I just imported a GPX file into GSAK and it told me something about using an old format of GPX file. Being your typical IT worker I didn’t read it, clicked don’t show me again and clicked “OK” (Something I do far too often without thinking!)
It then got me pondering about the GPX file formats. I’d read something about the different versions before, but not worried. Basically what it boils down to is two GPX verions:
GPX 1.0 which doesn’t include attributes and
GPX 1.0.1 which does include attributes.
The GPX file that you generate from your account is determined by your settings in your account details. If you visit your ‘Manage Account Preferences’ link here, scroll to the bottom and find your GPX Version Preference you can change from GPX 1.0 to GPX 1.0.1. If you change to GPX 1.0.1 you will be able to look at and filter attributes using GSAK.
From what I’ve read it seems most modern GPS devices will support GPS 1.0.1, but won’t take advantage of it and you won’t be able to see the attributes on your GPSr. You can however use the ‘Garmin Export‘ macro to have GSAK export the attributes list as a log entry (Among other things that the macro does).
