Light Detection and Ranging (LiDAR)

LiDAR / Mobile LiDAR Services

That We Offers

Light Detection and Ranging (LiDAR) is a proven approach to creating fast and accurate terrain models for applications in many types of industries. The technology is based on a scanning laser combined with both GPS and inertial technology to create a three dimensional set of points (point cloud).
  • Airborne LiDAR services
  • Mobile LiDAR services
  • Terrestrial LiDAR
Airborne LiDAR is the fastest growing area within the geospatial market. Able to cover large areas of land safely and accurately in a matter of minutes, it’s no surprise that LiDAR sensors have been taking to the sky. An Airborne LiDAR System fixed to a helicopter or aircraft is capable of scanning swathes of land covering many miles. Airborne LiDAR sensors are typically housed in a lightweight pod which can accommodate additional equipment, such as an IMU for more accurate data capture and industrial cameras so high definition photos can be overlaid onto pointclouds allowing the user to produce a more detailed 3D picture.
From a robust LiDAR data set, Airborne lasers can create a number of mapping products for its clients:
  • Digital Elevation models (DEM).
  • Digital Terrain models (DTM)
  • Contours of varying intervals.
  • Stope maps.
  • Planimetric mapping.
  • Tree height analysis.
  • Cut and Fill modelling.
  • Ortho-rectification in combination with imagery.
Mobile mapping systems utilize the latest in LiDAR technology, with scanners capable of collecting around 1,000,000 measurements per second. When combined with positional equipment, these georeferenced data points can be used to create accurate, three-dimensional digital elevation models (DEMs) or Digital Terrain Models of almost any environment. Modern mobile laser scanners aren’t just limited to vehicle mounted systems, mobile LiDAR units can now be mounted to backpacks, helicopters and UAVs. Mobile mapping systems also have many uses across a wide range of industries, from surveying applications like city modelling & highway surveys to environmental, transportation and utility mapping. We provide these services for the below industries
  • Agriculture and Precision forestry.
  • Civil Engineering and Surveying
  • Defence and emergeny services.
  • Environmental and Coastal Monitoring.
  • Highways and Road networks.
  • Rail Mapping.
  • Utilties.
Terrestrial applications of lidar (also terrestrial laser scanning) happen on the Earth's surface and can be either stationary or mobile. Stationary terrestrial scanning is most common as a survey method, for example in conventional topography, monitoring, cultural heritage documentation and forensics. 
The 3-D point clouds acquired from these types of scanners can be matched with digital images taken of the scanned area from the scanner's location to create realistic looking 3-D models in a relatively short time when compared to other technologies. Each point in the point cloud is given the colour of the pixel from the image taken located at the same angle as the laser beam that created the point.
