Geography (from Ancient Greekγεωγραφίαgeōgraphía; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale.
Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize the discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography, remote sensing, interviews, and surveying. (Full article...)

The Count of Porto Alegre around age 61, c. 1865
Manuel Marques de Sousa, Count of Porto Alegre (13 June 1804 – 18 July 1875), nicknamed "the Gloved Centaur", was an army officer, politician and abolitionist of the Empire of Brazil. Born into a wealthy family of military background, Manuel Marques de Sousa joined the Portuguese Army in Brazil in 1817 when he was little more than a child. His military initiation occurred in the conquest of the Banda Oriental (Eastern Bank), which was annexed and became the southernmost Brazilian province of Cisplatina in 1821. For most of the 1820s, he was embroiled in the Brazilian effort to keep Cisplatina as part of its territory: first during the struggle for Brazilian independence and then in the Cisplatine War. It would ultimately prove a futile attempt, as Cisplatina successfully separated from Brazil to become the independent nation of Uruguay in 1828.
A few years later, in 1835 his native province of Rio Grande do Sul was engulfed in a secessionist rebellion, the Ragamuffin War. The conflict lasted for almost ten years, and the Count was leading military engagements for most of that time. He played a decisive role in saving the provincial capital from the Ragamuffin rebels, allowing forces loyal to the legitimate government to secure a key foothold. In 1852, he led a Brazilian division during the Platine War in an invasion of the Argentine Confederation that overthrew its dictator. He was awarded a noble title, eventually raised from baron to viscount and finally to count. (Full article...)
Before World War I, Armenians occupied a somewhat protected, but subordinate, place in Ottoman society. Large-scale massacres of Armenians had occurred in the 1890s and 1909. The Ottoman Empire suffered a series of military defeats and territorial losses—especially during the 1912–1913 Balkan Wars—leading to fear among CUP leaders that the Armenians would seek independence. During their invasion of Russian and Persian territory in 1914, Ottoman paramilitaries massacred local Armenians. Ottoman leaders took isolated instances of Armenian resistance as evidence of a widespread rebellion, though no such rebellion existed. Mass deportation was intended to permanently forestall the possibility of Armenian autonomy or independence. (Full article...)

T7's sister ship, T3. The only significant external difference was that T7 had two funnels.
Following Austria-Hungary's defeat in 1918, 96 was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which later became the Royal Yugoslav Navy, and was renamed T7. At the time, she and the seven other 250t-class boats were the only modern sea-going vessels of the fledgling maritime force. During the interwar period, T7 and the rest of the navy were involved in training exercises and cruises to friendly ports, but activity was limited by reduced naval budgets. The boat was captured by the Italians during the German-led Axisinvasion of Yugoslavia in April 1941. After her main armament was modernised, she served with the Royal Italian Navy under her Yugoslav designation, conducting coastal and second-line escort duties in the Adriatic Sea. Following the Italian capitulation in September 1943, she was handed over by the Germans to the Navy of the Independent State of Croatia. While sailing to Rijeka for a refit, she was attacked and driven aground by British Royal Navy small high-speed craft in June 1944 and then destroyed by the British Army to prevent her salvage. She was broken up in situ in 1953. (Full article...)

The ruins of Palmyra in 2010
Palmyra (/pælˈmaɪrə/pal-MY-rə; Palmyrene: 𐡶𐡣𐡬𐡥𐡴 (), romanized: Tadmor; Arabic: تَدْمُر, romanized: Tadmur) is an ancient city in the eastern part of the Levant, now in the center of modern Syria. Archaeological finds date back to the Neolithic period, and documents first mention the city in the early second millennium BC. Palmyra changed hands on a number of occasions between different empires before becoming a subject of the Roman Empire in the first century AD. (Full article...)
Powder House Island was the location of dynamite storage sheds, as well as a dynamite factory and several ice houses. During this time, it was the site of a series of accidents, including fires in 1895 and 1919 (which both burned the island "to the water's edge"). Twenty short tons (18,000 kg) of the island's dynamite exploded in 1906 after two men "had been shooting with a revolver" near it; while there were no deaths (and only minor injuries to the two men), windows were shattered 3 mi (4.8 km) away and the explosion was clearly audible from 85 mi (137 km) away.

