Hallo Gerd


You just solved a long time wish of getting country borders more nice at low 
zoom:

Left with overview 8:12  and right with lowest  8:13 (which is much nicer !)





Basecamp zoomlevel 300km

Onderwerp: [mkgmap-dev] splitter default resolution 13 and overview map from 
default style



Hi all,



I am not sure but I think it is a bad idea to have overview-levels = 4:17, 
5:16, 6:15, 7:14, 8:12 in the default style.

The lowest resolution is 12 while splitter uses the default 13 for its 
resolution. This also means that tiles from splitter are aligned to a 
resolution of 13. The lowest level in the overview map is therefore sometimes 
much more distorted at tile boundaries than the next higher. I think it should 
be changed to overview-levels = 4:17, 5:16, 6:15, 7:14, 8:13



I've never thought about this relationship between splitter and the overview 
map. Just wondered why my test data looks so ugly at resolution 12.

An alternative would be to remove the lowest level completely.

Maybe mkgmap should print a warning when tiles are not aligned for the lowest 
resolution used in the map?



Any thoughts?



Gerd
