2. Micro-Topography: LIDAR is very accurate and precise technology which uses laser pulse to strike the object. Regular photogrammetry or other survey technology can miss the surface elevation value that is hidden by vegetation or forest canopy. But LIDAR can penetrate through the object and detect the surface value.
3. Agriculture: LIDAR helps the farmer to find the area that uses costly fertilizer. LIDAR can be used to create elevation map of the farmland that can be converted to create slope and sunlight exposure area map. Both the layer information can be used to create high, medium and low crop production area. Extracted information will help farmer to save on the costly fertilizer.
