[Mapserver-users] Help Request

[Kieran J. Ames]

Ed,
Thanks for trying to help me today. I appreciate your time.
>From what I can gather, my street data (from ArcView Streetmaps) ARE
"NAD27 Aware". All research I have done thus far indicates that I can't
put these streets on the same map as these polygons and have them line
up.

I found that if I unproject the wetlands NAD27 data and wetlands NAD83
data of the same spatial area, (forget about including my street
information), they will not even line up with each other. However, the
unprojected NAD27 data DO line up with my streets. No wonder I couldn't
get the NAD83 polygons to line up!

I find it interesting, however, that mapserver doesn't know how to make
these layers play nicely together... (or put better, that I don't know
how to tell mapserver to make them play nicely together.)

I'm cc'ing the list with this so as to document the apparent 'dis-parity'
in some data sources. I'm sure there are several beginners (like myself)
that don't want to go through this time-intensive exercise.

Again... Thanks for your help.
Kieran
