The Indian subcontinent has been historically divided into various geographical regions based on its geographical features. To determine the longitude and latitude of these regions, a standard meridian is necessary. The standard meridian of India is 82.30′ East and is used to measure the longitude and latitude of different parts of the country. In this article, we will discuss why 82.30′ was chosen as the standard meridian of India.
Selection of Standard Meridian of India
The selection of a standard meridian of India is based on the geographical features of the country. The standard meridian of India was chosen in 1802 by the British Surveyor General, William Lambton, who was in charge of the Great Trigonometric Survey of India. Lambton chose the longitude of 82.30′ East for the standard meridian of India based on the geographical features of the country. This was done to make the survey easier as it would reduce the number of meridians that had to be measured.
Reason Behind the Choice of 82.30′
The reason behind the choice of 82.30′ as the standard meridian of India is based on the geographical features of the country. The longitude of 82.30′ East was chosen as it passes through the central part of the country, which makes it easier to measure the longitude and latitude of various parts of the country. Additionally, the longitude of 82.30′ East passes through the city of Allahabad, which is considered to be the cultural and political center of the country. This makes it easier to measure the longitude and latitude of various parts of the country without having to measure the entire length of the country.
In conclusion, 82.30′ East was chosen as the standard meridian of India based on the geographical features of the country and its cultural and political significance. This makes it easier to measure the longitude and latitude of different parts of the country without having to measure the entire length of the country. The selection of the standard meridian of India has made it easier to measure the longitude and latitude of the country and has enabled the country to be divided into various geographical regions.
