Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Graham, Anderson, Probst & White
–
Graham, Anderson, Probst & White was a Chicago architectural firm that was founded in 1912 as Graham, Burnham & Co. This firm was the successor to D. H. Burnham & Co. through Daniel Burnhams surviving partner, Ernest R. Graham, and Burnhams sons, Hubert Burnham and Daniel Burnham Jr. In 1917, the Burnhams left to form their own practice, which eventually became Burnham Brothers, and Graham, – Graham, Peirce Anderson, Edward Mathias Probst, and Howard Judson White – formed the resulting practice. The firm also employed Victor Andre Matteson, Graham, Anderson, Probst & White was the largest architectural firm under one roof during the first half of the twentieth century. The firms importance to Chicagos architectural legacy cannot be overstated, nor can its connection to Burnham, the firm was headquartered in Burnhams own Railway Exchange Building. Its only close rival was the equally prolific Holabird and Root, GAP&W also created the iconic Terminal Tower in Cleveland and Federal Reserve Bank in Kansas City. Anderson died in 1924, with Graham and White following just weeks apart in 1936, surviving partner Edward M. Probst took over the firm, assisted by his sons Marvin Probst and Edward E. Probst. After Mr. Probsts death in 1942, son Marvin G. Probst took over as firm president, Edward E. Probst left the firm about 1947. Just prior to Marvin Probsts death in 1970, the firm was sold to an employee, from 1970 to 1993 William Surman was president of the firm. After his death in 1993, the practice was run by his son Robert Surman till the firm closed its doors in the fall of 2006 and those early buildings are still popular favorites today. The firms ultimate expression of the Art Deco style was found in its design of the 1931 Field Building and it was matched that year by Holabird and Roots equally stunning Chicago Board of Trade Building. After 1931, GAP&W for the most part stopped referencing the Beaux-Arts style, Field Museum of Natural History Conway Building,1913 Continental and Commercial Bank Building,1914 Marshall Field & Co. Shedd Aquarium, 1925–31 Pittsfield Building, 1926–27 State Line Generating Plant, 1926–29 Terminal Tower, Public Square, Cleveland, like most of the other prominent architectural firms of the early 20th Century, GAP&W frequently used sculpture to decorate its building designs. As was the custom of the era GAP&W had specific artists that preferred to work with

Van Sweringen brothers
–
Oris Paxton Van Sweringen and Mantis James Van Sweringen were brothers who became railroad barons in order to develop Shaker Heights, Ohio. They are better known as O. P. Van Sweringen and M. J. Van Sweringen, or by their collective nickname, the brothers came from a farming area near Wooster, Ohio. Their father was for a time an engineer in the oil fields of Pennsylvania, the family moved to Cleveland, Ohio, in about 1890. Neither brother married, the two shared a bedroom in their 54-room mansion, Roundwood Manor, on the grounds of their estate, Daisy Hill, in Hunting Valley. During their lifetimes, they gave interviews or made appearances in public, however. Before the establishment of Shaker Heights, Ohio, the brothers were land and building speculators in Cleveland, after being employed by others, and after suffering several early business failures, the brothers entered the real estate business. In 1909, the Van Sweringen brothers began exercising options on 1,399 acres of land owned by the North Union Community of the Society of Believers. Conceived and planned as a community similar to Baltimores Roland Park. This was achieved through a combination of planning, design review, Street planning for the new community used curved roads instead of the more usual grid pattern of streets found in many American communities. Three tree-lined boulevards extended eastward into the country, Moreland and Shaker boulevards center isles would be used for track bed for a planned interurban streetcar line. Both lines would share a route from Cleveland through Shaker Square where they would divide onto their own routes. The Van Sweringens designated Shaker Boulevard as a boulevard of mansions. Higher-density luxury apartments were planned for Moreland Boulevard, which was renamed Van Aken Boulevard in honor of the citys first mayor, Building in Shaker was controlled by a set of restrictive covenants and building guidelines established by the Van Sweringens and known as Shaker Standards. Shaker Standards prevented the community from being developed in any way contrary to how the Van Sweringens intended, Standards limited commercial development, rental property development, and residence style and size. Standards set roof slope angles, materials, finishes, and garage placement, all residences were required to be unique and designed by an architect. Duplex residences in the community were restricted to designated areas and were required to follow guidelines designed to give the impression that a structure was a single-family home. By 1920, the Van Sweringens controlled more than 4,000 acres in the community, since lots sold slowly, the brothers concluded that Shaker Heights needed a transportation system between the suburb and downtown. In 1913, the Van Sweringens established the Cleveland Interurban Railroad and this prompted the Van Sweringens to purchase land in the vicinity of Public Square in downtown Cleveland as early as 1909 to provide a terminus for their rapid transit line

