Aerial survey is also commonly referred to as aero photogrammetry. This is a process used by surveyors to capture imagery or geometrics that wouldn’t be possible to examine on the ground. For this process to be successful, the camera is in an elevated position.
Experts should be well versed in the process and have the necessary equipment for successful completion. High-quality equipment is needed both in the air and on the ground. The equipment used includes hot-air balloons, helicopters, airplanes, drones. Also, having portable bags and necessary cases goes a long way in shielding the equipment from harm.
Surveying areas with high automobile and foot traffic is difficult. The same goes for vast land with dense vegetation. This makes such environments perfect for aerial surveying. As mentioned in the equipment examples above, both manned and unmanned aerial crafts are used in taking photos of the designated surface.
The usefulness of this process has resulted in its use in various fields. These include; land surveys, monitoring vegetation and ground cover, wildlife and insect population monitoring, fishery surveys, and archaeology.
Also, there are three different kinds of aerial surveys. Therefore, clients should know beforehand which one they require. These are:
Thermal aerial survey
Color aerial survey
Digital infrared surveys
NOTE: With increased technology over the years, companies are relying more on unmanned aerial vehicles (drones) compared to traditional crafts.
