Elements Of Remote Sensing
Due to scan geometry of a satellite sensor:

The off-nadir resolution is degraded

The ground distance swept by the senor, IFOV is proportional to sec2θ, where θ is the angle of scan measured from the nadir

All of these

The details towards the edge of the scan get compressed
