Help with displaying a single RASTER image

[Ethan Alpert]

Make sure the units/projection of your geotiff are the same as your
EXTENT.

Gdalinfo is your friend....

Subject: [UMN_MAPSERVER-USERS] Help with displaying a single RASTER
image


I am reviewing the tutorial and re-learning the MapServer by looking
over work that I had done previously on another computer and converting
examples that I had done with my own data (and that previously worked)
to the new paths on this computer. Now I am finding that I cannot get
the server to display a single GeoTIFF image under some vector data. I
can see the vector data but the raster image won't draw for some reason.
I hope that someone out there has some suggestion as to why the raster
isn't appearing. I have checked my path to the raster data and it is
correct. I have tried settings with processing the COLOR_MATCH_THRESHOLD
and it didn't work. I even tried turning off INTERLACE in the map image
and it didn't work.

The strange thing is that when I jump ahead to an example that I had
done with image tiles, this works and displays the raster tiles. But I
can't seem to get it to work with a single image. I also can't get the
raster in the standard tutorial35 to display.

Does anyone out there have an answer to my problem?

My MapServer configuration is:

C:\Apache\htdocs\MapserverTutorial>..\CGI-BIN\MAPSERV.EXE -v MapServer
version 4.2.3 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF
OUTPUT=SWF SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER
SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT
INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

My map file is:

END # end of map file

and the line in my HTML file that runs the MapServer is:

thanks in advance for your help.