The Arctic tern (Sterna paradisaea) is a tern in the familyLaridae. This bird has a circumpolar breeding distribution covering the Arctic and sub-Arctic regions of Europe (as far south as Brittany), Asia, and North America (as far south as Massachusetts). The species is strongly migratory, seeing two summers each year as it migrates along a convoluted route from its northern breeding grounds to the Antarctic coast for the southern summer and back again about six months later. Recent studies have shown average annual round-trip lengths of about 70,900 km (44,100 mi) for birds nesting in Iceland and Greenland and about 48,700 km (30,300 mi) for birds nesting in the Netherlands. These are by far the longest migrations known in the animal kingdom. The Arctic tern nests once every one to three years (depending on its mating cycle).
Arctic terns are medium-sized birds. They have a length of 28–39 cm (11–15 in) and a wingspan of 65–75 cm (26–30 in). They are mainly grey and white plumaged, with a red/orange beak and feet, white forehead, a black nape and crown (streaked white), and white cheeks. The grey mantle is 305 mm (12.0 in), and the scapulae are fringed brown, some tipped white. The upper wing is grey with a white leading edge, and the collar is completely white, as is the rump. The deeply forked tail is whitish, with grey outer webs. (Full article...)

Joppenbergh Mountain, viewed from across the Rondout Creek
Joppenbergh Mountain is a nearly 500-foot (152 m) mountain in Rosendale Village, a hamlet in the town of Rosendale, in Ulster County, New York. The mountain is composed of a carbonatebedrock overlain by glacially deposited material. It was named after Rosendale's founder, Jacob Rutsen, and mined throughout the late 19th century for dolomite that was used in the manufacture of natural cement. Extensive mining caused a large cave-in on December 19, 1899, that destroyed equipment and collapsed shafts within Joppenbergh. Though it was feared that several workers had been killed, the collapse happened while all the miners were outside, eating lunch. Since the collapse, the mountain has experienced shaking and periodic rockfalls.
During the late 1930s, Joppenbergh became the site of several ski jumping competitions, which continued until the early 1940s. The original slope was designed by Harold Schelderup for Rosendale's first competition in 1937; Schelderup himself skied that July, after the slope was coated with borax for a summer competition. Several Olympic skiers participated in the competitions. Skiing began again in the 1960s, when a new slope was built on the mountain, and the revived competitions continued until 1971.

Glacier National Park is a national park of the United States located in northwestern Montana, on the Canada–United States border. The park encompasses more than 1 million acres (4,100 km2) and includes parts of two mountain ranges (sub-ranges of the Rocky Mountains), more than 130 named lakes, more than 1,000 different species of plants, and hundreds of species of animals. This vast pristine ecosystem is the centerpiece of what has been referred to as the "Crown of the Continent Ecosystem", a region of protected land encompassing 16,000 sq mi (41,000 km2).
The region that became Glacier National Park was first inhabited by Native Americans. Upon the arrival of European explorers, it was dominated by the Blackfeet in the east and the Flathead in the western regions. Under pressure, the Blackfeet ceded the mountainous parts of their treaty lands in 1895 to the federal government; it later became part of the park. Soon after the establishment of the park on May 11, 1910, a number of hotels and chalets were constructed by the Great Northern Railway. These historic hotels and chalets are listed as National Historic Landmarks and a total of 350 locations are on the National Register of Historic Places. By 1932 work was completed on the Going-to-the-Sun Road, later designated a National Historic Civil Engineering Landmark, which provided motorists easier access to the heart of the park.

