Abstract：The paper establishes the real scene 3D model and monolithic 3D model based on the oblique photogrammetry technology,and combines the monomeric model with the hierarchical household processing to realize the monolithic expression of the oblique photographic modeling data.The point cloud data obtained by laser scanning technology is used to build a realistic indoor 3D model based on the real spatial location and spatial relationship within the building.Combined with the deployment and use of geographic information system(GIS)basic support software,an accurate,efficient,visual and all-round urban GIS service platform is established.To realize the construction of 3D geographic information data for urban planning and land resources management.The research shows that a real-scene three-dimensional model can be established by using aerial oblique photography technology and combined with urban GIS service platform,the construction and application of three-dimensional geographic information data can be realized.
