What is geodesy? Geodesy is the science of accurately measuring and understanding the Earth's geometric shape, orientation in space, and gravity field. Using GPS, geodesists can monitor the movement of a site (orientation in space and gravity field) 24/7.
Geodesy is the science of measuring Earth’s shape, gravity, and orientation — and it quietly powers GPS, climate tracking, and more.
A GPS unit and a Geographic Information System (GIS) program are a great team. With a GPS receiver in hand, you can tap into the network of government satellites to calculate your position on Earth to ...
Geodesy refers to the science of measuring and representing geospatial information, while geomatics encompasses practical applications of geodesy on local and regional scales, including surveying.

It is now possible to use satellites in conjunction with the land-based system to refine knowledge of the Earth’s shape and dimensions; this endeavour is sometimes termed satellite geodesy.
Geodesy provides the precise measurements needed to model the Earth’s surface in detail — its shape, elevation, and features. This knowledge forms the foundation for accurate maps, national borders, infrastructure planning and management, and environmental monitoring.
Geodesy is the science of accurately measuring the Earth's size, shape, orientation, mass distribution and how these vary with time. Gravity is determined by mass. Earth’s mass is not distributed equally, and it also changes over time.
In the last half-century, space techniques using extraterrestrial components and measurements have revolutionized the research and applications of geodesy, hence the term “space geodesy.”