Robert Marshall (January 2, 1901 – November 11, 1939) was an American forester, writer and wilderness activist who is best remembered as the person who spearheaded the 1935 founding of the Wilderness Society in the United States. Marshall developed a love for the outdoors as a young child. He was an avid hiker and climber who visited the Adirondack Mountains frequently during his youth, ultimately becoming one of the first Adirondack Forty-Sixers. He also traveled to the Brooks Range of the far northern Alaskan wilderness. He wrote numerous articles and books about his travels, including the bestselling 1933 book Arctic Village.
A scientist with a PhD in plant physiology, Marshall became independently wealthy after the death of his father in 1929. He had started his outdoor career in 1925 as forester with the U.S. Forest Service. He used his financial independence for expeditions to Alaska and other wilderness areas. Later he held two significant public appointed posts: chief of forestry in the Bureau of Indian Affairs, from 1933 to 1937, and head of recreation management in the Forest Service, from 1937 to 1939, both during the administration of President Franklin D. Roosevelt. During this period, he directed the promulgation of regulations to preserve large areas of roadless land that were under federal management. Many years after his death, some of those areas were permanently protected from development, exploitation, and mechanization with the passage of the Wilderness Act of 1964. (Full article...)
During the 1850s and again after his participation in the Civil War, Raynolds was the head engineer on numerous lighthouse construction projects. He oversaw riverway and harbor dredging projects intended to improve accessibility and navigation for shipping. As a cartographer, Raynolds surveyed and mapped the islands and shorelines on the Great Lakes and other regions. At least six lighthouses whose construction he oversaw are still standing. Some are still in use and of these, several are listed on the National Register of Historic Places. (Full article...)
The city lies in the traditional territory of the Stillaguamish people, an indigenous Coast Salish group. Arlington was established in the 1880s by settlers and the area was platted as two towns, Arlington and Haller City. Haller City was absorbed by the larger Arlington, which was incorporated as a city in 1903. During the Great Depression of the 1930s, the Arlington area was the site of major projects undertaken for employment under the direction of federal relief agencies, including construction of a municipal airport that would serve as a naval air station during World War II. Arlington began suburbanizing in the 1980s, growing by more than 450 percent by 2000 and annexing the unincorporated area of Smokey Point to the southwest. (Full article...)
The Columbia Slough is a narrow waterway, about 19 miles (31 km) long, in the floodplain of the Columbia River in the U.S. state of Oregon. From its source in the Portland suburb of Fairview, the Columbia Slough meanders west through Gresham and Portland to the Willamette River, about 1 mile (1.6 km) from the Willamette's confluence with the Columbia. It is a remnant of the historic wetlands between the mouths of the Sandy River to the east and the Willamette River to the west. Levees surround much of the main slough as well as many side sloughs, detached sloughs, and nearby lakes. Drainage district employees control water flows with pumps and floodgates. Tidal fluctuations cause reverse flow on the lower slough.
The Columbia floodplain, formed by geologic processes including lava flows, volcanic eruptions, and the Missoula Floods, is part of the Portland Basin, which extends across the Columbia River from Multnomah County, Oregon, into Clark County, Washington. Five percent of Oregon's population, about 158,000 people, live in the slough watershed of about 51 square miles (130 km2). Municipal wells near the upper slough provide supplemental drinking water to Portland and nearby cities. The cities, the drainage districts, the county, and a regional government, Metro, have overlapping jurisdictions in the watershed. A regional agency operates Portland International Airport along the middle slough and marine terminals near the lower slough. The Oregon Department of Environmental Quality (DEQ) and the city's Bureau of Environmental Services (BES) deal with environmental issues. (Full article...)

Interior of the former vegetable market, 2006
Covent Garden is a district in London, on the eastern fringes of the West End, between St Martin's Lane and Drury Lane. It is associated with the former fruit-and-vegetable market in the central square, now a popular shopping and tourist site, and with the Royal Opera House, itself known as "Covent Garden". The district is divided by the main thoroughfare of Long Acre, north of which is given over to independent shops centred on Neal's Yard and Seven Dials, while the south contains the central square with its street performers and most of the historical buildings, theatres and entertainment facilities, including the London Transport Museum and the Theatre Royal, Drury Lane.
The area was fields until briefly settled in the 7th century when it became the heart of the Anglo-Saxon trading town of Lundenwic, then abandoned at the end of the 9th century after which it returned to fields. By 1200 part of it had been walled off by the Abbot of Westminster Abbey for use as arable land and orchards, later referred to as "the garden of the Abbey and Convent", and later "the Convent Garden". Following the Dissolution of the Monasteries it was granted in 1552 by the young King Edward VI to John Russell, 1st Earl of Bedford (c.1485–1555), the trusted adviser to his father King Henry VIII. The 4th Earl commissioned Inigo Jones to build some fine houses to attract wealthy tenants. Jones designed the Italianate arcaded square along with the church of St Paul's. The design of the square was new to London and had a significant influence on modern town planning, acting as the prototype for new estates as London grew. (Full article...)
The Rashtrakutas were a royal Indian dynasty ruling large parts of the Indian subcontinent between the 6th and 10th centuries. The earliest known Rashtrakuta inscription is a 7th-century copper plate grant detailing their rule from Manapur, a city in Central or West India. Other ruling Rashtrakuta clans from the same period mentioned in inscriptions were the kings of Achalapur and the rulers of Kannauj. Several controversies exist regarding the origin of these early Rashtrakutas, their native homeland and their language.
The Elichpur clan was a feudatory of the Badami Chalukyas, and during the rule of Dantidurga, it overthrew Chalukya Kirtivarman II and went on to build an empire with the Gulbarga region in modern Karnataka as its base. This clan came to be known as the Rashtrakutas of Manyakheta, rising to power in South India in 753 AD. At the same time the Pala dynasty of Bengal and the Prathihara dynasty of Gurjaratra were gaining force in eastern and northwestern India respectively. An Arabic text, Silsilat al-Tawarikh (851), called the Rashtrakutas one of the four principal empires of the world. (Full article...)

