ABSTRACT:
Systems, computer-readable media, and systems are provided for determining whether a data point indicates a presence of a shadow-covered ground point. A data point from top of atmosphere data from an imaging study of an area potentially covered by a cloud shadow is selected. At least one spectral data measurement associated with the data point, the spectral data measurement including at least one of visible, near-infrared, and short wavelength infrared data is taken. At least one of the spectral data measurement and derived spectral index is compared with a spectral data threshold, the spectral data threshold delineating between a shadow-covered ground point and a non-shadow-covered ground point. The data point is classified as one of a shadow-covered ground point and a non-shadow covered ground point based on the comparison with the spectral data threshold.
