OSMDoc currently lists 619 surface values (http://osmdoc.com/en/tag/surface/#values) - wasn't sure how to get this info from TagWatch. TagStat is also enlightening: http://tagstat.hypercube.telascience.org/tagdetails.php?tag=surface 470 instances of "surface=Dirt Road". 1604 "interlock". At a quick glance, the list of items in the wiki bears little resemblance to the top 20 or so items in TagStat. surface=ice_road?? >You see, mappers actually want their data to be useful. Defining standard types with clear definitions and semantics, and cleaning up old data to conform to those specifications is a good way to assist this.
