In the last years, 3D city models have become an important topic in the Geoinformation Departments of many German cities. The city of Kassel began building such a database more than 10 years ago. The most important application area of the now quite extensive database is the support of urban development processes as well as a visually sustainable improvement in the preparation and integration of construction projects. Kassel relies on the three platforms “Desktop Scene” (exe-files), Online-Viewer and the output of analogue Haptic Models.

建筑师，城市规划师和3D城市模型卡塞尔的进一步发展

近年来，3D城市模型已成为许多德国城市的地理信息部门的重要话题。卡塞尔市十几年前就开始建立这样的数据库。现在非常庞大的数据库中，最重要的应用领域是对城市发展过程的支持以及对建设项目的准备和整合的视觉上可持续的改进。Kassel依赖于三个平台“ Desktop Scene”（exe文件），Online-Viewer和模拟触觉模型的输出。
