It's the Greenwich meridian
13 degrees 3 minutes north, 80 degrees 15 minutes east
The prime meridian in located at 0 degress longitude, and passes through Grenich, England.
The line of 0° longitude is called the prime meridian (it is also known as the Greenwich Meridian).The Prime Meridian
0 degrees longitude is called the Prime Meridian. It runs from the North pole to the South pole, passing through Greenwich Observatory in England. Greenwich was chosen by international agreement (largely due to it being the de facto standard anyway), though historically other conventions have been used.
0 degrees latitude is at the equator, while 50 degrees north latitude is located roughly in the middle of Europe, passing through countries like the United Kingdom, Germany, and Russia.
They're labeled E (or W) to show that they're (E)ast or (W)est of the prime meridian (which is the line of longitude passing through Greenwich Observatory near London). 15 degrees East and 15 degrees West are the same distance from the prime meridian, but in opposite directions.

Any measurement used in navigation, whether longitude or latitude, is based on the 360 degrees of a full circle. The Prime Meridian is a line of longitude that passes between the poles, passing through the Greenwich Observatory in London, and is zero. So, any measurements West or East of this line, will be in degrees (based on 360) and using minutes and seconds for finer location.
Difficult to explain without pictures, but here goes.... Imagine a circle drawn around the earth, from North to South and passing through both the North and South poles. This called a meridian, or Great Circle. A series of these circles can be drawn, each one being one degree apart, around the circle of the equator, and there would then be 360 such circles. The longitude of any place on earth is measured by how many degrees around is the meridian which passes through it. The starting point for this measurement could be anywhere on earth, but because of Britain's history as a major empire and sea power the starting point is in Greenwich, London. So, the longitude of Greenwich, London is 0 degrees.
