OK,
So we start with only natural=cliff skipped.
As I wrote above best would be a special theme/option for maps with crags
I agree.
However, I’m pretty shure that a lot of our users don’t even know that options exist in elevate and special theme would add much of confusion as long as Mapsforge can’t bind themes to maps by default.OK,

Personally I would not want to add yet another option if it can be avoided. Adjusting the map rather than the theme does make changing from one country to another rather more foolproof also.

Sorry – to be clear, that’s what I was agreeing with!

Fine,
I’m really happy with this.
Its a major step ahead for UK-Maps.
🙂
🙂Thanks @geoffmozz for starting this thread !

And I’m jealous, I’d like crags for the Alps, too 😀

The maps with OS crag data has been something I’d been hoping for for a while, thanks for implementing it!
I disagree slightly with removing natural=cliff in all instances however. On the new maps there is significant loss of detail now across many the famous climbing and beauty spots in the Peak district, as the OS opendata does not draw many crags in this area for some reason. Take for example the Roaches, it is a mile long sandstone cliff, or the impressive Stanage Edge, 3.5ish miles, both now do not show on the maps when natural=cliff is removed. It is complicated however because nearby Burbage Edge is for some reason drawn in good detail on OS opendata

Question:
Do the OS Contourlines better match reality than the Sonny/Viewfinder ones ?
🙂I believe the OS contours are more accurate, certainly around Mount Snowdon in Wales. The Sonny data has notable artifacts. Two examples attached where it smooths the side of Y Lliwedd into a triangle and not sure what it is doing to the east side. Have’t noticed anything as bad as this anywhere else though

For some reason the OS digitised data is missing the crag markings around the Roaches. The crags are shown on the traditional OS maps.
I don’t know if there are other areas where this is true or if a carefully worded email to OS would get it sorted.The maps with OS crag data has been something I’d been hoping for for a while, thanks for implementing it!

There are numerous crags and cliffs that are on OS maps and Openstreetmap that are not in the OS OpenData crag ornaments. As mentioned previously an example is Stanage Edge (which has a very small handful of markings but nowhere the detail as OS maps, definitely not drawn as a 3.5 mile cliff). Another prominent example is High Tor and Lovers Walk in the unusual inland seaside town of Matlock Bath (SK 29318 58232), as both are tourist attractions and a main sight while walking through the town, missing in OS opendata. I’m not sure the logic for inclusion or not from the data. Stanage and the Roaches are significant landscape features visible for tens of miles, minor outcrops around a tiny village called Brassington (SK 22820 54454) are drawn with lots of detail (although not particularly accurately).
Another issue removing natural=cliff is the complete loss of crag names, even in examples where the OS data does have drawings. Obviously of most use to climbers, but walkers and cyclists will likely use prominent named crags as way points or navigation aids.
I definitely think the inclusion of OS crags is great but I think natural=cliff still also needs including. I can see it looks a little unappealling in the coastal examples shown previously (maybe if coloured the same it wouldn’t look as bad), but in many other areas using OS data alone unfortunately removes entire major landscape features from the map, and countless minor crags and named waypoints
Our intention was to replace the partly very incorrectly mapped cliffs (especially near the coast) with the better crags.
Now it seems that it would be the better solution if the two data sets complement each other – especially because the crags are unfortunately not complete in all areas.So I will include the cliffs in the maps again
and
hope that the OSM mappers will check their cliffs against the crags to get more accurate OSM data.The new map set should be available tomorrow, 24 December.
Merry Christmas

We’re between a rock and a hard place here (pun intended), as with two data sets which overlap it doesn’t really matter what we do as there will always be cases where it won’t work out.
Maybe a different tag-mapping with e.g. natural=cliff_uk tag? Then one could render names without lines, or a more subtle rendering of cliffs so they are still visible but not as strong as in the rest of the world…

Hooray and hurrah. OS crag detail on the OpenAndroMaps of Britain. Well done all. An unexpected Christmas present 🙂
When I saw that John Thorn had incorporated the OS opendata crag detail into his mapsforge map of Britain I guessed it must be possible to do the same with the OpenAndroMaps….and it seems it is. Great. Thanks for putting the work in. I would have got stuck in if I knew anything about map-making! 🙂
For the craggy mountain areas that I’ve compared, the OS opendata appears identical to the crag details found on the best OS 1:25k Explorer mapping. Having the OS crag details makes the OpenAndroMaps so much better for use in the mountains. For many classic mountain routes in the UK the OpenAndroMaps are now probably a better map to use than the OS maps. Many of the well-walked paths, particularly on the high ground in Scotland, are not marked on the OS maps, even in honeypot areas like Glencoe and Torridon. Those paths are often part of the OSM data. Take a look at Slioch. Beinn Alligin, Ben Eighe, Liatach, Aonach Eagach, CMD arete on Ben Nevis etc. The regularly used thoroughfares on the higher ground simply aren’t marked on the OS Explorer maps. Those paths are on the OpenAndroMaps. Great.
I saw a question earlier about OS Terrain 50 contours vs the Sonny generated contours. They don’t look a million miles apart but I have noticed some strange artefacts in the Sonny contours. I’ve no doubt the OS Terrain 50 contours will have been generated from more accurate data and will be consistently accurate. I’d prefer to see the OS contours on the British maps. WalkLakes.co.uk use the Terrain 50 contours on their excellent WayMaps which are a combination of OS and OSM data. You can compare the Terrain 50 WayMap directly with the OS 1:25k Explorer mapping. The very fine detail is missing from the Terrain 50 contours as you’d expect, but they are very good. Register for free and you can see two maps, side by side. See attached image of a popular Glencoe honeypot spot.
