Use cases

Administration

The central administration of CityServer3D supports a sustainable development of three-dimensional city models. Data once dearly bought / laboriously acquired can no longer get lost. Due to automated, rule-based methods existing data stocks can be continuously updated, extended, and improved. The development processes can be individually adjusted to the existing system landscape. Hence your city model will always be up to date!

Thanks to the service-oriented architecture of the CityServer3D the data can be made available to different applications and users. Standardised exchange formats (e.g. CityGML) as well as interfaces allow the connection to existing spatial data infrastructures (SDI).

Presentation

Another important application area is the presentation of 3D city models. Especially areas like tourism or regional and city marketing can benefit from well-prepared three-dimensional data. The CityServer3D supports the presentation of the models by an application-based provision and visualisation of spatial information. Furthermore 3D city models can be enriched by multimedia content like text, images, or videos. This enhances the information content thus creating a positive effect of the presentation.

In addition, the CityServer3D supports the connection to mobile end devices. Providing three-dimensional data and integrated multimedia content appealing tourist guides can be created. Using realistic 3D models in navigation devices facilitates the handling of these devices thus increasing their user acceptance.

Planning

If you think of city development the urban land-use planning plays a superior role. The CityServer3D supports this domain by offering the possibility of managing different versions and planning options of a construction project and integrating them into the existing city model. Using analysis and visualisation methods like the shadow effect calculation the impact of a new building on its environment can be estimated.

Standardised exchange formats from the CAD domain are supported which allows the integration of three-dimensional data of a construction project. Digital construction plans can be used for evaluating different planning options. This also allows the participative planning increasing the citizens’ active involvement in the development of the city.

Analysis

The central administration of 3D city models allows quite a number of simulations and analyses. If e.g. you can calculate the sonic wave propagation you can take measures to considerably reduce the noise emission and thus the nuisance. Analysing the radio-wave propagation the coverage of wireless telephone and modern broadband networks can be improved. The simulation of waters that overflow their banks can support the disaster control in preparing reasonable emergency plans.

City models managed in the CityServer3D also include subsoil information which plays an important role in planning the utility supply lines. Furthermore, before acquiring a piece of land or starting a construction project, the analysis of the subsoil is of crucial importance. The connection of other simulation and analysis systems is allowed for by standardised interfaces.
