Light Detection and Ranging (LiDAR) :

1. Scan the terrestrial surfaces in high resolution
2. Capable of making centimeter-level accuracy distance measurements
3. Produce accurate digital terrain models (DTM) of the earth’s surface
4. Produce million of x, y ,z point cloud
5. Derive contours straight from LIDAR surface
6. Produce Digital Elevation Model (DEM)
7. Generate data into Three Dimension, 3D Information
8. Save time and cost.
