Canopeo: A Powerful New Tool for Measuring Fractional Green Canopy Cover (2015, methodology): “This software has been used to analyze canopy cover and light interception in soybean (Purcell, 2000), percent turf coverage (Karcher and Richardson, 2005; Richardson et al., 2001), and turf color (Karcher and Richardson, 2003).”
Digital Image Analysis and Spectral Reflectance to Determine Turfgrass Quality (2014, methodology): “Specifi cally, DIA has been successfully used by researchers to assess turfgrass color (expressed as DGCI) and PCov (Karcher and Richardson, 2003; Richardson et al., 2001) since it was documented that such an analysis provides an accurate estimation of both parameters.”
