摘要：This paper presents a study, which aims to generate 3D city models from existing 2,5D maps. A 3D city model is generated via CAD software using the existing photogrammetric 2,5D maps of a chosen pilot area. 3940 buildings, 8000 trees, 810 streetlight lamps are modeled in the scope of the project. Two 1/5000 scaled orthophotos are used for visualization of the surroundings. In order to reach the high vertical accuracy for buildings, extra editing processes are applied to the all buildings in the project area. Therefore, the vertical errors of buildings were corrected on 2.5D photogrammetric maps. Finally a precise and an accurate 3D city model of Be ikta Region is generated and converted into VRML. Using VRML format, it is also possible to visualize and animate the 3D city model on the internet
