I have a GPX file. It is data collected in a garmin handheld GPS.
There are several separate tracks within the file.
All looks fine when i look in MapSource or look at the raw data in the file.
When i import this file to Garmin connect website, it finds the tracks ok, however some of the time/speed data is incorrect.
For example a track lasting 5:35:29 (eg. 5 hours), shows up as 23:30:40. Of course this effects speed displayed.
In some the distance is incorrect.
Perhaps part of the issue may be that what are separate and independent tracks, are considering the relationship between tracks, the time between end of one and start of another.
Further perhaps it is not processing the tracks in the correct order, so i think this accounts for the large time values. Likewise it should not include the distance between tracks at all.
I feel it should process each track using the start/end time of the track independent of any other track in the file.
One other detail, it seems to ignore the track name, which contains useful information.
My workaround is that i separate each track into a separate .gpx file and import all these separate files.
