[gdal-dev] Using gdalwarp with HDF files- problem reading proejction

[António Rocha]

Greetings

I have a dataset (in HDF) and I need to convert its projection. When I 
do gdalinfo I get this information:
Coordinate System is:
GEOGCS["Unknown datum based upon the Clarke 1866 ellipsoid",
    DATUM["Not specified (based on Clarke 1866 spheroid)",
        SPHEROID["Clarke 1866",6378206.4,294.9786982139006,
            AUTHORITY["EPSG","7008"]]],
    PRIMEM["Greenwich",0],
    UNIT["degree",0.0174532925199433]]
Origin = (-10.001388888888888,45.001388888888890)
Pixel Size = (0.002777777777778,-0.002777777777778)

But this is odd. I was suppose to get Plate-Carrée with geographic 
Lat/Long and Ref ellipsoid
 WGS 84 Spherical Radius= Equatorial Radius=Re= 6378,14km)

Why am I no obtaining this information? Nevertheless, has this any 
impact or shall I use *-s_srs and define it do Plate Carée (EPSG:??) ?
*Thanks
Antonio
