Earth geoid
WebJul 10, 2024 · The surface of a geoid represents a Mean Sea Level (MSL), or a conjecture of the ocean’s surface if tides, winds, and other factors that affect its movements didn’t exist. The only factor that affects the MSL’s shape is the earth’s gravity field. WebBy definition, the geoid describes the irregular shape of the earth and is the true zero surface for measuring elevations. Because the geoid surface cannot be directly observed, heights above or below the geoid surface …
