Abstract

In tackling the Semantic Web, a rich domain that requires special attention is the Semantic Geospatial Web. In this paper we make a contribution to the Semantic Geospatial Web by defining an approach based on an ontology for integrating non-spatial resources such as html, pdf, pictures (gif, jpg), etc., with GML documents. It is based on a Catalog which stores descriptions about both non-spatial resources and GML documents. These descriptions have to satisfy, fully or partially, an ontology to be stored in the Catalog. Thus, this approach allows the execution of queries that include spatial and non-spatial operators over both kinds of resources.
