    About the Canopy Animation         
Measurements of tree cover are made from hemispherical or “fisheye” images of overhead tree canopy. These are compared to measurements made using satellite and PhenoCam images. The following animation was made from fisheye images collected nearly daily during the “start of season” (spring) and “end of season” (fall) at our Reston PhenoCam location during the year 2012.
