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

British Columbia Highway 99
–
The number of this highway is derived from the old U. S. Route 99, with which the highway originally connected. The highway currently connects with Interstate 5 at the international border, the current freeway alignment of Highway 99 between 8th Avenue in South Surrey and the North Arm of the Fraser River opened in 1962 as Hwy.99 and was called the Deas Throughway. Between 1964 and 1973, the alignment of Highway 99 was designated Highway 499. The Oak Street Bridge was built in 1957 to cross the North Arm Fraser River, tolls were collected at the crossings until April 11963. In 1957, the end of Highway 99 was moved from downtown Vancouver, across the Lions Gate Bridge and west to the village of Horseshoe Bay. Finally, in 1992, the just-paved Duffey Lake Road between Pemberton and Lillooet was made part of Highway 99, and the section of Highway 12 between Lillooet and Highway 97 was re-numbered 99. The portion of the highway between Lillooet and Pavilion was part of the route of the Old Cariboo Road, the total length of Highway 99 from the U. S. border to the Highway 97 junction is 409 kilometres. In 2006 the UKs The Guardian newspaper listed the Sea to Sky as the fifth best road trip worldwide. In the south, Highway 99 begins at the British Columbia – Washington State border crossing at Douglas, on the Canadian side of Peace Arch Park, the highway begins with a four-lane freeway configuration. Four km west, Highway 99 reaches its junction with Ladner Trunk Road, eight km north, Highway 99 reaches a junction with Highway 17A. Another 2 kilometres northwest, Highway 99 crosses into Richmond through the George Massey Tunnel, from Surrey to Vancouver, the speed limit is 100 kilometres per hour. Another 4 kilometres northwest, the freeway section of Highway 99 ends as the highway crosses the North Arm of the Fraser River, over the Oak Street Bridge. The 30-kilometre long route through Vancouvers city streets starts off going north on Oak Street to the intersection with West 70th Avenue. Highway 99 then goes west on West 70th Avenue, and then north along Granville Street for 7 kilometres and it crosses over False Creek into the downtown core. Highway 99 north goes through the area by way of Seymour Street and Georgia Street, through Stanley Park. In West Vancouver, Highway 99 goes west on Marine Drive and north on Taylor Way, Highway 99 shares the Upper Levels Highway with Highway 1 for 12 kilometres west, diverging from Highway 1 near the BC Ferries terminal at Horseshoe Bay. The Sea to Sky Highway is the given to the section of Highway 99 from Horseshoe Bay to Pemberton. From Squamish, it continues north for another 58 kilometres to Whistler, and then to Pemberton 32 kilometres later, where the Sea-to-Sky Highway ends and Duffey Lake Road begins

Granville Street
–
Granville Street is a major street in Vancouver, British Columbia, Canada, and part of Highway 99. Marine Drive and continues southeasterly towards the Arthur Laing Bridge that leads to Richmond, the community was known as Gastown after its first citizen - Jack Deighton, known as Gassy Jack. To gas is period English slang for to boast and to exaggerate, in 1870 the community was laid out as the township of Granville but everybody called it Gastown. The name Granville honours Granville Leveson-Gower, 2nd Earl Granville, who was British Secretary of State for the Colonies at the time of local settlement, during the 1950s, Granville Street attracted many tourists to one of the worlds largest displays of neon signs. Also, Otis writes that once dominated by movie theatres, pinball arcades, in April 2005, Capitol 6, a beloved 1920s-era movie theatre complex closed its doors. By August 2005, Movieland Arcade, located at 906 Granville Street became the last home of authentic,8 mm peep show film booths in the world. Landlords have been unable to find replacement tenants for many of these locations, for example. Granville Street is the second most expensive property in the game Canadian Monopoly, a letter from the Chair and Chief Elected Officer to Mayor Larry Campbell.

