Canopeo Drag&Drop is a browser-based tool for measuring fractional green canopy cover from images. No account, no server — everything runs locally on your device.
Algorithm
Pixels are classified as green vegetation when R/G < threshold, B/G < threshold, and 2G − R − B > ExG
Privacy
Images never leave your device. EXIF metadata (GPS, timestamps) is read locally from the uploaded files.
