Geospatial service chaining in decision support systems

Geospatial data has been playing a central role in various decision support systems. Geographic Information system (GIS) captures, stores, manages and analyses and represents those data, there by contributes in extraction of geospatial information from data. Advancements in technology have allowed consuming GIS functionalities as services over the web. Integrating distributed services in terms of service chaining is required for resolving user requirements which needs involvements of more then one services. However, chaining distributed services comes with several heterogeneity issues as syntactic, semantic heterogeneity. Here, in this paper a service chaining approach for decision making systems have been proposed. Semantic heterogeneity among services has been taken care using ontology. A case study has been discussed to show the efficacy of the proposed approach.
