Spectral Checkerboard
When overlapping separate high resolution images of the woodland, there are likely
to be areas where the overlapping pictures do not exactly align for all pixels, particularly around object edges. Edge effects are imperfect overlaps of the layers that
cause the spectral signature of a pixel found at the edge to show incorrect reflectance spectra. For example, a signature at the edge may have 4 bands showing a leaf
