Chii chinonzi geodesy?
Geodesy ndiyo sayenzi yokuyera nokumirira geometry, giravhiti, uye nzvimbo yokuratidzira yePasi mu3D inochinja nguva nenguva. Kunonzi geodesy yemapuraneti pakudzidza zvimwe zvinhu zvomuchadenga, zvakadai semapuraneti kana kuti masisitimu anodzora mapuraneti.  Zviitiko zve geodynamic, kubatanidza kufamba kwe crustal, tides, uye polar motion, zvinogona kudzidzwa nekugadzira pasi rose uye yenyika kutonga network, kushandisa nzvimbo geodesy uye terrestrial geodetic matekiniki, uye kuvimba nedatum uye kurongedza masisitimu. Mazita ebasa ndeokuti geodesist uye geodetic surveyor.
