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),

Use 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	20201203	Date of tile generation in (ISO-8601).
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/v1/20201203/7/136/98.terrain?v=3924.0.0

Metadata

The layer.json file provides metadata that describes the availability and structure of the terrain tiles at a given timestamp.
