Forest canopy cover is a commonly used ecological indicator variable, but its reliable estimation in the field with, e.g., the line intersect sampling method is laborious. One alternative for obtaining this information quickly is to sample a larger area of canopy from each pre-specified location within a sample plot by using digital cameras and then use image analysis techniques to extract canopy cover from the images. The script presented here is an automated method for the estimation of canopy cover from skyward-looking canopy images obtained with standard digital cameras.
