Murano Lighthouse
Murano Lighthouse ( it, Faro dell'Isola di Murano) is an active lighthouse located in the south east part of the island of Murano in the Venetian Lagoon on the Adriatic Sea. Description The first lighthouse, built in 1912, was a metal skeletal tower on piles, which was deactivated in 1934 when became operational the current. The lighthouse consists of a two-stages cylindrical stone tower, high, with double balcony and lantern. The tower is painted white, on the upper stage are painted two black horizontal bands facing the range line, on the east side, in order to have the lighthouse more visible during the day. The Range Rear light is positioned at above sea level and emits an occulting white light in a 6 seconds period, visible up to a distance of . The lighthouse is completely automated and managed by the Marina Militare with the identification code number 4177.2 E.F. The Directional light is positioned at above sea level and emits one white flash in a 6 seconds period, v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focal Length
The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially collimated (parallel) rays are brought to a focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power. In most photography and all telescopy, where the subject is essentially infinitely far away, longer focal length (lower opti ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murano
Murano is a series of islands linked by bridges in the Venetian Lagoon, northern Italy. It lies about north of Venice and measures about across with a population of just over 5,000 (2004 figures). It is famous for its glass making. It was once an independent ''comune'', but is now a ''frazione'' of the ''comune'' of Venice. History Murano was initially settled by the Veneto#Roman period, Romans and from the sixth century by people from Altinum and Oderzo. At first, the island prospered as a fishing port and through its production of salt. It was also a centre for trade through the port it controlled on Sant'Erasmo. From the eleventh century, it began to decline as islanders moved to Dorsoduro. It had a Grand Council (Murano), Grand Council, like that of Venice, but from the thirteenth century, Murano was ultimately governed by a ''podestà'' from Venice. Unlike the other islands in the Venetian Lagoon, Lagoon, Murano minted its own coins. Early in the second millenniu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along the Croatian part of its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pile Lighthouse
A pile lighthouse is a type of lighthouse found in Australia and the United States. In the United States they are found primarily in Florida, including on open reefs adjacent to the Florida Keys. The pile lighthouses on the reefs in Florida are tall skeletal towers, with living and working quarters set high above the reach of storm waves. Some of the lights were converted screw-pile lighthouses, while others were built on piles driven directly into the sea bed.

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...
