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

Hi
I had the Lancashire KML file handy (as you do), looked up JOSM import
and found the OpenData plug in. Dropped the KML file onto the plug in
and it created a lancashire.kml layer with all of the ways on the layer
and the kml fields as tags.
When combined with OSM data and ESRI imagery it provides a really useful
view of the footpaths. I have a paint style which picks out some PROW
types which allows me to see what is in osm and what isn't. So I can do
some manual editing.
From the kml layer I have all the data to determine the Parish, Type &
PROW ref - that is manual tag editing.
This view does allow me to see existing paths and PROW's and manually
determine what mapping I can do.
Overlaying kml onto the imagery has already helped me to see a path I
was confused about - where it actually went. I'll be able to go out and
survey soon.
JOSM in the Edit dropdown has a Merge layer capability - I think this
should be avoided at all costs as that would constitute an unmanaged
data import of the whole of the KML file - an OSM disaster.
Adding a GPS layer will make this an awesome toolkit.
