Can Lidar See Through Forests to Aid Geological Surveys?

May 16, 2023

LiDAR is the product of the combination of laser technology and radar technology, a new ultra-high performance, highly integrated and calibrated dual-channel airborne laser scanner system. The laser radar of Feiyan Aviation Remote Sensing has a maximum laser emission frequency of up to 2 million Hz, an effective ground measurement speed of 1,330,000 points/second, and can operate at an altitude of up to 4,700 meters. The system is capable of flying operations at different altitudes to obtain large-scale, high-density point clouds. Therefore, it is especially suitable for aerial surveying and mapping of very large areas and complex urban environments. In addition, users can make effective flight plans in complex terrain, improve flight efficiency, and ensure flight safety.

LiDAR forest survey can automatically generate chart products such as forest area, ground conditions of patrol and scientific research surveys, forest appearance, growth, road network, residential distribution, water network, vegetation height, average diameter at breast height, tree height, and harvesting planning through software . This technology can conveniently monitor the stock, status and changes of forest resources, and it is suitable for successive years, and the comparison data is more convincing. Therefore, it is very suitable for today's natural resource management system that needs to be reported on an annual basis.

Self-owned LiDAR Aerial Camera

Most of the laser scanners that can be carried by drones in China are as big as cans, and most of the lasers emitted by them can penetrate the forest canopy. However, due to battery reasons, drones generally stay in the air for a relatively short time, and the forest area that can be covered is not large enough.

Our company supports both manned and unmanned aircraft airborne LiDAR aerial photography. Feiyan Aviation Remote Sensing Technology Co., Ltd. is equipped with two of the most advanced RIEGL VQ-1560i airborne LiDAR measurement systems in the world, which are applied to high-density point clouds A full-waveform digital dual-laser transmitter airborne LiDAR system for mapping and super-large-area surveying and mapping.

The RIEGL VQ-780 II waveform processing airborne laser scanner, with a pulse repetition rate of 2 MHz and more than 1.33 million measurements per second, provides mission results for higher density and ultra-wide-area mapping, and further increase productivity.
