OSM Openstreetmap tagging ADV tracks.

I wasn't planning to use it, just wanted to skim read over your source code to steal any good ideas.

The keyboard shortcuts actually make that fairly easy, once you get the hang of them. That's what I did with all my old tracks; didn't take that long.

I've already spent 50 or 60 hours doing that, and it's boring as fsck. I've got a couple thousand km's of tracks sitting in a directory, which I haven't added to OSM because it's so tedious. And there's a near-bottomless list of roads near where I live that haven't been mapped yet.

I reckon I can automate it. I've already got some of it happening with my custom iOS app, but there's more to do. At the very least I'd like to present a proposed change-set that just needs a few minor manual tweaks.

I guess my priorities are different to yours. I'm just trying to get everything on the map, and will worry about accurate tagging and the like at some later date (or let someone else do that part).

I wanna be able to show my buddy a great riding area on an actual map, instead of satellite photos... and in more remote areas, I want a bit more confidence to calculate how much fuel I'm gonna need, etc. I don't much care how difficult it is, because I can take my bike anywhere!

Have you seen dualsportmaps.com? When you import a GPX into his website, he calculates your speed at every point along the track and colour codes it. It seems to work well, speed and ride difficulty are pretty closely correlated. I've found I only need to make a few minor tweaks to the auto-calculated difficulty ratings.

With the old CanVec data, it's mostly done around here, at least for me. Just a matter of improving accuracy, making the connections, and adding in the new stuff that I find. Oh yeah, and maybe a little tagging for the masses.

Ya... well... I can go anywhere too It's just that, you know, sometimes I'm not really into the tight stuff... just lazy. Well, let's say there are times when I'd rather go fast than technical

JOSM with the gpx plugin does this and, yes, I find it quite useful. JOSM is local so no need to upload to anywhere and have to worry about sharing tracks leading to my garage full of tools. The only problem is remembering if that red section was a tough go, lunch, or a pee-stop

These are three different things:

1. Owner
2. Jurisdiction
3. Maintain

1. Owner of a way/area The legally property .
2. This is mostly a area. Border. But jurisdictions can overlap or a way in a a area can fall under jurisdiction of a other junta. I know that owners rent their area to nature management associations. This is the sign you see, their websites are not always correct, because they say they own and they mean they manage. So owner and juriditions could be different.
3. Roads can be maintained by others, than the owner. I know that owners rent them to others for nothing if they maintain it. Legal agreement is laying underneath.

If you have access to all this agreements you can tag it right.

Area (closed way) and way, could not be combined in routing program, yet.

Say do not route over a unclassified highway inside a villageborder, but use unclassified ouside the village border.
Because mostly village/town unclassified highway are tagged wrong, must be residental.
It is no fun riding your 4x4 through a residential area.

None of those wiki links strike me as slam dunks for how Forest Service roads should be tagged/relationed in order to show that they are specifically NFS roads, and I haven't found any solid examples that help me to grasp it.

Thanks for the help, though!
