Semantic Interoperability of Field-based Thematic Geographic Information

A model for semantic interoperability among a repository of geographic datasets from different providers is proposed in this article. Specifically, this approach focuses on qualified field-based geographic information. Our solution is based on an ontology describing geographic themes. We present a method to build up this ontology from the data schemas of each dataset in the repository. We have developed a tool, which is currently being evaluated by users, to support this process.
