Even,
Did not get it all. You want a method that allows you to tell between a
map and aerial/satellite image?
Yes exactly
I believe the k-means algorithm would produce quite good results on maps

Are maps better candidates for image compression than natural images ?
Interesting idea ! For lossless compression methods such as deflate, yes maps
will likely have a better compression ratio.

This is the problem step:
gdalwarp -rcs -ts 8800 6600 -s_srs EPSG:32662 -t_srs EPSG:4326 temp.tif
target.tif
gdalinfo -mm -stats target.tif
is showing that the range of values in the image are dramatically
different on the two servers!
summary old:
Band 1 Block=8800x1
Perhaps differences in the hdf driver between the two versions could
explain differences in output.
Try converting netcdf file to gtiff with gdal_translate (using one gdal
version), then try gdalwarp from that common gtiff file.

I am trying to do a crazy What if...? climate model experiment that
involves changing the location of the poles. So, mind you, I am not merely
trying to change the coordinate display and use a rotated pole grid. I am
actually trying to locate the pole somewhere else (for instance, in
Australia),
