Björn Gunnlaugsson
Björn Gunnlaugsson (25 September 1788 – 17 March 1876)Benedikz, p. 568ff. was an Icelandic mathematician and cartographer. For the Icelandic Literary Society, he surveyed the country from 1831 to 1843. The results of his work were published in a topographic map of Iceland at a scale of 1:480,000 on four sheets.Sævarsson. It was the first complete map of Iceland and, although generally dated to 1844, was not completed until 1848. It was published under the direction of Olaf Nikolas Olsen in Copenhagen. In 1849, a smaller edition on one sheet at a scale of 1:960,000 appeared. For his survey work, Björn received the Order of the Dannebrog in 1846 and the French Légion d'honneur in 1859.Þorvaldur Thoroddsen, p. 317. Life Björn was born at Tannstaðir, a remote farm on the Hrútafjörður in Húnavatnssýsla in north-western Iceland. Although the family was poor, they sent him to school to the local priests, who recognized his intellectual abilities. In 1808, Bjö ...

Order (decoration)
An order is a visible honour awarded by a sovereign state, monarch, dynastic house or organisation to a person, typically in recognition of individual merit, that often comes with distinctive insignia such as collars, medals, badges, and sashes worn by recipients. Modern honour systems of state orders and dynastic orders emerged from the culture of orders of chivalry of the Middle Ages, which in turn emerged from the Catholic religious orders. Terminology The word order ( la, ordo), in the case referred to in this article, can be traced back to the chivalric orders, including the military orders, which in turn trace the name of their organisation back to that of the Catholic religious orders. Orders began to be created ''ad hoc'' and in a more courtly nature. Some were merely honorary and gradually the ''badges'' of these orders (i.e. the association) began to be known informally as ''orders''. As a result, the modern distinction between ''orders'' and ''decorations'' or ''ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napoleonic Wars
The Napoleonic Wars (1803–1815) were a series of major global conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European states formed into various coalitions. It produced a period of French domination over most of continental Europe. The wars stemmed from the unresolved disputes associated with the French Revolution and the French Revolutionary Wars consisting of the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). The Napoleonic Wars are often described as five conflicts, each termed after the coalition that fought Napoleon: the Third Coalition (1803–1806), the Fourth (1806–1807), the Fifth (1809), the Sixth (1813–1814), and the Seventh (1815) plus the Peninsular War (1807–1814) and the French invasion of Russia (1812). Napoleon, upon ascending to First Consul of France in 1799, had inherited a republic in chaos; he subsequently created a state with stable financ ...

Island218d
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. ...

Conical Projection
In cartography, map projection is the term used to describe a broad set of transformations employed to represent the two-dimensional curved surface of a globe on a plane. In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. Projection is a necessary step in creating a two-dimensional map and is one of the essential elements of cartography. All projections of a sphere on a plane necessarily distort the surface in some way and to some extent. Depending on the purpose of the map, some distortions are acceptable and others are not; therefore, different map projections exist in order to preserve some properties of the sphere-like body at the expense of other properties. The study of map projections is primarily about the characterization of their distortions. There is no limit to the number of possible map projections. More generally, projections are considered in seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triangulation
In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to the point from known points. Applications In surveying Specifically in surveying, triangulation involves only angle measurements at known points, rather than measuring distances to the point directly as in trilateration; the use of both angles and distance measurements is referred to as triangulateration. In computer vision Computer stereo vision and optical 3D measuring systems use this principle to determine the spatial dimensions and the geometry of an item. Basically, the configuration consists of two sensors observing the item. One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector. The projection centers of the sensors and the considered point on the object's surface define a (spatial) triangle. Within this triangle, the distance between the sensors is the base ''b'' and must be known. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baseline (surveying)
In surveying, a baseline is a line between two points on the earth's surface and the direction and distance between them. In a triangulation network, at least one baseline between two stations needs to be measured to calculate the size of the triangles by trigonometry. In the United States Public Land Survey System, a baseline is the principal east-west line (i.e., a parallel) upon which all rectangular surveys in a defined area are based. The baseline meets its corresponding principal meridian at the point of origin, or '' initial point'', for the land survey. For example, the baseline for Nebraska and Kansas is shared as the border for both states, at the 40th parallel north. More specifically a baseline may be the line that divides a survey township between north and south. "Baseline Road" in the United States Many communities in the United States have roads that run along survey baselines, many of which are named to reflect that fact. Some examples: * In Little Rock, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danish Navy
The Royal Danish Navy ( da, Søværnet) is the sea-based branch of the Danish Defence force. The RDN is mainly responsible for maritime defence and maintaining the sovereignty of Danish territorial waters (incl. Faroe Islands and Greenland). Other tasks include surveillance, search and rescue, icebreaking, oil spill recovery and prevention as well as contributions to international tasks and forces. During the period 1509–1814, when Denmark was in a union with Norway, the Danish Navy was part of the Dano-Norwegian Navy. Until the copenhagenization of the navy in 1801, and again in 1807, the navy was a major strategic influence in the European geographical area, but since then its size and influence has drastically declined with a change in government policy. Despite this, the navy is now equipped with a number of large state-of-the-art vessels commissioned since the end of the Cold War. This can be explained by its strategic location as the NATO member controlling access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altona, Hamburg
Altona (), also called Hamburg-Altona, is the westernmost urban borough (''Bezirk'') of the German city state of Hamburg, on the right bank of the Elbe river. From 1640 to 1864, Altona was under the administration of the Danish monarchy. Altona was an independent borough until 1937. In 2016 the population was 270,263. History Altona was founded in 1535 as a village of fishermen in what was then Holstein-Pinneberg. In 1640, Altona came under Danish rule as part of Holstein-Glückstadt, and in 1664 was granted municipal rights by the Danish King Frederik III, who then ruled in personal union as Duke of Holstein. Altona was one of the Danish monarchy's most important harbor towns. The railroad from Altona to Kiel, the Hamburg-Altona–Kiel railway ( da, link=no, Christian VIII Østersø Jernbane), was opened in 1844. Because of severe restrictions on the number of Jews allowed to live in Hamburg until 1864 (with the exception of 1811–1815), a major Jewish community develop ...

