#9 Elevation is saved as mtk:speed from Holux GPSport 245

[Paul]

Hi,

When extracting gps data from my Holux GPSport 245 the elevation is saved as mtk:speed extension in the GPX file:

<trkpt lat="50.104331970" lon="8.649784088">
  <ele>0.000000</ele>
  <time>2013-06-12T09:31:07Z</time>
  <extensions>
    <mtk:wptExtension>
      <mtk:speed>38.371094</mtk:speed>
    </mtk:wptExtension>
  </extensions>
</trkpt>

While this is the output from Holux's ezTour Software:

<trkpt lat="50.104331970" lon="8.649784088">
    <ele>38.371597</ele>
    <time>2013-06-12T09:31:07Z</time>
    <speed>0.190000</speed>
    <extensions>
        <speed>0.2</speed>
        <temp>0.00</temp>
        <bpm>0</bpm>
        <rpm>0.00</rpm>
    </extensions>
</trkpt>

While the coordinates are identical, the speed/ele-number is almost identical: 38.371094 == 38.371597.

The speed does not seem to be read.

It works switching speed and height reading:
