Resampling notifications

The purpose of this page is to list at what moments in SNAP a Resampling Issue shall be raised and how SNAP shall proceed. In general, the issue shall always be raised whenever a function is selected that does not work with multisize-products at all or only with restrictions.

Feature	Raise Resampling Issue when a multisize-product is selected and ...	Expected Behaviour on "Yes, resample"	Expected Behaviour on "No, do not resample" / Resampling not possible	Implementation State	Testing State ( does not apply, not correct)	Testing State
