Terradata AG creates terrain model with infra3D

Creation of a virtual project space

For the Canton of Zurich, Terradata created a high-resolution terrain model of the 1.3 km long road section of the Dürnten southern bypass. The digital road data from the infra3D platform from iNovitas AG was used for this. infra3D proved to be an efficient alternative to conventional field measurements and provided the basis for project planning.

The challenge

The main challenge was to carry out precise measurements on busy roads while ensuring safety and efficiency. Conventional surveying methods were not suitable due to the volume of traffic and the associated dangers.

The solution

The Canton of Zurich had already digitized the defined terrain in both directions of travel. Thanks to the digitization work on the southern bypass in Dürnten, existing data could be used for the project. The relevant image data was also georeferenced with a high degree of accuracy and integrated into the infra3D platform. This enabled Terradata to create a virtual project space that maps the georeferencing of the image data with an accuracy of 1.5 cm (1σ).

The conclusion

The use of the digital twin in infra3D Edit enabled the project team to access the virtual project space directly from their workstations. The project planning basics could be created easily and intuitively online, eliminating the need for additional field inspections and measurements. With infra3D's cloud-based solution, the Zurich cantonal administration was able to give Terradata access to the digital streets that had already been captured. This avoided the need to capture the data again. Both the project team and the client were able to save time and money while increasing efficiency.
