3D BGT visualization of Oudegracht, Utrecht. The 3D BGT was generated using [3dfier](https://github.com/tudelft3d/3dfier) tool. AHN 3 and BGT data were used as input for this tool. The output is a 3D BGT (LOD1) of the city. The building objects (red) were replaced with the [3D BAG](https://3dbag.nl/en/download) (LOD2.2).
Furthermore, the scan (white) and voltage cable networks (blue and black) ([Stedin](https://www.stedin.net/zakelijk/open-data/liggingsdata-kabels-en-leidingen)) data were added. The visualization serves as a proof-of-concept towards the application of GIS and scan data for building a Digital Twin City.
