Abstract

Aiming at various (near) real-time on-demand services, this paper puts forward the concept of focused geospatial information services with three kinds of service patterns to aggregate and cooperate with all kinds of information services, including the geospatial data services, geospatial processing services, transport network services and sensor services. The challenge of focused geospatial information service is complex in user demand, rich in data dimension, diversified in sensor type, complicated in processing and time-varying in network, which makes intricate in semantics. A hierarchical constraint model is therefore proposed as a uniform semantics description model with four levels including user semantic constraints, data semantic constraints, processing services functional semantic constraint and process service quality semantic constraints. The constraints act role of establishing the connection between user semantics and data services and processing services, and of basic of semantic reasoning in service discovery, selection, and composition.
