| Abstract: | While the surveying and mapping of the urban basic scale topographic map is gradually completing,surveying and mapping achievements become richer and richer.Urban survey units face an important topic of updating data,managing data and providing data service.By introducing the production and management of Chongqing urban spatial data,and the assurance mechanism of data updating,this paper focused on the technical methods of updating the series spatial data,which includes the integrated use of all field survey,urban planning and administration achievement,aerial photogrammetry,satellite remote sensing image,and ma Pgeneration and compilation.To address the incompact linkage of spatial data production repository(system library) and application repository(GIS database),this paper introduced the dual-mode storage solution to solve the database management problem of complex production data,and meet the needs of providing instant geographic information service for government departments and community. |
