Overview
Awesome 3D Semantic City Models is a curated, “awesome-style” list of open semantic 3D city and region models, with a strong focus on CityGML and similar formats. It centralizes high-quality, open 3D urban datasets from multiple institutions to make discovery and reuse easier for research, GIS, and 3D city modeling projects.
Features
-
Curated directory of datasets
- Collects open data semantic 3D city and regional models.
- Focus on CityGML and comparable semantic 3D urban data formats.
- Aims to be a more complete list than scattered institutional resources.
-
Semantic 3D focus
- Emphasizes models with semantic information (e.g., buildings with attributes, not just geometry).
- Useful for applications such as urban analysis, 3D reconstruction, GIS workflows, and city digital twins.
-
Aggregation of multiple sources
- Builds upon and complements existing lists and initiatives, including:
- CityGML Wiki “Open Data Initiatives”.
- TU Delft 3D open data / open cities.
- Towards Data Science articles on open-source 3D semantical building models.
- Builds upon and complements existing lists and initiatives, including:
-
Open source repository
- Hosted on GitHub, enabling transparent updates and version control.
- MIT license for open reuse and redistribution of the list itself.
-
Community contribution
- Open to pull requests and contributions of new datasets.
- Provides contact email for maintainers.
-
