[mapserver-users] Use Ground Control Points from GeoTIFF

[Jesper Kempe]

Hi

This is the mapfile:

MAP
    NAME "map"
    WEB
        METADATA
            "wms_title"            "WMS mapserver"
            "wms_srs"              "EPSG:4326 EPSG:3021 EPSG:9999 EPSG:3006
EPSG:900913"
            "wms_extent"           "1225000 6130000 1910000 7675000"
            "wms_enable_request"   "*"
            "wfs_enable_request"   "*"
        END
    END

    PROJECTION
        "init=epsg:4326"
    END

    EXTENT -180 -90 180 90

    LAYER
      NAME "sat"
      DATA "sat.tif"
      TYPE RASTER
      STATUS ON

      METADATA
                "wms_title" "sat"
      END

      PROJECTION
        "init=epsg:4326"
      END
      EXTENT 17.0473154408269387 62.1606759790530177 27.5792082876237146
66.7744046276809797

    END

END

I have also tried both without PROJECTION in LAYER and with
PROJECTION
     AUTO
END

None of them works.

EXTENT in the mapfile is taken from Qgis metadata of the layer.


Thanks
Jesper
