A Framework For Ubiquitous Geospatial Information Integration On Mobile Device Using Orchestration of Geoservices

Geospatial information is one of the essential information in our daily life for any type of decision makingespecially in emergency situation. But most of the organizations collect geospatial data for their ownpurpose in a proprietary way. The current development of geospatial information services emphasis onaccessing and sharing geospatial data from the diverse data repository. Since the amount of geospatialdata is large, distributed, and heterogeneous in nature and needs distributed computation for thegeneration of information, then it is impossible to get the required information in a single click. Theintegration these geospatial data repositories in an interoperable way and processing of thoseinformation will provide the ubiquitous access to geospatial information. The main focus of this paper isto develop a framework which could provide the user specific geospatial information at any location byprocessing of heterogeneous data from the diverse geospatial repositories. The framework utilizesgeospatial web services of open Geospatial Consortium (OGC) standards to integrate the diverse datarepositories in an interoperable manner. An orchestration engine has been adopted to incorporatebusiness logic for chaining of data and processing services to generate user specific geospatialinformation. Two case studies have been presented to realize the orchestration of geospatial webservices.