Skyscraper
–
A skyscraper is a tall, continuously habitable building having multiple floors. When the term was used in the 1880s it described a building of 10 to 20 floors. Mostly designed for office, commercial and residential uses, a skyscraper can also be called a high-rise, for buildings above a height of 300 m, the term supertall can be used, while skyscrapers reaching beyond 600 m are classified as megatall. One common feature of skyscrapers is having a steel framework that supports curtain walls and these curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete. Modern skyscrapers walls are not load-bearing, and most skyscrapers are characterized by surface areas of windows made possible by steel frames. However, skyscrapers can have curtain walls that mimic conventional walls with a surface area of windows. Modern skyscrapers often have a structure, and are designed to act like a hollow cylinder to resist wind, seismic. To appear more slender, allow less wind exposure, and transmit more daylight to the ground, many skyscrapers have a design with setbacks, a relatively big building may be considered a skyscraper if it protrudes well above its built environment and changes the overall skyline. The maximum height of structures has progressed historically with building methods and technologies, the Burj Khalifa is currently the tallest building in the world. High-rise buildings are considered shorter than skyscrapers, the first steel-frame skyscraper was the Home Insurance Building in Chicago, Illinois in 1885. Even the scholars making the argument find it to be purely academic and this definition was based on the steel skeleton—as opposed to constructions of load-bearing masonry, which passed their practical limit in 1891 with Chicagos Monadnock Building. What is the characteristic of the tall office building. The force and power of altitude must be in it, the glory and it must be every inch a proud and soaring thing, rising in sheer exaltation that from bottom to top it is a unit without a single dissenting line. Some structural engineers define a highrise as any vertical construction for which wind is a significant load factor than earthquake or weight. Note that this criterion fits not only high-rises but some other tall structures, the word skyscraper often carries a connotation of pride and achievement. A loose convention of some in the United States and Europe draws the limit of a skyscraper at 150 m or 490 ft. The tallest building in ancient times was the 146 m Great Pyramid of Giza in ancient Egypt and it was not surpassed in height for thousands of years, the 14th century AD Lincoln Cathedral being conjectured by many to have exceeded it

Public Square, Cleveland
–
Public Square is the four-block central plaza of downtown Cleveland, Ohio. Based on an 18th-century New England model, it was part of the original 1796 town plat overseen by Moses Cleaveland, the 10-acre square is centered on the former intersection of Superior Avenue and Ontario Street. Clevelands three tallest buildings, Key Tower,200 Public Square and the Terminal Tower, face the square, a 125-foot-tall monument to Civil War soldiers and sailors occupies the southeast section of the square. City founder Moses Cleaveland and reformist mayor Tom L. Johnson each have statues on the square, Public Square was part of the Connecticut Land Companys original plan for the city, which were overseen by Moses Cleaveland in the 1790s. The square is signature of the layout for early New England towns, the square was added to the National Register of Historic Places on December 18,1975. A parking lot now faces the northwest quadrant of the square, a 12-story building, which was built on the spot in 1913, was demolished in 1990 to make way for the new Ameritrust Center, an 1, 197-foot skyscraper designed by New Yorks Kohn Pedersen Fox. Before construction began, Ameritrust was acquired by Society Bank, which was planning to construct. Because Society did not need two skyscrapers, plans for the Ameritrust building across the square were scrapped, the demolished Cuyahoga Building and Williamson Building formerly stood on the site of 200 Public Square. Public Square is often the site of rallies and civic functions. At the Balloonfest 86, close to 1.5 million balloons rose up from Public Square, engulfing the Terminal Tower, in collaboration with landscape architect James Corner, the city in 2009 began to explore concepts for a redesign of the square. In October 2011, Cleveland mayor Frank Jackson proposed his plan to redevelop the square, on October 23,2014, the Cleveland Landmarks Commission approved a plan which closed Ontario Street but kept Superior Avenue open to bus traffic, and kept the Soldiers and Sailors Monument prominent. The project began construction on March 9,2015, and was opened on June 30,2016. In total, ten U. S. and state routes meet at Public Square. It is the terminus of SR3, SR8, and SR43, the western terminus of US322, US422, SR14, and SR87. US6 passes through the square on Superior, and US20 enters from the west on Superior, US21 also terminated at Public Square until that route was truncated to Marietta in 1967. Public Square is adjacent to the Tower City–Public Square transit station, the HealthLine, a bus rapid transit line that travels along Euclid Avenue, terminates at Public Square.

