LiDAR


Many still view airborne lidar applications through the use of fixed wing pilot aircraft. While manned aircraft can cover larger distances in one flight, the high cost of renting LiDAR equipped aircraft, pilots, lidar trained engineers has kept the use of this extremely useful technology pretty much to the minimum.  Only big money and big budgets could afford to use airborne LiDAR systems regularly. With the tremendous improvements in drone technology, drones are enabling aerial surveying where it was either not possible due to the site location, or simply was not economically feasible.

Lidar, (Light Detection and Ranging) by definition is a remote sensing method which uses pulsed laser light to measure ranges (variable or changing distances) to the Earth.  The lidar instrument fires rapid pulses of laser light at a surface, some at up to 150,000 pulses per second. SkyGen’s 32 laser LiDAR system offers unparalleled resolution and accuracy of up to 110 data points per square meter at a resolution of +/- 1cm providing cost effective means to acquire surveys with accuracies of 1-2cm, and even sub-centimeter.

Application of LiDAR, with it’s additional ability of penetrating dense canopy and vegetation, allows the capture of square kilometers in a single day with 80-110+ data per square meter as opposed to manned aerial LiDAR of 4 point per square meter. The end products offer unparalleled precision allowing 3D models to be used in any planning, design and decision making processes across multiple business sectors.
