¨ Ep!

¨ where is the zero point of "sea level" (gps coordinates) ????
¨
¨ in what sea/ocean ????
¨
¨ in what point ???
¨ I think the reference is not a point but a surface, the geoid surface, which
¨ is an oblate spheroid that is determined I think by measuring the gravity (I
¨ don't know how, thpough). This gives 0 meter altitude.
¨
¨
¨ how is measured altitude of mountains ?
¨
¨ how mach meters have the Gaorisankar (Everest) ???
¨ some people say 8.848 others 8.850... what is correct ???
¨
¨ Actually the Chinese are just sending a mission to determine the new height
¨ of the Everest, since it is believed that Everest snow cap is melting down
¨ due to global warming.
