Geospatial data sharing is a concern in geospatial science because
of the heterogeneity of existing geographical information systems.
This study aims to examine the use of Geospatial Semantic Web technologies
such as ontology, web services and the service-oriented architecture
for enabling disparate heterogeneous legacy GIS to share and integrate
information in a cost effective way to reduce spatial data duplication.
A framework based on the Geospatial Semantic Web technologies is
proposed in this study Experimental results from an implemented prototype
show that the proposed framework allows searching and accessing geospatial
data and services at the semantic level based on their content instead
of keywords in the metadata.
