Re: Worldwide routable Garmin maps: URL REMOVED

Since this tile is completely land covered I suspect there is wrong data in OSM: (a broken) natural=coastline.
The geofabrik tool for inspecting the coast line only is valid for the EU so I think you have to search for this yourself.

Lambertus, maybe add floodblocker in the scripts next time: --generate-sea=multipolygon,extend-sea-sectors,close-gaps=6000,floodblocker
