摘要：Huge volumes of geospatial data have been collected and open geospatial information service have been set up by both public and private sectors in Antarctica Spatial Data Infrastructure (AntSDI). In order for the geospatial data to be useful, data and service have to be registered into one or more federated registry centre. However, currently it is very difficult for most of users to obtain the geospatial data, the geospatial information service and to turn them into useful information. In order for geospatial information to become the mainstream ones so that everyone can obtain and use them at will, interoperable AntSDI are needed urgently to find the geospatial data and service related to Antarctica intelligently, classify and register the data and service into global polar registry centre automatically, integrate and extract the data and service into knowledge flexibly. This paper presents GeoAntarctica, a prototype interoperable AntSDI building system. GeoAntarctica is a three-tier standard-based open geospatial web service system which fully automates data discovery, access, and integration steps of the geospatial information discovery process under the interoperable service framework. It also automates a range of geo-computational services at a limited number of geospatial domains and greatly facilitates the construction of complex processing services and modeling. The paper discusses the geo-search concepts that the system is based on, the system architecture, the interoperable geospatial web service framework, and the individual components of the system. The paper also discusses the use of the system in the international project- Grove Mountains GIService Portal (GMGP)
