OpenStreetMap
Llanollen Canal
Posted by NorthIsland on 25 September 2017 in English. Last updated on 12 February 2019.Went along the Llangollen Canal this year and surprised that there was very little landuse on OSM. Based on memory and aerial photo, I am working my way from Llangollen to Ellesmere. Perhaps this will inspire more to visit! On the Farmland/Meadow issue, I tend to map according to ground colour. I follow those who think that Farmland is crops and Meadow is for grazing. meadow could be ploughed. If you can see worn tracks, lots of individual trees, growth variation, or steep slopes, then it’s probably meadow. Still waiting for someone to come up with a rendering for Fell….

To be honest, I wouldn’t worry too much about “very little landuse”. It’s actually easier to add other features (POIs, hedges, ditches etc.) before landuse has been mapped, and if you’ve surveyed all the hedges etc. adding landuse is also much easier.
There has been a bit of a problem in GB with “remote upland mapping” - people wanting to “colour in” landuse and making a bit of a mess of it, either by drawing very rough landuse boundaries (far less accurate than the existing work that people have done) or by just “getting it wrong” - picking something rendered by the OSM Carto stylesheet (“heath”) regardless of whether the thing they’re mapping is remotely heathland, or even “heathland in OSM terms”, or not. https://lists.openstreetmap.org/pipermail/talk-gb/2017-September/thread.html#20643 is one thread on talk-gb, but not the only one, as it’s been an ongoing issue.
As to what thing on the ground matches what “natural” OSM tag, that’s probably one for the mailing lists - https://lists.openstreetmap.org/pipermail/talk-gb/2017-September/020645.html is an attempt to map existing non-OSM classifications as a basis for this.
With regard to “ Still waiting for someone to come up with a rendering for Fell” why not have a go yourself? If you want “a slippy map like the OSM website” then if you follow https://switch2osm.org/manually-building-a-tile-server-16-04-2-lts/ you’ll get one (see also https://ircama.github.io/osm-carto-tutorials/ ), and modifying that to say “treat natural=fell like natural=heath, but with a slightly different colour” would actually be pretty straightforward.
What is slightly complicated is that natural=fell is actually used for a variety of features (see http://overpass-turbo.eu/s/rX4 ) so you might need to do a bit of head-scratching to see if you wanted to also include a special “fell” rendering for https://www.openstreetmap.org/way/518304766 or https://www.openstreetmap.org/node/773534919 .
