Hi, I created a map of a cutout of the europe geofabrik extract including generate sea option. All is OK, but one tile is white instead of blue because it's completely in the sea and contains no coastline. How to detect such tiles? I think this is easy: It contains no or very few data (only some ferry lines). An option for detecting such sea tiles and filling with a sea polygon would be nice. Christian

I'm sure there is an sub-option to --generate-sea that created sea tiles like this. I think it might be extend-sea-sectors. You might have to use the polygons version of generate-sea for it to work though (at least, I don't use mp version of generate-sea so I don't know either way). -- Charlie

I'm using generate-sea=extend-sea-sectors. Chris

Maybe it's no-sea-sectors then...? -- Charlie

I find that --generate-sea:multipolygon,extend-sea-sectors,close-gaps=6000 always works for me or --generate-sea=polygons,extend-sea-sectors,close-gaps=6000 Most times works. Just remember to include in the polygons file for the style natural=sea [0x32 resolution 12] natural=land [0x27 resolution 12] Markus_g -----Original Message----- From: mkgmap-dev-bounces@lists.mkgmap.org.uk [mailto:mkgmap-dev-bounces@lists.mkgmap.org.uk] On Behalf Of charlie@cferrero.net Sent: Tuesday, 9 November 2010 7:40 PM To: mkgmap-dev@lists.mkgmap.org.uk Subject: Re: [mkgmap-dev] Sea Detection Chris66 (chris66nrw@gmx.de) wrote:
