LiDAR Spatial Data Analysis

Feiyan Technology focus on offerring high efficient LiDAR data processing service with Lidar aerial photography and other data. Lidar, which stands for Light Detection and Ranging, is a remote sensing method that we use light in the form of a pulsed laser to measure variable distances ranges to the Earth. These light pulses—combined with other data recorded by the airborne system-generate precise, 3D information about the shape and surface characteristics of the Earth.

A LiDAR instrument principally consists of a laser, a scanner, and a specialized GPS receiver. Airplanes and helicopters are the most commonly used platforms for acquiring lidar data over broad areas. Two types of lidar are topographic and bathymetric. Topographic lidar typically uses a near-infrared laser to map the land, while bathymetric lidar uses water-penetrating green light to also measure seafloor and riverbed elevations.

After the LiDAR mapping is done, we start spatial data analysis and processing with self-developed processing software and high processing accuracy.
