[Mapserver-users] I'm getting a little frustrated...

[Paul VanDyke]

Thanks Ed for getting back so quickly.  I belive in the open-source
movement because people like you make it work!

Here is my map file that I'm using; it's an adaptation of the example
1-5 in the tutorial and uses that tiff file.

MAP
   NAME example
   IMAGETYPE PNG
   EXTENT 201621.496941 -294488.285333 1425518.020722 498254.511514
   SIZE 400 300
   SHAPEPATH "c:/program files/apache group/apache2/htdocs/data"
   DEBUG ON

WEB
   TEMPLATE 'example.html'
   IMAGEPATH '/data/tmp/'
   IMAGEURL '/tmp/'
   LOG 'C:\mapserver.log'
END


LAYER # MODIS raster layer begins here
  NAME         modis
  DATA         "raster/mod09a12003161_ugl_ll_8bit.tif"
  STATUS       DEFAULT
  TYPE         RASTER
  PROCESSING   "BANDS=1,2,3"
  OFFSITE      71 74 65

  PROJECTION
    "init=epsg:4326"
  END
END # MODIS raster layer ends here

# End of LAYER DEFINITIONS -------------------------------

END # end of map file


As I said, I'm a newbie to GIS so the projection stuff is foreign to me.
I figured that using the example file would be a safe bet.  Please
comment on what you see.

Thanks,

Paul

Paul -

There's nothing wrong with raster support on Windows - it works just
fine.  Posting your MAP file would help, too.  Are you sure the raster
layer is enabled (STATUS DEFAULT) in your map file?

The biggest problem people have with raster data is that it is typically
projected, while much vector data is not.  That means you're mixing data
with two different coordinate systems in the same map.  That's perfectly
OK and MapServer can handle it just fine, but you need to accurately
describe the projection of each of your input data sets AND the desired
output projection so MapServer can figure out what to do.
