Geographical Information System (GIS) integrates operation and synthesis analysis of multi-factor information, satisfying the demand of high efficiency and visual performance in human computer Interaction, whereas Peer-to-Peer (P2P) technology assigns and utilizes network resources flexibly, making information exchange more dynamic and real-time with participants? autonomy to certain extent. Therefore, by the thought of uniting information processing merits of GIS and P2P, a design method of new information service system - Gippy - is introduced to keep pace with information exchange demands among dispersed governance regions, especially as universities. It is discussed in this paper that Gippy's key achieving technologies including its applications as well as architecture characteristics. We also points out new value-added functions adopted by Gippy, and give a research on feasibility of optimizing and extending.
