An Anti-Meridian is a meridian opposite any given meridian of longitude.
Specifically the Anti-Meridian is the 180th meridian. That is the meridian opposite of the Prime Meridian.
The term Anti-Meridian is sometimes confused with Ante Meridiem.
Ante Meridiem is latin for before noon. Usually shown in English as "a.m.". Similarly, post meridiem, after noon, is shown in English as "p.m.".
Longitudinal lines run from pole to pole, parallel to the Prime Meridian. They help locate positions east or west of the Prime Meridian on a map or globe.
Meridians run from north to south on the surface of the Earth, connecting the North Pole to the South Pole. They are the lines of longitude used in geospatial coordinate systems to indicate angular distance east or west from a prime meridian, such as the Greenwich Meridian.
The magnetic meridian in compass surveying is the line passing through a compass needle when it is freely suspended and allowed to align with the Earth's magnetic field. It represents the direction of the magnetic north pole at a particular location on the Earth's surface. It is an important reference in compass surveying for determining directions.
horizontal with its north pole pointing towards magnetic north.
Orienting the setup in the magnetic meridian helps ensure accuracy in experiments involving magnetic fields because it aligns the equipment with the Earth's magnetic field. This alignment reduces interference from external magnetic fields and produces more reliable results.
It was the ante meridian of the day.
