Power Data Recorded But Inaccessible

GoogleCodeExporter commented 9 years ago

My Tracks records power data from the SRM PCS7. This can be seen live on the 
sensor screen and it is stored in the database but there is no way to extract 
it. Ideally it would be included in the TCX and perhaps GPX exported data files.

The power data is available on the chart and in the TCX file.

So it is. It is encoded as an activity extension which I missed. Cadence is 
also in the extension. Cadence should be included in the trackpoint as 
described at

The problem with including cadence in an extension is that most places you can 
upload the data cadence will not be recognised if encoded this way. Here is an 
example trackpoint from a TCX export where HR, cadence and power were recorded.

<Trackpoint>
          <Time>2012-02-22T22:41:28.0Z</Time>

            <LongitudeDegrees>175.779932</LongitudeDegrees>

        </Trackpoint>
