Kuyini ukuhlola umhlaba?
I-Geodesy yisayensi yokulinganisa nokumelela i-geometry, amandla adonsela phansi, nokuma kwendawo yoMhlaba ku-3D eguquguqukayo ngokwesikhathi. Kubizwa ngokuthi i-planetary geodesy lapho kufundwa ezinye izindikimba zezinkanyezi, njengamaplanethi noma izinhlelo ze-circumplanetary.  Izenzakalo ze-geodynamic, kuhlanganise nokunyakaza kwe-crustal, amagagasi, nokunyakaza kwe-polar, zingafundwa ngokwakha amanethiwekhi okulawula omhlaba wonke nawesizwe, ukusebenzisa i-space geodesy namasu we-terrestrial geodetic, nokuthembela kuma-datums nezinhlelo zokuxhumanisa. Iziqu zomsebenzi ziyi-geodesist nomhloli wezwe.
