[mkgmap-dev] Compilation fails building France map

Sun May 24 17:09:38 BST 2020

Hi Steph,

as I expected. The data looks completely wrong. My guess: The bano data contains ids in the same range as the real OSM data.
In your sample file I see a huge amount of long motorways, and those will make it into the overview map. Anyway, all map tiles will also contain this error.

Zipped files…
http://files.mkgmap.org.uk/download/471/pbf-with-bano.zip

Including the last .osm.pbf produced.
