Can I use the default in-web editor to create or edit a GPX file without actually changing the map?
Upload the file, make it a way, drag nodes to the path in the aerial image, then download the way in GPX format and exit without saving?
If not, is there a useful tool to accomplish this?
I took photos on a long bike ride and extracted GPX from the photos, so the lines go straight from point to point instead of following the curves in the path. I had a tracking device, but apparently I did not have it on during that ride.
JOSM triggered a problem in my MacBook that Apple has yet to admit is there (other things also trigger it, so it’s not JOSM’s fault). BRouter not only does most of my work, it allows me to add the missing end of the route. However, I can’t figure out how to stop extending and edit a node within the way, or to extend the beginning of the way. Also, even though I selected a profile that was NOT the one avoiding stairs, when I tried to go up the stairs at the end, it chose an extra kilometer to go around!
But I can manually edit the GPX to do the last bits of the trek.
To stop appending press “Esc” key or toggle the pencil button on the left (blue when active). You can also move a marker or drag the route to create a new via point while in append mode.
Appending only works at the end, but you can reverse the route (R key or button with crossing arrows) to make the start the end, append, and reverse again afterwards.
The default Trekking profile still has a cost factor (penalty) of 40 for steps, even when allowed, so it prefers a detour that is up to 40 times longer than the steps section, e.g. 400 m for 10 m steps:
if ( highway=steps ) then ( if allow_steps then 40 else 10000 )
