For many technical applications, such as visibility analysis, it is sufficient to consider only the shape of the buildings in the 3D city model. For public presentations, however, the photorealistic texturing of the city model is recommended because it makes it much easier to orient in the model and the acceptance is increased. Thanks to texturing, the city model appears much more detailed as it might even be. Windows, doors or roof structures can be seen, although they are not modelled in the geometry of building models.

Our cost-effective process for the complete texturing of the roofs and facades of the entire city model is based on georeferenced aerial images as they are typically available for all major cities. Even for capital cities with several 100,000 buildings, we are able to perform an automatic texturing of aerial images within a couple of days. The resolution of the texturized model is suitable for visualization in overflights.

If you also want to offer a visualization from the pedestrian perspective, the typical resolution of aerial images is no longer enough. We can, however, offer high-resolution texturing from georeferenced panoramic images of mobile mapping systems in advance. This method also works automatically and provides detailed textures on the street-side facades of the building models, which also look appealing when viewed from the pedestrian perspective.