Ohio /oʊˈhaɪ. oʊ/ is a Midwestern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, the states capital and largest city is Columbus. The state takes its name from the Ohio River, the name originated from the Iroquois word ohi-yo’, meaning great river or large creek. Partitioned from the Northwest Territory, the state was admitted to the Union as the 17th state on March 1,1803, Ohio is historically known as the Buckeye State after its Ohio buckeye trees, and Ohioans are also known as Buckeyes. Ohio occupies 16 seats in the United States House of Representatives, Ohio is known for its status as both a swing state and a bellwether in national elections. Six Presidents of the United States have been elected who had Ohio as their home state, Ohios geographic location has proven to be an asset for economic growth and expansion. Because Ohio links the Northeast to the Midwest, much cargo, Ohio has the nations 10th largest highway network, and is within a one-day drive of 50% of North Americas population and 70% of North Americas manufacturing capacity. To the north, Lake Erie gives Ohio 312 miles of coastline, Ohios southern border is defined by the Ohio River, and much of the northern border is defined by Lake Erie. Ohios neighbors are Pennsylvania to the east, Michigan to the northwest, Ontario Canada, to the north, Indiana to the west, Kentucky on the south, Ohio is bounded by the Ohio River, but nearly all of the river itself belongs to Kentucky and West Virginia. Ohio has only that portion of the river between the rivers 1792 low-water mark and the present high-water mark, the border with Michigan has also changed, as a result of the Toledo War, to angle slightly northeast to the north shore of the mouth of the Maumee River. Much of Ohio features glaciated plains, with a flat area in the northwest being known as the Great Black Swamp. Most of Ohio is of low relief, but the unglaciated Allegheny Plateau features rugged hills, in 1965 the United States Congress passed the Appalachian Regional Development Act, at attempt to address the persistent poverty and growing economic despair of the Appalachian Region. This act defines 29 Ohio counties as part of Appalachia, the worst weather disaster in Ohio history occurred along the Great Miami River in 1913. Known as the Great Dayton Flood, the entire Miami River watershed flooded, as a result, the Miami Conservancy District was created as the first major flood plain engineering project in Ohio and the United States. Grand Lake St. Marys in the west central part of the state was constructed as a supply of water for canals in the era of 1820–1850. For many years this body of water, over 20 square miles, was the largest artificial lake in the world and it should be noted that Ohios canal-building projects were not the economic fiasco that similar efforts were in other states. Some cities, such as Dayton, owe their emergence to location on canals. Summers are typically hot and humid throughout the state, while winters generally range from cool to cold, precipitation in Ohio is moderate year-round

North America
–
North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16. 5% of the land area. North America is the third largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7. 5% of the worlds population, North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago, the Classic stage spans roughly the 6th to 13th centuries. The Pre-Columbian era ended with the migrations and the arrival of European settlers during the Age of Discovery. Present-day cultural and ethnic patterns reflect different kind of interactions between European colonists, indigenous peoples, African slaves and their descendants, European influences are strongest in the northern parts of the continent while indigenous and African influences are relatively stronger in the south. Because of the history of colonialism, most North Americans speak English, Spanish or French, the Americas are usually accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass previously unknown by Europeans. In 1507, Waldseemüller produced a map, in which he placed the word America on the continent of South America. He explained the rationale for the name in the accompanying book Cosmographiae Introductio, for Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespuccis name, but in its feminine form America, following the examples of Europa, Asia and Africa. Later, other mapmakers extended the name America to the continent, In 1538. Some argue that the convention is to use the surname for naming discoveries except in the case of royalty, a minutely explored belief that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of Amairick. Another is that the name is rooted in a Native American language, the term North America maintains various definitions in accordance with location and context. In Canadian English, North America may be used to refer to the United States, alternatively, usage sometimes includes Greenland and Mexico, as well as offshore islands

New York City
–
The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over an area of about 302.6 square miles. Located at the tip of the state of New York. Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has described as the cultural and financial capital of the world. Situated on one of the worlds largest natural harbors, New York City consists of five boroughs, the five boroughs – Brooklyn, Queens, Manhattan, The Bronx, and Staten Island – were consolidated into a single city in 1898. In 2013, the MSA produced a gross metropolitan product of nearly US$1.39 trillion, in 2012, the CSA generated a GMP of over US$1.55 trillion. NYCs MSA and CSA GDP are higher than all but 11 and 12 countries, New York City traces its origin to its 1624 founding in Lower Manhattan as a trading post by colonists of the Dutch Republic and was named New Amsterdam in 1626. The city and its surroundings came under English control in 1664 and were renamed New York after King Charles II of England granted the lands to his brother, New York served as the capital of the United States from 1785 until 1790. It has been the countrys largest city since 1790, the Statue of Liberty greeted millions of immigrants as they came to the Americas by ship in the late 19th and early 20th centuries and is a symbol of the United States and its democracy. In the 21st century, New York has emerged as a node of creativity and entrepreneurship, social tolerance. Several sources have ranked New York the most photographed city in the world, the names of many of the citys bridges, tapered skyscrapers, and parks are known around the world. Manhattans real estate market is among the most expensive in the world, Manhattans Chinatown incorporates the highest concentration of Chinese people in the Western Hemisphere, with multiple signature Chinatowns developing across the city. Providing continuous 24/7 service, the New York City Subway is one of the most extensive metro systems worldwide, with 472 stations in operation. Over 120 colleges and universities are located in New York City, including Columbia University, New York University, and Rockefeller University, during the Wisconsinan glaciation, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth. The ice sheet scraped away large amounts of soil, leaving the bedrock that serves as the foundation for much of New York City today. Later on, movement of the ice sheet would contribute to the separation of what are now Long Island and Staten Island. The first documented visit by a European was in 1524 by Giovanni da Verrazzano, a Florentine explorer in the service of the French crown and he claimed the area for France and named it Nouvelle Angoulême. Heavy ice kept him from further exploration, and he returned to Spain in August and he proceeded to sail up what the Dutch would name the North River, named first by Hudson as the Mauritius after Maurice, Prince of Orange
