Duplicate points in KML LineString output?

[Simon Dakin]

Apologies if this has been covered before; I couldn't find a way to
search the mailing list archives so that is certainly possible.

I'm using Ubuntu which has been recently upgraded to 11.10 which has
gpsbabel version 1.42.

I've used gpsbabel in the past (possibly with a version prior to 1.42)
to very successfully download data from my Garmin Forerunner 305 and
load it into Google Earth using the KML format.

I now find that the KML LineStrings produced appear to have duplicate
coordinates.

Looking at the source in kml.c module kml_output_tailer there is a section:


      if (kml_altitude_known(tpt)) {
        kml_write_xml(0, COORD_FORMAT "," COORD_FORMAT "," ALT_FORMAT "\n",
                         tpt->longitude, tpt->latitude, tpt->altitude);
       } else {
         kml_write_xml(0, COORD_FORMAT "," COORD_FORMAT "\n",
                          tpt->longitude,
                          tpt->latitude);
       }
     if (kml_altitude_known(tpt))  {
      kml_write_xml(0, "%f,%f,%f\n", tpt->longitude, tpt->latitude,
                                     tpt->altitude);
     } else {
      kml_write_xml(0, "%f,%f\n", tpt->longitude, tpt->latitude);
     }

which would appear to be responsible.

Anyone else concur?

If this is the culprit would it be possible to correct? I'd prefer not
to have to build the package myself just for it to automagically
appear in the Ubuntu Update Manager because I'm lazy.

TIA,
Simon

Known bug in 1.42.  Fixed in the beta and thus the next release.

Yep.  That's the code that's fixed.

Ubuntu will presumably eventually pick up the fix.
