Light Detection and Ranging (LiDAR) systems generate accurate height data and intensity images with the aid of IMU and GPS data, which help to model the earth’s surface in detail. It is a highly accurate and cost effective application.

TGG offers skilled LiDAR data processing, extracting accurate height models in the form of Digital Terrain Models (DTM) and Digital Surface Models (DSM). Our LiDAR services are useful in Cut and Fill calculations for engineering projects like dams, tunnels and roads modeling systems like oil and gas pipelines for maintenance and status evaluation. For forestry applications, LiDAR Mapping, unlike RADAR, with its vegetation penetration properties, is a precise tool for measuring topography, vegetation height and cover as well as complex canopy attributes.

LiDAR outsourcing services of TGG offers you high quality outputs and helps you leverage your operational efficiency.

We are classifying raw data into ground, low, air, vegetation, building, wire, electric tower and water class by using automatic macros. Then we have a detailed quality check by our experienced staffs.
