Issue KML import/export not working as expected

CesiumJS
1

Hi all,

The visualization of KML files isn’t working as expected (or as I am expecting).

Using your own example, I am able to export the CZML data (simple.czml) as KML/KMZ (Satellite.kmz)

However, when reading it into cesium.js I am not seeing the vector data being respected the same way.

Result:

Expected:

Are there any limitations with KML? Any additional properties / parameters I should be aware of?

Thanks,
-Dave

Hi there,

CZML as a format was designed to handle time-varying values beyond what is possible in KML. That design was centered around use cases like this with satellite trajectories. In the CZML to KML conversion process, one effectively loses some of that time-dynamic information. I expect this is what’s causing the discrepancy you are seeing here.

Hope that helps,
Gabby
