As such, they're usually either perpendicular to the prevailing winds, or run along the edge of someone's property line. Occasionally they're planted for shade purposes, in which case they run east-west. Tree rows planted parallel to a road are uncommon. "tree_row" as an attribute of a road might make sense, in the same way as "sidewalk" tags do. As a replacement for "natural=tree_row", it excludes a lot of the existing uses. -- Mark _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
