First, from what I can see on this aerial imagery, congratulation. It is very hard to distinguish something on these pictures. What I see is not a 'highway' but more an informal track in the desert or the shortest way between point A and point B. Something that will disappear or change after the next sandstorm. Maybe try a new highway=track + tracktype=grade6 where grade6 would be defined as informal track in open area (e.g. desert); might be an average of several parallel vehicles marks ?

You can easily see 100m. The line on the map represents a route, it is not the route itself. By setting the width to 100m you allow for a person to travel anywhere within a 100m wide path and still reach the destination. OP asked for practical solutions. Drawing a dozen or so meandering paths from point A to point B is not practical. Best wishes, Andrew ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

[Tagging] Tagging 'averaged' paths in rural Mali
Hey everyone, As you may know, HOT is currently mapping infrastructure in Mali. In flat rual areas, there are some 'highways' (unpaved ground) that are very close to each other (up to ~100 meters ) that all lead to the same villages or destinations. Here is one example: http://binged.it/Y2XLqR We have generally traced these like we have with GPX without satellite; one average trace of the possible paths (since no one way is really more important thatn the others). So we would like some sort of tag to add additionally to not that in addition to being a highway=whatever this road is not a simple centerline, but rather just an average and you shouldn't try to follow it exactly (or necessarily expect to be able to follow it exactly). As Andrew Buck in #hot noted, 'they are useful for understanding the level of economic development in the area since they are sometimes caused simply by the lack of someone actually building road (although in most cases it just doesn't even make sense to build one)'. Do you have any suggestions of how to tag these ways ? Regards, will ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Do you have any suggestions of how to tag these ways ? IMHO in first approximation it would be OK to simply draw one of these (to create the connection, the most useful part) and eventually in a later state you could add more of them. The fact that they run parallelly doesn't mean each of them isn't a (high)way which could be mapped on its own. cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

After all, in a city with streets arranged in a grid, streets run parallel to each other, often less than 100 meters apart, and offer multiple routes to reach the same approximate destination, yet we map all of them, not an average route that doesn't correspond exactly to any of them. Now, if you were mapping footpaths separated by only a meter or two, mapping an averaged path would make more sense. -- John F.
