LiDAR Data Processing
LiDAR is a remote sensing technology that stands for Light Detection And Ranging. Lidar technology measures distance by illuminating a target with a laser and analyzing the reflected light. It functions similar to the Sonar technology used by fish to detect objects in the water and which humans use in boats to find objects or depth in water. Airplanes and helicopters are the most commonly used platforms for acquiring Lidar data over a large area. There are three main types of Lidar such as Airborne Lidar, Mobile Lidar and Terrestrial Lidar.

Airborne LiDAR Data Processing
This is the most commonly used technique for land mapping which uses point cloud data acquired from airplanes along with the images to create 3D maps.
Mobile LiDAR Data Processing
This technique is typically used to create maps for street views or building numbers collection where the sensor is mounted on top of a car as it drives through the streets capturing data along the way.
Terrestrial LiDAR Data Processing
This technique is typically used to map hill slopes or buildings or monuments where the sensor is stationary, usually placed at the center of the object, and the rays are bounced off to get a point cloud data which is then used to create a 3D view of the object.
