Hello all,
I would like to create a new track based on several tracks of a certain route, which is the average of all read-in tracks.
This would increase the accuracy of the position of the researched route.
Does anyone know of such a tool?
Thank you for your aid,
Marc
I haven’t looked into a tool to do this, but usually a smart rendering of the tracks will do the trick of showing the average. This is basically how the Strava Heatmap works
Hi Joost,
Thank you for responding to my mail.
I do not understand what you meam with “smart rendering”. I don’t know how that works.
Can you explain me more.
In the case of Strava, they turn all the many tracks into a point cloud:
While some precision is lost that way, it does show where the centerline should be in most cases.
If you have a more limited number of tracks, I would load them to QGIS and then show them all slightly transparent. Then when several tracks are rendered in the same place, you get a “denser” area. And that’s where you would expect reality to be.
Note that additionally having detailed hillshade data also helps a lot in this context:
Hi Joost,
Thank you for the precisions. I have a look with Qgis. Thats a very good idea. So i can better trace manually the line. I have also good hilshade data, but that is not very important in the case i need to work on.
Thank you for your help and have a nice week.
Best regards,
Marc
