| Abstract: | Digital city is a synthetic project in which large geographic and trade data are involved in, thus data sharing becomes a key problem. Grid GIS is an outcome of integrating GIS and network techniques, it has a lot of characteristic of network technique such as heterogeneous, extensible, dynamic auto-adaptable, the multistage management, etc. The advantages of parallel processing of grid computing are obvious when it is used in basic data platform construction of digital city. The architecture and core techniques of Grid GIS which suitable for constructing basic data platform of digital city was discussed, it has some guidance effects to the city information building. |
