Terrain Service
This service delivers multi-resolution 3D terrain data as quantized mesh tiles, fully compliant with the Cesium Quantized Mesh 1.0 specification. Tiles are organized and served following the Tile Map Service (TMS) specification using a global-geodetic profile (latitude/longitude coordinates),
https://3d.geo.admin.ch/ch.swisstopo.terrain.3d/<Version>/<Time>/<Zoom>/<X>/<Y>.terrainUse the following parameters to define your request:
| Parameter | Example | Description |
|---|---|---|
| ServerName | 3d.geo.admin.ch | |
| Version | v1 | v1 means terrain tiles generated with cesium tiles |
| Time | 20250101 | Date of tile generation in ISO-8601 (YYYYMMDD). |
| Zoom | 12 | Zoom level |
| X | 4309 | The longitude index |
| Y | 3111 | The latitude index |
An example of a terrain tile request:
curl -o demo.terrain https://3d.geo.admin.ch/ch.swisstopo.terrain.3d/v1/20250101/11/2130/1550.terrain?v=1.43646.0Metadata
The layer.json file provides metadata that describes the availability and structure of the terrain tiles at a given timestamp.
https://3d.geo.admin.ch/ch.swisstopo.terrain.3d/v1/<Time>/layer.jsonIf you always want the most rectent terrain tiles, you can leave /<Time> away in the path towards layer.json.
| Parameter | Example | Description |
|---|---|---|
| Time (optional) | Date of tile generation in ISO-8601 (YYYYMMDD). If no date is provided, it returns the metadata for the most recent terrain tiles. |
Example of a metadata request for the date 20250101:
curl --compressed https://3d.geo.admin.ch/ch.swisstopo.terrain.3d/v1/20250101/layer.json{
