Hi Gerd,

No, that's a mistake on my part. It looks like abandoned:highway=* is for the old highway value (e.g. abandoned:highway=classified) and if the highway tag is also present, it's for the current highway value (e.g. abandoned:highway=path). Ways with abandoned:highway but without highway should be ignored. I've updated the patch. Let me know if I didn't express that correctly.

Thanks, Ben

Hi Ben,


I think it is okay, but I don't yet see a need to handle abandoned:highway.

I find > 2100 ways that with abandoned:highway=* and highway=*.

Do you think these are not usable highways ?

Betreff: [mkgmap-dev] [patch] hide abandoned highways in default style
 
Hi Gerd,

Here's a patch to hide abandoned highways in the default style. Abandoned highways have some evidence of their former existence but are no longer used. I made a separate rule for this change to highlight that abandoned highways could be useful in topographical maps.

https://wiki.openstreetmap.org/wiki/Key:abandoned:

The rule also matches highway=abandoned. While not an official OSM rule, it is being used in the US an Europe:

https://taginfo.openstreetmap.org/tags/highway=abandoned#map

I also found a German wiki page for it but not a page in English:

https://wiki.openstreetmap.org/wiki/DE:Tag:highway%3Dabandoned

Let me know what you think.

Thanks, Ben
