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

Colombia
–
Colombia, officially the Republic of Colombia, is a transcontinental country largely situated in the northwest of South America, with territories in Central America. Colombia shares a border to the northwest with Panama, to the east with Venezuela and Brazil and to the south with Ecuador and it shares its maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, Haiti and the Dominican Republic. It is a unitary, constitutional republic comprising thirty-two departments, the territory of what is now Colombia was originally inhabited by indigenous peoples including the Muisca, the Quimbaya and the Tairona. The Spanish arrived in 1499 and initiated a period of conquest and colonization ultimately creating the Viceroyalty of New Granada, independence from Spain was won in 1819, but by 1830 the Gran Colombia Federation was dissolved. What is now Colombia and Panama emerged as the Republic of New Granada, the new nation experimented with federalism as the Granadine Confederation, and then the United States of Colombia, before the Republic of Colombia was finally declared in 1886. Since the 1960s the country has suffered from an asymmetric low-intensity armed conflict, Colombia is one of the most ethnically and linguistically diverse countries in the world, and thereby possesses a rich cultural heritage. Cultural diversity has also influenced by Colombias varied geography. The urban centres are located in the highlands of the Andes mountains. Colombian territory also encompasses Amazon rainforest, tropical grassland and both Caribbean and Pacific coastlines, ecologically, it is one of the worlds 17 megadiverse countries, and the most densely biodiverse of these per square kilometer. Colombia is a power and a regional actor with the fourth-largest economy in Latin America, is part of the CIVETS group of six leading emerging markets and is an accessing member to the OECD. Colombia has an economy with macroeconomic stability and favorable growth prospects in the long run. The name Colombia is derived from the last name of Christopher Columbus and it was conceived by the Venezuelan revolutionary Francisco de Miranda as a reference to all the New World, but especially to those portions under Spanish and Portuguese rule. The name was adopted by the Republic of Colombia of 1819. When Venezuela, Ecuador and Cundinamarca came to exist as independent states, New Granada officially changed its name in 1858 to the Granadine Confederation. In 1863 the name was changed, this time to United States of Colombia. To refer to country, the Colombian government uses the terms Colombia. Owing to its location, the present territory of Colombia was a corridor of early human migration from Mesoamerica, the oldest archaeological finds are from the Pubenza and El Totumo sites in the Magdalena Valley 100 km southwest of Bogotá. These sites date from the Paleoindian period, at Puerto Hormiga and other sites, traces from the Archaic Period have been found

Departments of Colombia
–
Colombia is a unitary republic formed by thirty-two departments and a Capital District. Each department has a Governor and a Department Assembly, elected by popular vote for a four-year period, the governor cannot be re-elected in consecutive periods. Departments are country subdivisions and are granted a degree of autonomy. Departments are formed by a grouping of municipalities, Municipal government is headed by mayor and administered by a Municipal Council, both of which are elected for four-year periods. Each one of the departments of Colombia in the map below links to a corresponding article, current governors serving four-year terms from 2015 to 2019 are also shown, along with their respective political party or coalition. Estimate for Cundinamarca includes the capital, Bogotá. The indigenous territories are at the level of administrative division in Colombia. Indigenous territories are created by agreement between the government and indigenous communities, also indigenous territories may achieve local autonomy if they meet the requirements of the law. Article 329 of the 1991 constitution recognizes the collective ownership of indigenous territories. Decree 2164 of 1995 interprets Law 160 of 1994, providing, among other things, indigenous territories in Colombia are mostly in the departments of Amazonas, Cauca, La Guajira, Guaviare and Vaupés. When it was first established in 1819, República de la Gran Colombia had three departments, in 1824 the Distrito del Centro was divided into five departments, and further divided into seventeen provices. One department, Istmo Department, consisting of two later became Panama. With the dissolution of Gran Colombia in 1826 by the Revolution of the Morrocoyes, in 1832 the provinces of Vélez and Barbacoas were created, and in 1835 those of Buenaventura and Pasto were added. In 1843 those of Cauca, Mompós and Túquerres were created, at this time the cantons and parish districts were created, which provided the basis for the present-day municipalities. However, the new constitution of 1853 introduced federalism, which lead to the consolidation of provinces into states,1861 saw the creation of the final federal state of Tolima. The Colombian Constitution of 1886 converted the states of Colombia into departments, with the state presidents renamed as governors

Cundinamarca Department
–
Department of Cundinamarca is one of the departments of Colombia. Its area covers 22,623 square kilometres and it has a population of 2,598,245 as of 2013 and it was created on August 5,1886 under the constitutional terms presented on the same year. Cundinamarca is located in the center of Colombia, Cundinamarcas capital city is Bogotá, the capital of Colombia. This is a case among Colombian departments, since Bogotá is not legally a part of Cundinamarca. In censuses, the populations for Bogotá and Cundinamarca are tabulated separately, otherwise, the capital district of Bogotá is nearly completely surrounded by Cundinamarca territory and was formed by carving up Cundinamarca. Because of this and other changes, the present department of Cundinamarca is much smaller than the original state. According to the latest census conducted in 2005,2,280,037 people live in Cundinamarca, excluding 6,776,009 of the capital, the racial makeup is, Whites and mestizos, Mestizos are mixed European-Amerindian blood. The Bogotá metropolitan area has a history of European and other Latin American immigration, blacks or Afro-Colombians Indigenous/Amerindians Roma East Asians, often of Chinese descent. About 25,000 Chinese-Colombians live in the department, the city of Bogotá and the municipalities of Soacha, La Calera, Cota, Chía, Madrid, Funza, Mosquera, Fusagasugá, Facatativá and Zipaquirá form a single metropolitan area. Bogotá Metropolitan Area, Comprises the towns of Soacha, Facatativá, Chia, Madrid, Funza and its activities are centered in the industrial sector. Estate activity is important especially in the closer to Bogotá, Chía, La Calera. Girardot, In the far southwest and bordering Department of Tolima, is the capital of the Province of Alto Magdalena and its main economic activity is trade, as a result of a major tourist dynamics and its proximity to major agricultural areas of Tolima. It has a college and important trade fairs and events, Fusagasugá is located between Bogotá and Girardot, and it is an hour of each city. Its economy is focused on trade and agricultural marketing, with a significant production of ornamental plants and flowers for export. Zipaquirá, Despite being part of the area of Bogotá. Its economy is focused on commerce and services, other major towns are Ubaté due to high livestock and dairy production. Guaduas, is an important cultural center, chocontá and Fred are agricultural centers. Cundinamarca has 15 provinces and the Capital District, which acts as capital of the Republic, capital of the Department
