Abstract


This article take source geoscience information browser World Wind as the main object of study, the union present mainstream geoscience information browser、the P2P technology has analyzed the geoscience information browser’s system construction and the key technologies thoroughly, based on this and has conducted the fundamental research and the technical discussion to G/S this new pattern. Through to G/S, the geoscience information browser as well as the P2P these three aspect content’s union, has studied based on the G/S pattern under the P2P technology in the geoscience information browser’s development the applied research.Topic-based group in research“digital China”,“digital city”,“digital traveling”in the foundation, under many project supports, proposed under the network environment the digital globe platform and the G/S pattern new theory. G/S pattern, namely geoscience information browser/spatial information server (Geo-Information Browser/Spatial Information Server) pattern. This pattern is after present network software structure C/S (client side/server) and B/S (browser/server) the third kind of pattern. The geoscience information browser not only supports the present Web browser function, but may also glance over each kind of spatial information, realizes the three-dimensional model to demonstrate that between the browser and the browser data sharing and downloading (reduce spatial information server’s load pressure) and so on functions, will be the next network browser’s important development direction.the this article prime task includes:The first:carried on to the geoscience information browser’s concept and some mainstream’s geoscience information browser introduced that and conducted the research to some key’s technology.The second:introduced the geoscience information browser/spatial information server in detail (G/S) the pattern theory. Has contrasted G/S, C/S and the B/S pattern similarities and differences and the fit and unfit quality. Based on this has drawn out based on the G/S pattern digital globe platform concept. And to has carried on the analysis and the induction based on the G/S pattern’s digital globe platform’s key technologies.The third :introduced that the P2P technology principle as well as the P2P technology and realize the code in the file sharing and the downloading main mentality. The fourth:develops to the topic-based group and unifies the P2P technology based on G/S pattern geoscience information browser application example - - UStar above its foundation, causes between each browser to carry on data sharing. This part introduced in detail the UStar system frame, the feasibility, the technical program, the system function, the system characteristic as well as the system realize and so on.
