So we have the requirement to use this data for practical solutions. M.O.S.S: developed a platform to generate and manage 3D city models. This platform offers opportunities for practical uses of the data in thematic applications. In cooperation with specialist partners applications are integrated in the platform and the city model is enriched with the results. M.O.S.S: developed a platform to generate and manage 3D city models. This platform offers opportunities for practical uses of the data in thematic applications. In cooperation with specialist partners applications are integrated in the platform and the city model is enriched with the results. It is shown that the usage of 3D building models leads to a new quality in the thematic questions, e.g. the calculation of solar radiation and clouding, simulation of environ-mental phenomenon like noise, air pollutions or flood and the calculation of heat demand in buildings.Text/Conference Paper
