Inspect, clean and convert GPX files
A privacy-first iPhone and iPad toolbox to visualize routes in 2D or 3D, spot GPS anomalies, correct elevation, merge or split tracks, and export clean GPX, KML or CSV files.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
