Hi Ticker,

I don't see yet how floodblocker is related to MP processing?

Betreff: Re: [mkgmap-dev] Removal of floodblocker generate-sea option

I don't use precomp-sea, but I don't use floodblocker either, so the suggestion 
is fine by me. It may however be worth displaying a warning if a tile appears 
to be flooded.

Cheers,
Mike

Subject: [mkgmap-dev] Removal of floodblocker generate-sea option

Hi all

I think it is time that that the floodblocker logic is removed.

I doubt if anyone uses it.

The recommended way to have sea is to use --precomp-sea and
floodblocker is irrelevant to this.

Using the coastline data from the normal OSM input, the common sea
problems are in tiles that extend beyond the extracted region, where
coastline is incomplete (not reaching tile edges, or has gaps where
there are estuaries) and floodblocker is no use in this case.

This could be done as part of the "faster-mp" branch as it removes an
interface into MultiPolygonRelation, reducing the effort to restructure
this.
