##### Cesium Ion terrain provider

The `terrain` layer of the `cesium-ion` type enables the use of Cesium Ion terrain format-compliant services (i.e., Cesium Ion resources). The options attribute allows for the configuration and access of Ion resources and their associated assets.

```json
{
"type": "terrain",
"provider": "cesium-ion",
"visibility": true,
"options": {
"assetId": "", // cesium ion asset id to be requested (mandatory)
"accessToken": "", // cesium access token to be used (mandatory)
"server": undefined, // resource from the Cesium ion API server. Defaults to https://api.cesium.com when unspecified
"credit": "" // optional, additional credit to be displayed along side credit and attribution from ion resource
}
}
```

#### Elevation

This layer provides information related to elevation based on a provided DTM layer. **It does not provide the terrain profile for 3D visualization**, see [terrain](#terrain) layer type for this feature.
