We are integrating sensors into Unoccupied Aerial Systems (UAS) and using high resolution digital imagery (RGB) in a process called Structure from Motion (SfM) to recreate the three-dimensional surfaces of oyster reefs. This will allow us to relate structural complexity to our other metrics examining oyster reef communities.
UAS, or drones, come in all shapes and sizes, usually grouped into fixed-wing and multirotor aircraft. While both types of aircraft offer their own suite of benefits for research, multirotor platforms provide a stable, low-altitude option for capturing high resolution imagery, which is useful for mapping oyster reefs.
