[Geotools-gt2-users] ArcGridReader

[Pablo V. <p4v...@ya...>]

Hi all.
   
  Why I can not use this code with geo-tools 2.3.0.?
   
          File file = new File("c:/pablo/java/spearfish_dem.asc.gz");
        ArcGridReader agr = new ArcGridReader(file);
        GridCoverage2D gc2 = (GridCoverage2D)agr.read(null);
   
  I got the next message:
   
  12-feb-2007 11:14:44 org.geotools.gce.arcgrid.ArcGridReader getCoordinateReferenceSystem
INFO: crs not found proceeding with EPSG:4326

  Thanks a lot.
   
  Pablo.
