[mkgmap-dev] Mkgmap dropping data

Wed Aug 3 22:40:40 BST 2011

Sorry, I thought MapSource usage is common on this list. The red areas are
where the map was completely rendered and you can mark them for upload. The
grey and yelllow areas are rendered only on the lowest resolution, so they
cannot marked for upload. The rendering process is broken, but mkgmap
doesn't give any hint why.
NSIS is an alternative to MapSetToolkit? I'm satisfied with MapSetToolkit, I
don't think it has anything to do with the problem. Do you have to use
cgpsMapper with NSIS?
