Thank you for your kind reply, Mr. Alpert & Mr. McNierney, but I am
still not be able to figure out what is wrong.. sorry.
Mr. Alpert, I am quite sure that I passed the layer="DOP04" just like
any other layers (shapefiles, POSTGIS data).. The one thing that I am
not sure is that I used "init=epsg:26971" projection but in fact all my
data are in feet, not meter. It didn't affect my other shapefiles &
POSTGIS data, but will it affect raster data..?
Mr. McNierney, my "DOP04.tif" file is huge, actually.. 357MB, dimensions
w=25000 x h=15000 in pixel. Could it be a problem..?

Thank you so much. Chieko

Post your EXTENT and PROJECTION information for you map file. Most of
the time when something just doesn't show up it's and EXTENT/PROJECTION
problem or you didn't pass layers=DOP04 in the URL

Subject: [UMN_MAPSERVER-USERS] Having trouble displaying GeoTIFF raster
data
I have an 8-bit greyscale aerial photo GeoTiff image (with coordinates
information in the header) that I want to add to my map, but I cannot
seem to get it to work. The strange thing is, I don't get any error
message when rendering the output PNG image - and still there is no
aerial photo. My map and the GeoTiff are in the same coordinate system
(init=epsg:26971) so I thought simply adding a layer to the .map file
would work, but it didn't. I think I am missing something very simple
but don't know what. Will anybody please advise me? Any input would be
appreciated.
My test site is: http://cmaene.lib.uic.edu/apress/campusmap11.php
I am using PHP/mapscript 4.6 (MapServer for Windows, MS4W, pre-compiled
.exe version) on Microsoft-IIS/5.1, and here is the version string from
MapServer & MapScript:
MapServer version 4.6.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER INPUT=JPEG INPUT=POSTGIS
INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE DEBUG=MSDEBUG PHP MapScript Version
($Revision: 1.235 $ $Date: 2005/06/14 16:03:35 $)
The layer info:
#####################################
# the output IMAGETYPE is PNG
# the input GeoTIFF is in the same SHAPEPATH
LAYER
NAME "DOP04"
TYPE RASTER
STATUS on
DATA "DOP4.tif"
PROJECTION
"init=epsg:26971"
END
END
#####################################
I tried:
- switchig layer status to "on" or "default"
- adding a world file (.tfw) to the GeoTiff
0.550000000000000040
0.0
0.0
-0.550000000000000040
1159375.2749999999
1900374.7250000003
- adding "PROCESSING" and/or "PROJECTION" classes to the layer in the
map file to make sure that the GeoTIFF file is read via GDAL.
- converting the GeoTiff to JPEG using Photoshop and then add a world
file (.jgw) - again, the airphoto didn't show-up, but no error message.
- converting the GeoTiff to PNG using tiff2png and PNG2, but the
conversion attempts failed (lack of memory?? original GeoTIFF is 350 MB,
or the header information wasn't read properly?)
