@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 :)
