uh...
speaking about resolution is very hard, because this term is related to both cartographic and imagery resolution. More over you can speak about spectral and spatial resolution.
In most cases psectral resolution refers to number of bands within an imagewhile spatial resolution is related to pixel dimensions of images: that is, the smaller the dimension, the bigger the resolution.
Hope this help...

A simple way to think of remotely sensed image resolution is the size of an individual pixel relative to the ground. Consequently if the resolution of an image is one meter, then each pixel represents a meter on the ground.

Hope this helps,

Greetings:

Also important is to consider the radiometric resolution. That is the "steps" needed to convert the incoming "information" into DNV (Digital number values).... this determines the maximun ranges in values ( e.g. 0 to 255)

And what about the temporal resolution???

there are
Spatial resolution: the spatial extent covered in a single pixel (irs p6 liss 3 ::: 23.5m)
Radiometric resolution: the number of colours (8 byte w.r.t irs p6 liss 3 multi spectral data )
temporal resolution: how many days once the satellite completes one cycle (24 days)
