Information content of high resolution satellite imagery

A programme of work has been carried out at University College London with support from other mapping organisations in the UK to determine the amount of information which can be extracted from TM and SPOT in comparison with a variety of map scales, and in a variety of different types of area. Detailed plots from multispectral, panchromatic and stereo imagery have been compiled, and compared with available map data. The results from these experiments are presented.
