[mkgmap-dev] one correction of default points style and a suggestion for lines

Fri Dec 3 17:45:27 GMT 2021

Hi Ticker.
So for the roundabout you mean something like a 2 line combination, is it?:

junction=roundabout & highway=service [0x0c road_class=0 road_speed=1 
resolution 24 continue]
junction=roundabout & highway=service [0x07 road_class=0 road_speed=1 
resolution 23]

For the emergency phone and other points, i leave it to you who have more 
experiance.
Around here, emergency phones are mostly present in remote areas where no 
other communication is present, so it does make sense to show on the map, but 
given your explenation i will keep it in my style only.

Regards
Karl
