While many organisations and companies are still con- 
centrating on spatial database development and hard- 
copy maps, more and more attention is now paid to 
value-added products. The Amsterdam Congress 
recognised 'the need for efficient processing and pres- 
entation of such data in a value added form', and rec- 
ommended 'the development and validation of end-to- 
end processing systems for specific applications, 
making use of a range of imaging systems, a range of 
components from the spatial information sciences and 
paying particular attention to techniques for the delivery 
and presentation of information'. Designing a spatial 
image-based decision support system for solving user's 
specific problems is one of tendencies now. The other 
direction is to develop spatial analysis systems for inter- 
preting and mining the raw and historical data. More- 
over, new visualisation platforms, interface devices and 
metaphors present more opportunities for scientists to 
explore and share complex remotely sensed datasets. 
Three working groups are proposed for enhancing the 
academic exchange and promoting the development in 
the field of value-added spatial data application, three 
working groups are proposed, one is the WG on the 
design and operation of spatial decision support sys- 
tems, the second is on spatial analysis and visualisation 
systems.
