We have a similar issue in Bangaldesh http://tile.openstreetmap.nl/coastlines.html?zoom=8&lat=23.43505&lon=89.95194&layers=B00T
Any ways to restore the square missing?

I generated a replacement shapefile for zoom 7-9[1] and rendered these tiles again. I'm tempted to use this shapefile for z6 or even z5 soon. Jon [1] Turns out this is quite easy to do with postgis: $ shp2pgsql -s 900913 -I -g way processed_p shoreline_a | psql -q gis ... $ pgsql2shp -f shoreline_300 gis "select simplify(way,300) as the_geom, gid as id from shoreline_a where area(simplify(way,300)) > 0" _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk François de Ryckel _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
