Introduction to Topographic Survey
Topographic survey involves determining the horizontal and vertical locations of objects on the surface of the earth. Horizontal location entails locating ‘objects’ like roads, railways, ponds, houses, boundaries of properties, etc. by measuring horizontal distances; the objects are indicated by symbols. Vertical location includes the location of hills, valleys, depressions, benchmarks, RLs of points, etc. by measuring vertical distances; the objects in this case are represented in relief.Thus, a topographic map shows the nature of the earth surface along with the positions of different objects. Such a map is essential for the engineering projects involving roads, railways, irrigation, reservoirs, townships etc. The scale of a topographic map depends on the extent of area it covers, and the purpose for which it is to be prepared. Generally topographic map is prepared according to a scale of 1 cm to 1 km (i.e. 1/100,000).
The primary goal of topographic surveys
The primary objective for Topographic Survey is to produce a three-dimensional drawing of a particular piece of land or area. Our Topographical Surveys include all-natural and man-made features which are represented by text, lines, and symbols on the drawing. The drawing of the topographic survey also includes heights and elevations which are represented by spot levels and contours for the execution of engineering projects, GeoTRAK carried out a Topographical Survey of Clients like CTCI Taiwan, TATA- Aldesa, Reliance, and companies all across India.
Most Commonly topographical surveys are used for the planning stages of different projects to help design the layout and location. Our team of experienced professionals has the capability of handling combinations of topographic maps, which makes us deliver accurate results on time..
