[mkgmap-dev] Provincial capitals

Mon Sep 30 17:09:06 BST 2013

In case someone else is interested in the solution:
in the relations file, I added:

boundary=administrative & admin_level=* {
     apply role=admin_centre { set is_province_capital='${admin_level}'; }
}

And then in the points file:
...
place=city & population > 199999 & cityxx!=yes {set cityxx=yes} [0x0500 
level 4 continue with_actions ]
place=* & is_province_capital<5 & cityxx!=yes {set cityxx=yes} [0x0500 
level 4 continue with_actions ]
place=city & population >  99999 & cityxx!=yes {set cityxx=yes} [0x0600 
level 3 continue with_actions ]
place=* & is_province_capital<6 & cityxx!=yes {set cityxx=yes} [0x0600 
level 3 continue with_actions ]
place=city & population >  49999 & cityxx!=yes {set cityxx=yes} [0x0700 
level 3 continue with_actions ]
place=* & is_province_capital=* & cityxx!=yes {set cityxx=yes} [0x0700 
level 4 continue with_actions ]
place=city & population >   9999 & cityxx!=yes {set cityxx=yes} [0x0800 
level 3 continue with_actions ]
...
