Vectorized 3D models from UltraCam imagery
Leverage Vexcel‘s state-of-the-art UltraCam large-format aerial camera systems and UltraMap photogrammetric processing software, in conjunction with sophisticated RhinoTerrain and DAT/EM software solutions to create true 3D building models up to level of detail (LOD) 3 for informed decision making. Excellent integrations between interfaces and intuitive data interactions support a smooth end-to-end workflow. The final watertight city models adhere to CityGML standards, ensuring optimal use in subsequent applications such as urban planning and design, Building Information Modeling (BIM), and virtual reality applications.

Correlation between model complexity and production time


The level of detail and complexity of 3D models are primarily determined by their intended application. For instance, certain city models or buildings require a high degree of precision, while simpler representations may suffice for others. As the complexity of the model varies, so does the amount of work involved in creating it. To provide context, we've included examples of 3D building models at varying levels of complexity, along with the average time needed to generate each one.
