ImageAir uses LIDAR (LIght Detecting And Ranging) and Stereo systems to produce high quality and detailed images of a terrain that is used to define the ground and features on the ground. The benefit of LIDAR is that it can be used to map buildings or vegetation with absolute accuracy so that all features above ground can be captured in a 3 dimensional detailed image design.

Such modelling provides clear picture of a terrain’s landscape in a short timeframe. Only one flight is needed to capture all the necessary data as it is gathered at the same time as any aerial photography. It is ideal if you’re looking for a model to help with the research phase of any developmental work planned on a terrain, with infrastructure or vegetation. Terrain Modelling also penetrates thick vegetation so can ideally be used to model height or elevation, shape and density. It can map small specific areas, or large areas and still have accurate data on both.

These images are captured by ImageAir and modelled using RIEGL LMS-Q560 Full Waveform, a revolutionary 2D laser scanner. Accuracy of the terrain’s height and ground level are captured by obtaining the precise position of unknown points with a Differential GPS system (John Deere, Starfire and Trimble). Once created into a 3D image it can be used to profile contours; surface displays, volumes, surface area, intersections, points and breaklines.

General Terrain Modelling and mapping is ideal for:

  • open cut mine mapping
  • preliminary design work for farm design, powerline construction, roadways, train lines or pipeline work
  • any land development projects
  • environmental impact measurement projects
  • flood and sea rise modelling
  • vegetation mapping and detailed profiling
  • carbon accounting measurement
