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 carryout 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.
