Abstract

This paper describes a Web-based query system for semantically heterogeneous geospatial data. Although Web-based information systems are currently being developed by the GIS community to provide data discovery and download capabilities for distributed Web data sets, they do not include the ability to pose DBMS type queries over the data. We developed a system that provides DBMS querying and that also resolves semantic differences that occur in distributed sources. We are working in the context of a proposed statewide land information system.
