Based on the background of developments of surveying, mapping and geoinformation, aimed at the demands of data fusion, real-time sharing, in-depth processing and personalization, this paper analyzes significant features of geo-spatial service in digital city,focuses on theory, method and key techniques of open environment of cloud computing, multi-path data updating, full-scale urban geocoding , multi-source spatial data integration, adaptive geo-processing and adaptive Web mapping. As the basis for it, the OpenGeospatial information platform is developed, and successfully implicated in digital Shenzhen.%基于测绘和地理信息产业发展背景，针对日益增长的数据融合、实时共享、深度处理和个性化的需求，对数字城市中测绘服务特征进行分析，重点介绍符合云计算模型的开放式计算环境、多路径数据更新、多源数据一体化集成、全尺度城市编码、自适应空间数据处理和动态在线制图等理论、方法与关键技术。在此基础上，研制开发了开放式空间基础信息平台，并成功应用于数字深圳的建设中。
