[mkgmap-dev] new branch NOD127

Sun Mar 9 08:38:17 GMT 2014

Hi Thorsten,

Steve saw similar problems regarding tile boundaries.
He used an older version of MapSource (6.10.?)
and maybe tiles that were not split properly.
His problems were gone after updating to MapSource 6.16.3
and using a new split.
