Reasons for taking 82 1/2 as the standard meridian of India:
- Historical significance: The 82 1/2 degrees east longitude was chosen as the standard meridian of India during the British colonial rule. It was established as the reference point for all geographical measurements and time calculations in the country.
- Central location: The 82 1/2 meridian passes through the city of Allahabad, which is considered a central location in India. This meridian divides the country into two almost equal halves, making it a convenient reference point for mapping and administrative purposes.
- Uniform time zone: By adopting the 82 1/2 meridian as the standard, India was able to establish a single time zone for the entire country. This helped in simplifying timekeeping and coordination across different regions.
- International coordination: Choosing 82 1/2 as the standard meridian of India also helped in aligning the country's geographic coordinates with international standards. This facilitated easier communication, transportation, and trade relations with other countries.
Overall, the selection of 82 1/2 degrees east longitude as the standard meridian of India was based on a combination of historical precedent, geographical considerations, administrative convenience, and international coordination.
