UAV LiDAR for Surveying Hazardous Environments

Considering the health and safety aspects and striving to achieve safer working conditions is of paramount importance regardless of the industry. LiDAR is a remote sensing technology and offers great advantages in hazardous environments where you do not wish to send personnel, particularly when it is used on unmanned aerial vehicles (UAVs) or drones.

ApplicationAdvantages of LiDAR to improve health and safety
MiningMines are inherently hazardous. Trying to reduce the exposure of people within mines is a critical objective for any operator.

Open-pit mines are dangerous places to work because of the many cliffs and steep embankments that may collapse. 3D mapping can be used to understand, and identify both dangerous and safe areas at a mine site.
Geological HazardsLiDAR measures the ground surface with a high level of resolution that enable geological features, such as landslides, fault scarps and earth fissures that are difficult to detect visually because of vegetation, access or other issues, to be clearly visible with LiDAR data.
Landfill sitesAs land-use pressures increase with an expanding population abandoned landfill sites need to be avoided or used in appropriate ways. LiDAR can be used to locate and understand the extent of abandoned or unregulated landfill sites, leading to better monitoring and even remediation in extreme cases.

Use LiDAR to monitor the boundaries of authorized landfill sites to ensure proper management including landfill volume calculations, making facility inventories, detailed information on ground features such as access roads, fence lines, building outlines, and monitoring devices.
MinefieldsA global problem minefields left over from previous conflicts pose a grave threat to humanitarian relief operations, domestic everyday life, limits the land available for agriculture and redevelopment, and future military operations.

Use LiDAR to create Digital Terrain Models to understand the terrain, to plan the demining, and restore the site to its' previous condition. Creating a DTM using UAV LiDAR is an obvious, safe and quick method avoiding any personnel entering the affected area.

In addition UAV LiDAR mapping is:

  • both faster, higher resolution and more accurate than conventional means
  • more cost effective and more versatile than airborne LiDAR on manned aircraft for smaller areas
