The Development of Urban Landscape Three-Dimensional Visualization System

Combined with integrated management function of three data libraries (DEM, DOM and DLG) and based on the digital photogrammetry workstation (DPW) such as the JX-4A three-dimensional code data collection, GIS data, AutoCAD data, the three-dimensional model of the city was built. The urban landscape three-dimensional system was developed using VC++ and OpenGL, which was used in data collection and digital modeling of urban landscape, and was applied to many fields such as urban landscape design, landscape planning, landscape evaluation and urban landscape facility enquiry etc. The three-dimensional visualization application system was set up realizing the three-dimensional visualization operation and analysis to the application system.
