Greg -
You create a map file with one LAYER for each resolution, all members of
one GROUP with the same name, and each layer having a MINSCALE and
MAXSCALE setting so only one layer of the group at a time is displayed.
If you're not familiar with those capitalized keywords you should do
some reading on them - you can also find other discussions in the
archives on this topic by searching on those keywords.

Subject: [UMN_MAPSERVER-USERS] image pyramid viewing software
For 100 large metropolitan areas, I have created separate reduced-
resolution GeoTIFF images at 120, 60, 30, 15, 7.5, 3.75, and 1.875
meters resolution. I want to be able to zoom in, zoom out, and pan
through this imagery, and have MapServer display's at any given time
be from the GeoTIFF that is most appropriate, based on the current
zoom. How can this be done with MapServer?
Greg
