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 grid pattern, taking pictures with the downward facing camera. Each photo is georeferenced, enabling the computer software to stitch the overlapping photos into a 2D map and 3D model. Resolution can vary between 2-4cm per pixel depending on a few factors such as height, camera resolution and the percentage of overlap.
Large areas can be captured quickly giving you an aerial perspective of your site.
