Lidar Data Processing

LiDAR is a technology that uses a laser scanner mounted in an aircraft to actively scan the terrain below.Light Detection and Ranging (LiDAR) 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.


NST has state-of-the-art technology for carrying out airborne LIDAR data processing and classification for DEM / contour generation. NST in association with their partner's instrumentation facilities and with its core strength of LIDAR planning & processing can carry out complete production cycle of airborne LIDAR data acquisition.


NST has the complete understanding of LAS format and has developed custom built utilities for easy classification of LIDAR points. Navayuga has processed LIDAR Data for more than 4000 Sq.Km around the World.

NST's general LIDAR services include :

GPS-IMU processing for estimation of smooth flight trajectories;

Consulting for Flight Planning Support; Pre processing of raw LIDAR data to derive the point clouds in LAS format or other industry standard format.

GPS Processing for static & Kinematic Surveys

Classification of LIDAR points into Ground, vegetation, building etc; Generating    contours/ orthoimages from LIDAR derived DEM
