DashWare and TCX Files

I noticed some of you are using DashWare by ChaseCam to make cool data overlays on your bicycling videos. I'm trying to make your lives easier. You currently have to go through some pains to get your TCX data imported, so I have added TCX (and GPX) import capabilities that will be there in our next DashWare release. We convert to CSV on the fly.

I need some more test data, so if any of you could send some TCX and/or GPX files to me that would be very helpful. Also, if any TCX DashWare users want to help beta test it, that would be great too. It's one thing to look at someone else's data, but if you are intimately familiar with your own data you will notice issues easier than me.

The TCX documentation I have found is not very complete, and I gather some of the fields (e.g. Watts) are considered to be extensions to the format. Right now I am pulling in the following data items:
Time,Lap,Latitude,Longitude,Altitude,Distance,HeartRate,Cadence,Watts

I get these values from the XML as follows (omitting many fields that I ignore, for the sake of simplicity):

Code:

<TrainingCenterDatabase xmlns="https://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2"
  xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="https://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2
  https://www.garmin.com/xmlschemas/TrainingCenterDatabasev2.xsd">
  <Activities>
    <Activity>
      <Lap StartTime="2010-04-29T01:01:35Z">
        <Track>

          <Trackpoint>
            <Time>2010-04-29T01:01:36Z</Time>
            <Position>
              <LatitudeDegrees>34.432264</LatitudeDegrees>
              <LongitudeDegrees>-119.864785</LongitudeDegrees>
            </Position>
            <AltitudeMeters>23.276</AltitudeMeters>
            <DistanceMeters>5.254</DistanceMeters>
            <HeartRateBpm>
              <Value>94</Value>
            </HeartRateBpm>
            <Cadence>49</Cadence>
            <Extensions>
              <TPX xmlns="https://www.garmin.com/xmlschemas/ActivityExtension/v2">
                <Watts>247</Watts>
              </TPX>
            </Extensions>
          </Trackpoint>

        </Track>
      <Lap StartTime="2010-04-29T01:01:35Z">
    </Activity>
  </Activities>
</TrainingCenterDatabase>

I also have DashWare calculating the speed based on the GPS movement over time. I have not added a Slope Calculator yet, but this is also possible.

Thanks,
Rolf

Hi Rolf, you and I talked a bit on the dashware forums and I sent you some files. I still have your email address and can send you some more if you like. I also pointed the Ride Video Thread this way in case any of those people that had subscribed are interested.

Btw, the improved interpolation has worked well but I haven't finished any videos with it yet. My last race that I used the camera was in between a bunch of buildings and the GPS speed is all wonky.

Steve,

Thanks for that. I have it working great with your provided data. I just want to make sure it works with data from other cycling loggers if they format it slightly differently. I would like to try and make it work with pretty much everything out there if possible.

Thanks,
Rolf

I tried Dashcam last night for the first time with my Garmin data and failed to successfully create a project after trying to copy the data into the columns of an existing file. I have .tcx files files if you want them.
