7. FUTURE DEVELOPMENTS 
The method described will be developed in an European 
Union 4th Framework project involving University College 
London, The Technical University of Stockholm, University 
of Stuttgart, University of Oporto, Swedish Space 
Corporation and Earth Observation Sciences Ltd. This work 
will concentrate on refining the algorithms already developed, 
automated the areas at present done manually and developing 
new algorithms to handle other types of data such as radar.
