Venkat,
Check your IMAGEPATH and IMAGEURL... IMAGEPATH should point to the
local path (which is correct in your example, except it needs the ending
slash "/"). IMAGEURL is the path relative to the web root--this is
assuming you've defined an Alias (virtual directory) for your temp
directory. Since you seem to be using IIS, I'll assume your IMAGEURL is
actually the path after "C:\Inetpub\wwwroot"... so, your IMAGEURL is
probably "/RoulacGIS/MapFile/tmp/"
So, IMAGEPATH is the local path (local to your server) and IMAGEURL is
the "web path" (relative to the web server's root URL).
You can check whether the reference works or not outside of your C#
app--just run a MapServer CGI request like this:
http://localhost/cgi-bin/mapserv.exe?map=/Inetpub/wwwroot/RoulacGIS/MapFile/tmp/yourmapfile.map&mode=reference
This request should return your reference image. It will not fix any C#
related problems you may have.
I recommend that you familiarize yourself with the MapServer map file
reference: http://mapserver.gis.umn.edu/docs/reference/mapfile
You might also want to check Jeff McKenna's MapServer User's Manual
(which is in draft form right now):
