[gdal-dev] including higher-level library in GPX creator string

[Greg Troxel]

I am a member of the GPX standards list, and we are discussing a new
version and also dealing with broken data.

I wrote a gpx (from geojson), with just ogr2ogr, and the creator looks
like this:

  creator="GDAL 3.5.3"

that's arguably totally fine with ogr2ogr.

But it seems that if some random big program links with gdal and uses it
to produce a file, the creator is just GDAL, and not "qgis 3.28.5 via
GDAL 3.5.3" or something like that.  I groveled over all my gpx files
and found none that indicated anything like this.

It would be helpful to the GPX community if files were attributed to the
larger software as well, so that they can be chased down or at least
understood to be separately broken.

I don't see anything at
  https://gdal.org/drivers/vector/gpx.html#vector-gpx
that could be used to do this.

Does this make sense to people here?

Is there any facility that would do this, that people just aren't using?

Any other thoughts?
