3D Tiles

This service provides 3D tiles through a RESTful API, implementing the Cesium 3D Tiles specification.

https://3d.geo.admin.ch/<LayerName>/<Version>/<Time>/<Z>/<X>/<Y>.b3dm

Use the following parameters to define your request:

Parameter	Example	Description
layerName	ch.swisstopo.swissbuildings3d.3d	The technical name of the 3D layer. Possible values are: ch.swisstopo.swissbuildings3d.3d, ch.swisstopo.swisstlm3d.3d, ch.swisstopo.swissnames3d.3d, ch.swisstopo.vegetation.3d
Version	v1	API version. v1 means tiles generated with 3D Tiles
Time	20250501	Date of tileset generation in ISO-8601 (YYYYMMDD)
Z	7	Zoom level
X	54	Tile column index
Y	21	Tile row index

A 3D tile request for swissBUILDINGS3D dataset:

curl -o demo.b3dm https://3d.geo.admin.ch/ch.swisstopo.swissbuildings3d.3d/v1/20250501/11/799/503.b3dm

Metadata

The tileset.json file describes the available set of tiles. It can be used directly by CesiumJS.

https://3d.geo.admin.ch/<LayerName>/<Version>/<Time>/tileset.json

f you always want the most rectent cesium tiles, you can leave /<Time> away in the path towards tileset.json.

Parameter	Example	Description
Time (optional)	20250728	Date of tile generation in ISO-8601 (YYYYMMDD).
layerName	ch.swisstopo.swissbuildings3d.3d	The technical name of the 3D layer. Possible values are: ch.swisstopo.swissbuildings3d.3d, ch.swisstopo.swisstlm3d.3d, ch.swisstopo.swissnames3d.3d, ch.swisstopo.vegetation.3d
