Decauville Railway At Diégo Suarez
The Diego Suarez Decauville railway was a long gauge military railway from Antsiranana, Antsirane to Sakaramy in Madagascar. Construction and route The gauge Decauville railway was built in 1900 from Antsirane (now Antsiranana) to the Tunisian Fountain (''Fontaine Tunisienne'') at today's STAR factory. It started at the port and ran on the ''Rue Gouraud'' and the ''Boulevard Bazeilles'' up to the ''Cercle Français'' (now ''Suarez Art'') and up the ''Boulevard Militaire''. It turned into the ''Boulevard de Sakaramy'' at the height of ''Camp Lubert'', from where it led past the present town hall to ''l'Octroi'' and the Tunisian Fountain. At the end of 1900, it was extended from the Tunisian Fountain via Antanamitara and Andranomanitra to the junction of today's road to Joffreville. The route was designed by Captain Brunet to generally follow the terrain and thus to avoid large earthworks. At the Gorge of Antanamitara, a curve with a radius of only was needed. A deep cut a ...

Antsiranana
Antsiranana ( ), named Diego-Suarez prior to 1975, is a city in the far north of Madagascar. Antsiranana is the capital of Diana Region. It had an estimated population of 115,015 in 2013. History At the beginning of the 16th century, a Portuguese squadron of 13 ships crisscrossed the Indian Ocean; One of these ships went adrift, and its captain, Diogo Dias, was therefore the first European to discover the island on August 10, 1500, which he named Isle of Saint Lawrence. In February 1506, Admiral Fernão Soares recognized the place and so Antomabokala, former capital of Ankarana, acquired its name of Diego Suarez (Diogo Soares, in Portuguese), which comes from the junction of the first name of the captain and the surname of the Admiral. In 1635, the bay was mentioned for the first time under this name by the French pilot Berthelot, author of an oriental map of Africa and Madagascar. In 1824, the bay was explored by the English hydrographer Owen, then in 1833, Captain Bigeault, com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decauville Railway Diego Suarez – Le Camp D’Ambre At Camp Lubert And Boulevard Sakaramy
Decauville () was a manufacturing company which was founded by Paul Decauville (1846–1922), a French pioneer in industrial railways. Decauville's major innovation was the use of ready-made sections of light, narrow-gauge track fastened to steel sleepers; this track was portable and could be disassembled and transported very easily. The first Decauville railway used gauge; Decauville later refined his invention and switched to and gauge. History Origins In 1853 Paul Decauville's father, Amand, created a boilermaking workshop on the family farm in order to set up distilleries on the farms to the east of Paris. In 1864, Amand asked his eldest son, Paul, to come and help him following health problems. Very quickly, the latter seeks to improve the functioning of the estate. Very developed under the Second Empire in the northern half of France, the production of sugar beet and its refining into sugar, is linked to that of alcoholic products such as fuel. Amand will therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Buildings And Structures In Madagascar
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until th ...

600 Mm Gauge Railways
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics A six-sided polygon is a hexagon, one of the three regular polygons capable of tessellation, tiling the plane. A hexagon also has 6 Edge (geometry), edges as well as 6 internal and external angles. 6 is the second smallest composite number. It is also the first number that is the sum of its proper divisors, making it the smallest perfect number. It is also the only perfect number that doesn't have a digital root of 1. 6 is the first unitary perfect number, since it is the sum of its positive proper unitary divisors, without including itself. Only five such numbers are known to exist. 6 is the largest of the four Harshad number, all-Harshad numbers. 6 is the 2nd superior highly composite number, the 2nd colossally abundant number, the 3rd triangular number, the 4th highly composite number, a pronic number, a congruent number, a harmonic divisor nu ...

Tram Transport
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than Main line (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city stre ...

Narrow-gauge Railways In Madagascar
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge (distance between the rails) narrower than . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails; they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard: Japan, Indonesia, Taiwan, New Zealand, South ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exposition Universelle (1889)
The of 1889 (), better known in English as the 1889 Paris Exposition, was a world's fair held in Paris, France, from 6 May to 31 October 1889. It was the fifth of ten major expositions held in the city between 1855 and 1937. It attracted more than thirty-two million visitors. The most famous structure created for the exposition, and still remaining, is the Eiffel Tower. Organization The exposition was held to celebrate the 100th anniversary of the Storming of the Bastille, which marked the beginning of French Revolution, and was also seen as a way to stimulate the economy and pull France out of an economic recession. The exposition attracted 61,722 official exhibitors, of whom twenty-five thousand were from outside of France. Admission price Admission to the exposition cost forty centimes, at a time when the price of an "economy" plate of meat and vegetables in a Paris cafe was ten centimes. Visitors paid an additional price for several of the exposition's most popular att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diego Suarez - Chemin De Fer D'Antsirane Au Cap D'Ambre (cropped)
Diego is a Spanish masculine given name. The Portuguese equivalent is Diogo. The etymology of Diego is disputed, with two major origin hypotheses: ''Tiago'' and ''Didacus''. The name also has several patronymic derivations, listed below. Etymology ''Tiago'' hypothesis Diego has long been interpreted as variant of ''Tiago'' (also spelled as '' Thiago''), an abbreviation of ''Santiago'', from the older ''Sant Yago'' "Saint Jacob", in English known as Saint James or as ''San-Tiago'' (cf. ''San Diego''). This has been the standard interpretation of the name since at least the 19th century, as it was reported by Robert Southey in 1808 and by Apolinar Rato y Hevia (1891). The suggestion that this identification may be a folk etymology, i.e. that ''Diego'' (and ''Didacus''; see below) may be of another origin and only later identified with ''Jacobo'', is made by Buchholtz (1894), though this possibility is judged as improbable by the author. ''Didacus'' hypothesis In the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shuttle Radar Topography Mission
The Shuttle Radar Topography Mission (SRTM) is an international research effort that obtained digital elevation models on a near-global scale from 56th parallel south, 56°S to 60th parallel north, 60°N, to generate the most complete high-resolution digital topographic database of Earth prior to the release of the ASTER GDEM in 2009. SRTM consisted of a specially modified radar system that flew on board the Space Shuttle Endeavour during the 11-day STS-99 mission in February 2000. The radar system was based on the older ''Spaceborne Imaging Radar, Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar'' (SIR-C/X-SAR), previously used on the Shuttle in 1994. To acquire Topography, topographic data, the SRTM payload was outfitted with two radar antennas. One antenna was located in the Shuttle's payload bay, the other – a critical change from the SIR-C/X-SAR, allowing single-pass interferometry – on the end of a 60-meter (200-foot) mast that extended from the payload bay on ...

Digital Elevation Model
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, Natural satellite, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally produced Relief mapping (computer graphics), relief maps. A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top Canopy (biology), canopy or building roofs. While a DSM may be useful for Landscape planning, landscape modeling, Urban planning, city modeling and visualization applications, a DTM is often required for flood or drainage modeling, Land-use planning, land-use studies, geological applications, and other applications, and in planetary science. Terminology There is no universal usage of the terms ''digital elevation model'' (DEM), ''di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
