Hi.  I have been playing around with mapserver and have been fairly
successful getting some thematic maps of our proince (B.C.) up and working
(sort of).  The difficulty I am having (other than difficulties associated
with not really knowing what I am doing) is :

when I use the proper extents with units=meters in the mapfile the resulting
map is "zoomed in" and shows only a small area of my map.  When I change the
units to inches everthing appears as I would expect it should but the
scalebar is way out.    The other associated problem is that I cant get the
reference map I have created to indicate my position on the main map.  I
have included a portion of my mapfile just in case it helps clarify my
problems

Any advice would be much appreciated.

THanks.
