SfM, UAV & Drone Surveys

Unmanned Aerial Vehicles(UAVs) have revolutionised the way we approach surveying and Digital Terrain Models (DTMs). Aerial surveys have now given us the ability to survey areas not previously possible due to hazards or access issues. It is now possible to achieve relatively high levels of accuracy to create large DTM models in a short space time, when compared to traditional methods. 

Greenhatch have utilising the benefits of UAV technology for a number of years and we employ fully trained, in-house CAA approved pilots who utilise our current portfolio of equipment (Mikrokopter Okto XL & DJI Phantom 4 Pro) to provide a multitude of image based services within our group.

Greenhatch have also increasingly been using SfM (Structure from Motion) technology for providing scaled elevation orthoimages for architects and conservation bodies. 

We are also well equipped to provide more traditional rectified photography for suitable subjects including photographic surveys, 360° panoramas and virtual tours.
