Скачать или смотреть JOSM technique: mapping forests bounded by roads in OpenStreetMap

Demonstration of mapping rural forest areas in JOSM by re-using already mapped roads. After recording this I realized that holding down 'alt' while using Parallel mode gives you a copy without the tags of the source way and it's nodes. I wish I'd realized this before recording as it simplifies things a bit. Maybe I'll make a new version at some point.
