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.

LiDAR Aerial Photography Processing

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.

LiDAR Spatial Data Analysis

LiDAR spatial data analysis involves processing and interpreting the data collected by LiDAR sensors to create highly accurate and detailed 3D models of the Earth's surface. This data can be used to generate topographic maps, detect changes in terrain, measure vegetation, identify and analyze landforms, and more.

Some common applications of LiDAR spatial data analysis include flood mapping, forest inventory, archaeological site detection and mapping, land use planning, and urban infrastructure planning.

The analysis of LiDAR data often involves specialized software tools and techniques, such as point cloud processing, surface modeling, and data visualization. With its high accuracy and precision, LiDAR spatial data analysis is becoming an increasingly important tool for researchers, planners, and decision-makers in a wide range of fields.

Application of LiDAR Spatial Data Analysis

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 etc..
