I’m trying to add surface tags to the highways in my area. I can see highways that are tagged unpaved on the map however highways tagged as paved and untagged highways look the same on the map to me. Is there a way to find out which highways or sections of highways are untagged without checking all of them for tags in JSOM?
In JOSM, View->Map Paint Styles ->Surface or Surface - Data Entry
(More Map Paint Styles can be added from Preferences->Map Settings->Map Paint Styles)
