Hello,
the brilliant osm coastline tool from Jochen Topf
(http://blog.jochentopf.com/2012-04-19-more-coastlines-stuff.html)
enables for creating nice ocean or landcover polygons from
Openstreetmap data. Well, this is where my mapserver problem
starts...
For illustration of the problem I just cre
with a recentish version of mapserver, try setting
PROCESSING "APPROXIMATION_SCALE=FULL"
on your ocean layer, to avoid feature simplification (it will slow
down the rendering if the resolution of your data is much greater than
the resolution of the requested map).

Hi,
Perhaps it is mostly an AGG issue because I think that Mapnik makes similar
artifacts too. See Corine landuse polygons here
http://www.openstreetmap.org/?lat=60.820709&lon=27.201925&zoom=
you can fiddle with gamma correction in mapserver trunk, c.f.
