Terrain Modelling a powerful land management tool for farmers

Airborne Research Australia (ARA) completed a large scale, 20,000 ha, high resolution aerial LiDAR survey over 5 properties in Southern and Central QLD for SkyScan and our industry partner InFarm, based in Goondiwindi. The high-density LiDAR coverage using leading industry sensors provided by ARA allowed us to look through the surface vegetation cover to bare earth giving what is referred to as a Digital Terrain Model (DTM).

With this we can see very fine surface feature that are only centimetres in depth such as old wheel tracks that are just compressions of the soil. Using this data InFarm can provide the farmer with powerful tools to implement detailed land management strategies to maximise water retention, reduce erosion, optimise earthmoving and many other land improvements.
