Aerial drone survey is a general term often used to describe several different and overlapping techniques:
Structure and Asset Inspection- Employing drones to rapidly conduct inspections at height and places where workers are at risk. See the link for the Drone Inspection webpage.
2D Site Mapping- Using drones to quickly capture geo-tagged aerial imagery of a site then using GIS software to build photomaps and topographical maps, and other drone survey products. See the link for the Site Mapping webpage.
3D Site Mapping (Photogrammetry)- Developing the 2D map into a 3D model to transfer to CAD software for example. Or to take digital measurements including volumes of heaps and piles.
All Services- There are also other use cases that sometimes come under the umbrella term Drone Survey. See our All Services webpage for the list and further info.
