[Talk-us] Labeling forestry service roads/tracks

[brad]

Thanks for diving in.   If it's a very minor unimproved road and not 
clearly service, I usually tag it track.   I would suggest adding some 
indication of road quality.   If it's an improved gravel road, I 
consider surface=gravel sufficient.   If it's rougher than an improved 
gravel road, surface=unpaved (in my area the surface is usually a mix of 
dirt, rocks, gravel, so unpaved seems best),   and smoothness=very_bad 
(high clearance), or horrible (4wd) 
[https://wiki.openstreetmap.org/wiki/Key:smoothness], or 4wd_only=yes .

The USFS motor vehicle use maps (MVUM) are very useful.

I think most of the road signs say FS, and most of the tags in my area 
use FS, but the wiki 
(https://wiki.openstreetmap.org/wiki/United_States_roads_tagging#National_Forest_Road_System) 
says to use FR .   I don't know the history, or if it really matters.  
If someone is reading a map & it says FR or FS, they probably won't even 
notice.

Keep this in mind when getting frustrated with the tiger data, I think 
we would have next to nothing if it didn't get imported.
