A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
The Messina tram depot (in Italian: Deposito tranviario Messina) is the largest tram depot in Milan, Italy, and one of the largest in the world. [1] It is located at street number 14 of Via Messina, close to the Monumentale cemetery. The building of the depot, which dates back to 1912, is a prominent example of early 20th century Milanese industrial architecture, and one of the most important examples of cast-iron architecture in Italy. The depot is still in use by Azienda Trasporti Milanesi (ATM) public transport company. Due to its historical and architectural relevance, ATM occasionally opens the depot to visitors.
Italian is a Romance language of the Indo-European language family. Italian, together with Sardinian, is by most measures the closest language to Vulgar Latin of the Romance languages. Italian is an official language in Italy, Switzerland, San Marino and Vatican City. It has an official minority status in western Istria. It formerly had official status in Albania, Malta, Monaco, Montenegro (Kotor) and Greece, and is generally understood in Corsica and Savoie. It also used to be an official language in the former Italian East Africa and Italian North Africa, where it plays a significant role in various sectors. Italian is also spoken by large expatriate communities in the Americas and Australia. In spite of not existing any Italian community in their respective national territories and of not being spoken at any level, Italian is included de jure, but not de facto, between the recognized minority languages of Bosnia-Herzegovina and Romania. Many speakers of Italian are native bilinguals of both standardized Italian and other regional languages.
A tram is a rail vehicle which runs on tramway tracks along public urban streets; some include segments of segregated right-of-way. The lines or networks operated by tramcars are called tramways. Historically the term electric street railways was also used in the United States. In the United States, the term tram has sometimes been used for rubber-tyred trackless trains, which are unrelated to other kinds of trams.
Milan is a city in northern Italy, capital of Lombardy, and the second-most populous city in Italy after Rome, with the city proper having a population of 1,372,810 while its metropolitan city has a population of 3,245,308. Its continuously built-up urban area has a population estimated to be about 5,270,000 over 1,891 square kilometres. The wider Milan metropolitan area, known as Greater Milan, is a polycentric metropolitan region that extends over central Lombardy and eastern Piedmont and which counts an estimated total population of 7.5 million, making it by far the largest metropolitan area in Italy and the 54th largest in the world. Milan served as capital of the Western Roman Empire from 286 to 402 and the Duchy of Milan during the medieval period and early modern age.
The main structure of the building is composed of cast-iron piers surmounted by iron trusses; the roof comprises both glass panes and cotto tiles. The overall covered area is 29,062 m2 (312,820 sq ft). It houses about 150 trams as well as other vehicles devoted to railway maintenance and other support tasks. [2]
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers.
A truss is an assembly of beams or other elements that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes.
A tile is a thin object usually square or rectangular in shape. Tile is a manufactured piece of hard-wearing material such as ceramic, stone, metal, baked clay, or even glass, generally used for covering roofs, floors, walls, or other objects such as tabletops. Alternatively, tile can sometimes refer to similar units made from lightweight materials such as perlite, wood, and mineral wool, typically used for wall and ceiling applications. In another sense, a tile is a construction tile or similar object, such as rectangular counters used in playing games. The word is derived from the French word tuile, which is, in turn, from the Latin word tegula, meaning a roof tile composed of fired clay.