False Creek
–
False Creek is a short inlet in the heart of Vancouver. It separates downtown from the rest of the city and it was named by George Henry Richards during his Hydrographic survey of 1856-63. Science World is located at its end, with the Granville, Cambie. The Canada Line tunnel crosses underneath False Creek just west of the Cambie Bridge and it is one of the four major bodies of water bordering Vancouver along with English Bay, Burrard Inlet and the Fraser River. In 1986 it was the location of the Expo 86 Worlds Fair, human settlement in the Lower Fraser region began between 8,000 and 10,000 years ago, following the retreat of the Sumas Glacier at the end of the last ice age. According to Squamish-Sto, lo author and historian Lee Maracle, Vancouver was inhabited by “Downriver Halkomelem” speaking peoples, contact between Europeans and the indigenous peoples of present-day Vancouver occurred in June 1792. It has been estimated that shortly before the time of first contact and these epidemics, an 1830 Hudson’s Bay Company census documented 8,954 indigenous inhabitants in the region, although the census was probably incomplete due to the omitting of an unknown number of settlements. As a result of epidemics, the population of the Tsleil-Waututh was reduced to 41 individuals by 1812, shortly thereafter, a group of Tsleil-Waututh led by Khatsalahnough, a leader from Lil’wat, occupied present-day False Creek. At this time, large sand bars existed at the entrance to False Creek, from which False Creek’s indigenous name, Snauq is derived. False Creek, which lies in Musqueam territory, was a waterway, in addition to the Tsleil-Waututh. Prior to European settlement, False Creek extended as far east as what is now Clark Drive, with land reclamation extending into Burrard Inlet and False Creek for port and industrial uses, the landscape began to change dramatically. As a result, one nickname for False Creek was “Shit Creek”, in 1913, the Squamish residents of the Kitsilano Reserve, on the False Creek sandbar, were forced to relocate. According to Maracle, the settlement was burned following the forced evacuation. In 1916, the sandbar on which this settlement was located was built into Granville Island to create new industrial land, talk of draining and filling the inlet to Granville Street continued into the 1950s, but that never occurred. The False Creek area was the heartland of Vancouver through to the 1950s. As industry shifted to areas, the vicinity around False Creek started to deteriorate. In 1960, BC Forest Products plant and lumber storage facility on the side of False Creek caught fire in Vancouvers first-ever five-alarm blaze. Every piece of firefighting equipment and all of Vancouvers firefighters fought the blaze for hours, the future of False Creek south was subsequently shaped by debates on freeways, urban renewal, and the rise of citizen participation in urban planning

Vancouver
–
Vancouver is a coastal seaport city in Canada, located in the Lower Mainland region of British Columbia. As the most populous city in the province, the 2016 census recorded 631,486 people in the city, the Greater Vancouver area had a population of 2,463,431 in 2016, making it the third largest metropolitan area in Canada. Vancouver has the highest population density in Canada with over 5,400 people per square kilometre. With over 250,000 residents, Vancouver municipality is the fourth most densely populated city in North America behind New York City, San Francisco, and Mexico City according to the 2011 census. In that census, Vancouver was one of the most ethnically and linguistically diverse cities in Canada, Vancouver is classed as a Beta global city. In 2014, following thirty years in California, the annual TED conference made Vancouver its indefinite home, several matches of the 2015 FIFA Womens World Cup were played in Vancouver, including the final at BC Place Stadium. From that first enterprise, other stores and some hotels quickly appeared along the waterfront to the west, Gastown became formally laid out as a registered townsite dubbed Granville, B. I. As of 2014, Port Metro Vancouver is the third largest port by tonnage in the Americas, 27th in the world, the busiest and largest in Canada, and the most diversified port in North America. While forestry remains its largest industry, Vancouver is well known as an urban centre surrounded by nature, archaeological records indicate the presence of Aboriginal people in the Vancouver area from 8,000 to 10,000 years ago. The city is located in the territories of the Squamish, Musqueam. They had villages in various parts of present-day Vancouver, such as Stanley Park, False Creek, Kitsilano, Point Grey, the city takes its name from George Vancouver, who explored the inner harbour of Burrard Inlet in 1792 and gave various places British names. The explorer and North West Company trader Simon Fraser and his became the first known Europeans to set foot on the site of the present-day city. In 1808, they travelled from the east down the Fraser River, perhaps as far as Point Grey. The Fraser Gold Rush of 1858 brought over 25,000 men, mainly from California, to nearby New Westminster on the Fraser River, on their way to the Fraser Canyon, a sawmill established at Moodyville in 1863, began the citys long relationship with logging. It was quickly followed by mills owned by Captain Edward Stamp on the shore of the inlet. This mill, known as the Hastings Mill, became the nucleus around which Vancouver formed, the mills central role in the city waned after the arrival of the Canadian Pacific Railway in the 1880s. It nevertheless remained important to the economy until it closed in the 1920s. The settlement which came to be called Gastown grew up quickly around the original makeshift tavern established by Gassy Jack Deighton in 1867 on the edge of the Hastings Mill property

