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

Italy
–
Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, Italian culture flourished at this time, producing famous scholars, artists and polymaths such as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France, Spain and Austria. Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military, cultural and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

Italian Peninsula
–
The Italian Peninsula or Apennine Peninsula is the central and the smallest of the three large peninsulas of Southern Europe. It extends 1,000 km from the Po Valley in the north to the central Mediterranean Sea in the south, the peninsulas shape gives it the nickname lo Stivale. Three smaller peninsulas contribute to this shape, namely Calabria, Salento. Geographically, the Italian peninsula consists of the south of a line extending from the Magra to the Rubicon rivers. It excludes the Po Valley and the slopes of the Alps. All of the lies within the territory of the Italian Republic except for the microstates of San Marino. Additionally, Sicily, Elba and other islands, such as Palagruža, are usually considered as islands off the peninsula. The peninsula lies between the Tyrrhenian Sea on the west, the Ionian Sea on the south, and the Adriatic Sea on the east, the backbone of the Italian peninsula consists of the Apennine Mountains, from which it takes one of its names. Most of its coast is lined with cliffs, the Italian Peninsulas location between the centre of Europe and the Mediterranean Sea made it the target of many conquests. The peninsula has mainly a Mediterranean climate, though in the parts the climate is much cooler. Its natural vegetation includes macchia along the coasts and deciduous and mixed coniferous forests in the interior.

Alps
–
The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc, Mont Blanc spans the French–Italian border, and at 4,810 m is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres, the altitude and size of the range affects the climate in Europe, in the mountains precipitation levels vary greatly and climatic conditions consist of distinct zones. Wildlife such as live in the higher peaks to elevations of 3,400 m. Evidence of human habitation in the Alps goes back to the Palaeolithic era, a mummified man, determined to be 5,000 years old, was discovered on a glacier at the Austrian–Italian border in 1991. By the 6th century BC, the Celtic La Tène culture was well established, Hannibal famously crossed the Alps with a herd of elephants, and the Romans had settlements in the region. In 1800 Napoleon crossed one of the passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, in World War II, Adolf Hitler kept a base of operation in the Bavarian Alps throughout the war. The Alpine region has a cultural identity. The Winter Olympic Games have been hosted in the Swiss, French, at present, the region is home to 14 million people and has 120 million annual visitors. The English word Alps derives from the Latin Alpes, maurus Servius Honoratus, an ancient commentator of Virgil, says in his commentary that all high mountains are called Alpes by Celts. The term may be common to Italo-Celtic, because the Celtic languages have terms for high mountains derived from alp and this may be consistent with the theory that in Greek Alpes is a name of non-Indo-European origin. According to the Old English Dictionary, the Latin Alpes might possibly derive from a pre-Indo-European word *alb hill, Albania, a name not native to the region known as the country of Albania, has been used as a name for a number of mountainous areas across Europe. In Roman times, Albania was a name for the eastern Caucasus, in modern languages the term alp, alm, albe or alpe refers to a grazing pastures in the alpine regions below the glaciers, not the peaks. An alp refers to a mountain pasture where cows are taken to be grazed during the summer months and where hay barns can be found. The Alps are a crescent shaped geographic feature of central Europe that ranges in a 800 km arc from east to west and is 200 km in width, the mean height of the mountain peaks is 2.5 km. The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble, the range continues onward toward Vienna, Austria, and east to the Adriatic Sea and Slovenia. To the south it dips into northern Italy and to the north extends to the border of Bavaria in Germany

