[mkgmap-dev] Flooding in Southern Scotland

Fri Dec 9 19:59:14 GMT 2011

This sounds like today's weather reports, but it isn't.

For some time I have been downloading the England, Scotland and Wales 
files from Geofabrik, and compiling these with mkgmap.

Today, I have encountered a problem with sea flooding in SW Scotland/NW 
England. Compiling Scotland alone works fine. Compiling England has a 
small area of flooding around Carlisle. Compiling both together produces 
a very large area of flooding in both England and Scotland.

Screenshots from mapsource for these last two are at

and

respectively.

My command line includes
--generate-sea=multipolygon,extend-sea-sectors,close-gaps=1000,floodblocker

Has anyone else encountered this? I would appreciate any ideas as to 
where to look for the problem.

Many thanks,

Roger
