To plot a certain East/West point on the Globe.

The same one the world uses. Latitude and longitude!
A map that uses latitude and longitude intersections is called a geographic or coordinate map. These maps display a grid system that helps in pinpointing exact locations on the Earth's surface by using coordinates expressed in degrees of latitude and longitude. This type of mapping is essential for navigation, geographic analysis, and understanding spatial relationships.
Cebu City is located in the Philippines. The latitude and longitude is 10-18'-40" N and 123-53'-30" E and uses the Asia/Manila time zone.
That is the center of the coordinate system, which uses latitude and longitude.
China is the country that extends over 50 degrees of longitude but operates on a single time zone. This results in a significant difference in local time between the western and eastern regions of the country.
Global Positioning System (GPS) uses timing signals from four satellites to determine your latitude,longitude, altitude and precise time.
Alphanumeric grid uses a combination of letters and numbers to identify locations on a map, while latitude and longitude use angular measurements. Alphanumeric grid is typically used in smaller, more localized areas, while latitude and longitude are used globally. Alphanumeric grids are often based on a specific reference point, while latitude and longitude are based on the equator and prime meridian. Alphanumeric grids may have different orientations or scales, while latitude and longitude are universally recognized.
GPS uses a coordinate system called WGS84, which stands for World Geodetic System 1984. This system uses latitude and longitude coordinates to pinpoint locations on Earth with high accuracy.
The military uses latitude and longitude coordinates to identify and pinpoint specific locations on the Earth's surface. This information is crucial for navigation, targeting, and coordinating operations in various environments and situations. By using latitude and longitude, the military can effectively communicate and share precise location data with personnel and units.
Together, latitude and longitude numbers can identify an exact position on Earth, giving its distance from the equator (latitude) and its relationship with the meridians that measure east and west (longitude). They were developed to provide uniform navigational information and can be determined using the calendar date and the known positions of stars. Latitude and longitude provide a "grid system" by which any location on Earth can be specified.
Different countries don't have different prime meridians. There is one Prime Meridian on Earth, and everybody uses the same one for their longitude measurements. The Prime Meridian passes through three continents, eight countries and several seas. North America is not one of the continents, and Canada is not one of the countries. The longitude of the Prime Meridian ... by international definition and agreement ... is zero.
