[talk-au] re Coastline rendering in Garmins Mapsource
Seems Openmtbmap has recently got 'sea polygons' organized. :) Here is a Mapsource Noosa view. It's not 100% for the entire coastline, but it's pretty damn good. http://img687.imageshack.us/img687/6421/noosamtb.jpg Regards John k ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

Re: [talk-au] re Coastline rendering in Garmins Mapsource
I sorted the maps today - stoopid downloads not working, and I obviously can't write a decent batch script to save my life Would have fixed it earlier, but not at work to do so - Australia Day for me generally results in a hangover, as it's also my birthday Matt John Kitchener wrote: Matt wrote: Coastlines (and the inverse islands issues) have been ongoing for ages for the Mkgmap produced Garmin files. There's a --generate-sea switch for Mkgmap that sometimes works fine, other times, not so good. It's hit and miss enough that I've never enabled it for the maps I generate. Problem seems to come from a few different things - non-closed coastline polygons, coastline direction changes, points where rivers join sea/coastline etc. There's a lot of chat on the mkg-map dev list over the last 6 months or so regarding this. Matt --- Thanks Matt. Without 'sea polygons' it'll remain a complete mess for Garmin displays. We need OSM to work in the 'real world' to accelerate uptake. Hopefully the --generate-sea- switch comes good in Mkgmap. Until then . John k PS The OsmAustralia downloads appear stuck at the 26/1 at 22b.

But I've tried adding: --generate-sea=polygons,no-sea-sectors,close-gaps=2000 to the mkgmap command, and I've added: natural=sea [0x32 resolution 10] natural=land [0x27 resolution 10] as the first two lines of the mkgmap polygons style file. There's no improvement in the rendering of the ocean. As I'm making a Garmin map which includes New Zealand, I had a look there. The same problem exists - the ocean looks like land.

Coastlines (and the inverse islands issues) have been onging for ages for the mkgmap produced garmin files.

How is the garmin util converting from osm2garmin format? There is shape files which are error checkef before mapnik renders tiles...
