StephanKN asked me to upload the tracks from which I am currently mapping in Thailand. I spent a little time on that today, cleaning out all waypoints and tracks drawn by hand or “saved” by my old GPS. To my great surprise OSM accepted all 1775 tracks and ignored all the points without time stamps, rather than choking on them.
Somebody may want to have a go at re-aligning h’way 32…
