By building a unified three-dimensional urban spatial governance platform based on real life,this paper adopts the dual-engine architecture of"GIS engine + illusion engine"to solve the problem of insufficient GIS data management and analysis ability,and at the same time,enhances the expressive force of fine scenes.LOD multi-level 3D model loading method is adopted to reduce the amount of entity data to be processed in rendering cycle and improve the loading efficiency of 3D model.The skew model is loaded by dynamic video stream technology to fully ensure the security of geographic information data.Taking Panyu District construction project,as an example,it has been effectively applied in urban comprehensive improvement,three-dimensional auxiliary examination and approval and urban quality improvement,which provides reference for urban space comprehensive management construction.
