[mkgmap-dev] Bizarre flooding in South Wales

You can try the following:

Download the European coastline file from [1] with the same time stamp 
as your input pbf and pass it to mkgmap via the --coastlinefile option. 
If this fixes the flooding, you are suffering from the same problem that 
I keep running into - the coastline fails to reach some of the tile 
boundaries.
