Modeling an interoperable multimodal travel guide system using the ISO 19100 series of international standards

ABSTRACT

The ISO 19100 series of international standards are not just standards for data exchange format (e.g. spatial data transfer standard) or a metadata; rather, they provide a pool of standardized methodologies and standardized conceptual schemas to specify geographic information in a uniform way in order to achieve the full spectrum of interoperability during geospatial processing. We propose a canonical model approach based upon the ISO 19100 series of international standards as a feasible and effective conceptual framework for the development of an interoperable GIS or its application. This paper applies the proposed approach to modeling a specific GIS application, multimodal travel guide system (MTGS) to demonstrate the feasibility and effectiveness of the proposed approach. Based upon functional requirements of the MTGS, we show how application schemas for the MTGS in Unified Modeling Language (UML) can be efficiently and effectively developed both by the reuse of the standardized schemas of the ISO 19100 series and by the extension of the standardized schemas in accordance with the rules of application schemas in ISO 19109. We lastly demonstrate how the MTGS UML application schemas can be successfully implemented as platform neutral encodings, i.e., ISO 19136 -- Geography Markup Language (GML), for interoperable information exchanges.