Cantilever
–
A cantilever is a rigid structural element, such as a beam or a plate, anchored at only one end to a support from which it is protruding. Cantilevers can also be constructed with trusses or slabs, when subjected to a structural load, the cantilever carries the load to the support where it is forced against by a moment and shear stress. Cantilevers are widely found in construction, notably in cantilever bridges and balconies, in cantilever bridges the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a truss bridge. A cantilever in a timber framed building is called a jetty or forebay. In the southern United States a historic barn type is the barn of log construction. Temporary cantilevers are used in construction. The partially constructed structure creates a cantilever, but the structure does not act as a cantilever. This is very helpful when temporary supports, or falsework, cannot be used to support the structure while it is being built. So some truss arch bridges are built each side as cantilevers until the spans reach each other and are then jacked apart to stress them in compression before final joining. Nearly all cable-stayed bridges are built using cantilevers as this is one of their chief advantages, many box girder bridges are built segmentally, or in short pieces. This type of construction lends itself well to balanced cantilever construction where the bridge is built in both directions from a single support and these structures are highly based on torque and rotational equilibrium. In an architectural application, Frank Lloyd Wrights Fallingwater used cantilevers to project large balconies, the East Stand at Elland Road Stadium in Leeds was, when completed, the largest cantilever stand in the world holding 17,000 spectators. The roof built over the stands at Old Trafford Football Ground uses a cantilever so that no supports will block views of the field, the old, now demolished Miami Stadium had a similar roof over the spectator area. The largest cantilever in Europe is located at St James Park in Newcastle-Upon-Tyne, less obvious examples of cantilevers are free-standing radio towers without guy-wires, and chimneys, which resist being blown over by the wind through cantilever action at their base. Another use of the cantilever is in fixed-wing aircraft design, pioneered by Hugo Junkers in 1915, early aircraft wings typically bore their loads by using two wings in a biplane configuration braced with wires and struts. They were similar to bridges, having been developed by Octave Chanute. The wings were braced with crossed wires so they would stay parallel, the cables and struts generated considerable drag, and there was constant experimentation for ways to eliminate them

Truss bridge
–
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements usually forming triangular units. The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads, Truss bridges are one of the oldest types of modern bridges. The basic types of truss bridges shown in this article have simple designs which could be analyzed by 19th-. A truss bridge is economical to construct because it uses materials efficiently, the nature of a truss allows the analysis of the structure using a few assumptions and the application of Newtons laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the components meet. This assumption means that members of the truss will act only in tension or compression, a more complex analysis is required where rigid joints impose significant bending loads upon the elements, as in a Vierendeel truss. The central vertical member stabilizes the upper member, preventing it from buckling. If the top member is sufficiently stiff then this element may be eliminated. If the lower chord is sufficiently resistant to bending and shear, the vertical elements may be eliminated. The ability to distribute the forces in various ways has led to a variety of truss bridge types. In other cases the appearance of the structure may take on greater importance, a pure truss can be represented as a pin-jointed structure, one where the only forces on the truss members are tension or compression, not bending. This is used in the teaching of statics, by the building of bridges from spaghetti. Spaghetti is brittle and although it can carry a modest tension force, a model spaghetti bridge thus demonstrates the use of a truss structure to produce a usefully strong complete structure from individually weak elements. In 1820 a simple form of truss, Towns lattice truss, was patented, few iron truss bridges were built in the United States before 1850. Truss bridges became a type of bridge built from the 1870s through the 1930s. Examples of these still remain across the US, but their numbers are dropping rapidly. As metal slowly started to replace timber, wrought iron bridges in the US started being built on a scale in the 1870s. Bowstring truss bridges were a common truss design during this time, companies like the Massillon Bridge Company of Massillon, Ohio and the King Bridge Company of Cleveland, Ohio became well-known, as they marketed their designs to cities and townships

