[Talk-GB] Composite mapping (OSM and OS, PRoWs etc)

[SK53]

Can I add my enthusiasm for this style to that of Richard.

Some detailed points about the cartography, with examples taken from around
Capel in Surrey (TQ1740 for quick reference):

   - *Hedges *& other barriers. I, like a couple of other commentators,
   find pecked lines a little confusing and perhaps a little too strong in
   comparison with the path elements. As these are only partially mapped on
   OSM they can be difficult to interpret as they stand. For instance in this
   part of Carthmarthenshire (SN4818) I mapped many hedgerows, but practical
   footpaths are more or less non-existent.
   - *Churches *in villages. A footpath goes through the churchyard in
   Capel. The War Memorial is shown, but the church is not. Unfortunately I
   don't think we ever adopted a tagging scheme which would allow spires &
   towers to be discriminated cartographically. (I realise this is a
   cartographic nightmare given the range of places of worship & density in
   towns, but they are highly useful orientation features in the countryside).
   - *Access Land*. Small narrow patches of access land dont show up very
   well. Compare the two areas in the village of Ockly (TQ1540). The
   northenmost patch is clear, but the southern patch in (TQ1539) is largely
   obscured by the roads. Similar issues can be seen along the N-S road in
   Walliswood to the SW. It may be that in this case familiarity will allow
   users to read these features just fine (I'm finding I recognise them easily
   now, but last nig t I was very much WTF are the brown splodges).
   - *10km grid lines*. I'd like these slightly thicker than the 1km ones.

As for Richard's comment about access & LUA. Andy Townsend (SomeoneElse)
has a LUA style which performs exactly those kind of transformations.
https://github.com/SomeoneElseOSM/SomeoneElse-style. Of course it
incorporates a lot of other stuff too.16

Although showing both OSM paths & official designations can result in some
busyness I cant see any obvious alternative. The area around Ockley Station
(TQ1640) shows several examples: path running S next to railway line (the
official route obviously goes through someone's garden), further W a
bridleway runs across an area of grassland in the official data but on the
ground it goes round the edge (I looked twice). For the most part these
discrepancies will be reduced or, in the future, we'll find a way to
represent this either in OSM or elsewhere (for instance Robert Whittaker's
PRoW tracking site).
