# 3D Tiles

This service provides 3D tiles through a RESTful API, implementing the [Cesium 3D Tiles specification](https://github.com/CesiumGS/3d-tiles).

<ApiCodeBlock url="https://3d.geo.admin.ch/<LayerName>/<Version>/<Time>/<Z>/<X>/<Y>.b3dm" method="GET" />

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 | 20240501 | Date of tileset generation in (ISO-8601, e.g. YYYYMMDD) |
| Z | 7 | Zoom level |
| X | 54 | Tile column index |
| Y | 21 | Tile row index |

A 3D tile request for swissBUILDINGS3D dataset:

```http
curl -o demo.b3dm https://3d.geo.admin.ch/ch.swisstopo.swissbuildings3d.3d/v1/20240501/7/54/21.b3dm
```

## Metadata

The `tileset.json` file describes the available set of tiles.
It can be used directly by [CesiumJS](https://github.com/CesiumGS/cesium).

<ApiCodeBlock url="https://3d.geo.admin.ch/<LayerName>/<Version>/<Time>/tileset.json" method="GET" />

| Parameter | Example | Description |
| --------------- | -------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Time (optional) | 20201203 | Date of tile generation in (ISO-8601). |
| 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` |

A metadata request for the Vegetation dataset:

<ExampleCodeBlock
request="curl https://3d.geo.admin.ch/ch.swisstopo.vegetation.3d/v1/tileset.json"
example='{
"asset": {
"version": "1.0",

# Terrain Service

This service delivers multi-resolution 3D terrain data as quantized mesh tiles, fully compliant with the [Cesium Quantized Mesh 1.0 specification](https://github.com/AnalyticalGraphicsInc/quantized-mesh).
Tiles are organized and served following the [Tile Map Service (TMS) specification](http://wiki.osgeo.org/wiki/Tile_Map_Service_Specification) using a global-geodetic profile (latitude/longitude coordinates),

<ApiCodeBlock url="https://3d.geo.admin.ch/ch.swisstopo.terrain.3d/<Version>/<Time>/<Zoom>/<X>/<Y>.terrain" method="GET" />

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:

```http
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.

<ApiCodeBlock url="https://3d.geo.admin.ch/ch.swisstopo.terrain.3d/v1/<Time>/layer.json" method="GET" />

| Parameter | Example | Description |
| --------------- | -------- | ------------------------------------------------------------------------------------------------------------------------- |
| Time (optional) | 20201203 | Date of tile generation in (ISO-8601). If no date is provided, it returns the metadata for the most recent terrain tiles. |

Example of a metadata request for the date `20201203`:

<ExampleCodeBlock
request="curl --compressed https://3d.geo.admin.ch/ch.swisstopo.terrain.3d/v1/20201203/layer.json"
example='{
"attribution": "Put something there",
"available": [...],
"bounds": [-180, -90, 180, 90],
"description": "Nice terrains",
"format": "quantized-mesh-1.0",
"minzoom": 0,
"projection": "EPSG:4326",
"scheme": "tms",
"tilejson": "2.1.0",
"tiles": ["{z}/{x}/{y}.terrain?v={version}"],
"version": "3924.0.0"
}'
/>
