Abstract: Urban digital transformation, "scientific, refined, and intelligent" urban governance, the implementation of "new infrastructure" and the development of digital economy all urgently need spatial geographic data to advance to "full domain, holographic, full space, multidimensional, and high-frequency" and realize the digital twin of physical space. This article combines the new needs of geographic information in the urban digital transformation of Shanghai, proposes a new surveying and mapping system with intelligent pan-info surveying and mapping which based on geographical entities as the core from the aspects of multiplatform collection technology, holographic data content, 2D and 3D integrated form of results, update method and on-demand assembly of services, and forms a solution to new geographic information services for urban digital transformation.

Key words: digital transformation, intelligent pan-info surveying and mapping, digital twin, geospatial digital base, geo-entity
