| Abstract: | P2PGIS is the combination of P2P and modern Geographical Information System(GIS).P2P oriented raster geo-data sharing has been widely applied;whereas the combination of vector geo-data and P2P still has many issues that can't be handled.Index mechanism of P2P-oriented distributed vector data was researched deeply in this paper,and the pattern of vector geo-data organization based on Linking Mechanism,segmentation and lossless reconstruction were proposed in this research.Experiments showed that the organiza... |
