In addition to what Frank said, I would also like to point out that sac_scale [1] can be useful for hiking trails. If you happen to be into mountain biking, the group of mtb: tags are also useful [2]. I'm also in favour of using the smoothness tag [3] for forestry/4x4 roads, though there is debate about its usage, and I'm waiting to see if surface:condition takes over.<br>

im happy that Frank could answer your question MUCH better that i can. :)<br>
<br>
I've met a few mappers around, and yup, i'll plan for a mapping party<br>
soon, and hope that other experienced mappers will be able to attend<br>
(and host it) :-)<br>
<br>
Great to hear from you again, and yup the trail mappers around here<br>
are doing an awesome job!<br>
<br>
Hopefully in the spring i'll have my bike and be able to map out the<br>
route relations that Frank mentioned.<br>
<br>
Cheers,<br>
Sam<br>
