Re: [mkgmap-dev] (Fixed by workround) Bizarre flooding in South Wales

As it is, it *seems* to realise that the coastline file is as I'd flagged it, but then reports that it can't read such a file. Confusing.

That is rather silly behavior indeed :).

P.S: I can now confirm that Bartosz's fix (specifying a separate coastline file) appears to have completely fixed my flooding issues.

I am quite convinced my analysis of the problem is correct. I know what is going wrong. And the only way to fix it that I can see is to use coastlines based on a larger extract that the one you are processing into a map. Hence, European coastlines when generating a map for the EU are not really a hack or a workaround. They are the correct solution. - Bartosz
