Longitude
The east-west coordinate of a location, measured in degrees from the prime meridian. Longitude, together with latitude, precisely locates features on the earth’s surface.
How do you define Longitude?
A geographic coordinate known as longitude indicates a point's east-west location on the surface of the Earth. It is expressed in degrees (°) from the Prime Meridian, which passes through Greenwich, England, and is known as 0° longitude.
0° to 180° east and 0° to 180° west of the Prime Meridian are the main points.
Another name for lines of longitude is meridians.
Meridians are not parallel like latitude lines; rather, they converge at the poles.
When combined with latitude, it allows GPS systems and maps to pinpoint exact locations.
An example would be a place located 75 degrees east of the Prime Meridian at 75°E longitude.
Longitude is crucial for geospatial research, mapping, and navigation since it helps determine the horizontal positioning of every location on Earth.

Latitude, expressed in degrees (°), is the angular separation of a location north or south of the Equator. On a map or globe, it is represented by horizontal lines that extend from 0° at the Equator to 90° at the poles.
In geography and navigation, a meridian is an imaginary line on Earth that connects the North and South Poles and is used to determine longitude. With the Prime Meridian (0° longitude) traveling through Greenwich, England, acting as the reference point, each meridian aids in determining time zones and locations throughout the world.
The planet's zero line of longitude, the Prime Meridian, passes through Greenwich, London, and connects the North and South Poles. It is crucial for international navigation and timekeeping since it is the foundation of Coordinated Universal Time (UTC) and the reference point for measuring longitude east and west.
The northernmost point of our world is the North Pole, which is situated at the top of the axis. It is located in the centre of the Arctic Ocean, covered by fluctuating sea ice, and has six months of nonstop brightness and six months of darkness. It has a distinct and ever-changing habitat because, unlike the South Pole, it is not surrounded by any landmass.
