Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

The Part C states were Ajmer, Bhopal, Bilaspur, Coorg, Delhi, Himachal Pradesh, Cutch, Manipur, Tripura, the only Part D state was the Andaman and Nicobar Islands, which were administered by a lieutenant governor appointed by the central government. The Union Territory of Puducherry was created in 1954 comprising the previous French enclaves of Pondichéry, Karaikal, Yanam, Andhra State was created on 1 October 1953 from the Telugu-speaking northern districts of Madras State. The States Reorganisation Act of 1956 reorganised the states based on linguistic lines resulting in the creation of the new states, as a result of this act, Madras State retained its name with Kanyakumari district added to from Travancore-Cochin. Andhra Pradesh was created with the merger of Andhra State with the Telugu-speaking districts of Hyderabad State in 1956, kerala was created with the merger of Malabar district and the Kasaragod taluk of South Canara districts of Madras State with Travancore-Cochin. The Laccadive Islands which were divided between South Canara and Malabar districts of Madras State were united and organised into the territory of Lakshadweep. Bombay State was enlarged by the addition of Saurashtra State and Kutch State, Rajasthan and Punjab gained territories from Ajmer and Patiala and East Punjab States Union respectively and certain territories of Bihar was transferred to West Bengal. Bombay State was split into the states of Gujarat and Maharashtra on 1 May 1960 by the Bombay Reorganisation Act. Nagaland was formed on 1 December 1963, the Punjab Reorganisation Act of 1966 resulted in the creation of Haryana on 1 November and the transfer of the northern districts of Punjab to Himachal Pradesh. The act also designated Chandigarh as a territory and the shared capital of Punjab

According to 2011 census, Delhis city population was about 11 million, Delhis urban area is now considered to extend beyond the NCT boundary to include an estimated population of over 26 million people making it the worlds second largest urban area. As of 2016 recent estimates of the economy of its urban area have ranked Delhi either the top or second most productive metro area of India. Delhi is the second wealthiest city after Mumbai in India, with a wealth of $450 billion. Delhi has been inhabited since the 6th century BC. Through most of its history, Delhi has served as a capital of various kingdoms and it has been captured, ransacked and rebuilt several times, particularly during the medieval period, and modern Delhi is a cluster of a number of cities spread across the metropolitan region. New Delhi is jointly administered by the government of India and the local government of Delhi. Delhi is also the centre of the National Capital Region, which is a unique interstate regional planning area created by the National Capital Region Planning Board Act of 1985, Delhi ranks among the cities with the worst air pollution in the world. There are a number of myths and legends associated with the origin of the name Delhi, one of them is derived from Dhillu or Dilu, a king who built a city at this location in 50 BC and named it after himself. The coins in circulation in the region under the Tomaras were called dehliwal, according to the Bhavishya Purana, King Prithiviraja of Indraprastha built a new fort in the modern-day Purana Qila area for the convenience of all four castes in his kingdom. He ordered the construction of a gateway to the fort and later named the fort dehali, another theory suggests that the citys original name was Dhillika. The people of Delhi are referred to as Delhiites or Dilliwalas, the city is referenced in various idioms of the Northern Indo-Aryan languages. Dilli dilwalon ka shehr or Dilli Dilwalon ki meaning Delhi belongs to the large-hearted/daring, aas-paas barse, Dilli pani tarse, literally meaning it pours all around, while Delhi lies parched.
