摘　　要：本文介绍了重庆城市空间数据生产管理现状、数据更新保障机制,着重介绍了综合运用全野外数据采集、规划管理成果、航空摄影测量、卫星遥感影像、缩编等手段更新系列比例尺空间数据的技术方法;针对院空间数据生产库(制图库)与应用库(GIS库)衔接不紧密的现状,提出了生产库与应用库双库存储模式解决方案,既解决了复杂生产数据的数据库管理问题,又满足即时向政府部门及社会提供地理信息服务。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.
