Development of an ontology-based service oriented architecture framework for national geographic information system in Taiwan
Sun, Chih-Hong et al.
Spatial data infrastructure (SDI) is currently being set up with regions, countries, and across national borders to facilitate management and access to geospatial information. GIS services include GIS data services and geoprocessing services which are the main components of SDI to provide remote, standard, and reusable geospatial data and function services. The information, metadata or input/output data description, would all be recorded in catalogue services for users to discover suitable GIS services. This paper introduces the current effort in Taiwan government to develop an ontology-based service oriented architecture framework for National Geographic Information System (NGIS). The NGIS is the system of geographic information systems for the whole nation that serves as a comprehensive repository of the geospatial data pertaining to all the government agencies of the nation. It integrates different types of digital geographic information to establish the spatial data infrastructure for information sharing. From the information technology perspective, NGIS serves as a multipurpose geographic information system, whose scope includes the entire nation. The nationns government agencies, professionals and researchers involved in spatial analysis can retrieve, store, analyze, and perform multifarious tasks using the digital spatial data available over the network. Therefore, the establishment of the NGIS is an indispensable infrastructure establishment for a country like Taiwan, which is moving towards the objective of Digital Taiwann.
