infra3D for the city of Bremen
The digital road broadens the perspective in the digital twin of the city of Bremen
With the integration of iNovitas' infra3D View into the 3D city model solution from Virtual City Systems, the city of Bremen can use its existing mobile mapping data intuitively and sustainably. The employees of the Bremen city administration benefit from a broader perspective and a valuable source of information for their work.
The challenge
The State Office for GeoInformation Bremen aims to ensure that existing geodata and street images are used in a variety of valuable ways throughout the city administration. In 2019, the city of Bremen launched its digital twin and has been continuously developing it ever since. As part of this digital twin, various existing data are to be flexibly integrated and made accessible for broad use in the administration.
The solution
At the beginning of 2023, the digital street was added to the infra3D View. In infra3D View, the city administration can now use its existing street scene data easily accessible, sustainable and integrated. The street scene data (mobile mapping data) was originally collected for a road condition assessment and offers a 360° panoramic view of the street comparable to a pedestrian's perspective. The high-resolution images are an ideal addition to the 3D city model made from orthophotos and a valuable source of information – provided they are accessible and easy to use.
This has been made possible by the teams from iNovitas and Virtual City Systems. Together they realized the elegant combined solution of the infra3D view in the 3D city model solution VCmap. The 3D city model from Virtual City Systems GmbH supports the optimization of internal work processes and has already established itself as a valuable tool for the entire urban community of Bremen.
iNovitas integrated the city of Bremen's existing mobile mapping data into the cloud-based software solution infra3D View. The provision of anonymized mobile mapping data as a digital street, independent of the data collection service provider, is an often-appreciated advantage of infra3D. In infra3D, rarely used street image data develops great added value and can be used for a wide range of activities throughout the city administration. Investments made retain or even increase their value and enable long-term cost savings.
The solution is also flexible when it comes to user rights: while the 3D city model is publicly accessible, the digital street in infra3D is reserved for city council employees. Users can access the digital street in infra3D View directly in the 3D city model and look around the 360° images of the street space. Facades, objects and other details in the street space are clearly visible. Furthermore, the lines could be integrated as a geodata layer and faded in. The digital street can thus be used for visualization, inspection and inventory in the street space.
infra3D View is being used more and more by employees of the Bremen city council to obtain valuable information from the street space without having to go on site. For example, an inventory of parking ticket machines with their location addresses could be created from the digital street to 90%, so that only a few machines had to be specifically checked outside. Bicycle racks, benches and billboards can be inventoried. Requests for e-charging stations can be estimated on screen. The city administration of Bremen is using more and more possible applications, thereby increasing the added value of the digital street, the infra3D View and the digital twin as a whole.
