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.
