From Hyde Park to Greenwich Observatory, guide to the location of Greenwich Observatory

1. Location of Greenwich Observatory

Greenwich Observatory is located in London, England.

Specifically, it is located on a hill in Greenwich Park, London, overlooking the River Thames.

2. Where is Greenwich Observatory located?

Greenwich Observatory, also known as Greenwich Observatory.

Built in 1675. At that time, the shipping industry in the United Kingdom and the United States was developing rapidly. In order to meet the need for measuring longitude at sea, the British authorities decided to establish an observatory in the Royal Greenwich Gardens on the Thames River, about 20 kilometers from the center of the southeastern suburbs of London. In 1884, the meridian passing through the observatory was established as the standard reference meridian for global time and longitude measurements, also known as the prime meridian and zero degree longitude.

3. Greenwich Observatory map location

Greenwich is a district in Greater London, England. Located in southeast London, on the south bank of the Thames. From 1975 to 1948, the Royal Greenwich Observatory was established. The International Longitude Conference held in Washington in 1884 decided to use the meridian passing through Greenwich as the prime meridian, which is the starting point for calculating time and geographical longitude in the world.

After World War II, the observatory was moved to Hurst Manju on the southeast coast, and the original site has been changed to the Royal Naval College, the National Maritime Museum, etc. There is a bronze plaque engraved with the zero degree of the Greenwich meridian. Greenwich is located southeast of London and is the starting point of the Earth's meridian. In addition to being the basis for Greenwich Mean Time, this Prime Meridian divides the Earth in half. It was listed as a world cultural heritage in 1997.

4. Where is the Greenwich Observatory now?

The original site of the Greenwich Observatory in the United Kingdom is 0 degrees east longitude.

Longitude 0 is the starting point for calculating east-west longitude. In 1884, an international conference decided to use the meridian passing through the meridian center of the Greenwich Observatory in England as the prime meridian. After 1957, the Greenwich Observatory moved to another location. In 1968, the Conventional International Origin (CIO) was used as the Earth's origin while the longitude origin remained virtually unchanged.

Before the 19th century, many countries adopted the meridian passing through Hierro, Canary Islands in the Atlantic Ocean. That meridian is equivalent to today's latitude of 17 degrees south, 39 minutes and 46 seconds west longitude. In the first half of the 19th century, many countries regarded the meridian passing through their main observatories as the prime meridian. As a result, there are several prime meridians in the world at the same time, which brings a lot of inconvenience to later navigation and geodetic survey. Therefore, on October 13, 1884, the Congress of International Astronomers in Washington decided to use the meridian passing through Greenwich, southeast of London, England, as the prime meridian, as the starting point for calculating geography and the world's standard time zone. Later, this day was designated as International Standard Time Day. Longitude is measured east and west from the prime meridian and is 0-180 or 0-12 hours respectively. East longitude is east of the prime meridian, and west longitude is west. The intersection point E between the prime meridian and the equator is used as the origin of longitude in global longitude measurements. After 1957, the Greenwich Observatory was relocated. Several observatories with good long-term stability were used internationally to maintain the origin of longitude, and their original longitude values ??were used to calculate their origin of longitude. The point that serves as the global longitude origin is then determined and maintained by the difference between the average of these longitude origins and point E. In 1968, the conventional international origin (cio) was used as the origin of the earth's poles, and the meridian passing through the conventional international origin, the origin of longitude and the mean observatory was called the prime meridian

5. Latitude of Greenwich Observatory

Central London is located at 51 degrees 30 minutes north latitude.

Affected by the North Atlantic current and London's westerly winds, London has a temperate maritime climate with small temperature differences throughout the four seasons, cool in summer and warm in winter, with the winter temperature around 6°C.

London straddles both sides of the Thames River and is dominated by plains, with flat and low terrain and rich tourism resources. There are the Thames River, Tower Bridge, Swiss Re Building, Palace of Westminster, Elizabeth Tower, Millennium Bridge, London Eye, Greenwich Observatory, Canary Wharf, Millennium Dome and St. Paul's Cathedral, etc.

Tower Bridge is the most famous attraction. This suspension bridge across the Thames River is a symbol of London. It is known as the main entrance to London and is the most famous of the 15 bridges on the Thames River. The upper level of Tower Bridge is a wide suspended walkway, allowing pedestrians to enjoy the beautiful views on both sides of the Thames, including St Paul's American Cathedral, the Shard and other landmarks. The lower level is accessible by vehicle. When the 10,000-ton ship passes the Thames, you can see the opening of the famous Tower Bridge.

Beijing to London is more than 8,000 kilometers, and the direct flight takes about 11 hours. Shanghai, Guangzhou, Hong Kong and other cities have direct flights to London. London is the world's largest financial center, controlling 45% of the world's foreign exchange transactions and the pricing power of commodities such as gold, silver and crude oil. This is also the world's largest banking, insurance, futures and shipping center in the United States.

: Greenwich Time 6. The Greenwich Observatory is located at

longitude 0.

Greenwich is a borough of London, England, located in southeast London on the south bank of the Thames River. From 1975 to 1948, the Royal Greenwich Observatory was established.

The International Longitude Conference held in Washington in 1884 decided to use the meridian passing through Greenwich as the prime meridian, which is also the starting point for calculating time and geographical longitude in the world.

7. Greenwich Observatory Map

First find the South Pole and the North Pole. The line connecting the South Pole to the North Pole is the meridian. The meridian passing through the Greenwich Observatory in London is 0 degrees longitude, gradually increasing to 180 degrees east longitude and 180 degrees west longitude.

Latitude: First find the equator, which is the line connecting points with equal distances between the North and South Pole, with a degree of 0. Then, the line parallel to the equator is the latitude, gradually increasing to 90 degrees north latitude and gradually increasing to 90 degrees south latitude.

9. Greenwich Observatory coordinates

Latitude represents the X coordinate, indicating the east-west direction, and longitude represents the Y coordinate, indicating the north-south direction.

The origin of China's coordinates is on a high platform in Yongle Town, Jingyang County, Xianyang City, Shaanxi Province. The origin is a small sphere of copper set on a marble foundation stone. There is an antique tower built on it.

Geographical coordinates are spherical coordinates that represent the location of ground points using longitude and latitude. The geographical coordinate system uses the earth's s-axis as the polar axis, and all planes passing through the earth's north and south poles are called meridian planes. Geographic coordinates are the spherical coordinates of a ground point expressed in latitude and longitude. The intersection of the meridian plane and the Earth's ellipsoid is called the meridian plane or meridian plane. Internationally, the meridian passing through the Greenwich Observatory in London, England, is the starting meridian (0), also called the prime meridian. Starting from the starting meridian, the east and west are counted as 180, the east is called east longitude, and the west is called west longitude.

10. The city where the original site of the Greenwich Observatory is located

Yes. Laiyang Toutiao

The longitude east of the prime meridian is east longitude, and the longitude west of the prime meridian is west longitude. The maximum east-west longitude is 180 degrees. The maximum late latitude is 0 degrees. The maximum north and south latitudes are 90 degrees, located at the North Pole and South Pole respectively.

The prime meridian refers to the zero-degree longitude on the earth, indicating the north-south direction. All longitude lines are equal in length, and the degrees marked on the longitude lines are longitude.
