Ryan,
Do you have projection blocks for the MAP and LAYER. I don't see one in
the layer.
David.

My problem is that no matter what I have my SRS numbers set to my data
will always be displayed the same what. What could I be missing that
would cause MapServer's re-projection capabilities not to work.
I have several tiled .tiff images that I georeference by lat/long values
using: gdal_translate -a_ullr 180 0 210 -30 thm_dir_N-30_180.png
thm_dir_N-30_180.tiff
I am then displaying them in MapServer using:
LAYER
NAME "themis"
STATUS ON
TILEINDEX "thm_dir.shp"
TILEITEM "location"
TYPE RASTER
DUMP TRUE
METADATA
wcs_name "THEMIS_Data"
wcs_description "THEMIS dataset"
wcs_label "THEMIS dataset"
ows_srs "EPSG:4326"
ows_extent "0 -90 360 90"
wcs_resolution "150 150"
wcs_size "2700 3197"
wcs_formats "GEOTIFF"
END
END
Here is what gdalinfo reports, but isn't it MapServer that does all the
re-projection? So that fact that the Coordinate System here is blank is
ok right?
