knowledge tailored their individual needs, rather than only raw | 
data that needs further processing. The system demonstrates | 
the basic functionalities of catalogue search, service chain | 
construction and registration, and chain execution. In the future, | 
more functionalities will be added to the system, such as an | 
ontology service, automatic service chaining based on user | 
request and service type and data type matching. The 
development of this prototype system will provide us valuable 
experience for developing operational, interoperable, 
distributed, standards-compliant and intelligent: Web-based 
geospatial information systems.
