Pacific Ocean
–
The Pacific Ocean is the largest and deepest of the Earths oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west, the Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres. Both the center of the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean, the oceans current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favourable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means peaceful sea, important human migrations occurred in the Pacific in prehistoric times. Long-distance trade developed all along the coast from Mozambique to Japan, trade, and therefore knowledge, extended to the Indonesian islands but apparently not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality, from 1404 to 1433 Zheng He led expeditions into the Indian Ocean. The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and he named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. Later, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Castilian expedition of world circumnavigation starting in 1519, Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters. The ocean was often called the Sea of Magellan in his honor until the eighteenth century, sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, and Papua New Guinea. In 1542–43 the Portuguese also reached Japan, in 1564, five Spanish ships consisting of 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi and sailed to the Philippines and Mariana Islands. The Manila galleons operated for two and a half centuries linking Manila and Acapulco, in one of the longest trade routes in history, Spanish expeditions also discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, and the Admiralty Islands in the South Pacific. In the 16th and 17th century Spain considered the Pacific Ocean a Mare clausum—a sea closed to other naval powers, as the only known entrance from the Atlantic the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western end of the Pacific Ocean the Dutch threatened the Spanish Philippines, Spain also sent expeditions to the Pacific Northwest reaching Vancouver Island in southern Canada, and Alaska. The French explored and settled Polynesia, and the British made three voyages with James Cook to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest, one of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789–1794. It sailed vast areas of the Pacific, from Cape Horn to Alaska, Guam and the Philippines, New Zealand, Australia, and the South Pacific. Growing imperialism during the 19th century resulted in the occupation of much of Oceania by other European powers, and later, Japan, in Oceania, France got a leading position as imperial power after making Tahiti and New Caledonia protectorates in 1842 and 1853 respectively. After navy visits to Easter Island in 1875 and 1887, Chilean navy officer Policarpo Toro managed to negotiate an incorporation of the island into Chile with native Rapanui in 1888, by occupying Easter Island, Chile joined the imperial nations

Geography of Tonga
–
Located in Oceania, Tonga is an archipelago in the South Pacific Ocean, directly south of Samoa and about two-thirds of the way from Hawaii to New Zealand. It has 169 islands,36 of them inhabited, are divided into three main groups – Vavau, Haapai, and Tongatapu – and cover an 800-kilometre -long north-south line. The largest island, Tongatapu, on which the city of Nukuʻalofa is located. Geologically the Tongan islands are of two types, most have a limestone formed from uplifted coral formations, others consist of limestone overlaying a volcanic base. The climate is tropical with a warm period, during which the temperatures rise above 32 °C. The temperature increases from 23 to 27 °C, and the rainfall is from 1,700 to 2,970 millimetres as one moves from Tongatapu in the south to the more northerly islands closer to the Equator. The average wettest period is around March with on average 263 mm, the average daily humidity is 80%. Though administratively divided into the three island groups of Tongatapu, Haapai, and Vavau, the Tonga archipelago is actually made of two geologically different parallel chains of islands. The western islands, such as Ata, Fonuafoou, Tofua, Kao, Lataiki, Late, Fonualei, Toku, Niuatoputapu and they were created from the subduction of the western-moving Pacific plate under the Australia-India plate at the Tonga Trench. The Tongan Islands sit on the Australia-India plate just west of the Tonga Trench and these volcanoes are formed when materials in the descending Pacific plate heat and rise to the surface. There is only limited coral reef development on these islands, except for Niuatoputapu, the eastern islands are nonvolcanic and sit above the mostly submerged Tonga ridge that runs parallel to the Tongan Volcanic Arch and the Tongan Trench. Of these islands, only Eua has risen high enough to expose its underlying Eocene volcanic bedrock, also, the andesite/basalt from the volcanoes were initially used as hammerstones, weaving weights, cooking stones, and decorative pebbles for grave decoration. Tafahi island in the far north provided volcanic glass to initial human settlers, in December 2014 and January 2015, a volcanic island 1 km wide by 2 km long was created adjacent to the island of Hunga Haapai 65 kilometers northwest of Nukualofa. The volcanic eruption has built the new island to a height of 100 m composed of ash and large rock fragments

