[Mapserver-users] ArcMap and Geo-referenced TIFF file problem

[P Wilkerson]

I am nearing a critical deadline and I am really stumped and need help.

I cannot generate a georeferenced  TIFF using ArcMap that works within
Mapserver  The resolution is either too low or only a section of the map is
exported.

Help!

BACKGROUND INFORMATION

The group I am working with is trying to get a geo-referenced TIFF image
file exported from ArcMap so it can be used by Mapserver.   The problem is
that we can export a low-resolution map that is a working geo-referenced
TIFF but when we go to export the same map at, say, 300 dpi one of two
things happen:

    1) We only get an output of a part of the map that we can see on our
monitor screen rather than the whole map.   The resulting map also has its
colors changed to some unexpected colors, or...

    2) We get a high-resolution TIFF file that has lost its geo-referencing.

-----------------

    I tried the Geotiffe utility without success to set the values for the
high-resolution, non-georeferenced TIFF (scenario #2 above).

Below is a copy of a portion of my map file.   The boston1844 layer works
fine.  I cannot generate a georef TIFF that works for the  a1874 layer.
