<DIV><FONT size=2 face=Arial>I have set up a MapServer WMS for several global
scale spatial data. The original crs for these data is WGS84 (EPSG:4326). I got
weird maps when I requested this WMS using projections like EPSG:54008 (World
Sinusoidal) and EPSG:54009 (World Mollweide). Those maps created by this WMS
looks like a mess in north pole and south pole areas, as shown in the attached
screenshots. You can also test this WMS by clicking the two links
below.</FONT></DIV>
