摘要：Geospatial information is one of the essential information in our daily life for any type of decision making especially in emergency situation. But most of the organizations collect geospatial data for their own purpose in a proprietary way. The current development of geospatial information services emphasis on accessing and sharing geospatial data from the diverse data repository. Since the amount of geospatial data is large, distributed, and heterogeneous in nature and needs distributed computation for the generation of information, then it is impossible to get the required information in a single click. The integration these geospatial data repositories in an interoperable way and processing of those information will provide the ubiquitous access to geospatial information. The main focus of this paper is to develop a framework which could provide the user specific geospatial information at any location by processing of heterogeneous data from the diverse geospatial repositories. The framework utilizes geospatial web services of open Geospatial Consortium (OGC) standards to integrate the diverse data repositories in an interoperable manner. An orchestration engine has been adopted to incorporate business logic for chaining of data and processing services to generate user specific geospatial information. Two case studies have been presented to realize the orchestration of geospatial webservices.
