Hi,
I am actually seeing this error (5000.00 meters per pixel…) quite often and it appears to be semi-random and not necessarily related to the spatial resolution (I don’t specify any).
@jeroen.dries the idea is to combine the two illumination angle bands with a DEM into a single datacube (see the question on data types) and use them as input into the shadow detection UDF. In the final implementation this datacube might also have reflectance bands but for now during the UDF development I just use those three bands.
