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
The details towards the edge of the scan get compressed
All of these
