Group / Scale

[James Net]

Hello all,

I have a high res raster map of a fixed extent. I want to do the following, 
but don't know how: I want to group my high res raster with JPL bue marble 
so that when I zoom out I see the JPL blue marbe map, but when I zoom into 
my extent I render my high res raster map.

With my mapserver map file, I'm stuck here:

   LAYER
      NAME     "marble"
      TYPE     RASTER
      STATUS   ON
      GROUP    "earth"
      MAXSCALE ???
      MINSCALE ???
      CONNECTION     "http://wms.jpl.nasa.gov/wms.cgi?"
      CONNECTIONTYPE WMS
      METADATA
         "wms_srs"             "EPSG:4326"
         "wms_name"            "BMNG"
         "wms_server_version"  "1.1.1"
         "wms_format"          "image/jpeg"
      END
   END

        LAYER
                NAME    "my_high_res_map"
                DATA    "data/my_mosaic.tif"
                TYPE    RASTER
                STATUS  ON
                GROUP   "earth"
                TRANSPARENCY    ALPHA
                OFFSITE 0 0 0
                MAXSCALE        4000000.0
               MINSCALE        ??? #0.0
                METADATA
                        wms_title       "base_map"
                        wms_srs         "EPSG:4326"
                END
        END

Any help would be great, I've been at it all day without luck!


Many thanks,

James
