Re: [Gpsbabel-misc] Garmin .gpx to Mapfactor Navigator .xml help wanted

[Robert L. <rob...@gm...>]

Thank you, Peder.

This has now been committed in
https://code.google.com/p/gpsbabel/source/detail?r=4794
https://code.google.com/p/gpsbabel/source/detail?r=4795

I'm calling that out as an example of basically how easy it is to add an
"easy" format, once it's understood; it's pretty boilerplate. Here, the
hardest part was the discovery that they used milliarcseconds.

I found and fixed the bogus character encoding, as you can see in the
mapfactor~gpx.gpx reference file.  Your wish for supporting "groups" was
rejected as it's not a concept that maps well to other formats and we're
more about getting your data in and out of other programs than about
supporting every format-specific feature possible.

This will be in the next build you see from us.
