GPX file showing unwanted straight returning line in other apps

[joeldebruijn]

Background:

• I prepare trips in OSMand Web
• After finding the right route, its exported as a GPX file.
• I save them locally for longterm archival and sometime view them in other apps (like Gnome Maps or Organic Maps).

Symptom: When opening a GPX file (made by OSMand) in another app it shows a straight returning line.

I tested it in 2 other apps and it shows. Imported in OSMand Android this line is absent though.

Questions:

• Is this an error of the other apps by showing a return line?
• Is there something wrong in the produced GPX files?

Hi @joeldebruijn

I created the GPX file on the web Sat Jul 20 2024 - 2.gpx.zip :

After I opened this file by OsmAnd:

Tapping to "Plan a route" tool opens this route with Profile with OsmAnd and preparing route:

This file has two types of tags inside :

1. - route segment: it's a straight lines on your example:

  <rte>
    <rtept lat="51.4595155" lon="19.7813988">
      <extensions>
        <osmand:profile>bicycle</osmand:profile>
        <osmand:trkpt_idx>0</osmand:trkpt_idx>
      </extensions>
    </rtept>
    <rtept lat="51.4452346" lon="19.8312664">
      <extensions>
        <osmand:profile>bicycle</osmand:profile>
        <osmand:trkpt_idx>43</osmand:trkpt_idx>
      </extensions>
    </rtept>
    <rtept lat="51.430093" lon="19.8674011">
      <extensions>
        <osmand:profile>bicycle</osmand:profile>
        <osmand:trkpt_idx>55</osmand:trkpt_idx>
      </extensions>
    </rtept>
    <rtept lat="51.4104495" lon="19.8491192">
      <extensions>
        <osmand:profile>bicycle</osmand:profile>
        <osmand:trkpt_idx>75</osmand:trkpt_idx>
      </extensions>
    </rtept>
    <rtept lat="51.3934756" lon="19.8487759">
      <extensions>
        <osmand:profile>bicycle</osmand:profile>
        <osmand:trkpt_idx>144</osmand:trkpt_idx>
      </extensions>
    </rtept>
    <rtept lat="51.3726377" lon="19.8429394">
      <extensions>
        <osmand:profile>bicycle</osmand:profile>
        <osmand:trkpt_idx>282</osmand:trkpt_idx>
      </extensions>
    </rtept>
    <rtept lat="51.352916" lon="19.8306656">
      <extensions>
        <osmand:profile>bicycle</osmand:profile>
        <osmand:trkpt_idx>344</osmand:trkpt_idx>
      </extensions>
    </rtept>
  </rte>

2. classic point-to-point

   - with point segment with coordinats and elevation in our case:

 <trk>
    <trkseg>
      <trkpt lat="51.459559" lon="19.7814786">
        <ele>201</ele>
      </trkpt>
      <trkpt lat="51.4591662" lon="19.7820264">
        <ele>201</ele>
      </trkpt>
      <trkpt lat="51.4591428" lon="19.7820586">
        <ele>199.7</ele>
      </trkpt>
      <trkpt lat="51.4591161" lon="19.7820157">
        <ele>201</ele>
      </trkpt>
      <trkpt lat="51.4587768" lon="19.7824985">
        <ele>200.2</ele>
      </trkpt>
      <trkpt lat="51.4558053" lon="19.7865567">
        <ele>201.8</ele>
      </trkpt>
      <trkpt lat="51.455476" lon="19.7869912">
        <ele>201</ele>
      </trkpt>
      ............

The Komoot app can open one or second variants:

choosing of variants

But the Organics maps app opens as you wrote with a mix:

Oh thnx for reproducing and sharing this, never new GPX could have these 2 "types of Tour". 🙏

Is there a way for OSMand to generate with only point-to-point and without route segment?

Otherwise I make an issue for Organic Maps to treat GPX import the way Komoot does.

While you can do it on the OsmAnd App Open track menu > Plan a route button (Edit track) > Opitons > Save as new track > choose the "Simplified Track" option and save it. and only after that this track will be have only point-to-point

[joeldebruijn]

Your explanation helped me looking into the GPX standard, learned about rtept en trkpt differences. eg https://gis.stackexchange.com/questions/403664/how-route-points-rtept-and-track-points-trkpt-can-exist-in-a-gpx-file-togeth

I was inclined to close this issue and make a new one, asking for the "Simplefied Track" option for OSM web. Preferably somewhere here:

But I dont know if OSMand web is meant to have the same features as OSMand Android/iOS? Because then the backlog for web becomes huge I guess?

@joeldebruijn Yes, it's a good decision to make a new issue. Please, create it here. yesterday we had a short discussion about this case and the "Simplified track" is needed for the Options list.