Po Valley
–
The Po Valley, Po Plain, Plain of the Po, or Padan Plain is a major geographical feature of Italy. The flatlands of Veneto and Friuli are often considered apart since they do not drain into the Po, the plain is the surface of an in-filled system of ancient canyons extending from the Apennines in the south to the Alps in the north, including the northern Adriatic. Geo-political definitions of the valley depend on the defining authority, the Po Basin Water Board, authorized in 1989 by Law no. The law defines the Po basin as the territory from which rainwater or snow and glacier melt flows on the surface, the valley is crossed by a number of affluents running down from the Alps in the north and from the Apennines in the south. The Pos major affluents include the Tanaro, Scrivia, Trebbia, Panaro and Secchia in the south, Dora Riparia, Dora Baltea, Sesia, Ticino, Lambro, Adda, Oglio and Mincio in the north. Since the Messinian the system has been filling with sediment mainly from the older Apennines, the shoreline of the Adriatic depends on a balance between the sedimentation rate and isostatic factors. Until about 1950 the Po delta was prograding into the Adriatic, where the land surface now dips below sea level the river must run at a relative elevation between dikes. The Po Valley is often regarded as a syncline, or dip in the crust due to compression at the edges. Regardless of whether this concept accurately describes its geology, the valley is manifestly a sediment-filled trough, or virtual syncline, the upper areas of the Po valley take local names which reflect in their meanings their being modestly suited for farming. It varies from a few kilometres to as much as 50 km wide, the fontanili line is the outcrop, or intersection, of the anticlines water table with the surface at the edge of the bassa. The rock above the line is porous, surface water in the intermittent streams of the mountains tends to disappear below ground only to spring out again in the spring zone. The spring zone is called the middle valley. Surface runoff water is not of value to the valleys dense population for drinking and other immediate uses, being unreliable, often destructive and heavily polluted by sewage. Its main anthropic value is for power, irrigation and industrial transport. The cost of purifying it for consumption makes that process less feasible. The fresh drinking water comes from hundreds of thousands of wells concentrated especially in the fontanili zone, the older and smaller cities deriving from ancient times are still located there. The Po Valley has a subtropical climate. The conformation of the plain, surrounded by the Alps and the Apennines, the climate of the Po Valley becomes increasingly warmer and more humid farther south and east

Sicily
–
Sicily is the largest island in the Mediterranean Sea. It is an autonomous Region of Italy, along with surrounding minor islands, Sicily is located in the central Mediterranean Sea, south of the Italian Peninsula, from which it is separated by the narrow Strait of Messina. Its most prominent landmark is Mount Etna, the tallest active volcano in Europe, the island has a typical Mediterranean climate. The earliest archaeological evidence of activity on the island dates from as early as 12,000 BC. It became part of Italy in 1860 following the Expedition of the Thousand, a revolt led by Giuseppe Garibaldi during the Italian unification, Sicily was given special status as an autonomous region after the Italian constitutional referendum of 1946. Sicily has a rich and unique culture, especially regard to the arts, music, literature, cuisine. It is also home to important archaeological and ancient sites, such as the Necropolis of Pantalica, the Valley of the Temples, Sicily has a roughly triangular shape, earning it the name Trinacria. To the east, it is separated from the Italian mainland by the Strait of Messina, about 3 km wide in the north, and about 16 km wide in the southern part. The northern and southern coasts are each about 280 km long measured as a line, while the eastern coast measures around 180 km. The total area of the island is 25,711 km2, the terrain of inland Sicily is mostly hilly and is intensively cultivated wherever possible. Along the northern coast, the ranges of Madonie,2,000 m, Nebrodi,1,800 m. The cone of Mount Etna dominates the eastern coast, in the southeast lie the lower Hyblaean Mountains,1,000 m. The mines of the Enna and Caltanissetta districts were part of a leading sulphur-producing area throughout the 19th century, Sicily and its surrounding small islands have some highly active volcanoes. Mount Etna is the largest active volcano in Europe and still casts black ash over the island with its ever-present eruptions and it currently stands 3,329 metres high, though this varies with summit eruptions, the mountain is 21 m lower now than it was in 1981. It is the highest mountain in Italy south of the Alps, Etna covers an area of 1,190 km2 with a basal circumference of 140 km. This makes it by far the largest of the three volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. In Greek Mythology, the deadly monster Typhon was trapped under the mountain by Zeus, Mount Etna is widely regarded as a cultural symbol and icon of Sicily. The Aeolian Islands in the Tyrrhenian Sea, to the northeast of mainland Sicily form a volcanic complex, the three volcanoes of Vulcano, Vulcanello and Lipari are also currently active, although the latter is usually dormant

