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) 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).
Spatial information dissemination is a necessary step to make use of spatial information for which is a bridge between
the acquirement and the application of spatial information. However, conventional methods of spatial information
dissemination cannot cater to users in that not only users' personalized requirements cannot be satisfied, but initiative
dissemination service cannot be provided. In this paper, the idea of intelligent spatial information dissemination (ISD) is
proposed. Combining the ideas of personalized information retrieval, information filtering and recommender systems,
the ISD system employs user profiles and query conditions to provide two implement ways of spatial information
disseminations, namely "pull" and "push". Then, the three layers architecture of intelligent spatial information
dissemination system based on user profile model is given, and the procedure of data in the ISD system is introduced.
Also, the user profile is presented including user profile model and user profile management. Finally, the prototype
system of intelligent spatial information dissemination is presented.
