View district buildings and model terrain on a map, then turn on map terrain to compare the wider landscape.
Import the geographic IFC with viewer.add() and show its map with viewer.toggleMap(true). The model includes terrain; optional map terrain is a 30 m surface. Use this example for urban context, not detailed construction levels.
Copy this folder and serve it over HTTP, for example python -m http.server 8080. Open http://localhost:8080/; the SDK and sample downloads require internet access.

Complete original published IFC4 urban geodata export; contents unchanged. Buildings, terrain and mapped infrastructure use Swiss LV95 (EPSG:2056), metre units and the declared LN02 height datum. The model includes its own IFC terrain; the optional 30 m Copernicus surface includes roofs and vegetation. This is geographic context data, not a detailed construction-design model.
