[mkgmap-dev] Small holes in boundary coverage

Mon Mar 26 22:11:02 BST 2012

Hi Gerd,

thanks for the patch. I have commited it although I still see the 
problem. I am not sure if the holes are at the same place but there are 
some of them which I cannot explain with wrong boundary data.

Can you please recheck that?

Thanks!
WanMil
