[udig-devel] Class IGeoResourceInfo

[iomeneandrei]

Hi all,
we are using IGeoResourceInfo class to get the CRS of a layer.
We are using this kind of code:
public String getCRS(ILayer l){
        String s_crs="";
        IGeoResource resource = l.getGeoResource();
        try {
            IGeoResourceInfo info = resource.getInfo( new
NullProgressMonitor() );
            System.out.println("Info.getCRS:"+info.toString());
            CoordinateReferenceSystem crs=info.getCRS();
            s_crs = crs.toString();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return s_crs;
    }

If I print the CRS inside eclipse I have:

PROJCS["ED50 / UTM zone 33N",
  GEOGCS["ED50",
    DATUM["D_European_1950",
      SPHEROID["International_1924", 6378388.0, 297.0]],
    PRIMEM["Greenwich", 0.0],
    UNIT["degree", 0.017453292519943295],
    AXIS["Lon", EAST],
    AXIS["Lat", NORTH]],
  PROJECTION["Transverse_Mercator"],
  PARAMETER["central_meridian", 15.0],
  PARAMETER["latitude_of_origin", 0.0],
  PARAMETER["scale_factor", 0.9996],
  PARAMETER["false_easting", 500000.0],
  PARAMETER["false_northing", 0.0],
  UNIT["m", 1.0],
  AXIS["x", EAST],
  AXIS["y", NORTH]]

If I make in udig right click on this layer, and select Properties I have:

PROJCS["ED50 / UTM zone 33N", 
  GEOGCS["ED50", 
    DATUM["European_Datum_1950", 
      SPHEROID["International 1924", 6378388.0, 297.0,
AUTHORITY["EPSG","7022"]], 
      AUTHORITY["EPSG","6230"]], 
    PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]], 
    UNIT["degree", 0.017453292519943295], 
    AXIS["Lon", EAST], 
    AXIS["Lat", NORTH], 
    AUTHORITY["EPSG","4230"]], 
  PROJECTION["Transverse_Mercator"], 
  PARAMETER["central_meridian", 15.0], 
  PARAMETER["latitude_of_origin", 0.0], 
  PARAMETER["scale_factor", 0.9996], 
  PARAMETER["false_easting", 500000.0], 
  PARAMETER["false_northing", 0.0], 
  UNIT["m", 1.0], 
  AXIS["x", EAST], 
  AXIS["y", NORTH], 
  AUTHORITY["EPSG","23033"]]

It seems the some, but there is a difference is in the last record, in which
I can read the EPSG code.
Is it normal that these infos are different? If yes how can I read inside
eclipse the some info I can read in UDig?

I'm attaching the shapefile I have used to make this test.

Thank you,

Andrea
