Hi,

When I uploaded my GeoJSON contour line into the Cesium Ion,  
It showed it like this:

This is what I expected,

Is there any way to solve this?

Ultimately, I would like to overlay it upon my point cloud like this on by CesiumJs,

Thank you in advance.

KML is giving me a 2D image

Hi! Can you send the asset id of the GeoJSON and KML files to [support@cesium.com](mailto:support@cesium.com)?

For the KML asset:

- To see elevation, please add a terrain provider. For instance, you can add the Cesium World Terrain with the code below

```auto
var viewer = new Cesium.Viewer("cesiumContainer", {
  terrainProvider: Cesium.createWorldTerrain()
});

```

Here is what the file looks like after adding world terrain:

The elevation is still off. This might be caused by unsupported tags in the KML file. If you open the asset in [Sandcastle](https://sandcastle.cesium.com/?src=Hello%20World.html&label=Showcases&code=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), you can see in the console an error saying “Placemark Regions are unsupported”. CesiumJS currently does not support Placemark tags. You can read more about KML support and roadmap here: [KML Support · Issue #873 · CesiumGS/cesium · GitHub](https://github.com/CesiumGS/cesium/issues/873).

I am still looking into the GeoJSON file. I will get back to you soon.
