[mapserver-users] EXTENT

Subrahmanyam -
 
I have set up a very simple sample that demonstrates what you're trying to do.  If you take a look at this URL:
 
http://www.geozone.com/cgi-bin/mapserv.exe?mode=map <http://www.geozone.com/cgi-bin/mapserv.exe?mode=map&map=\MapServer\Subrahmanyam\utm-wgs84.map> &map=\MapServer\Subrahmanyam\utm-wgs84.map
 
you will see the quad you're working on (O33085H5.TIF) displayed at 400x500 pixels reprojected into lat/lon WGS84 as you desire.
 
The source raster data is just the standard USGS NAD27 GeoTIFF file.  The complete MAP file referenced in the URL is:
 
SIZE 400 500
EXTENT -85.625000 33.875000 -85.500000 34.000000
 
PROJECTION
    "init=epsg:4326"
END
 
LAYER
  TYPE RASTER
  STATUS DEFAULT
  DATA O33085H5.TIF 
  PROJECTION
    "init=epsg:26716"
  END
END
 
END

Let me (and the list) know if you have more questions after you take a look.

hai,
       i has the TIFF image,which is in EPSG:26716 projection and its bounding co-ordinates are as follows:
  WEST BOUNDING COORDINATE:  -85.625000
  EAST BOUNDING COORDINATE:  -85.500000  
  NORTH BOUNDING COORDINATE:  34.000000 
  SOUTH BOUNDING COORDINATE:  33.875000 
      i wnat to reproject this image in EPSG:4326 projection.
         does anybody knows ,how to calculate the EXTENT values for this image based on above information?
           if some body knows,please mail me, that would be a great help
 
thanks
