# 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.

## Info
- Model file in pytorch format for ultralytics yolov8
- bounding boxes of beaver dams and lodges
- trained on aerial imagery from West and Northwest Alaska
- More info: https://essd.copernicus.org/preprints/essd-2023-193/
- 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/
