List Of Tallest Buildings In Hamburg
This list of tallest buildings in Hamburg ranks high-rise buildings and some important landmarks that reach a height of 50 meters (164 feet). The tallest freestanding structure in the city is the 279-meter-high Heinrich-Hertz-Turm, a television tower built in 1968. Hamburg's city centre is dominated by church towers; Hamburg is the city with the most churches taller than 100 meters. High-rise buildings, on the other hand, are found in smaller clusters in the HafenCity, at Berliner Tor in St. Georg, in the Hafenkrone in St. Pauli and in Mundsburg in Hamburg-Nord. The criterion for skyscrapers is usually a height of 150 meters or more. So far, no Hamburg building has reached this mark, but Hamburg has made a first attempt in this direction with the Elbtower. However, construction was halted at the end of October 2023 as the developer failed to make payments to the construction company.

Planten Un Blomen
Planten un Blomen () is an urban park with a size of in the inner-city of Hamburg, Germany. The name ''Planten un Blomen'' is Low German for "Plants and Flowers". History After the destruction of Hamburg's old city fortifications in the early 1800s, a green belt was established in their place; part of this makes up the modern Planten un Blomen. The first plant was a Platanus, planted by Johann Georg Christian Lehmann in November 1821. It can be seen next to the Hamburg Dammtor station entrance of the park. The area was previously home to a zoo and a cemetery, the latter of which had to be dismantled for its construction. The modern park was established in 1933; in accordance with Nazi ideology, only German plants were included at the time. In 1953 and 1973 the Internationale Gartenbauausstellung (International Horticulture Show, IGA) were held at the park. Overview The park has water-light concerts, public theater and music performances. In addition to the main gardens, t ...

Microwave Radio Relay
Microwave transmission is the Data transmission, transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300 MHz to 300 GHz (1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles. Although an experimental microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication. During the war, the British Army introduced the Wireless Set No. 10, which used microwave relays to multiplexing, multiplex eight telephone channels over long ...

DGPS
Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS can increase accuracy of positional data by about a thousandfold, from approximately to . DGPSs consist of networks of fixed position, ground-based reference stations. Each reference station calculates the difference between its highly accurate known position and its less accurate satellite-derived position. The stations broadcast this data locally—typically using ground-based transmitters of shorter range. Non-fixed (mobile) receivers use it to correct their position by the same amount, thereby improving their accuracy. The United States Coast Guard (USCG) previously ran DGPS in the United States on longwave radio frequencies between and near major waterways and harbors. It was discontinued in March 2022. The USCG's DGPS was known as NDGPS (Nationwide DGPS) and was jointly administered by the Coast Guard and the United ...

Towers With Revolving Restaurants
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Buildings And Structures In Hamburg-Mitte
A building or edifice is an enclosed Structure#Load-bearing, structure with a roof, walls and window, windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the :Human habitats, human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much architecture, artistic expression. ...

Communication Towers In Germany
Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether Intention, unintentional or failed transmissions are included and whether communication not only transmits semantics, meaning but also creates it. Models of communication are simplified overviews of its main components and their interactions. Many models include the idea that a source uses a code, coding system to express information in the form of a message. The message is sent through a Communication channel, channel to a receiver who has to decode it to understand it. The main field of inquiry investigating communication is called communication studies. A common way to classify communication is by whether information is exchanged between humans, members of other species, or non-living entities such as computers. For human communication, a central contrast is between Verbal communication, verbal and non-verbal communication. Verba ...

Observation Towers In Hamburg
Observation in the natural sciences is an act or instance of noticing or perceiving and the acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, the absence or presence of a property is noted and the observed phenomenon described, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring. Science The scientific method requires observations of natural phenomena to formulate and test hypotheses. It consists of the following steps: # Ask a question about a phenomenon # Make observations of the phenomenon # Formulate a hypothesis that tentatively answers the question # Predict logical, observable consequences of the hypothesis that have not yet been investigated # ...
