[Talk-GB] Rights of way mapping - making it easy for newcomers to OSM (perhaps!)

Thu May 14 13:19:10 UTC 2020

It's worth pointing out that the same can be done with the following
editors: iD, Potlatch2, and Vespucci. The actual formats (gpx, kml, shape,
geojson) vary a bit, but all have the capability.

For some years I've loaded KMLs onto Maps.Me so I can actually check the
line in the field (I've made Garmin files too, but this is easier &
quicker).