Sardinia
–
Sardinia is the second largest island in the Mediterranean Sea and an autonomous region of Italy. It is located in the Western Mediterranean, just south of the French island of Corsica, the regions official name is Regione Autonoma della Sardegna / Regione Autònoma de Sardigna, and its capital and largest city is Cagliari. It is divided into four provinces and a metropolitan city and its indigenous language and the other minority languages spoken by the Sardinians enjoy equal dignity with Italian under regional law. The name Sardinia is from the pre-Roman noun *srd-, later romanised as sardus and it makes its first appearance on the Nora Stone, where the word Šrdn testifies to the names existence when the Phoenician merchants first arrived. According to Timaeus, one of Platos dialogues, Sardinia and its people as well might have named after Sardò. There has also been speculation that identifies the ancient Nuragic Sards with the Sherden, in Classical antiquity, Sardinia was called Ichnusa, Σανδάλιον Sandal, Sardinia and Sardó. Sardinia is the second-largest island in the Mediterranean Sea, with an area of 24,100 square kilometres and it is situated between 38°51 and 41°18 latitude north and 8°8 and 9°50 east longitude. To the west of Sardinia is the Sea of Sardinia, a unit of the Mediterranean Sea, to Sardinias east is the Tyrrhenian Sea, the nearest land masses are the island of Corsica, the Italian Peninsula, Sicily, Tunisia, the Balearic Islands, and Provence. The Tyrrhenian Sea portion of the Mediterranean Sea is directly to the east of Sardinia between the Sardinian east coast and the west coast of the Italian mainland peninsula, the Strait of Bonifacio is directly north of Sardinia and separates Sardinia from the French island of Corsica. The island has an ancient geoformation and, unlike Sicily and mainland Italy, is not earthquake-prone and its rocks date in fact from the Palaeozoic Era. Due to long erosion processes, the highlands, formed of granite, schist, trachyte, basalt, sandstone and dolomite limestone. The highest peak is Punta La Marmora, part of the Gennargentu Ranges in the centre of the island. The islands ranges and plateaux are separated by wide valleys and flatlands. Sardinia has few rivers, the largest being the Tirso,151 km long, which flows into the Sea of Sardinia, the Coghinas. There are 54 artificial lakes and dams that supply water and electricity, the main ones are Lake Omodeo and Lake Coghinas. The only natural lake is Lago di Baratz. A number of large, shallow, salt-water lagoons and pools are located along the 1,850 km of the coastline, the climate of the island is variable from area to area, due to several factors including the extension in latitude and the elevation. During the year there is a concentration of rainfall in the winter and autumn, some heavy showers in the spring

Corsica
–
Corsica is an island in the Mediterranean Sea and one of the 13 regions of France. It is located west of the Italian Peninsula, southeast of the French mainland, a single chain of mountains make up two-thirds of the island. While being part of France, Corsica is also designated as a territorial collectivity by law, as a territorial collectivity, Corsica enjoys a greater degree of autonomy than other French regions, for example, the Corsican Assembly is able to exercise limited executive powers. The island formed a single department until it was split in 1975 into two departments, Haute-Corse and Corse-du-Sud, with its capital in Ajaccio, the prefecture city of Corse-du-Sud. Bastia, the city of Haute-Corse, is the second-largest settlement in Corsica. After being ruled by the Republic of Genoa since 1284, Corsica was briefly an independent Corsican Republic from 1755 until it was conquered by France in 1769. Due to Corsicas historical ties with the Italian peninsula, the island retains to this day many elements of the culture of Italy, the native Corsican language, whose northern variant is closely related to the Italian language, is recognised as a regional language by the French government. This Mediterranean island was ruled by various nations over the course of history but had several periods of independence. Napoleon was born in 1769 in the Corsican capital of Ajaccio and his ancestral home, Maison Bonaparte, is today used as a museum. The origin of the name Corsica is subject to much debate, to the Ancient Greeks it was known as Kalliste, Corsis, Cyrnos, Cernealis, or Cirné. Of these Cyrnos, Cernealis, or Cirné derive from a corruption of the most ancient Greek name of the island, Σειρηνούσσαι, the claim that latter Greek names are based on the Phoenician word for peninsula are highly unlikely. Corsica has been occupied continuously since the Mesolithic era and it acquired an indigenous population that was influential in the Mediterranean during its long prehistory. The Romans, who built a colony in Aléria, considered Corsica as one of the most backward regions of the Roman world, the island produced sheep, honey, resin and wax, and exported many slaves, not well considered because of their fierce and rebellious character. Moreover, it was known for its wines, exported to Rome. Administratively, the island was divided in pagi, which in the Middle Ages became the pievi, Corsica was integrated by Emperor Diocletian in Roman Italy. In the 5th century, the half of the Roman Empire collapsed, and the island was invaded by the Vandals. Briefly recovered by the Byzantines, it became part of the Kingdom of the Lombards—this made it a dependency of the March of Tuscany. Pepin the Short, king of the Franks and Charlemagnes father, expelled the Lombards, in the first quarter of the 11th century, Pisa and Genoa together freed the island from the threat of Arab invasion
