| Abstract: | This paper presents a heuristic and practical way of how to use fusion and processing techniques of space information to design an incremental update platform for navigation electric map in broaden depth. Benefited to such platform, ubiquitous spatial services could seamlessly and directly be bridged with it under the help of inconfing techniques： Based on varieties of data fusion and data clean, it is possible to accept muhi-source data in quality way. Based on multi-scale spatial database deployed on different spatial local data grids, it could storage large spatial information as more as possible; Based on service-oriented architecture and leading object-oriented design ideas and idioms, the implementation of product platform is subject to concurrent processing more demands and strongly support data demands of different local business services; Based on the version-enable flow of map product and clear map product definitions, it refreshes navigation map in quarter for full map , in month for important cities, of course, the real data information is released as its intent. As conclusion, the frame- work of incremental navigation map product discussed shares its key techniques in order to set up productive and incremental map product platform to satisfy customers＇ demands as soon as possible and as accurate as possible. |
