Topographic Surveys

Topographic Surveys

Topographic surveys establish the different manmade and the natural features of land.
This type of survey can be very beneficial to home owners, industrial owners, or even for properties under construction. 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.

Topographical surveys are also referred as contour surveys and are conducted before a change in property ownership takes place or before an owner makes changes to land or existing property. The main focus of topographical surveys is – on the distance from the ground rather than the horizontal measurements. Horizontal measurements are provided with an in-depth focus on boundary and residential surveys.

In topographical surveys, most of the measurements are done with a high quality GPS unit or with a electronic EDM instruments (that measure distance with the usage of light and radio waves). The results of the survey are presented in the form of contour lines on maps of the land; unlike in other types of surveys where the results are marked using stakes or other landmarks.

There are many uses for a topographic land survey. Engineers and architects can use the survey results for designing buildings and other improvements. In some cases, they are also used by the Government. Most of the construction projects typically begin with a topographic survey as it provides the framework of the land before improvements are made. Sometimes, a topographical survey is used for the formulation of an optimal plan for drainage ditches, grading and other features. Thus, the results of the topographical surveys i.e.; the natural landscape serve as the basis for the formulation of optimal plans. The results render all the minute details like the elevation of slopes which may be useful figures particularly if you are intending to build on the land. In addition, to the provision of data for developments of undeveloped surveys; they also provide appropriate information for the area that is been previously used.