Tonga
–
Tonga, officially the Kingdom of Tonga, is a Polynesian sovereign state and archipelago comprising 169 islands of which 36 are inhabited. The total surface area is about 750 square kilometres scattered over 700,000 square kilometres of the southern Pacific Ocean and it has a population of 103,000 people of whom 70% reside on the main island of Tongatapu. Tonga stretches across approximately 800 kilometres in a north-south line and it is surrounded by Fiji and Wallis and Futuna to the northwest, Samoa to the northeast, Niue to the east, Kermadec to the southwest, and New Caledonia and Vanuatu to the farther west. Tonga became known in the West as the Friendly Islands because of the reception accorded to Captain James Cook on his first visit in 1773. He arrived at the time of the festival, the yearly donation of the First Fruits to the Tuʻi Tonga. According to the writer William Mariner, the wanted to kill Cook during the gathering. From 1900 to 1970, Tonga had British protected state status, the country never relinquished its sovereignty to any foreign power. In many Polynesian languages including Tongan, the word tonga means south, the name of Tonga is cognate to the Hawaiian region of Kona. In Malay, the name of Tonga is also cognate to the word Tenggara, an Austronesian-speaking group linked to the archaeological construct known as the Lapita cultural complex reached and inhabited Tonga around 1500–1000 BCE. Scholars have much debated the exact dates of the settlement of Tonga. Not much is known before European contact because of the lack of a writing system, in the 15th century and again in the 17th, civil war erupted. The Tongan people first encountered Europeans in 1616 when the Dutch vessel Eendracht, captained by Willem Schouten, later came other Dutch explorers, including Jacob Le Maire, and in 1643 Abel Tasman. In 1845, the young warrior, strategist, and orator Tāufaʻāhau united Tonga into a kingdom. He held the title of Tuʻi Kanokupolu, but had been baptised by Methodist missionaries with the name Siaosi in 1831. Tonga became a state under a Treaty of Friendship with Britain on 18 May 1900. The treaty posted no higher permanent representative on Tonga than a British Consul, under the protection of Britain, Tonga maintained its sovereignty, and remained the only Pacific nation to retain its monarchical government. The Tongan monarchy follows a succession of hereditary rulers from one family. The 1918 flu pandemic, brought to Tonga by a ship from New Zealand, killed 1,800 Tongans, the Treaty of Friendship and Tongas protection status ended in 1970 under arrangements established by Queen Salote Tupou III prior to her death in 1965

Tongatapu
–
Tongatapu is the main island of the Kingdom of Tonga and the location of its capital Nukuʻalofa. Its maximum height is 65 metres, Tongatapu is Tongas centre of government and the seat of its monarchy. Tongatapu, as a commercial and transport hub, has experienced rapid economic development than, as well as attracting many internal migrants from. The island is 257.03 square kilometres and rather flat, the island is covered with thick fertile soil consisting of volcanic ash from neighboring volcanoes. At the steep coast of the south, heights reach an average of 35 metres gradually decreasing towards the north, Tongatapu is highest in elevation around the villages of Fuaamotu and Nakolo with a height of 65 metres. North of the island are small isolated islands and coral reefs which extend up to 7 kilometres from Tongatapus shores. The almost completely closed Fangauta and Fangakakau Lagoons are important breeding grounds for birds, the lagoons were declared a Natural Reserve in 1974 by the government. The island has only but a few sandy beaches because of its raised coastlines apart from the small islands in the north boasting some of the best beaches in Tongatapu. Tongatapu has a cooler climate than the rest of Tonga as it is the southernmost group of islands in the country. Because of this, fruit production is lower in Tongatapu than it is in the islands in the north. Tongatapu is known as having one of the highest concentration of remains in the Pacific. The earliest traces of Lapita pottery found in Tonga was from around 900–850 BCE,300 years after the first settlements in Tonga were established. Archaeologist David Burley discovered the pottery around the Fangauta Lagoon,2,000 kilometres away from the Lapita pottery found at Santa Cruz in the Solomon Islands. Although Tonga was always the seat of the Tongan Empire, but in an area of distances up to 1,000 kilometres, it was often only a symbolic rule. Tongatapu was discovered by Europeans on 20 January 1643 by Abel Janszoon Tasman commanding two ships, the Heemskerck and the Zeehaen commissioned by the Dutch East India Company of Batavia. The expeditions goals were to chart the southern and eastern seas and to find a possible passage through the South Pacific. The expedition set sail from Batavia on 14 August 1642, Tasman named the island t’ Eijlandt Amsterdam, because of its abundance of supplies. This name is no longer used except by historians, resolution, under British sea captain James Cook, stopped here in 1777 and left some cattle for breeding