Heinrich Christian Schumacher
Prof Heinrich Christian Schumacher FRS(For) FRSE (3 September 1780 – 28 December 1850) was a German-Danish astronomer and mathematician. Biography Schumacher was born at Bramstedt, in Holstein, near the German/Danish border. He was educated at Altona Gymnasium on the outskirts of Hamburg. He studied in Germany at Kiel, Jena, and Göttingen Universities as well as Copenhagen. He received a doctorate from Dorpat University in Russian Empire in 1807. From 1808, he was adjunct professor of astronomy in Copenhagen. He directed the Mannheim observatory from 1813 to 1815, and then in 1815 was appointed Professor of Astronomy in Copenhagen and Director of the Observatory. From 1817 he directed the triangulation of Holstein, to which a few years later was added a complete geodetic survey of Denmark (finished after his death). For the sake of the survey, Schumacher established the Altona Observatory at Altona, and resided there permanently. He was elected a Foreign Fellow of the ...

Bessastaðir
Bessastaðir () is the official residence of the president of Iceland. It is situated in Álftanes, about from the capital city, Reykjavík. History Bessastaðir was first settled in 1000. It became one of Snorri Sturluson's farms in the 13th century. After Snorri's murder in September 1241, Bessastaðir was claimed by the King of Norway. Thereafter it became a Royal stronghold and the dwellings of the King's highest-ranking officers and officials in Iceland. It resisted an attack by Turkish slave raiders in July 1627. In the late 18th century Bessastaðir was changed into a school for a few years, before becoming a farm. In 1867 the farm was purchased by the poet and statesman Grímur Thomsen, who lived there for almost two decades. Among later owners were editor and parliamentarian Skúli Thoroddsen, and his wife, Theodóra Thoroddsen Theodóra Friðrika Guðmundsdóttir Thoroddsen (1 July 1863 – 23 February 1954) was an Icelandic poet, folktale collector, translator, an ...

Menntaskólinn í Reykjavík
Menntaskólinn í Reykjavík (MR; official name in English: Reykjavik Junior College) is a junior college in Iceland. It is located in Reykjavík. The school traces its origin to 1056, when a school was established in Skálholt, and it remains one of the oldest institutions in Iceland. The school was moved to Reykjavík in 1786, but poor housing conditions forced it to move again in 1805 to Bessastaðir near Reykjavík. In 1846 the school was moved to its current location, and a new building was erected for it in Reykjavík. This was the largest building in the country at the time and can be seen on the 500 Icelandic krona bill. It was used initially when Althing began to meet again in Reykjavík after a few years hiatus and thus it is in this building where Icelandic independence leader Jón Sigurðsson led the MPs in their famous phrase, '' Vér mótmælum allir''. The school has previously been known as ''Lærði skólinn'' (The Learned School), ''Latínuskólinn'' (The Latin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
