[Gdal-dev] Geotiff format interpretation

[mattia]

Hey all, with some external tool using GDAL I managed to convert an HDF file
into a Geotiff.

If I now gdalinfo the file, I get the following output:

rasdaman at mattia-desktop:/opt/rasdaman/local$ gdalinfo -nomd Area1.tif
Driver: GTiff/GeoTIFF
Size is 7103, 3947
Coordinate System is:
PROJCS["HDFLook: LINEAR",
    GEOGCS["unnamed",
        DATUM["unknown",
            SPHEROID["unnamed",6370997,0]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433]],
    PROJECTION["Equirectangular"],
    PARAMETER["latitude_of_origin",0],
    PARAMETER["central_meridian",0],
    PARAMETER["false_easting",0],
    PARAMETER["false_northing",0],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]]]
Origin = (8912408.472916,7090227.412053)
Pixel Size = (694.49452741,-1000.15538912)
Corner Coordinates:
Upper Left  ( 8912408.473, 7090227.412) ( 80d 9'4.51"E, 63d45'50.32"N)
Lower Left  ( 8912408.473, 3142614.091) ( 80d 9'4.51"E, 28d15'43.99"N)
Upper Right (13845403.101, 7090227.412) (124d30'53.14"E, 63d45'50.32"N)
Lower Right (13845403.101, 3142614.091) (124d30'53.14"E, 28d15'43.99"N)
Center      (11378905.787, 5116420.752) (102d19'58.82"E, 46d 0'47.16"N)
Band 1 Block=7103x20 Type=Byte, ColorInterp=Red
Band 2 Block=7103x20 Type=Byte, ColorInterp=Green
Band 3 Block=7103x20 Type=Byte, ColorInterp=Blue


Now, I dont know what the EPSG 9001 system is and I cannot manage to google
it successfully..

I need to convert the given corner coordinates into WGS-84 easting northin
decimals..

I mainly need to define a bounding box using the lower left and upper right
corners..

Can anyone point me out on how I can do this?? Or what is the EPSG 9001
code?? Are those decimal values the ones in EPSG 9001??
What about the other notation (80d 9'4.51"E, 63d45'50.32" N)? What is it
indicating? is it still the EPSG 9001 representation? Or is it already the
WGS84 one?

Thanks in advance

Mattia
