  Hi Lionel and Laurent,

  I'm very sorry for the late reply. I was on sick leave for the past few weeks and am now catching up on the forum, while the team focused on the help desk in my absence.

  I've rescheduled the regular "Bugs" meeting I have with the development team and will make sure to bring this bug to their attention again.

  @Laurent: I understand that this issue calls your premium subscription into question, and I hope the team can get to the bottom of it.

  All the best,
  Julien

  Hi
  
  Still no improvement about this distance problem that was reported by many members. 

  It'really a shame that Plotaroute, such a great tool with incredibly useful features, is now ruined by a glitch about what is a basic requirement for a route planner i.e. showing the right distance of a ride. 

  My subscripton as a Premium Member is due to expire in nine days, still wonderning whether I shall renew or not. 
  
  

  Regards

  Hello,
  I confirm there is something wrong with reported distance of uploaded & drawn GPS tracks.
  I get a roughly 2% decrease of the expected length on all tracks I upload. Not sure how this is calculated but definitely something worth checking.
  On a 100 km race that is 4 to 5 km difference...

  Hi Laurent,

  I'm sorry to say that so far, there has been no progress on this matter.

  What I can share however, is that we haven't deliberately changed something that explains why all of a sudden distances are not the same as they used to be a few months ago.

  Therefore, this sadly isn't something the devs can simply roll back, and they are still looking into what has caused this change.

  I'll make sure to update this topic as soon as I receive any news.

  Kind regards,
  Julien

  Hi 

  Distance shown on Plotaroute still very erratic, no improvement for the time being. 

  It would be so grat if your team could go back to the older system which worked pefectly fine. 

  Best regards

  Hi Laurent and Alessio,

  Thanks for bringing this to our attention and for providing examples.
  Other users got in touch with us to raise issues with distances as well.

  I have reopened the previous bug report and will discuss this with the devs again.

  I'll update this topic as soon as I receive any news.

  All the best,
  Julien

  Hello Laurent and Alessio,

  
  I'm Aurélie, one of Julien's colleague.

  
  Tech team is asking to get the GPX you are talking about to check more precisely what is happening.

  Could you please send me GPX via the help desk ? and add what are the real values you are expecting (if you know it)

   

  Kins regards,

  I also noticed that when correcting a route (for instance cutting through a roundabout for a cycling race); the distance shown which should be lower is sometimes higher - and vice versa. 

  Finally it seems the distance shown on the screen works in an utterly erratic way. 

  Like Alessio I found this is a new fault which appeared quite recently. 

  Please ask your developers to correct it as it ruins the fantastic experience we had with plotaroute.

  After further testing, it looks like that distance markers are generated correctly when exporting the kml from the website. However, route distance shown in the dashboard is not.

  I confirmed that something must have been changed recently in the way the route distance is calculated when a file is uploaded.

  I am the television producer for cycling races like Giro d'Italia and Milano - Sanremo. I always use plotaroute to reverse the route and generate km markers, before exporting the kml and adding the other information we need (points of interest, sprints, etc.). So we always have a reference of km to go that matches with the information coming from tv graphics and gps on the motorbikes.

  I used this workflow for races in March and everything worked fine. Now, the Giro d'Italia starts tomorrow, but I can't used this method anymore, and this is very frustrating. I am experiencing differences up to 4 or 5 kms in the route distance.

  Please get the algorythm back where it was!
