Antarctica plays a key role in many scientific questions, of which those related to global climate change are probably the most prominent examples. There are many researches on Antarctic are carried out at present, and some special institutes sponsored by public and private communities are responsible for antarctica data management and maintenance. Antarctic Spatial Data Infrastructure (AntSDI) [1]sponsored by SCAR's Standing Committee on Antarctic Geographic Information (SC-AGI) is the one responsible for Antarctica spatial data maintenance and sharing by means of OGC standard and specification. Antarctica Spatial Data Infrastructure (AntSDI) has already collected huge volumes of geospatial data and offer an opening geospatial information service. In order to management and use Geospatial data efficiently, and enable most of the users can access to Geospatical data and service at will, we firstly must registry data and service into one or more registry center, then we should construct a building system which can supply users a uniform interface to access data and service in registry center and user also can add their own data and service to system and become part of system's capability. in this paper we present GeoAnt, a prototype interoperable AntSDI building system. GeoAnt 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. The paper discusses the system architecture, the individual components of the system and the use of the system in the international project- Grove Mountains GIService Portal (GMGP).
