Observation Tower
An observation tower is a structure used to view events from a long distance and to create a full 360 degree range of vision to conduct long distance observations. Observation towers are usually at least tall and are made from stone, iron, and wood. Many modern towers are also used as TV towers, restaurants, or churches. The towers first appeared in the ancient world, as long ago as the Babylonian Empire. Observation towers that are used as guard posts or observation posts over an extended period to overlook an area are commonly called watchtowers instead. Construction and usage Observation towers are an easily visible sight on the countryside, as they must rise over trees and other obstacles to ensure clear vision. Older control rooms have often been likened to medieval chambers. The heavy use of stone, iron, and wood in their construction helps to create this illusion. Modern towers frequently have observation decks or terraces with restaurants or on the roof of mountain st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auersberg Observation Tower (aka)
Auersberg is a mountain in the Ore Mountains in Saxony, southeastern Germany. Auersberg is a 1018.2 m above sea level. It is located in the district of Wildenthal not far from the Czech Republic, Czech border southeast of Eibenstock and northwest of Johanngeorgenstadt. Location and Geology Auersberg belongs to Wildenthal, which has been a district of Eibenstock since 1994. North of the Auersberg lies the Sosa dam. Below the summit there is a parking lot. When ascending to the Auersberg, you cross the Johanngeorgenstadt district of Sauschwemme. The main type of rock is medium-grained granite, which includes tourmaline. Also included in the granite are silver, tin and iron compounds, which were mined as early as the 16th century. At the peak of mining activity, there were up to 300 mines on the Auersberg. These included the Churhaus Saxony. In addition to the aforementioned rocks, quartz and slate have been proven to occur in veins on the summit. See also List of mountain ...

Watchtower
A watchtower or watch tower is a type of fortification used in many parts of the world. It differs from a regular tower in that its primary use is military and from a turret in that it is usually a freestanding structure. Its main purpose is to provide a high, safe place from which a sentinel or guard may observe the surrounding area. In some cases, non-military towers, such as religious towers, may also be used as watchtowers. History Military watchtowers The Romans built numerous towers as part of a system of communications, one example being the towers along Hadrian's Wall in Britain. Romans built many lighthouses, such as the Tower of Hercules in northern Spain, which survives to this day as a working building, and the equally famous lighthouse at Dover Castle, which survives to about half its original height as a ruin. In medieval Europe, many castles and manor houses, or similar fortified buildings, were equipped with watchtowers. In some of the manor houses of wester ...

Fire Lookouts
A fire lookout (partly also called a fire watcher) is a person assigned the duty to look for fire from atop a building known as a fire lookout tower. These towers are used in remote areas, normally on mountain tops with high elevation and a good view of the surrounding terrain, to spot smoke caused by a wildfire. Once a possible fire is spotted, "Smoke Reports", or "Lookout Shots" are relayed to the local Emergency Communications Center (ECC), often by radio or phone. A fire lookout can use a device known as an Osborne Fire Finder to obtain the radial in degrees off the tower, and the estimated distance from the tower to the fire. Part of the lookout's duties include taking weather readings and reporting the findings to the Emergency Communications Center throughout the day. Often several lookouts will overlap in coverage areas and each will “cross” the same smoke, allowing the ECC to use triangulation from the radials to achieve an accurate location of the fire.

Fire Lookout Towers
A fire lookout tower, fire tower or lookout tower, provides housing and protection for a person known as a "fire lookout" whose duty it is to search for wildfires in the wilderness. It is a small building, usually on the summit of a mountain or other high vantage point, to maximize viewing distance and range, known as ''view shed''. From this vantage point the fire lookout can see smoke that may develop, determine the location by using a device known as an ''Osborne Fire Finder'', and call fire suppression personnel to the fire. Lookouts also report weather changes and plot the location of lightning strikes during storms. The location of the strike is monitored for a period of days afterwards, in case of ignition. A typical fire lookout tower consists of a small room, known as a ''cab,'' atop a large steel or wooden tower. Historically, the tops of tall trees have also been used to mount permanent platforms. Sometimes natural rock may be used to create a lower platform. In cases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Needle At Dusk 2011 - 02
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "space ...

Funkturm Berlin
The Berliner Funkturm or Funkturm Berlin (Berlin Radio Tower) is a former broadcasting tower in Berlin. Constructed between 1924 and 1926 to designs by the architect Heinrich Straumer, it was inaugurated on 3 September 1926, on the occasion of the opening of the third Große Deutsche Funkausstellung (Great German Radio Exhibition) in the grounds of the Messe Berlin trade fair in the borough of Charlottenburg-Wilmersdorf. Nicknamed ''der lange Lulatsch'' ("the lanky lad"), the tower is one of the best-known points of interest in the city of Berlin and, while no longer used for broadcasting purposes, it remains a protected monument. Construction method The tower is built as one large steel framework construction, similar to the Eiffel Tower in Paris. The and approximately 600-metric ton radio tower was originally planned strictly as a transmitting tower, but later additions included a restaurant at a height of approximately 52 m, and observation deck at a height of approxim ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Control Tower
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advis ...

Majdanek Toren
Majdanek (or Lublin) was a Nazi concentration and extermination camp built and operated by the SS on the outskirts of the city of Lublin during the German occupation of Poland in World War II. It had seven gas chambers, two wooden gallows, and some 227 structures in all, placing it among the largest of Nazi concentration camps. Although initially intended for forced labor rather than extermination, the camp was used to murder people on an industrial scale during Operation Reinhard, the German plan to murder all Polish Jews within their own occupied homeland. The camp, which operated from 1 October 1941 to 22 July 1944, was captured nearly intact. The rapid advance of the Soviet Red Army during Operation Bagration prevented the SS from destroying most of the camp's infrastructure, and Deputy Camp Commandant Anton Thernes failed to remove most incriminating evidence of war crimes. The camp was nicknamed Majdanek ("little Majdan") in 1941 by local residents, as it was adjacen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amusement Park
An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects. Amusement parks evolved from European fairs, pleasure gardens, and large picnic areas, which were created for people's recreation. World's fairs and other types of international expositions also influenced the emergence of the amusement park industry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
