The Digital Archives Program of Taiwan has accumulated a colossal amount of spatial and temporal GIS data. It becomes critical to set up a GIS environment and a comprehensive platform through which spatial databases created by various participating organizations can be integrated and cross-referenced in a catalog with spatial indexing capability. It is essential for the comprehensive platform to be accessible to all digital archive users and be effective in retrieving data with cross tabulation and indexing. The application of GIS concepts and techniques enables the comprehensive platform to provide powerful spatial querying and referencing functions which are not feasible in traditional cataloging systems. The clearinghouse framework for the catalog of Taiwan Digital Archive Program is developed by using ArcGIS Server, which provides necessary functionality and flexible architecture for future expansion.