British Columbia
–
British Columbia is the westernmost province of Canada, with a population of more than four million people located between the Pacific Ocean and the Rocky Mountains. British Columbia is also a component of the Pacific Northwest and the Cascadia bioregion, along with the U. S. states of Idaho, Oregon, Washington and Alaska. The first British settlement in the area was Fort Victoria, established in 1843, subsequently, on the mainland, the Colony of British Columbia was founded by Richard Clement Moody and the Royal Engineers, Columbia Detachment, in response to the Fraser Canyon Gold Rush. Port Moody is named after him, in 1866, Vancouver Island became part of the colony of British Columbia, and Victoria became the united colonys capital. In 1871, British Columbia became the province of Canada. Its Latin motto is Splendor sine occasu, the capital of British Columbia remains Victoria, the fifteenth-largest metropolitan region in Canada, named for the Queen who created the original European colonies. The largest city is Vancouver, the third-largest metropolitan area in Canada, the largest in Western Canada, in October 2013, British Columbia had an estimated population of 4,606,371. British Columbia evolved from British possessions that were established in what is now British Columbia by 1871, First Nations, the original inhabitants of the land, have a history of at least 10,000 years in the area. Today there are few treaties and the question of Aboriginal Title, notably, the Tsilhqotin Nation has established Aboriginal title to a portion of their territory, as a result of the recent Supreme Court of Canada decision. BCs economy is diverse, with service producing industries accounting for the largest portion of the provinces GDP and it is the endpoint of transcontinental railways, and the site of major Pacific ports that enable international trade. Though less than 5% of its vast 944,735 km2 land is arable and its climate encourages outdoor recreation and tourism, though its economic mainstay has long been resource extraction, principally logging, farming, and mining. Vancouver, the provinces largest city and metropolitan area, also serves as the headquarters of many western-based natural resource companies and it also benefits from a strong housing market and a per capita income well above the national average. The Northern Interior region has a climate with very cold winters. The climate of Vancouver is by far the mildest winter climate of the major Canadian cities, the provinces name was chosen by Queen Victoria, when the Colony of British Columbia, i. e. the Mainland, became a British colony in 1858. The current southern border of British Columbia was established by the 1846 Oregon Treaty, British Columbias land area is 944,735 square kilometres. British Columbias rugged coastline stretches for more than 27,000 kilometres and it is the only province in Canada that borders the Pacific Ocean. British Columbias capital is Victoria, located at the tip of Vancouver Island. Only a narrow strip of the Island, from Campbell River to Victoria, is significantly populated, much of the western part of Vancouver Island and the rest of the coast is covered by thick, tall and sometimes impenetrable temperate rainforest

Granville Island
–
Granville Island is a peninsula and shopping district in Vancouver, British Columbia, Canada. It is located across False Creek from Downtown Vancouver, under the end of the Granville Street Bridge. The peninsula was once an industrial manufacturing area, but today it is now a hotspot for Vancouver tourism, the area has received much acclaim in recent years for its buildings and shopping experience. The area was named after Granville Leveson-Gower, 2nd Earl Granville, the island is home to 275 businesses and facilities that employ more than 2,500 people and generates more than $215-million in economic activity each year. The Granville Island Public Market features a market, day vendors. There are 50 permanent retailers and over one-hundred day vendors in stalls throughout the market selling a variety of artisan cottage-industry foods and handmade crafts on a rotating schedule. Granville Island Brewing Co. is also the name of a company which originated on Granville Island in 1984. Ocean Concrete is the tenant on the island, having set up shop there in 1917. Granville Island is the location of several annual festivals, including the Vancouver International Childrens Festival, the Vancouver Fringe Festival. Other water transportation options include a service to Bowen Island provided by English Bay Launch. There is also a route operated by the Vancouver Downtown Historic Railway. During the 2010 Winter Olympics, a service was offered between Granville Island and SkyTrains Olympic Village in the SE False Creek neighbourhood. This streetcar is now shut down. The peninsula was used by First Nations as a fishing area. The city of Vancouver was called Granville until it was renamed in 1886, but the name was kept and given to Granville Street. False Creek in the late 19th century was more than twice todays size, a British Admiralty Chart of 1893 shows the island in greater detail and conforming even more accurately to todays Granville Island. The Federal government put a stop to the work as a menace to navigation, in 1915, with the port of Vancouver growing, the newly formed Vancouver Harbour Commission approved a reclamation project in False Creek for an industrial area. A 14-hectare island, connected to the mainland by a combined road, almost 760,000 cubic metres of fill was dredged largely by a man named Alvin Kingston, from the surrounding waters of False Creek to create the island under the Granville Street Bridge
