Hello-

I am looking for some examples on how to use "projections" with
Mapserver. I am by no means a GIS guru, nor do I fully understand
"projections", I just know that my maps that I am creating (
http://www.crh.noaa.gov/wwamaps/ ) are being compressed and have a
"squished" looked to them, and I was told I need to "project" my data
differently. So I'm hoping to find some pretty simple examples I can
look at and learn from.

I am looking to use "Ellipsoidal Mercator" as a projection, if that
helps any.

If I need to provide more data, please let me know and I can. I just
don't know where to start with this, so any help is greatly appreciated.

Thanks in advance!
