Where do I find the latitude and longitude gain or loss of arbitrary points not relative to the African Plate but to the rotation axis and whatever is the official longitude? Does the official prime meridian move every time the European plate moves or is it fixed to Greenwich Observatory? {{unsigned|Oxygen|19:46, 29 January 2024}} | Where do I find the latitude and longitude gain or loss of arbitrary points not relative to the African Plate but to the rotation axis and whatever is the official longitude?
