Adding raw GPS to Ion story

Hi all,

I have simple timestamped lat/long data (and altitude) from my drone. I want to have a simple Ion story where I can view the path of the drone with a play/pause button. I have explored two options so far:

I have looked at the time dynamic data tutorial, but that requires either KML or CZML data. I could not find great resources for how to use the CZML writer to convert simple lat/long/alt to CZML. When I looked at the example CZML file, it was very complex.

Another example I looked at is in the time dynamic wheels. I don’t care about the wheels, but it seems that it simply interpolates the truck’s position between two coordinates. However, I don’t see how to convert GPS to some arbitrary coordinates.

Any help is greatly appreciated!
