What did you use for resolution 24? Maybe this is needed too? I use this without problems: place=city & mkgmap:area2poi!=true & capital=yes [0x0400 resolution 16] place=city & mkgmap:area2poi!=true & population>=200000 [0x0600 resolution 16-16 continue] place=city & mkgmap:area2poi!=true & population<200000 [0x0b00 resolution 16-16 continue] place=city & mkgmap:area2poi!=true & population>=200000 [0x0400 resolution 18-18 continue] place=city & mkgmap:area2poi!=true & population<200000 [0x0600 resolution 18-18 continue] place=city & mkgmap:area2poi!=true [0x0400 resolution 20] ---------- Chris66 wrote: Hi, when I changed my point file to: place=city [0x0400 resolution 22-16] place=town [0x0800 resolution 22-18] the map was corrupt (blank tiles in BaseCamp and other effects). So, is it not allowed to have a Resolution Range for POIs or is this a known bug ?
