The urban three-dimensional geographic information system is an important part of the smart city, and it has become a research hotspot in the field of surveying and mapping geographic information. From the perspective of constructing a three-dimensional urban geographic information system, this paper determines the technology and method for establishing a three-dimensional urban geographic information system. Based on aerial photographs, oblique photographic models and vector data, a three-dimensional urban scene model is established, which combines the traditional land. The spatial planning model is transformed into a modern planning model that takes into account the overall situation and provides reliable three-dimensional geographic data support for territorial and spatial planning and management.
