Who knows what the east west longitude of our country is? And the north south dimension?

Range: 76° east longitude to 135° east longitude, 4° north latitude 53° north latitude China geographical location four solstice point: northernmost:

Located in the East Eighth District, 53 degrees 33 minutes north latitude, Heilongjiang Province (Mohe County) Mohe north of the center line of the main channel of the Heilongjiang River Southernmost point: Located in the East Eighth District, 3 degrees 52 minutes north latitude, the Nansha Islands of the Zengmu Dark Sand (Eight Immortals Dark Sand and Standing Dark Sand in the southwest of the Zengmu Dark Sand, is the South China Sea has not been officially announced place names. Although they are farther south than the Zengmu Sands, it is generally believed that the Zengmu Sands are the southernmost and westernmost parts of China

Located in the East Fifth District, 73 degrees 40 minutes east longitude, it is generally believed to be the Wucha County of the Xinjiang Uygur Autonomous Region located in the Uzberi Pass (the real west solstice point is on the Pamir Plateau, on a snow-capped mountain slightly south of the junction of China, Kyrgyzstan and Tajikistan) The easternmost point: Located in the East Ninth District, 135 degrees 2 minutes and 30 seconds east longitude, the Black Blind Island at the confluence of the Heilongjiang River and the Ussuri River [the easternmost point of China is located at the intersection of the center line of the main channel of the Heilongjiang River and the Ussuri River, after the return of the Black Blind Island, It became the easternmost point of China's new state. The Manchu name of Black Blind Island is Mowuzhu Island, which means "horse's head".

On October 14, 2008, the western half was returned to China. 】

1. East longitude is positive, west longitude is negative. Longitude ranges from 180° to the east or 180° to the west.

The meridian is an auxiliary line hypothesized by humans for the convenience of measurement, defined as a semicircular arc on the great circle line connecting the north and south poles on the earth's surface. Any two meridians of equal length intersect at the north and south poles. Each meridian has its corresponding numerical value, called longitude.

The meridian indicates the north-south direction.

2. North latitude is positive, and south latitude is negative. The range of latitude is 90° to the north or 180° to the south.

Latitude refers to the normal line of a point on the ellipsoidal surface, and the line-plane angle between the normal of the point and the plane of the equator, its value is between 0 and 90 degrees. The latitude of a point north of the equator is called north latitude and is denoted as n; The latitude of a point located south of the equator is called south latitude and is denoted as s.

1. The latitude and longitude are divided into southern latitude and northern latitude, the southern latitude is represented by the capital letter S, and the northern latitude is represented by the capital letter N, for example: the latitude and longitude of Beijing is expressed as (116°E, 40°N).

2. Write latitude first, then longitude, for example: (41 46 n, 50 14 w).

3. Arabic numerals The first letter of the English direction, for example: 30°N, that is, 30 degrees north latitude.

If written in kanji, it should be:

North Latitude: East Longitude:

1. The meridian line, also known as the meridian, is an auxiliary line assumed by human beings for the convenience of measurement, and is defined as a semicircular arc on the great circle line connecting the north and south poles on the earth's surface. Any two meridians of equal length intersect at the north and south poles. Each meridian has its corresponding numerical value, called longitude.

The meridian indicates the north-south direction.

2. The parallel, like the meridian, is an auxiliary line assumed by human beings for the convenience of measurement, and is defined as the trajectory formed by the rotation of the earth at a certain point on the earth's surface. Any one of the wefts is round and parallel to each other. The length of the parallels is the circumference of the equator multiplied by the cosine of the latitude of the parallel, so the equator is the longest, and the farther away from the equator, the shorter the circumference, and it shrinks to 0 at the poles.

The parallels indicate the east-west direction.

The latitude of the Northern Hemisphere ranges from 0 degrees (equator) to the North Pole (90 degrees north latitude); The southern hemisphere travels from 0 degrees (equator) to the south pole (90 degrees south latitude).

The eastern and western hemispheres have nothing to do with latitude, but only longitude, which is: the eastern hemisphere is east of 20° west longitude and west of 160° east longitude; The western hemisphere is west of 20°W longitude and 160° east of east longitude.

The division of latitude is based on the 0° parallel of the Akabi Hail Road (0° parallel) and is divided by 90° to the north and south. The longitude is 0-180 degrees per mu, starting from Greenwich**, the eastward measure is the east longitude, and the west is the west longitude.

Longitude divides things.

1. The meridian is the line connecting the north and south poles, so it indicates the north-south direction;

2. Longitude is based on the 0 degree meridian (prime meridian) as the starting line, and is divided into 180 degrees to the east and west respectively, so it indicates the east-west direction.

3. The east-west longitude is bounded by 20 degrees west longitude and 160 degrees east longitude. East of 20 degrees west longitude to 160 degrees east longitude is the Eastern Hemisphere. West of 20 degrees west longitude to 160 degrees east longitude is the Western Hemisphere.

4. Longitude, a geographical term, generally refers to the ordinate of the spherical coordinate system, specifically the degree to the east or west of a place on the earth from a north-south line called the prime meridian.

5. According to international regulations, the longitude of the original site of the Greenwich Observatory in London, the capital of the United Kingdom, is set as the 0° longitude, and then extends to the left and right. The time zones are also divided into regions, with a difference of one hour every 15 degrees of longitude. As a basis of geography, longitude is the basic theory for understanding the rotation of the earth and the geographical division of regions, which needs to be carefully and accurately mastered.

Generally, the prime meridian, that is, the 0-degree meridian is the dividing line, east (right) is east longitude, west (left) is west longitude, and increases to both sides at the same time, until it meets at 180 degrees, each accounting for 180 degrees of longitude.

The north-south latitude is bounded by the equator, the part from the equator to the north pole is the north latitude, and the south pole is the south latitude. In the side view, the longitudinal one, the one that connects the north and south poles is the meridian, and the transverse one is the latitude.

1.Following the direction of the Earth's rotation, the longitude increases sequentially from 0° to 180°, and the longitude is represented by the symbol "e", such as 10°E, 20°E, 30°E, 40°E, etc.

2.Following the direction of the Earth's rotation, the longitude decreases in degrees to west, from 180° to 0°, and the symbol is used"w"Representation, such as 20°W, 30°W, 40°W, etc.

North latitude (equator) to 90° is north latitude, and the number of degrees from the equator to north increases sequentially; South of the 0° parallel (equator) to 90° is the southern latitude, and the number of degrees to the south gradually increases.

The west longitude west of the 0 degree meridian and the east of the 180 degree meridian are the west longitude, and the west longitude increases to the west.

East longitude east of the 0 degree meridian and west of the 180 degree meridian are east longitude, and the east longitude increases to the east.

North of the equator is the northern latitude, which increases to the north.

South of the equator is the southern latitude, which increases to the south.

Longitude from 0 degrees to 180 degrees.

Latitude from 0 degrees to 90 degrees.

Longitude divides things.

Longitude is the degree in which a point on Earth is east or west of a north-south alignment line called the prime meridian. The longitude of the prime meridian is 0°, and the longitude of the rest of the earth is 180° east or 180° west. Unlike latitude, which has an equator as a natural starting point, longitude has no natural starting point, and the line that is the prime meridian is chosen by the people.

Cartographers in the United Kingdom used the meridian through the Greenwich Observatory in London as the starting point, and other countries or people have used other meridians as starting points in the past, such as Rome, Copenhagen, Jerusalem, St. Petersburg, Pisa, Paris and Philadelphia.
