"WebFor a conical scanner, the major and minor axis of the elliptical footprint stays consistent across the scan, but the cross-track scanner will have the cross-track axis (vs. the along or down track axis) increase as the scan angle increases. Therefore, the cross track has very unequal spatial resolution across the scan. " - Cross track vs along track
