This is a yolov8 based object detection model for beaver dams and lodges from aerial imagery

This is a semi-serious side-project to detect beaver dams and lodges from aerial imagery. Beavers are expanding into Arctic regions, which can be even observed indirectly from space. With very-high resolution data from UAV or airborne missions, we can try to map dams and lodges directly.

• This model takes RGB aerial images in high spatial resolution, suhc as UAV or airborne imagery. It was trained on images from tundra regions in NW Alaska.

• Target objects were hand labelled with roboflow --> https://app.roboflow.com/awi-response/beaver-finder-vhr-imagery-a9hg9/
