[mkgmap-dev] Disconnected map sections, types in TYP-files.

Fri Oct 9 14:41:35 BST 2020

Hi Karl,

okay, looked at 217.bmp. It doesn't seem to be related to tile boundaries. I think someone else reported similar problems, only visible on the device.
I've never seen them on my Oregon.
Do the gaps disappear when you zoom in or out?

Gerd
