The purpose of topographic surveys is to collect data on natural and man-made features on the ground, as well as its elevation. Topographic maps are used to serve architects, engineers and construction companies in designing and planning works.

​

By always applying the latest surveying technologies, VHS surveyors create highly accurate and reliable products in a short time, helping customers save significant time and money.

 

One of the latest technologies applied at VHS is the use of the LiDAR system installed on manned aircraft to map a large area. This technology is extremely useful for large areas where it is difficult for humans to reach and complete surveys in a short time.

The LiDAR system is a Leica Citymapper-2 which will be mounted on a Cessna 208 aircraft.

 

Our Topographic surveying services are:

• Large area mapping using LiDAR technology.

• Topographic survey on a scale of 1/500, 1/2000.

• Establish the control point system according to TCVN standards.

• Photogrammetry survey by drone.

• Monitoring of movement and deformation of construction such as bridges, high buildings and Wind turbines.
