Question

short note:prime meridian​

Answer 1

Answer:

• A prime meridian is the meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid into two hemispheres.

The prime meridian is the line drawn north to south at 0° (0 degrees) longitude. It is an imaginary line on Earth that passes north to south through the Greenwich Observatory in London, England. Sentences: The prime meridian divides Earth into the Eastern Hemisphere and the Western Hemisphere.

To avoid this confusion a longitude passing through the midpoint of 68 degrees 7' East (western most longitude) and 97 degrees 25' East (eastern most longitude) is taken as the standard prime meridian of India (i.e. 82 degrees30').
