After an aerial survey last year, oblique aerial images, a detailed 3D mesh model and an object-oriented model based on CityGML data have now gone online. Lüdenscheid relies on the VC Planner to digitally plan new construction projects in advance and to analyze their effects on the built environment. It is planned to enrich the digital twin by integrating the urban underground infrastructure. Take a look at the publicly accessible 3D city model of Lüdenscheid. We are excited about the next steps!
