Hello,
I've just tried to render the Earth using 'isosurface' of POV-Ray 3.5.

The pov code for the Earth is below, and the image map files were
obtained from http://apollo.spaceports.com/~jhasting/earth.html
which has been recently discussed in povray.general.

#declare Ebump=function{ 
  pigment { 
    image_map {jpeg "earthbump1k.jpg" 
      map_type 1        
      interpolate 2     
    } 
  }
}

isosurface{
  function{f_sphere(x,y,z,1)-Ebump(x,y,z).gray*0.05 }
  contained_by{sphere{0,1.05}}
  texture {
    pigment {
       image_map {jpeg "earthmap1k.jpg" 
         map_type 1        
         interpolate 2     
       } 
    } 
  }
}