Humpback whale
–
The humpback whale is a species of baleen whale. One of the larger species, adults range in length from 12–16 m. The humpback has a body shape, with long pectoral fins. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers, males produce a complex song lasting 10 to 20 minutes, which they repeat for hours at a time. Its purpose is not clear, though it may have a role in mating, found in oceans and seas around the world, humpback whales typically migrate up to 25,000 km each year. Humpbacks feed in polar waters, and migrate to tropical or subtropical waters to breed and give birth when they fast and their diet consists mostly of krill and small fish. Humpbacks have a repertoire of feeding methods, including the bubble net technique. Like other large whales, the humpback was a target for the whaling industry, once hunted to the brink of extinction, its population fell by an estimated 90% before a 1966 moratorium. While stocks have partially recovered, entanglement in fishing gear, collisions with ships, the rorquals are believed to have diverged from the other families of the suborder Mysticeti as long ago as the middle Miocene. However, it is not known when the members of these families diverged from each other, though clearly related to the giant whales of the genus Balaenoptera, the humpback is the sole member of its genus. The humpback was first identified as de la Nouvelle Angleterre by Mathurin Jacques Brisson in his Regnum Animale of 1756. In 1781, Georg Heinrich Borowski described the species, converting Brissons name to its Latin equivalent, in 1804, Lacépède shifted the humpback from the family Balaenidae, renaming it B. jubartes. In 1846, John Edward Gray created the genus Megaptera, classifying the humpback as Megaptera longipinna, the common name is derived from the curving of their backs when diving. The generic name Megaptera from the Greek mega-/μεγα- giant and ptera/πτερα wing, the specific name means New Englander and was probably given by Brisson due to regular sightings of humpbacks off the coast of New England. Some biologists believe that these should be regarded as separate subspecies, humpbacks can easily be identified by their stocky body, obvious hump, black dorsal coloring and elongated pectoral fins. The head and lower jaw are covered with knobs called tubercles, the fluked tail, which typically rises above the surface when diving, has wavy trailing edges. Humpbacks have 270 to 400 darkly colored baleen plates on each side of their mouths, the plates measure from 18 in in the front to about 3 ft in the back, behind the hinge. Ventral grooves run from the jaw to the umbilicus, about halfway along the underside of the body

Abel Tasman
–
Abel Janszoon Tasman was a Dutch seafarer, explorer, and merchant, best known for his voyages of 1642 and 1644 in the service of the Dutch East India Company. In 1633 he sailed from Texel to Batavia in the service of the Dutch East India Company, Tasman took part in a voyage to Seram Island, the locals had sold spices to others than the Dutch. He had a escape from death, when in an incautious landing several of his companions were killed by people of Seram. In August 1637 he was back in Amsterdam, and the year he signed on for another ten years. On 25 March 1638 he tried to sell his property in the Jordaan, in 1639 he was second-in-command of an exploration expedition in the north Pacific under Matthijs Quast. The fleet included the ships Engel and Gracht and reached Fort Zeelandia and this expedition used two small ships, the Heemskerck and the Zeehaen. According to Marco Polo, Locach was a kingdom where gold was “so plentiful that no one who did not see it could believe it”, Beach was in fact a mistranscription of Locach. Locach was Marco Polo’s name for the southern Thai kingdom of Lavo, or Lop Buri, in Chinese, Lavo was pronounced “Lo-huk”, from which Marco Polo took his rendition of the name. In the German cursive script, “Locach” and “Boeach” look similar and they seem to have drawn on the map of the world published in Florence in 1489 by Henricus Martellus, in which provincia boëach appears as the southern neighbour of provincia ciamba. Book III of Marco Polo’s Il Milione described his journey by sea from China to India by way of Champa, Java, Locach, after a chapter describing the kingdom of Champa there follows a chapter describing Java. Locach, located between Champa and Sumatra, was likewise misplaced far to the south of Java, by some geographers on or near an extension of the Terra Australis. Gerard Mercator did just that on his 1541 globe, placing Beach provincia aurifera in the northernmost part of the Terra Australis in accordance with the faulty text of Marco Polo’s Travels. Following Mercator, Abraham Ortelius also showed BEACH and LVCACH in these locations on his map of 1571. Confirmation that land existed where the maps showed Beach to be had come from Dirk Hartog’s landing in October 1616 on its west coast, which he called Eendrachtsland after the name of his ship. In accordance with Visschers directions, Tasman sailed from Batavia on 14 August 1642 and arrived at Mauritius on 5 September 1642, the reason for this was the crew could be fed well on the island, there was plenty of fresh water and timber to repair the ships. Tasman got the assistance of the governor Adriaan van der Stel, because of the prevailing winds Mauritius was chosen as a turning point. After a four-week stay on the island both ships left on 8 October using the Roaring Forties to sail east as fast as possible. On 7 November snow and hail influenced the ships council to alter course to a more north-eastern direction, on 24 November 1642 Abel Tasman reached and sighted the west coast of Tasmania, north of Macquarie Harbour

