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

Chile
–
Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about 1,250,000 square kilometres of Antarctica, the arid Atacama Desert in northern Chile contains great mineral wealth, principally copper. Southern Chile is rich in forests and grazing lands, and features a string of volcanoes and lakes, the southern coast is a labyrinth of fjords, inlets, canals, twisting peninsulas, and islands. Spain conquered and colonized Chile in the century, replacing Inca rule in northern and central Chile. After declaring its independence from Spain in 1818, Chile emerged in the 1830s as a relatively stable authoritarian republic, in the 1960s and 1970s the country experienced severe left-right political polarization and turmoil. The regime, headed by Augusto Pinochet, ended in 1990 after it lost a referendum in 1988 and was succeeded by a coalition which ruled through four presidencies until 2010. Chile is today one of South Americas most stable and prosperous nations and it leads Latin American nations in rankings of human development, competitiveness, income per capita, globalization, state of peace, economic freedom, and low perception of corruption. It also ranks high regionally in sustainability of the state, Chile is a founding member of the United Nations, the Union of South American Nations and the Community of Latin American and Caribbean States. There are various theories about the origin of the word Chile, another theory points to the similarity of the valley of the Aconcagua with that of the Casma Valley in Peru, where there was a town and valley named Chili. Another origin attributed to chilli is the onomatopoeic cheele-cheele—the Mapuche imitation of the warble of a locally known as trile. The Spanish conquistadors heard about this name from the Incas, ultimately, Almagro is credited with the universalization of the name Chile, after naming the Mapocho valley as such. The older spelling Chili was in use in English until at least 1900 before switching over to Chile, stone tool evidence indicates humans sporadically frequented the Monte Verde valley area as long as 18,500 years ago. About 10,000 years ago, migrating Native Americans settled in fertile valleys, settlement sites from very early human habitation include Monte Verde, Cueva del Milodon and the Pali Aike Craters lava tube. They fought against the Sapa Inca Tupac Yupanqui and his army, the result of the bloody three-day confrontation known as the Battle of the Maule was that the Inca conquest of the territories of Chile ended at the Maule river. The next Europeans to reach Chile were Diego de Almagro and his band of Spanish conquistadors, the Spanish encountered various cultures that supported themselves principally through slash-and-burn agriculture and hunting. The conquest of Chile began in earnest in 1540 and was carried out by Pedro de Valdivia, one of Francisco Pizarros lieutenants, who founded the city of Santiago on 12 February 1541. Although the Spanish did not find the gold and silver they sought, they recognized the agricultural potential of Chiles central valley

Regions of Chile
–
Chile is divided into 15 regions, which are the countrys first-level administrative division. Each region is headed by an intendant, appointed by the President, regions are divided into provinces, each headed by a governor, appointed by the President.

With the creation of regions XIV in the south and XV in the north in 2007, the administrative divisions of Chile were created in 1974 and limited to 13 regions. Previously, Chile was divided into 25 provinces, which were divided into departments. The new territorial organization was implemented in phases with some initial pilot regions beginning to operate in 1974, the Santiago Metropolitan Region began to operate in April 1980. Both regions became operative in October 2007, communes of Chile ISO 3166-2, CL Provinces of Chile

Municipality
–
It is to be distinguished from the county, which may encompass rural territory and/or numerous small communities such as towns, villages and hamlets. The term municipality may also mean the governing or ruling body of a given municipality, a municipality is a general-purpose administrative subdivision, as opposed to a special-purpose district. The term is derived from French municipalité and Latin municipalis, a municipality can be any political jurisdiction from a sovereign state, such as the Principality of Monaco, or a small village, such as West Hampton Dunes, New York. The power of municipalities range from virtual autonomy to complete subordination to the state, municipalities may have the right to tax individuals and corporations with income tax, property tax, and corporate income tax, but may also receive substantial funding from the state. Similar terms include Spanish ayuntamiento, also called municipalidad, Polish gmina, Dutch/Flemish Gemeente, in Australia, the term local government area is used in place of the generic municipality. Here, the LGA Structure covers only incorporated areas of Australia, incorporated areas are legally designated parts of states and territories over which incorporated local governing bodies have responsibility. In Canada, municipalities are local governments established through provincial and territorial legislation, the Province of Ontario has different tiers of municipalities, including lower, upper, and single tiers. Types of upper tier municipalities in Ontario include counties and regional municipalities, nova Scotia also has regional municipalities, which include cities, counties, districts, or towns as municipal units. In India, a Nagar Palika or Municipality is a local body that administers a city of population 100,000 or more. Under the Panchayati Raj system, it directly with the state government. Generally, smaller cities and bigger towns have a Nagar Palika. Nagar Palikas are also a form of local self-government entrusted with duties and responsibilities. Such a corporation in Great Britain consists of a head as a mayor or provost, since local government reorganisation, the unit in England, Northern Ireland and Wales is known as a district, and in Scotland as a council area. A district may be awarded borough or city status, or can retain its district title, in Jersey, a municipality refers to the honorary officials elected to run each of the 12 parishes into which it is subdivided. This is the highest level of government in this jurisdiction.

Rural area
–
In general, a rural area or countryside is a geographic area that is located outside towns and cities. Whatever is not urban is considered rural, typical rural areas have a low population density and small settlements. Agricultural areas are rural, though so are others such as forests. Different countries have varying definitions of rural for statistical and administrative purposes, in Canada, the census division has been used to represent regions and census consolidated sub-divisions have been used to represent communities. Intermediate regions have 15 to 49 percent of their living in a rural community. Predominantly urban regions have less than 15 percent of their living in a rural community. Predominantly rural regions are classified as rural metro-adjacent, rural non-metro-adjacent and rural northern, following Ehrensaft, as well, rural northern regions encompass all of the Yukon, Northwest Territories and Nunavut. Statistics Canada defines rural for their population counts and this definition has changed over time. Typically, it has referred to the population living outside settlements of 1,000 or less inhabitants, the current definition states that census rural is the population outside settlements with fewer than 1,000 inhabitants and a population density below 400 people per square kilometre. 84% of the United States inhabitants live in suburban and urban areas, Rural areas occupy the remaining 90 percent. The U. S. Census Bureau, the USDAs Economic Research Service, an urbanized area consists of a central surrounding areas whose population is greater than 50,000. USDA The USDAs Office of Rural Development may define rural by various population thresholds, for example, a metropolitan county is one that contains an urbanized area, or one that has a twenty-five percent commuter rate to an urbanized area regardless of population. In 2014, the USDA updated their rural / non-rural area definitions based on the 2010 Census counts, Rural health definitions can be different for establishing under-served areas or health care accessibility in rural areas of the United States. This became the Goldsmith Modification definition of rural, health care delivery in rural areas of the United States can be challenging. From 2005-2011, the rate of potentially preventable hospitalizations for acute conditions was highest in rural areas, in Brazil, theres different notions of rural area and countryside. Rural areas are any place outside an urban development and its carried by informal usage. Otherwise, countryside are officially defined as all municipalities outside the capitals metropolitan region. Some states as Mato Grosso do Sul doesnt have any metropolitan region, thus all of the state, Rio de Janeiro is singular in Brazil and its de facto a metropolitan state, as circa 70% of its population are located in Greater Rio
