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 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 geographic meridian?
A geographic meridian is an imaginary line that connects the North Pole with the South Pole. It is used as a reference point for determining longitude on Earth, with the Prime Meridian (located in Greenwich, England) being the most commonly used meridian.
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.
How would you describe the Prime Meridian?
The Prime Meridian is the line of longitude marked at 0 degrees, from which all other lines of longitude are measured. It passes through Greenwich, England and serves as the reference point for determining time zones across the world.
What is the name of the starting line for determining longitude?

What is the 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°.
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.
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".
Is the equator located at 0 longitude 0latitude or 180 longitude?
The equator is defined as the zero reference line of latitude.
What is the reference point for lines longitude and where is it?
The reference for longitude ... the definition of 'zero' longitude ... is the Prime Meridian. That imaginary line joins the north and south poles, and runs through Greenwich, a suburb of London, UK.
What is the significance of the Greenwich Line in determining time zones around the world?
The Greenwich Line, also known as the Prime Meridian, is significant in determining time zones around the world because it serves as the starting point for measuring longitude. Time zones are based on lines of longitude, and the Greenwich Line helps establish a standard reference point for coordinating time across different regions. This allows for a consistent and globally recognized system of timekeeping.
