[Mapserver-users] Newbie Question about rasters

[Ed McNierney]

Paul -

JPEG is a very poor format type to use for geospatial data, mainly due
to performance issues (you need to read and decode the entire image just
to get the value of one pixel).  It seems likely that MapServer is not
reading georeference information for your JPEG, while ArcGIS is.

What do you get when you run "mapserv -v" from the command line?

What is the filename of the georeference "world" file?  It will be
raster/ak.something

Subject: [Mapserver-users] Newbie Question about rasters

I've got a working installation of Mapserver w/ some test maps @
209.165.152.94.  Please feel free to drop by and check them out.  I'd
like to add a raster image layer to my maps.  I can't seem to get the
raster working w/ Mapserver.  I am using the same raster image in ArcGIS
and it works fine.  

I've tried several different things to try and make it work.  Please
give me any hints, clues or advice that you think is relative.  No help
will be turned away. :-)

Here is my map file:

MAP
  NAME map6
  IMAGETYPE PNG24
  EXTENT -903026 648632 1888140 1849511

    TEMPLATE  'map6.html'
    IMAGEPATH 'c:/program files/apache group/apache2/htdocs/tmp/'
    IMAGEURL '/tmp/'
#    LOG 'c:\mapserver.log'
  END