View of bog and lake from the bog trail in the Black Moshannon Bog Natural Area at Black Moshannon State Park
Humans have long used the Black Moshannon area for recreational, industrial, and subsistence purposes. The Seneca tribe used it as hunting and fishing grounds. European settlers cleared some land for farming, then clear-cut the vast stands of old-growth white pine and eastern hemlock. Black Moshannon State Park rose from the ashes of a depleted forest which had been largely destroyed by wildfire in the years following the lumber era. The forests were rehabilitated by the Civilian Conservation Corps during the Great Depression in the 1930s. Many of the buildings built by the Civilian Conservation Corps stand in the park today and are protected on the list of National Register of Historic Places in three historic districts.

Map: Strebe, using the Geocart map projection software
A two-point equidistant projection of Eurasia. All distances of other points from the two points marked in red (45°N 40°E and 30°N 110°E) are correct. This map is a derivative of NASA's Blue Marble summer month composite, with oceans lightened to enhance legibility and contrast.
The Robinson projection is a projection of a world map showing the entire Earth at once. It was specifically created in an attempt to find a good compromise to the problem of showing the whole globe as a single flat image. The projection was devised by Arthur H. Robinson in 1963; distortion is severe close to the poles, but quickly declines to moderate levels as latitudes decrease. This Robinson-projection map, with standard parallels of 38°N and 38°S, was produced by the United States Central Intelligence Agency and shows the world as of February 2016.
Illustration of the Ptolemaicgeocentric model of the Universe (the theory that the Earth is the center of the universe) by Portuguese cosmographer and cartographer Bartolomeu Velho. Taken from his treatise Cosmographia, made in Paris, 1568. Notice the distances of the bodies to the centre of the Earth (left) and the times of revolution, in years (right).
A portolan chart from 1492, the oldest known signed and dated chart of Portuguese origin. Cartography technologies greatly advanced during the Age of Discovery. Iberian mapmakers in particular focused on practical charts to use as navigational aids. Unlike Spanish maps which were regarded as state secrets, Portuguese ones were used by other countries, and Portuguese cartographers drew upon the skill and knowledge of other cultures as well.
The General Perspective projection is a map projection used in cartography in which the Earth is depicted as viewed from a finite distance above its surface. If the view precisely faces the center of the Earth, the projection is a vertical perspective projection; otherwise, it is a tilted perspective projection. Here is shown a vertical perspective from an altitude of 35,786 km over (0°, 90°W), corresponding to a view from geostationary orbit. Due to the horizon as seen from the viewpoint position, the projection always shows less than half of the Earth's surface: in this case neither of the North and South Poles is visible.
The Mollweide projection is an equal-area, pseudocylindrical map projection generally used for global maps of the world or night sky. The projection was first published by mathematician and astronomer Karl Mollweide of Leipzig in 1805 but reinvented and popularized in 1857 by Jacques Babinet. The projection trades accuracy of angle and shape for accuracy of proportions in area, and as such is used where that property is needed, such as maps depicting global distributions.
A detailed eighteenth-century map of Scandinavia by J. B. Homann, depicting Denmark, Norway, Sweden, Finland and the Baltic states of Livonia, Latvia and Curlandia. The map notes fortified cities, villages, roads, bridges, forests, castles and topography. The elaborate title cartouche in the upper left quadrant features angels supporting a title curtain and a medallion supporting an alternative title in French, "Les Trois Covronnes du Nord".
Born in 1664, Homann became an engraver and cartographer in the late 17th century, and opened his own publishing house in 1702. In 1715 Emperor Charles VI appointed him Imperial Geographer of the Holy Roman Empire. Homann held the position until his death in 1724.
The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. Because it represents paths of constant course as straight lines, it long served as the standard map projection for nautical purposes. However, it distorts the size of objects as the latitude increases: thus areas in the mid-latitudes appear significantly larger than their actual size relative to those the equator, and those near the poles are even more exaggerated. Most modern atlases no longer use the Mercator projection for world maps or for areas distant from the equator, preferring other cylindrical projections, or forms of equal-area projection.
This picture is a panoramic map of North Cascades National Park, as viewed from the east, created in 1987 by Austrian painter and cartographer Heinrich C. Berann for the National Park Service.
A c. 1650 map showing the Island of California, a long-held European misconception, dating from the 16th century, that California was not part of mainland North America but rather a large island separated from the continent by a strait now known instead as the Gulf of California.

