The mail questions of this study are how to reuse GIS applications and what to do for interoperability of the applications in local governments. To answer the questions, related technologies and standards of GIS are investigated. International standard organizations, such as ISO/TC211 and OGC(OpenGIS Consortium), are working on GIS interoperability standards based on component technology and distributed computing environments.
In this study, a standard mode for interoperability of GIS applications in local governments is proposed nased on the international standards. Standardization process of GIS interfaces in local governments is as followed: 1) modeling of GIS business and 2) establishment of GOS service architectures 3) defining GIS standard interfaces 4) GIS component.
In conclusion, by developing interoperable GIS applications based on component technology, the reusability in local governments can be realized.
