Multiple gpx files allowed?

Preliminary notes:
1-My head includes:
cesium.com/downloads/cesiumjs/releases/1.91/Build/Cesium/Cesium.js
cesium.com/downloads/cesiumjs/releases/1.91/Build/Cesium/Widgets/widgets.css
2-I have only a few landscapes, so I upload the gpx file direct from my site.

I am not good in creating CESIUM scripts, so I asked an artificial intelligence (AI) site to solve my problem, but the AI site was not succesfull.
My problem and my request is: how must I place two gpx files into a script?
In my case: away as gpx-1 and back as gpx-2.

Thx in advance for your hints,
Josef

Hi @cverwalter, thanks for the question!

CesiumJS supports gpx data through the GpxDataSource object. We have an example of loading data this way in this Sandcastle.

Hopefully that’s enough to get you started but please let me know if you’re still having issues
