[mkgmap-dev] EU map too big?

Thu May 14 07:43:18 BST 2015

Hi again,

shapes turned out to be simple, with r3592 the overview map
file size is again smaller, esp. when the map contains
sea or forest polygons.
The ratio depends on the style, the 30% below were for the default
style which adds motorways.
For a map of Ireland, I see now 98KB with r3592 and 142KB with r3590,
both with "Openfietsmap full" style.

Hi Minko,

I've just noticed that the merge-lines option was ignored and disabled by default when 
the overview map was created. I've changed that with r3591.
The effect is great, the overview map size is reduced by > 30% .
I have  to look into the shape merging process, it does not yet work
with the overview map.
