Re: [Gpsbabel-misc] Getting tracks out of a .gdb file

[Adam S. <ada...@un...>]

Update: I've since figured out that the "tracks" in this renegade .gdb file are actually stored inside the routes... which doesn't make a whole lot of sense to me.  But if the file is saved from Garmin Mapsource as a GPX file, the routepoints look like this:

    <rtept lat="34.3881717" lon="-118.4782657">
      <time>2007-03-24T18:15:37Z</time>
      <name>Hwy14</name>
      <cmt>Hwy 14</cmt>
      <desc>Hwy 14</desc>
      <sym>Waypoint</sym>
      <extensions>
        <gpxx:RoutePointExtension xmlns:gpxx="http://www.garmin.com/xmlschemas/GpxExtensions/v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.garmin.com/xmlschemas/GpxExtensions/v3 http://www.garmin.com/xmlschemas/GpxExtensions/v3/GpxExtensionsv3.xsd">

          <gpxx:rpt lat="34.3886435" lon="-118.4788168">
            <gpxx:Subclass>010012b74f00165f080021160000900a9000</gpxx:Subclass>
          </gpxx:rpt>
          <gpxx:rpt lat="34.3893099" lon="-118.4779787"/>
          <gpxx:rpt lat="34.3905544" lon="-118.4758759">
            <gpxx:Subclass>010012b74f00165f08021f000b001d466d16</gpxx:Subclass>
          </gpxx:rpt>
          <gpxx:rpt lat="34.3905544" lon="-118.4758759"/>
          <gpxx:rpt lat="34.3907261" lon="-118.4755754"/>
          <gpxx:rpt lat="34.3944597" lon="-118.4687090"/>
          <gpxx:rpt lat="34.3953609" lon="-118.4671211"/>

...and so on.  It seems the actual GPS position may have been stored in there.  I've updated GPS Visualizer to read these extra points properly when they appear in a GPX file, but is anyone from the GPSBabel team working on this weirdness in the binary files?

One more bit of fun: the schema's URL, as given in the gpxx:RoutePointExtension tag, gives a 404 error!
