[mapserver-users] RE: Overriding MapServer Map File "DATA" parameter

[Lime, Steve D (DNR)]

You need to set a validation pattern to muck with the DATA attribute. You'd add something like this to your layer definition:

VALIDATION
  'data' '^terr_.*\.vrt$'
END

Subject: [mapserver-users] Overriding MapServer Map File "DATA" parameter

List,
I am trying to override  virtual raster (.vrt) file defined in mapfile with a different one from a list of vrt files. I am using Opnelayers and Mapserver 5.6.6 to create map. In Openlayers, I have tried:

var Terra250tif = new OpenLayers.Layer.MapServer( "Terra250m_bands1-4-3",
            "http://192.225.64.118/cgi-bin/mapserv?",
{
layers:"Terra250tif","map.layer[Terra250tif]":"DATA terr_ndvi.vrt",
map: '/usr/local/apache/htdocs/mapfiles/rrglobal_terra_250m_2011052jpg.map'
}, {singleTile:false});

The relevant part of the mapfile is:

LAYER
NAME "Terra250_367jpg"
    TYPE RASTER
    STATUS DEFAULT
    OFFSITE 0 0 0
  PROJECTION
    "init=epsg:4326"
  END
    DATA "terr_250m_2011052jpg.vrt"
      CLASS
          STYLE
            BACKGROUNDCOLOR 255 255 255
          END
      END
END


I looked at "mapserver.osgeo.org/cgi/controls.html....." but that did not helped. So, could anyone help with this.

Thanks,

Asad
