[mkgmap-dev] display of place names on lower zoom levels

Mon Jun 27 21:41:10 BST 2011

Also note, that labels have nothing to do with resolution. They depend 
much more on the 0x type. Also there is a difference in importance of 
labels of POI/POLYGON/POLYLINES.

If a place is shown but no label, then lowering the resolution won't 
change (but instead create a mess in the lower resolutions).
The only improvement would be to include population>?? to places 
(particulary cities & towns) for finer separation. However this would 
then still cause problems if looking at i.e. Benelux/Nordrein-Westfalen 
vs less populated regions.
If you want a map for Alaska you could simply lower resolution for 
nearly everything by 1-2 levels. However that should not be default 
(default should be based on rather heavily populated regions, as those 
regions have most potential people using the maps...).
