[mkgmap-dev] Either mkgmap error or splitter error

Thu May 28 08:41:23 BST 2009

I know that you requested this before, but I see no good way to 
implement this and satisfy everyone's needs. Perhaps for Finland, 
Iceland and other island nations this might work, but what about 
countries with neighbors on each side and no straight borders? There 
would always be someone complaining about the tile edges.

So for now I've decided not to do any of those adjustments. What's the 
harm in having a section of another country on your GPS? The bit about 
code pages is interesting, but I would rather focus on internationally 
readable maps than localized maps (which can be easily generated by an 
OSM user from that country).

Perhaps this reasoning will change when polygon tiles are possible.
