An active sensing technology with the ability to penetrate vegetation, capture slender objects and work at night or in poorly lit environments—LiDAR is a powerful reality capture tool. Essentially a laser scanner mounted to a drone, LiDAR can effectively deliver accurate point clouds over large and hard to access areas, making it an ideal tool for land survey applications, transport corridors, powerlines and heavily vegetated terrain.
The LiDAR system emits hundreds of thousands of pulses of light per second which reflect off the environment, enabling the technology to capture slender objects and exploit gaps in vegetation cover to capture the underlying terrain surface.
As an active sensing technology, LiDAR is not reliant on ambient lighting conditions or contrasting surfaces, as is the case for Photogrammetry. This allows LiDAR to work at night, in poorly lit environments and capture reflective and non-contrasting surfaces.
A REALITY CAPTURE TECHNOLOGY THAT IS IDEAL FOR VEGETATED TERRAIN, TOPOGRAPHIC SURVEY AND GEOHAZARD MAPPING
APPLICATIONS OF LIDAR
- Vegetation encroachment
- Topographic survey
- Asset survey
- Geohazard identification and mapping
- Low light environments
The resulting data output is a geo-referenced high-density 3D point cloud, which can be further processed to develop outputs including:
- Digital Terrain Model (DTM)
- Triangulated Irregular Network (TIN)
- Digital Surface Model (DSM)
- Elevation Contours
- Watershed analysis
- Feature extraction
- Change detection
LiDAR derived outputs can be easily integrated into your current workflow. We ensure that the data is provided in a suitable format for use in any number of third party applications.
