Hi Gerd
So, what I am looking for is a tool that helps to find
areas which are heavily overlapped, something like
a heatmap.
When displayed it looks like this:
http://files.mkgmap.org.uk/download/223/Selection_040.png
I need to add a couple of getters and a fix to mkgmap (attached)
then I will check it all into display.
