Abstract: In the digital age, the refined management of megacity behemoth requires deepening the application of modern information technologies such as the internet, big data, and artificial intelligence. By utilizing precision and intelligence as the driving force, it promotes the integration of urban management resources and processes re-engineering through digital empowerment. In this article, firstly, the concept of urban intelligent pan-info surveying and mapping is proposed in combination with the pilot work of the new basic surveying and mapping in Shanghai. Moreover, its key technologies are introduced in five aspects, including “pan-info data acquisition with multi-sensor fusion, pan-info data fusion and intelligent processing, geographic entity database construction, geographic knowledge service and multi-mechanism triggered data updating”. Finally, the application results are exhibited in various fields of society such as the unified management of urban governance, district-level urban operation platform, and street-level digital twin.
