WebWGS84 is not outdated; it's just a simplified mathematical model used by positioning systems like GPS, even if a geoid is technically more accurate when it comes to define the height over the sea level (since this is different from GPS altitude). You just have to translate coordinates when you need such distinction.

You can visualize the geoid as the surface of the ocean without effects such as weather, waves, and land. The Earth Gravitational Model of 1996 (EGM96) is based on the ellipsoid specified by the World Geodetic System of 1984 (WGS84), so the … WebThis is the HAE altitude (height above the ellipsoid). The HAE altitude of airports with GPS approaches is stored in the GPS database. The actual MSL surface is the earth’s geoid (a surface of constant gravitational pull, and matching the mean surface of the seas), so to convert HAE altitude to MSL you need to add or subtract the local value ... drumwit viajes
