9. 98th ICA WORKSHOP on Generalisation and Multiple Representation, A Coruña, July 7-8th, 2005 Web Services? Web Services allow interoperable machine-to-machine interaction over a network  what HTML-pages for humans are the web services for the machines, therefore they communicate with XML via web protocols and their interfaces are described in a machine processable XML format Characteristics: service oriented architecture (request/response/exception) n-tier distribution (layered architecture) component architecture (generic interfaces) platform independence (web protocols/XML)

10. 108th ICA WORKSHOP on Generalisation and Multiple Representation, A Coruña, July 7-8th, 2005 clustering allows real time typification of symbolized foreground objects (e.g. points of interest) applications- adaptive zooming for web mapping - dynamic mapping for mobile applications limits: only applicable for simple generalisation operations standalone generalisation services interactive solution, generalisation service as toolbox practicable for complex generalisation Application scenarios Web Feature Service Middleware solution Generalisation Service Web Map Service GEO Database http:// GIS Client / Browser Generalisation platform GIS, map production Generalisation Service
