Projection Issues

[Ed McNierney]

Bill -

You have no CLASS definition to describe the rendering style to be used
for your "Pinellas Roads" layer.  Add one, similar to the way you did
for the county outline layer - obviously, there's no OUTLINECOLOR
needed, and make sure you choose a color that's different than the
county polygon fill color!

Ed,
I took your advice and and replaced the projections with the espg codes.

I also simplified the map file to just have two layers: both shapefile,
not PostGIS.  However, I am still having the same problem: I only see
the county data when I put both in the file.

I've included the reduced map file below, and I've sent a copy of the
data to Paul to see if he can help.  Is there a standard way to
distribute layer files for review on this board?  Or should I post a URL
or the like?

Thanks for your time,
Bill
