@zverik the biggest problem with highway mapping (since you mention 90 km/h) is interpolation for me: the GPS just doesn't update frequently enough to place the exact point where this emergency phone or camera exists
Does the JOSM plugin do that when you import the gpx track and timestamp?
@luc You noticed the problem exactly: GPS often logs points just once a second. That's why NanoLog makes a separate list of timestamps. When paired with a GPS track, you use that only as a line with a few fixed points.
But NanoLog points, you can move back and forth with a centimeter precision, using visible bridges and road markings for georeferencing.
I frankly don't remember the state of the plugin. I think I got it to move the points, liked what I saw, and jumped to another project :)
