This detailed map of Bochum has been meticulously crafted from public topographic data available at opengeodata.nrw.de. The horizontal precision is 50 meters, while the vertical accuracy is precisely 2 meters. To highlight the model's intricate structure, the vertical scaling is ten times greater than the horizontal scaling.

I created my model at a scale of 1:200.000, which took approximately 2 hours to complete. Design Process A Python script skillfully converted the elevation data into a sophisticated 3D-CAD-Model composed of thousands of rectangular prisms.
