Geodesy

Geodesy is a science that deals with the Earth's shape, size, orientation, and gravity field, as well as the changes in these properties over time. Think of it as a specialist field that helps us understand our planet better. It has practical applications, too. For instance, geodesists' work helps us build better maps, ensures satellite navigation systems like GPS are accurate, and helps track movements in the Earth's crust that can cause natural disasters such as earthquakes. So, despite its complex nature, geodesy has a real-world impact that affects our everyday lives.
