare it right away in the field by plane table. Topographic surveys are commonly identified with horizontal and/or vertical control of third-and lower-order accuracies. Topographic surveys created the different artificial and the natural features of land. Topographical surveys are also referred as contour surveys and takes place before a change in possession of property takes place or before an owner does changes to land.

In topographical surveys, most of the measurements are prepared with a high speed GPS unit or with a electronic EDM tools (that measure space with the use of light and radio waves). The outcome of the survey are presented in the form of contour lines on maps of the land; while in other types of surveys the results are marked using stakes or other landmarks. Topographical surveys are surveys that show all the physical quality of a territory. They can also have contouring shown. When contouring is shown it permits the user to determine drainage and/or run-off of the site. These surveys are usually used by architects, engineers and managers to plan for areas of future development.

There are various uses for a topographic land survey. Architects and engineers can use the survey results for designing buildings. In some circumstances, they are also used by the Government. Almost all construction projects starts with a topographic survey as it provides the structure of the land before further steps takes place. Sometimes, this survey is used for the planning for drainage ditches, grading and other features. Thus, the outcomes of surveys i.e.; the natural landscape serve as the base for the thinking of optimal plans. The results deliver all the minute facts like the elevation of slopes which may be valuable figures mainly if you are planning to build on the land. Additionally, the provision of data for developments of undeveloped surveys; they also gives proper information for the area that is in earlier times used.
