LiDAR

LiDAR (Light Detection & Ranging) is a remote sensing technology that uses pulsed laser light to measure distances and create high-resolution 3D models of the Earth's surface and other environments

LiDAR drone mapping is used to create detailed, precise 3D maps and models across diverse fields, lowering mobilization costs and much higher spatial resolution are allowing new LiDAR mapping use cases in several disciplines, such as forestry, bathymetry, archaeology, infrastructure mapping, hazard management

• Forestry: to map terrain under dense canopies.
• Construction: to track progress and calculate volumes.
• Utilities: for inspecting power lines and pipelines. ideal for multiple repeat scans.
• Archaeology: reveals hidden or buried sites or monuments.
• Disaster management: to map flood zones or assess damage, ideal for planning and prevention.
• Mining: captures comprehensive data of hazardous and unforgiving terrain. 

The technology excels at mapping complex terrain, penetrating vegetation, and detecting small objects, making it and efficient and safe tool for inaccessible areas.

Compared to UAV photogrammetry using passive RGB camera sensors, survey-grade UAV-LiDAR features multi-target capability (i.e. multiple echoes per laser shot) resulting in penetration of semi-transparent objects like vegetation. It also delivers precise geometry as well as radiometry (signal strength).
