I usually visualize this kind of test data with Google Earth and a few in-house tools. They work, but the workflow is fiddly and difficult to reuse or share.

As an experiment, I gave Claude Code two time-aligned KML tracks—reference and test—and built a Python pipeline to calculate horizontal error, visualize positioning status, and render everything as an animated video.

It came together much faster than expected. The script still needs cleanup, but I may turn it into a reusable skill and share it if others find this useful.

Curious how people here visualize reference-versus-test GNSS tracks, especially when RTK status or dead reckoning changes during a run.
