Survey by UAV

Brent O’Grady | | Project Management,

UAVs (Unmanned Aerial Vehicles) are small, lightweight planes that are flown by remote control at an altitude of about 100m. The UAV carries a small computer and high resolution camera that takes thousands of overlapping images of the survey area to be mapped.  

TGM now offers aerial survey and mapping by Unmanned Aerial Vehicles (UAVs) with the suite of solutions we provide to our urban development and infrastructure clients.

Data can be collected over large development sites in a matter of hours. The photos are then digitally matched and referenced to coordinated ground marks to create one continuous image and generate contour information for the site. The UAV survey method provides quick and cost effective terrain data for preliminary development assessment and other tasks requiring quality ground data.

A UAV survey provides for the efficient collection of ground data for terrain modelling with the added value of a rectified digital aerial photo to enhance project planning and analysis.

The same technology can be used to compute volumes of stockpiles and determine progress payments for major earthworks projects. UAVs can be used to fly road alignments or borrow pits at regular intervals and document topographical changes.
