摘　　要：全面推进城市数字化转型是上海推进高质量发展的重要战略。超大城市的科学化、精细化、智能化治理迫切需要构建基于地理实体的、既能精准映射物理世界又能融合城市实时运行信息的三维空间地理数字底座。本文结合超大城市精细化治理与城市数字化转型的需求,分析了传统测绘技术在空间地理信息采集、信息融合和应用的技术瓶颈与难点,并从全空间地理信息快速获取、多源信息精准融合和多场景智能应用3个方面提出了上海三维空间地理数字底座构建的途径,形成了超大城市数字化转型地理信息数据成果与服务新模式。Comprehensively promoting urban digital transformation is an important strategy for Shanghai to promote high-quality development.The scientific,refined,and intelligent governance of mega cities urgently requires the construction of a three-dimensional spatial geographic digital base based on geographical entities that can accurately map the physical world and integrate real-time urban operation information.This article analyzes the technical bottlenecks and difficulties of traditional surveying and mapping technologies in spatial geographic information collection,information fusion,and application.It also proposes ways to build a three-dimensional spatial geographic digital base in Shanghai from three aspects:rapid acquisition of spatial geographic information,precise fusion of multi-source information,and intelligent application of multiple scenes.A new model of geographic information data achievements and services for mega cities has been formed under the background of urban digital transformation.
