Generating three-dimensional landscape model is a hot topic in the field of GIS in recent years. It can convert aerial survey data into three-dimensional visual maps, which can show the terrain of the routevividly, and have broad application prospects. In this paper, basic spatial data that three-dimensional landscape modeling needed are obtained by the microstation software and ImageStation SSK based on aerial image, and the data are analysed and processed. The collected data are optimized so that the errors can be found and revised. Existing buildings in the city are modeled by using the IMAGIS 3D geographic information system software, and the application of real photos veneer them made the results closer to the reality. Finally the three-dimensional urban landscape maps are generated, and AVI video is created with 3Dbrows .
