[OSM-talk] highway=unsurfaced

[john at jfeldredge.com]

In a prosperous country, the only roads likely to be unsurfaced are tracks, unclassified, or bridleways.  Other roads are likely to have at least a gravel surface.  However, in much of the Third World, the majority of the roads are likely to be unsurfaced, even if they are of major importance to the region.  So, no one set of assumptions will fit the entire world.

"Depreciated" means "reduced in value". You mean "deprecated", but you can
only deprecate a feature from the wiki docs, not from the database.

No. highway=unsurfaced could be what's now commonly tagged as highway=track,
or highway=unclassified, or highway=bridleway. Only one of those three is a
road.

You should create a rendering which highlights highway=unsurfaced, so that
people will find them and modernise the tagging _appropriately_ for that
specific case.
