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.

Hello Tony and Gareth,
Thanks for your thoughts.
My main thought was a specialised JOSM plugin - I did take a look at
OSM's main GPX trace facility but it appears not to preserve tags in
the uploaded trace. Some versions of the MapThePaths app (the first
version, and the current version on Gitlab) allow GPX upload to OSM
but the tags are removed.
So I'm thinking that my own storage (I have quite a bit of available
storage) and a custom JOSM plugin, which, for example, creates
colour-coded and clickable traces showing the ROW designation, surface
and highway tags might be the way to go.
Thanks,
Nick

I wonder if it would be possible to use the GPS trace feature on OSM
for this? Maybe format the name in a way to make it easier to retrieve?
Takes care of the storage of the traces.

Hi Nick
I like the two stage approach - surveying then mapping. It would work
well - some of my friends like walking but can't map to save their
life, whereas I can't walk far but love mapping - Win Win for us all.
May I suggest that a layer be created for JOSM with all the paths and
their details as provided for MapThePaths. Personally I find it
easier to work with JOSM and I have learnt to create a style to
highlight PROW's, but I don't know how to create a JOSM layer.
Separate layers would allow us to manually transfer from PROW layer
to MAP layer thus avoiding the mechanical import rules, and would
allow us to manually conflate where a path is already mapped but PROW
data is absent.
A layer containing the surveyed GPS data so that all the sources we
need are available would be awesome.
I may be asking for a workflow that is close to existing, if that is
the case I am able to test and document the workflow for the UK wiki
if that would be helpful.

Oops... sorry one or two editing errors in the last paragraph.
I meant to say:
"They [the non-expert user] select ROW type and path surface via a
nice interface, and then a tagged GPX trace is generated, *with
trksegs tagged with ROW designation and surface* (which was done by
the first version of the app anyway). This is then uploaded to the
MapThePaths server, and volunteer expert users *are alerted*. Said
expert user then downloads the GPX trace and, *using the tags in the
trksegs of the GPX* then edits in JOSM, perhaps via a JOSM plugin -
or even directly in the MapThePaths web app. (I am possibly thinking
of adding way creation into the MapThePaths web app anyway, time
depending)."

Hi,
Just to continue with the theme of rights of way mapping, I've been
noticing that there are still large tracts of England and Wales away
from the 'honeypot' areas with little or now ROW mapping at all
meaning there's still quite a big job to be done.
As you may remember I have been developing a companion app to
MapThePaths. In the first version of this (around two years ago) I
experimented with auto-converting GPX traces to OSM ways. However I
was dissatisfied with the results, the ways generated were really
rather nasty and I ended up having to prettify them significantly in
JOSM afterwards, rendering the auto-creation facility a little
pointless. Consequently later versions of the app have focused on
merely presenting the council and OSM data overlaid (like the
website), with only limited editing facilities, to change the
designation of a path.
However (and I may have mentioned this before, it's been a while) I
am wondering about a 'two-user' approach in which a new user merely
does the GPX survey, using an easy to use UI (a refined version of
the MapThePaths app with the UI re-designed by someone more versed
in UX than myself).
They select ROW type and path surface via a nice interface, and then
a tagged GPX trace is generated (which was done by the first version
of the app anyway). This is then uploaded to the MapThePaths server,
and volunteer expert users. Said expert user then downloads the GPX
trace and then edits in JOSM, perhaps via a JOSM plugin - or even
directly in the MapThePaths web app. (I am possibly thinking of
adding way creation into the MapThePaths web app anyway, time
depending).
Any thoughts?
Thanks,
Nick
