Hi Ivan,

gdalinfo is showing subdataset list also, the previous mail contains
gdalinfo of one of subdataset.  I have used gdal_translate to convert
the following in GeoTIFF image, however i don't have idea about how to
create layer for the given hdf subdataset.

the below is the gdalinfo showing subdataset list:

Driver: HDF5Image/HDF5 Dataset
Files: none associated
Size is 1440, 720
Coordinate System is:
GEOGCS["WGS 84",
    DATUM["WGS_1984",
        SPHEROID["WGS 84",6378137,298.257223563,
            AUTHORITY["EPSG","7030"]],
        TOWGS84[0,0,0,0,0,0,0],
        AUTHORITY["EPSG","6326"]],
    PRIMEM["Greenwich",0,
        AUTHORITY["EPSG","8901"]],
    UNIT["degree",0.0174532925199433,
