I am new to GIS, trying to read the GeoRef System for VMap by using the following code:

    OGRSpatialReference *ref = layer->GetSpatialRef();

    if( ref )
    {
        QString georefSystem = ref->GetAttrValue( "GEOGCS" );
    }

its reading and returning as NAD83 for the map which is WGS84. I confirmed the map is WGS84 by opening it in global mapper.

please let me know what I am missing here to get the correct Geo reference system.

My work environment is C++ in Windows 7.

Thanks, Prady
