raster projector

[John Smith]

guys,
trying to put a geotiff in- works but not right. here's what's happening:

i download the geotiff from national atlas. when i give no proj info under
LAYER it shows up but not where it should (nwis). so i copy MAP proj to
LAYER proj hoping for some on-the-fly magic- again it shows up but nwis.

well i go over to
proj_list<http://www.remotesensing.org/geotiff/proj_list/>and look up
the epsg (EPSG?) code (9820) from metadata but it throws the
"msProcessProjection(): Projection library error. no options found in 'init'
file" error. then i try all epsg codes given by gdalinfo ;) but same error.
although when i try the MAP epsg code (4326) it shows up but nwis.

so what's wrong here? think proj.exe geod.exe cs2cs.exe libgeotiff listgeo'd
help? now i don't think wld is needed because it's included with the geotiff
but i've tried with wld and no luck. i just hope i don't have to rectify in
arcmap. btw IMAGETYPE=png24 in case that matters.
