Flags files with missing, flat or unusable elevation information.
Finds repeated coordinates that can bloat files or affect route quality.
Looks for big jumps between neighbouring points that may indicate route errors.
Calculates route distance in kilometres and miles from the GPX track points.
Highlights sudden elevation jumps that may make ascent figures unreliable.
Checks whether the route looks like a loop or a point to point route.
Shows which issues may be safely repaired, including duplicates, missing elevation and GPX cleanup.
