**Is there any way to create a url pointing at the cesium viewer with a kml file link that will open automatically?**
**Something like**

**Can’t find a way to embed the viewer in to Google Sites so just want to use a link for now.**
**Thanks**

I did this on my python Flask server using jinja 2 templating. I just pass the reference to the kml file as KMLFILE as a KmlDatSource.:
{% if KMLFILE %}
viewer.dataSources.add(Cesium.KmlDataSource.load(’{{KMLFILE}}’,options));
{% endif %}

I don’t see the problem then. You should be able to add a KML Data Source using:

Mmm not sure if I have explained properly Jesse. This is what I am doing manually, but I just want to be able to do it with a single url I can send to someone to click on.
I currently click on this link to open the Cesium Viewer in Google Chrome
[http://cesiumjs.org/Cesium/Build/Apps/CesiumViewer/index.html](http://cesiumjs.org/Cesium/Build/Apps/CesiumViewer/index.html)
Then I drag and drop this .kml file into the viewer which displays it.
[https://dl.dropboxusercontent.com/u/73681667/TheWarden/VIC/AWSNew/FWIChangeLive.kml](https://dl.dropboxusercontent.com/u/73681667/TheWarden/VIC/AWSNew/FWIChangeLive.kml)
I would like to to be able to insert the kml link into the URL as an argument
[http://cesiumjs.org/Cesium/Build/Apps/CesiumViewer/index.html](http://cesiumjs.org/Cesium/Build/Apps/CesiumViewer/index.html) [https://dl.dropboxusercontent.com/u/73681667/TheWarden/VIC/AWSNew/FWIChangeLive.kml](https://dl.dropboxusercontent.com/u/73681667/TheWarden/VIC/AWSNew/FWIChangeLive.kml)
I have zero web development experience so have to keep it simple.
Thanks

CesiumViewer looks for a “source” query parameter and loads that automatically.
So …CesiumViewer/index.html?source=whatever
List of query parameter options is in the source:
