Abstract
The Combination of Geographic Information Services (GIServices) is studied in this paper. First, the way of GIServices combination is analyzed. Based on GIServices combination ways depicted by Service-Oriented Architecture (SOA), OpenGIS (OGC) Web Services Architecture and International Organization for Standardization (ISO) 19119, GIServices combinations are classified into Discrete Service Combination, Chaining Service Combination and Hybrid Service Combination in this paper. Then, the model of GIServices combination is focused. A high-level GIServices combination model based on Petri Net is proposed to improve those proposed by former researchers. The proposed high-level model can represent services combination relationship more clearly and can help to control services combination behavior in an easier way. Since searching GIService that can accomplish certain GIS task is a key step of implementing GIServices combination, GIServices taxonomy is then studied. A multi-level task-oriented GIServices taxonomy is proposed in this paper. Correspondence between GIS tasks and GIServices can be established more easily with the proposed multi-level task-oriented GIServices taxonomy. Finally, a case study is made to support the proposed theories.
