Error in uploading .kml file

Hello, I am attempting to upload an asset to Cesium Ion account but keep getting message that the file must be .kml/.kmz. and that .kml, .kmz, .czml, and .geojson files must be uploaded individually.

The file I’m trying to upload is a .kml that i created from Google Earth Pro. I haven’t had this issue in the past.

Please advise.


Hey Eric,

Is this dataset composed of 3D buildings, with COLLADA models inside your KMZ?

If you, you need to select “KML/COLLADA (tile as 3D Tiles)” when uploading to Cesium ion. If that doesn’t work, let me know the asset ID and we can investigate from our side.

Omar, Thank you for the quick response. :slight_smile:

The .kml is a very small(4kb) .kml tour file that simply zooms in on a location. No 3-d buildings.
I am not able to give you an asset ID since i cannot get the ion UI to actually upload the .kml file to completion.
I could send you a screenshot perhaps. My email address is

Kind regards,
