Manager is the administrative basis for merging georeferenced 3D information and managing it in ISO/OGC-compliant database systems. With CityGML, ALKIS3D and SEDRIS-GML the currently most important national and international standards in the modeling of spatial 3D models are supported.

Numerous data interfaces for the import of 3D data are available in the Manager. During import, data is harmonized, checked for completeness and correctness, and subjected to visual inspection.

In this way, the Manager creates the prerequisites for accurate provision of the data in the other 3Gonium tools - but also for loss-free, standard-compliant data delivery to third parties.

Digital Twin

Digital Twin is the tool for building digital twins of a municipality. Various tools support urban design planning, integrate data from LoRaWAN sensors, position wind turbines for citizen participation, simulate the night-time lighting of streets and depict flood scenarios. In conjunction with CPA's mobile GIS, even emergency vehicles can be tracked live.


Texture is the autonomous tool for automatically texturing the building facades of the 3D city model. For this purpose, the most suitable oblique aerial image of a current aerial survey is selected for each building side and individually transformed onto this facade. The sides of the building are then presented in a resolution that can be configured to suit the application. The result can be further improved by localised transformations. Finally, an OGC-compliant CityGML data interface is used to transfer the textured 3D city model to the 3Gonium Manager, which then prepares the presentation for display in the WebViewer.


Construction is the tool for the digitization and editing of 3Gonium's 3D models. Based on architectural plans, floor plans or laser scan point clouds, buildings with any level of detail, facade textures, textured terrain models or in general the 3D elements for the design of urban and rural areas are created. In doing so, Construction follows the underlying data models such as CityGML, ALKIS3D or, in the future, BIM.

For the typical updates to the 3D models, Construction directly accesses the data sets administered in the Manager. The creation of urban design variants is done through a close interaction with the virtual 3D models hosted in the WebViewer.

In any case, standard-compliant datasets are created, that may initially populate or update in-house or external datasets.


WebViewer uses Internet technology for the visualization of 3D city and landscape models. Here, 3D models with very different content are offered via a website personalized for the customer. Virtual cities, regions or entire countries can be displayed.

In addition to visualization, the WebViewer already contains components for analysis and simple planning with 3D models. This includes simple forms of flood simulation, the planning of wind turbines or the positioning and evaluation of lighting facilities.

Integral components of the WebViewer are procedures for user authentication and authorization. These organize the access to individual functions in the WebViewerv and at the same time in comnination with Construction provide a complete administration for the implemented procedures for the creation of urban planning variants. Additionally the WebViewer controls the specific output of the 3D data in the usual formats.


The focus of the Planner is the creation and editing of urban planning variants. For this purpose, the two tools Construction and WebViewer are mutually integrated via efficient procedures of secure data exchange.

While WebViewer provides the data basis for planning and at the same time ensures administration, secure access and visualization of the planning variants, Construction creates the planning variants in any scope and level of detail on the basis of the WebViewer data stock.

In Planner, the user has access to Construction's complete range of services for the digitization of urban planning variants. For example, Construction places the new terrain model exactly in the right place, positions the planned buildings exactly on this new surface and also ensures that facades and other surfaces are displayed in accordance with the plan. The integration of further 3D elements is a matter of course.


Lights is the tool for the evaluation and analysis of urban lighting installations. Street lamps, light columns or spotlights can be geo-referenced and integrated into the virtual 3D city model. With the corresponding parameters such as luminous intensity, light color or light cone, Lights generates an almost realistic representation of the respective lighting situation.

By changing the lighting parameters, different variants can be configured in order to analyze their impact visually and in terms of content. The results can be transferred directly to the WebViewer as a planning variant.

This allows the public to be involved in the planning of energy-related measures in the simplest possible way.


The Dynamics tool is part of the WebViewers. . Its task - to visualize the movement of objects in reality in the virtual 3D world of WebViewer. For this purpose, the geo-positions of vehicles, drones, people, etc. are received by Dynamic in real time, and displayed as a signature or 3D model in the WebViewers. As far as the displayed objects create video recordings in the real world, these appear in the dashboard of the WebViewers.
