LRI provides airborne LiDAR surveys through the use of calibrated laser technology coupled with high-end GPS and IMU systems. This form of remote sensing provides precision remote sensing data, and coupled together with our value added business advice, will suit to your land management needs.

This highly accurate application makes LiDAR suitable for a wide variety of sectors, namely:

  • Forestry
  • Urban areas
  • Agricultural
  • Environmental
  • Mining
  • Engineering



LiDAR (light detection and ranging) is the most accurate and efficient way of determining the precise elevation and geographical location of the earth's surface and features on it.

LiDAR data is produced from a laser devise that generates an intense beam of light of a fixed wavelength. LiDAR can be used in various ways, one of which is via airborne survey, where the beam of light/ pulse is projected from an aircraft towards the earth surface.

The receiver on board the aircraft is able to accurately measure the time of travel of the reflected pulses and well as the intensity of light that returns.

Together with the use of the GPS and the IMU system, coordinates are calculated for each pulse fired.

 LiDAR Aircraft

Utilization of an aircraft is the most advantageous way of capturing large areas of land timeously.

Together, the collection of pulses acquired builds up an accurate 3D map or 3D point cloud model of the earth’s surface, depicting surface elevation together with vegetation and manmade features.



LiDAR very accurately determines the precise elevation and geospatial location of features on the earth’s surface.

One of the most beneficial uses of LIDAR is the ability of the laser pulses to penetrate through objects such as vegetation and detect the surface value below, which was not always possible with photogrammetry.

One set of data can provide multiple uses to clients in various industries:

Forestry Management and Planning:
  • Accurate mapping the ground beneath the forest canopy & establishing accurate contour data
  • Accurately predict canopy bulk density and canopy base height.
  • Measurement of peak height to estimate the root expanse of the trees.
  • Digital Surface Models (DSMs) of town and city spaces
  • Calculate Cut & fill, culvert sizing, vegetation removal, grade calculations and more.
  • Height clearances
  • Elevation map of the farmland
  • Slope and sunlight exposure analysis
  • Irrigation runoff analysis
  • Accurate flood prediction models
  • Calculating stockpile & pit volumes
  • Elevation models for environmental engineering, hydrological and drainage planning
A beneficial to consulting engineers, who require accurate datasets before planning out constructions of roads, bridges, pipeline, etc.
This is an invaluable tool for technical requirements for future development.
