Frequently asked questions

How are Activities and Laps handled?

Each Activity becomes a track feature, with Lap ranges and summaries kept in the common model.

What happens to Trackpoints without a position?

Trackpoints without Position cannot align with geometry, so they are warned about and dropped.

Are TCX extensions supported?

WGS84 2D and 3D coordinates are supported. Unsupported TCX extensions are warned about and dropped.
