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 organization and the lossless reconstruction algorithm could satisfy customer's demand of quickly access to vector data.
