Minimize Resolution and Swath

Spatial resolutions depend on the acquisition mode and the level of processing.

The SENTINEL-1 constellation offers an improvement in revisit time over ERS-1/2 and ENVISAT ASAR and a continuity of wide area coverage as with ENVISAT ASAR, but achieving higher resolution and potentially global dual polarisation coverage over landmasses.
