Geo-spatial data is increasingly becoming a key element for effective planning and decision-making in a variety of application domains.This has generated the need of sharing the
spatial data repositories,collected/maintained by diverse
organizations mostly for their own application domain.
Enterprise geographic information system (E-GIS) is an
organization-wide approach to GIS implementation,operation
and management of these diverse spatial data repositories.The
main focus of the paper is to propose an architecture for
integrating diverse spatial data repositories for geographic
applications using a service oriented architecture (SOA).The
proposed architecture uses a central ontology of data repositories
for seamless query processing across heterogeneous data sources.
The ontology can be viewed as defining a database of objects,
connected by roles,which will help in interpreting the semantics
of users’ request.Two level ontology namely,domain and
application ontology is used for understanding and matchmaking
the requests with services.The working principle of service-based
discovery and retrieval mechanism has been incorporated in the
integrated system.
