[mapserver-users] Simple MrSid map file

[Brent Fraser]

Ken,

  Here's a minimal Map file (edited from the well-known Itasca demo data):

MAP
  NAME ITASCA
  STATUS ON

  IMAGETYPE PNG
  SIZE 600 600

# Projection - same as input data (UTM Zone 15, NAD83),
#              so no need to have MapServer re-project
  UNITS METERS
#        [minx] [miny]  [maxx] [maxy] in meters
  EXTENT 388107 5203120 500896 5310243

  #---------------------------------------------------------
  WEB
    IMAGEPATH "C:\Inetpub\wwwroot\tmp"
    IMAGEURL                    "\tmp"
  END

  #---------------------------------------------------------
  LAYER
    NAME drgs
    TYPE RASTER
    STATUS ON
    DATA "C:\Inetpub\wwwroot\workshop-5.0\data\drgncimq1942.tif"
  END

END # Map File

Not that I've tested it...

>>
>> 3. Check your DATA value in the map file's LAYER.  Is the path correct?
>> Is Mapserver able to access the file?
