Earlier this year a property owner in Western NSW engaged Terratest Aero to create a terrain model over their property. Sparse vegetation enabled us to use photogrammetry (a series of images stitched together) instead of LiDAR (a method that uses light in the form of a...

Measuring Erosion and Change Over Time

Drones can be deployed rapidly to assess and monitor areas for erosion. The fast data collection makes them an inexpensive method to cover large areas (around 20ha in 15 minutes) that would take traditional methods much longer to a...

Photogrammetry is the process of stitching multiple photos together to form a 2D map 3D model or structure. Terratest Aero uses UAV’s (drones) to take these images. This process has been proven to be both effective and efficient.

The UAV is programmed to fly a precise g...

LiDAR, or Light Detection and Ranging, is a remote sensing method using lasers to measure distances. These can be combined into a point cloud (millions of points) to produce an accurate model which measurements can be taken.

The advantages of LiDAR is that unlike photog...

Asset Inspections can be costly, time consuming and ultimately results in shutting down the site or production. With the added risk of working at heights its easy to see the advantage of an advanced aerial system.

Our aircraft can inspect difficult to reach industrial a...
