[Mapserver-users] I'm getting a little frustrated...

[Ryan, Adam]

As a follow-up...ArcMap will reproject on the fly without you even knowing
it.  You can turn that feature off so the data frame will display layers in
their native projection.

Paul -

ArcMap will read .prj files for each layer (ESRI forgot to include
projection definitions in their earlier file formats) for determining what
projection they're in.  You need to have that information in the PROJECTION
block *inside* each LAYER block in your map file.

Know your data before trying to make it work in MapServer.  Your shapefiles
are likely to be in decimal degrees, but they might not be. ArcMap will
reproject layers into the projection of the current data view, and MapServer
will do the same.

Eureka!!!  Success at last!! WOOT!!! 

Ok, using the LISTGEO tool, I was able to find the correct extents to MY
(not the tutorial's) tif image.  I plugged those in on a test map and can
now see a working raster image in mapserver.  Now I have proff that it works
on my system in my environment.  THANK YOU ED!!!

Now, how do I display my raster and my shape files together on the same
page?  When I look at the extents, they don't overlap. However, when I add
them as two layers in ArcMap they mesh perfectly.  I do have a .wld
file for the tif.  Do I need to create/adjust my projections?    All the
files are NAD_27.  Again, this is a learning process for me, so I appreciate
all the help that everyone is giving me.

Here is the new .map file that I'm working with:
