- each product variation has an expected model CRS
- image pixel positions are correctly transformed into model coordinates and vice versa for various bands
- simple raster data ops lead to expected results when applied to product variations: subset (mandatory), reprojection (mandatory), band maths (optional), statistics (optional)
- pixel data extraction as used in spectrum view for various bands in various products
- all bands with same raster size have the same image layout (= same image pyramid models with same tile sizes)
- the valid-masks mask of a band bands (if any) have has the same image layout (= same image pyramid models with same tile sizes) as the band
