LIDAR

Laser scanning allows spatial measurements thanks to capturing of a laser beam reflection. This method gives us information on the structure and 3D position of registered objects. The resulting point cloud can have varied density (from several up to several dozens points/m²). Each point is rectified to a system of geodetic coordinates and then classified according to client’s desired schema. The final product may be a point cloud, DTM, DSM, 3D model or visualisation. ALS helps when you need to know the size and shape of an object or to see and model surfaces under tree canopy.

LiDAR Mapping Services


Feiyan Technology focus on offerring high accuracy LiDAR Mapping Services with Lidar aerial photography. 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.

LiDAR Aerial Photography

Using a LiDAR surveying and Lidar mapping service needs to obtain a certain position and coordinate information of the laser, which can be obtained by using GPS technology, and then calculate the geodetic coordinates of each laser point.


The density of laser point cloud data is relatively high and the accuracy is very large. These data can directly examine the three-dimensional coordinate characteristics of laser points and effectively establish a digital elevation model. The laser point cloud data itself is also the most important data product of lidar mapping technology.


For example, the airborne lidar measurement system for forests can simultaneously obtain topographic information and tree height information at the bottom of the tree canopy, analyze and classify vegetation, calculate tree height, tree species and wood volume, and dynamically monitor the growth of plants and extract forests. The real DEM in the area; in the water conservancy department, it is used for flood analysis, ecological assessment, shipping scheduling, water management and other applications.


Application of LiDAR Mapping Services

Aerial LiDAR mapping services can be used not only for traditional photogrammetry purposes, but also for forestry, agriculture, digital water conservancy, urban 3D modeling, electricity, and more.
