LiDAR (Light Detection and Ranging) Survey aids in Geo-referencing, Topographical Mapping and Image Processing which constitutes as integral components of modern geospatial data collection and analysis. It is a remote sensing technology that uses laser pulses to measure distances to the Earth's surface.
- i. LiDAR sensors emit laser beams towards the ground and the time it takes for the laser pulses to return is used to calculate the distance to objects on the Earth's surface.
- ii. LiDAR surveys can create highly detailed 3D maps of terrain, vegetation, buildings and other features by collecting millions of these distance measurements.
- iii. LiDAR data is utilized in various applications which includes forestry, urban planning, flood risk assessment, infrastructure planning and natural resource management.
