Images taken with aerial photography or optical satellites are not feasible because of both the cost and cloud cover associated with such methods.

But radar can penetrate cloud cover to give satellite maps of areas - once the data has been treated.

Pictured are the mudflats of Solway in Scotland, with the light blue areas depicting flatter areas and darker areas representing the hilly regions of the mudflats.