Zeeland
–
Zeeland is the westernmost province of the Netherlands. The province, located in the south-west of the country, consists of a number of islands and peninsulas and its area is about 2,930 square kilometres, of which almost 1,140 square kilometres is water, and it has a population of about 380,000. Large parts of Zeeland are below sea level, the last great flooding of the area was in 1953. Tourism is an important economic activity, in the summer, its beaches make it a popular destination for tourists, especially German tourists. In some areas, the population can be two to four times higher during the summer season. The coat of arms of Zeeland shows a lion half-emerged from water, the country of New Zealand is named after Zeeland - not Zealand in Denmark, as sometimes claimed. Nehalennia is a goddess of the ancient religion known around the province of Zeeland and her worship dates back at least to the 2nd century BC, and flourished in the 2nd and 3rd centuries AD. She was possibly a goddess, either Celtic or pre-Germanic – sources differ on the culture that first worshipped her. During the Roman Era, her main function appeared to be the protection of travelers, most of what is known about her comes from the remains of over 160 carved stone offerings which have been dredged up from the Eastern Scheldt since 1970. Two more Nehalennia offering stones have also found in Cologne. Zeeland was an area between the counts of Holland and Flanders until 1299, when the last count of Holland died. Followed by the counts of Bavaria, Burgundy and Habsburg, after 1585 Zeeland followed, as one of the 7 independent provinces, the fate of the Northern part of The Netherlands. In 1432 it became part of the Low Countries possessions of Philip the Good of Burgundy, through marriage, the Seventeen Provinces became the property of the Habsburgs in 1477. In the Eighty Years War, Zeeland was on the side of the Union of Utrecht, the area now called Zeeuws-Vlaanderen was not part of Zeeland, but a part of the county of Flanders that was conquered by the United Provinces, hence called Staats-Vlaanderen. After the French occupation and the formation of the United Kingdom of the Netherlands in 1815, during World War II, Zeeland was occupied by Nazi Germany between June 1940 and November 1944. In 1944, Zeeland was devastated by the Battle of the Scheldt, the catastrophic North Sea flood of 1953, which killed over 1800 people in Zeeland, led to the construction of the protective Delta Works. The province of Zeeland is a river delta situated at the mouth of several major rivers, namely Scheldt, Rhine. Most of the province lies below sea level and was reclaimed from the sea by inhabitants over time, what used to be a muddy landscape, flooding at high tide and reappearing at low tide, became a series of small man-made hills that stayed dry at all times

Netherlands
–
The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

James Cook
–
Captain James Cook FRS RN was a British explorer, navigator, cartographer, and captain in the Royal Navy. Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755 and he saw action in the Seven Years War, and subsequently surveyed and mapped much of the entrance to the Saint Lawrence River during the siege of Quebec. This helped bring Cook to the attention of the Admiralty and Royal Society, in three voyages Cook sailed thousands of miles across largely uncharted areas of the globe. He mapped lands from New Zealand to Hawaii in the Pacific Ocean in greater detail, as he progressed on his voyages of discovery he surveyed and named features, and recorded islands and coastlines on European maps for the first time. He displayed a combination of seamanship, superior surveying and cartographic skills, physical courage, Cook was attacked and killed while attempting to kidnap the native chief of Hawaii during his third exploratory voyage in the Pacific in 1779. He left a legacy of scientific and geographical knowledge which was to influence his successors well into the 20th century, and numerous memorials worldwide have been dedicated to him. James Cook was born on 7 November 1728 in the village of Marton in Yorkshire and baptised on 14 November in the church of St Cuthbert. He was the second of eight children of James Cook, a Scottish farm labourer from Ednam in Roxburghshire, in 1736, his family moved to Airey Holme farm at Great Ayton, where his fathers employer, Thomas Skottowe, paid for him to attend the local school. In 1741, after five years schooling, he work for his father. For leisure, he would climb a hill, Roseberry Topping, enjoying the opportunity for solitude. Cooks Cottage, his parents last home, which he is likely to have visited, is now in Melbourne, having moved from England and reassembled, brick by brick. In 1745, when he was 16, Cook moved 20 miles to the village of Staithes. Historians have speculated that this is where Cook first felt the lure of the sea while gazing out of the shop window. After 18 months, not proving suitable for work, Cook travelled to the nearby port town of Whitby to be introduced to friends of Sandersons, John. The Walkers, who were Quakers, were prominent local ship-owners in the coal trade and their house is now the Captain Cook Memorial Museum. Cook was taken on as a merchant navy apprentice in their fleet of vessels. His first assignment was aboard the collier Freelove, and he spent several years on this and various other coasters, sailing between the Tyne and London. As part of his apprenticeship, Cook applied himself to the study of algebra, geometry, trigonometry, navigation and his three-year apprenticeship completed, Cook began working on trading ships in the Baltic Sea

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

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
