Facts:
Images from all cameras are uploaded to a central server every hour between 6 AM and 6 PM (13 images/day). The images are analyzed automatically concerning green-ness in defined region of interests (ROI's).
ROI's are selected where homogenous part of the vegetation can be distinguished, either in the canopy or on the ground vegetation.
Seasonal variation of green-ness indicate when leafing and senescence occurs in the local environment of the camera.
