πŸ™οΈ LoD3 Road Space Models

This CityGML dataset contains road space models (over 50 building models) in the area of Ingolstadt. To ensure the highest accuracy geometrically as well as semantically, the dataset was manually modeled based on the mobile laser scannings (MLS) provided by the company 3D Mapping Solutions GmbH (relative accuracy in the range of 1-3cm). Moreover, a complementary OpenDRIVE dataset is available, which includes the road network, traffic lights, fences, vegetation and so on:

  • πŸ“₯ CityGML & SketchUp
    • Download via the releases section
    • Clone the repo: git clone --depth 1 git@github.com:savenow/lod3-road-space-models.git
  • πŸ“₯ OpenDRIVE
    • Download via the website of 3D Mapping Solutions (initial registration required)
    • Relevant OpenDRIVE dataset is named Ingolstadt Innercity Halls and can be found in the demo data area
    • Conversion to CityGML can be carried out using the tool r:trΓ₯n

Further Information

🚩 What is modeled in LoD3?

There are several approaches to model Building in CityGML 2.0 (e.g. see Biljecki et al.). In our case, due to the acquisition geometry of MLS point clouds, the building objects consist of a very detailed representation of facade elements but on the other hand, it might lack roof elements and entities located in the Building's backyard. Thus, we encourage to see the list below for a detailed description of the Building in our Ingolstadt LoD3 dataset:

  • 🏠 Building consists of:

    • Ground Surfaces
    • Roof Surfaces
    • Wall Surfaces
    • Outer Ceiling Surfaces
    • Outer Floor Surfaces
    • Closure Surfaces
    • Windows modeled in detail
    • Doors modeled in detail
    • Building Installations
      • Balconies
      • Passages
      • Arcades
      • Loggias
      • Stairs and Porches
      • (Some) Dormers
    • Textures (approximated based on visual inspection)
  • 🏠 Building does NOT consist of:

    • Overhanging Building Elements
    • Roof structure details
    • Objects located in the Building's backyard (not facing the street)
    • Building Installations
      • Chimneys
      • Rain Gutters
      • (Some) Dormers
      • Real (e.g. orthophoto) textures

The terminology according to SIG3D.

πŸ“¨ Feedback & Contributions

This dataset is under active development. To expand and improve the dataset, feedback and contributions are always appreciated. Thus, the SketchUp project files are also provided along with creation guidelines. You can also contact me directly via mail benedikt.schwab@tum.de.

🀝 Thanks

Very special acknowledgments are due to Sophie Haas Goschenhofer and Olaf Wysocki, who worked diligently on the development of the methodology and the realization of the modeling.
