Why has 82°80e been selected as the standard meridiam of india?
Answers
India is a vast country. Lying entirely in the Northern hemisphere the mainland extends between latitudes 8°4′N and 37°6′N and longitudes 68°7′E and 97°25′E. The Tropic of Cancer (23° 30′N) divides the country into almost two equal parts.
The latitudinal and longitudinal extent of the mainland is about 30°. Despite this fact the east-west extent appears to be smaller than the north-south extent.
From Gujarat to Arunachal Pradesh there is a time lag of two hours. Hence, time along the Standard Meridian of India (82°30′E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country.
82°30' E has been selected as the Standard Meridian of India because it is situated in the center of all longitudes and latitudes in which our country is located.
