- building will be from ZL 14 and the importatnt ones from ZL13
- landuse=retail from ZL 13

But, my OP was concerned with why LoMap and OAM render differently.

OAM does a lot of preprocessing on cycle tracks and lanes to attempt to make sense of the various ways of mapping them. Lomaps does minimal preprocessing.

@karlchick
To be honest, I can't quite recall exactly what was unreliable. It's not the direction of drawing the way because that would make the one-way incorrect. The theme allows for "reverse one ways".
I think the "unreliability" was simply that there are quite a few different ways of mapping this situation and OAM maps can't pick then all up.
I do recall there was one particular junction in Cambridge with bike lanes and turning filter lanes that looked like a dogs dinner and left me unsatisfied with the result in Voluntary.
But also, l purposely keep the number of options to a minimum and thought that "drive on left/right" choice for just one particular scenario was too much.

@karlchick
Embedded within my code for Voluntary, there is an option for drive on the left or drive on the right for cycle lanes.
It seemed a good idea at the time but I left it as a hidden option (read the beginning of the theme XML file) as the mapping was not reliable enough to make it worthwhile. I decided in the end to treat the marking as symbolic, rather like the pylon markings on a power line don't indicate where the individual pylons actually are.
I also don't like the fact that the lack of radio buttons for either/or choices means you have to rely on the user to turn off one option and turn on another.
Cycle lane mapping is complex and has too many different ways of mapping the same thing to be able to achieve a truly satisfactory solution.

Can you give me a position, would also like to look. Just to be safe: you're aware there's tag transform documentation on the OAM homepage?

@karlchick
place=locality from z15 - changed
buildings - which buildings are important?
landuse=retail - does it have any effect for zl=10?  I mean - these areas are often quite small and the user cannot recognize them in zl=10

OK, it's changed...

I like the idea and I like the appearance. However the colours don't make sense for the Landranger style (foot=red, bike=green).
Also, I'm still seeing black lines under some footpath lines for all styles. I can't turn them off by unchecking any of the boxes.

With "Dynamic" I can get black and green dashes interfering but Explorer and Landranger are perfectly ok.

I really think this is a remarkable achievement!
Some points:
- I can't get the ROW highlighting to show whatever I do. I'm using Locus classic and both Lomaps and OAM.
- The legend didn't appear within Locus until I had opened it outside the app first, then it worked. Android 13 strangeness, I think.
- Landranger Power lines seem a tad over-heavy when zoomed in.
Otherwise, very good!!

karlchick, Thank you for all you've done working on this theme. I've used the previous version for ages and find it the best theme available so I'm very happy to see this latest version.
I have found what might be a problem, when viewing at zoom levels 14 & 15, one of the paths turns into a heavy black line as shown in the images.

@karlchick yes, 'lm_highway' is a copy of the original 'highway' tag. So every value of the 'highway' tag is available in 'lm_highway' tag. Of course, you need to take into account the set of tags of the tag mapping file https://github.com/asamm/lomaps-mapsforge/blob/main/various/tag-mapping-xml/tag-mapping-tourist.xml#L1328

The following tags are copied from the original way to "marked trail" way:
- highway (as lm_highway)
- sac_scale
- tunnel
- bridge
- layer
and ferry=route is mapped to custom lm_highway=ferry

That particular nature reserve is malformed in the mapping. It doesn't form a closed area and my theme specifically checks for that to avoid unpleasant artefacts.

@karlchick the updated England map is available in the Locus Store. (the map version remains the same - please delete the map and download it again)

@karlchick
thank you - problem was more complicated. All ways in relation were ignored in case that the relation has another child relation. And only members of such child relation were marked as bicycle route.
I'll inform you when map is fixed (re-generated)
