The Prime Meridian, located at 0 degrees longitude, is the reference line for longitude. It runs from the North Pole to the South Pole and passes through Greenwich, London. Longitude lines, or meridians, measure the distance east or west of the Prime Meridian up to 180 degrees.

What are the reference point for latitude and longitude?
The latitude and longitude references are lines, not points. The reference for latitude is the line that forms a circle and consists of all points with zero latitude. That line is called the "equator". The reference for longitude is the line that forms a semi-circle and consists of all points with zero longitude. That line is called the "Prime Meridian".
What is the reference line when determining the longitude?
The Prime Meridian is the reference line. That's the meridian of longitude that joins the north and south poles and passes through a mark on the floor of the transit room of the Royal Observatory at Greenwich, a suburb of London. By international agreement, that line is zero longitude. All others are measured east or west from it, from zero to 180°.
What is the reference line of longitude and what are the degrees?
The reference line of longitude is the Prime Meridian, which is designated as 0 degrees longitude. It runs from the North Pole to the South Pole and passes through Greenwich, England. Longitude is measured in degrees east or west from the Prime Meridian, extending up to 180 degrees in either direction.
What is meridian line of 0' longitude?
The "Prime Meridian" ... the one that passes through the Royal Observatory in Greenwich UK ... is the zero reference for longitude.
Difference between meridian and longitude?
The longitude of a point on earth is the angle, east or west, between that point and a certain reference line on the earth. If you take a globe or a map and draw a line through all the points that have exactly the same longitude, the line you get is the meridian of that longitude. The reference line is the meridian of zero longitude, called the "Prime Meridian". On that line are all the points on earth that have zero longitude. The line joins the north and south Poles, and passes through the Royal Observatory at Greenwich, a suburb of London.
Which longitude line is at 0 degrees?
The Prime Meridian is defined as the zero reference of longitude.
What is the beginning line a longitude?
By international agreement about 200 years ago, the zero-reference line of longitude is the Prime Meridian.

A meridian is a line of constant longitude.
What is the name given to the line of longitude with the smallest number?
The line of longitude with the smallest number is the Prime Meridian, which is designated as 0 degrees longitude. It runs vertically from the North Pole to the South Pole and serves as the reference point for measuring longitude east and west around the globe. The Prime Meridian passes through Greenwich, London, and is a key reference for time zones and navigation.
What is center line of longitude?
The center line of longitude is the line that runs from the North Pole to the South Pole and divides the Earth into eastern and western hemispheres. It is also known as the Prime Meridian, which passes through Greenwich, England, and is used as the reference point for measuring longitude.
