The land survey that locates all-natural, man-made, and topographical features on a piece of property such as elevations of land, trees, buildings, roads, streets, fences, land contours, manholes, trees, rivers, streams, and many more is called a topographic survey.

At Kongunadu Surveyor, we understand the main two purposes of a topographical survey-

Plane Surveying: We achieve this by measuring the horizontal distances and horizontal angles or directions and make plans or maps of an area that show the main physical features on the ground, such as rivers, lakes, reservoirs, roads, forests, large rocks, and the various features of the ponds, dams, lakes, drainage ditches or sources of water.

Direct leveling: We get it done by measuring horizontal distances and height differences called vertical relief such as valleys, plains, hills, or slopes.

In the construction industry, when the land poses noticeable challenges, such as existing man-made structures, steep valleys, or hills leftover from a previous construction project, topographic surveys become essential.

For engineers, a topographical survey is always a big help when ascertaining the changes that need to be made to a piece of land before commencing a construction project. It is common for an architect to make use of a topographic survey as the structure for developing a blueprint of a 3D version of a building project.

Kongunadu Surveyors employ Robotic total station instruments to detail features on-site and all survey points are measured by instruments with an onboard feature code list. Most of the topographic surveys are being done by photogrammetric processes where images are identified by taking control and positioning details on the ground. In harbors or coastal areas, it is essential for the reference system of the topographic survey to coordinate with the geodetic control and with the navigation aids like reference stations, lights, beacons, etc.

We determine costs based on the time we spend on the project and the time is calculated based on the dimensions of the site area, terrain, and visibility. The duration of a topographic survey process depends on the complexity of the terrain surveyed and the size of the area covered. A professional topographic survey, be it a Mortgage survey, Construction survey, Hydrographic survey, Geodetic survey, or Wetland delineation, our experienced team at Kongunadu Surveyor is just a phone call away.

“Topography is like an emotion, with peaks and valleys, plains and crescendo, only that it can be measured.”