The mark of Pierre Rossier's photographic studio in Fribourg
Pierre Joseph Rossier (16 July 1829 – 22 October 1886) was a pioneering Swiss photographer whose albumen photographs, which include stereographs and cartes-de-visite, comprise portraits, cityscapes, and landscapes. He was commissioned by the London firm of Negretti and Zambra to travel to Asia and document the progress of the Anglo-French troops in the Second Opium War and, although he failed to join that military expedition, he remained in Asia for several years, producing the first commercial photographs of China, the Philippines, Japan and Siam (now Thailand). He was the first professional photographer in Japan, where he trained Ueno Hikoma, Maeda Genzō, Horie Kuwajirō, as well as lesser known members of the first generation of Japanese photographers. In Switzerland he established photographic studios in Fribourg and Einsiedeln, and he also produced images elsewhere in the country. Rossier is an important figure in the early history of photography not only because of his own images, but also because of the critical impact of his teaching in the early days of Japanese photography.

A map of the United States showing its 50 states, federal district and five inhabited territories. Alaska, Hawaii, and the territories are shown at different scales, and the Aleutian Islands and the uninhabited northwestern Hawaiian Islands are omitted from the map. The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. Both the states and the United States as a whole are each sovereign jurisdictions. The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government, and all states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state elects two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states.

It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular landmarks. It has many types of ecosystems, but the subalpine forest is the most abundant. The park is part of the South Central Rockies forests ecoregion. In 1978, Yellowstone was named a World Heritage Site by UNESCO.

At more than 500,000 acres (200,000 ha), North Cascades National Park is the largest of the three National Park Service units that comprise the North Cascades National Park Complex. North Cascades National Park consists of a northern and southern section, bisected by the Skagit River that flows through Ross Lake National Recreation Area. Lake Chelan National Recreation Area lies on the southern border of the south unit of the park. In addition to the two national recreation areas, other protected lands including several national forests and wilderness areas, as well as Canadian provincial parks in British Columbia, nearly surround the park. North Cascades National Park features the rugged mountain peaks of the North Cascades Range, the most expansive glacial system in the contiguous United States, the headwaters of numerous waterways, and vast forests with the highest degree of flora biodiversity of any American national park.

A satellite image of the Sahara, the world's largest hot desert and second largest desert after Antarctica at over 9,000,000 km² (3,500,000 mi²), almost as large as the United States. The Sahara is located in Northern Africa and is 2.5 million years old.
Map: Strebe, using GeocartThe Eckert II projection is an equal-area pseudocylindrical map projection presented by Max Eckert-Greifendorff in 1906. In the equatorial aspect (where the equator is shown as the horizontal axis) the network of longitude and latitude lines consists solely of straight lines, and the outer boundary has the distinctive shape of an elongated hexagon.
Map: Strebe, using GeocartA gnomonic projection of a portion of the northern hemisphere, centered on the geographic North Pole. Such projections display all great circles as straight lines, resulting in any line segment on a gnomonic map showing the shortest route between the segment's two endpoints.
