Terrestrial reference system
A terrestrial reference system is a standardized framework used to define precise locations on Earth’s surface. It provides a consistent way to measure positions, directions, and distances, accounting for Earth's shape, rotation, and movement. This system is essential for mapping, navigation, and scientific studies, ensuring that locations are accurately identified and shared worldwide. Think of it as an invisible grid that helps us pinpoint exact spots on our planet with high precision, even as Earth shifts and changes over time.
