If you imagine the pushbroom, you have 9000 cells lined up. Width is 270000 meters.The Eviscerator wrote: If a satellite-based pushbroom sensor has a row of 9,000 CCD cells aligned perpendicular to the satellite's motion, and the swath width is 270 kilometers, what is the ground sampling distance (spatial resolution) in meters?

And I just realized how to do this question *facepalm* so I'll explain it if anyone needs me too.

Each cell encompasses 30 meters.
