Abstract:
In tackling the Semantic Web, a rich domain that requires special attention is the Semantic Geospatial Web. In order to achieve the Semantic Geospatial Web, an approach to query non-spatial resources using spatial criterions is presented in this paper. The non-spatial resources are well-known web resources represented by HTML, GIF, PDF, etc. However, to use spatial criterions a set of spatial resources with spatial information represented with GML (geographic Markup Language) is necessary. In this way, queries with spatial operators (touch, within, near, etc.) can be carried out over resources. In this approach, the relations between spatial and non-spatial resources are carried out “on the fly” in each query, i.e., they are not manually pre-stored. So, the main aim of this approach is to boost the capacity of Search Engines (such as Google, Yahoo!, etc) in order to include spatial criterions in the queries and not only string matches.
