But I see it only when displaying small islands on a see. Like for example PrÃncipe Island or Ascension Island. Could it be, that processing sea level or voids around island could cause similar effects like polygon border? All my maps are currently compiled with patched mkgmap, I can't tell if original mkgmap shows this effect too. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
