City model data
Espoo’s comprehensive 3D city information model adheres to the OGC CityGML 2.0 city model standard.
Espoo’s city information model covers all object types contained and defined in the CityGML standard with the exception of engineering structures (bridges and tunnels).
In addition to the basic objects of the standard (represented in blue), the standard allows Espoo’s city information model to include generic objects. Espoo mainly uses generic objects to visualise underground infrastructure (represented in white, Gen:*).
Levels of detail
The object types of the city information model can be rendered at different levels of detail (LoD) ranging from 0 to 3.
Buildings can be supplemented with wall-specific textures (Appearance) as https links.
The city model also includes roof textures but the data transfer formats WFS, CityGML and SKP do not currently support roof textures.
