Actually, it's easy to tell. You just need to remember the phrase "Tang Sanzang took the Western Classics". The vertical line is the east-west longitude and the horizontal line is the north-south latitude. You can also use "left west right east" and "up north and down south" to remember, because the vertical line (longitude) has left and right, while the horizontal line (latitude) is parallel up and down.
What do you think of the latitude or longitude of China?
China is located between 4 and 53 north latitude, with a span of nearly 50. China is located at 73 E-135 E, and the east-west longitude is 62.
How are latitudes and longitudes specified?
You are from junior high school, right? Yes, the following things can help you:
I. Longitude
1. Longitude: used to distinguish the degrees of each meridian.
2. Determination of zero degree: internationally, the meridian passing through the former site of Greenwich Observatory (Meridian Palace) in Britain is defined as 0 meridian; The 0-degree meridian is also called the prime meridian.
3. Degree division: East and west from 0 longitude are divided into 180 degrees respectively. ***360 degrees, and the maximum value is 180 degrees.
4. Representation: the east (right) of the 0 meridian is east longitude, represented by the letter E, and the west (left) of the 0 meridian is west longitude, represented by the letter W.
5. Degree change: East longitude gradually increases eastward (right); The west longitude gradually increases westward (left).
East longitude increases to the east (right) and west longitude decreases to the east (right). Dongda east longitude, west west longitude.
6. The division between the Eastern Hemisphere and the Western Hemisphere: international practice.
20 W and 160 E are two hemispheres separated by coils, which are called the eastern hemisphere and the western hemisphere respectively.
① from the longitude range: 20 W in the eastern hemisphere crosses 00 longitude to160 e; 20 W crosses the longitude of 180 to reach 160 E in the western hemisphere.
② Longitude: East longitude is less than160 E, and west longitude is less than 20 W in the Eastern Hemisphere; On the contrary, in the western hemisphere.
③ ③160 e and 20 W belong to neither the eastern hemisphere nor the western hemisphere.
7. Several special lines:
0: Primitive Meridian, the dividing line between east and west longitude, east longitude and west longitude.
180: the dividing line between east and west longitude, east longitude and west longitude.
0 and 180 belong to neither east nor west longitude. There are no symbols in the application.
20 W: the dividing line between the eastern hemisphere and the western hemisphere, with the eastern hemisphere in the east and the western hemisphere in the west.
160 E: the dividing line between the eastern hemisphere and the western hemisphere, with the western hemisphere in the east and the eastern hemisphere in the west.
20 W, 160 E does not belong to the eastern hemisphere or the western hemisphere. Do not judge the points on these two meridians in the eastern hemisphere and the western hemisphere.
Second, latitude.
1. Latitude: used to distinguish the degrees of each latitude.
2. Determination of zero degree: The longest latitude in the world is 0, which is the equator.
3. Degree division: the latitude of 0 is divided into 90 degrees north latitude and 90 degrees south latitude. *** 180 degrees, with a maximum of 90 degrees.
4. notation: north latitude is north latitude, symbol n, south latitude is south latitude, symbol s ..
Degree change: north latitude increases northward (upward) and south latitude decreases northward (upward).
The number of latitudes increases northward (upward) and southward (downward). North latitude, South latitude.
The equator belongs to neither north nor south latitude. There are no symbols in the application.
5. Division of Northern Hemisphere and Southern Hemisphere: two hemispheres separated by equatorial latitude circle, the northern hemisphere and the southern hemisphere. Because the dividing line between the north and south latitudes is the same as that between the north and south hemispheres, therefore:
The northern latitude is in the northern hemisphere and the southern latitude is in the southern hemisphere.
The equator belongs to neither the northern nor the southern hemisphere.
6. Division of middle and high latitude: 30 latitude is the dividing line of middle and low latitude, and 60 latitude is the dividing line of middle and high latitude. Latitude 30 and 60 does not belong to middle, high and low latitudes.
7. Several special similarities:
0: Equator, the longest latitude, 40,000 kilometers. It is not only the dividing line between the north and south latitudes, but also the dividing line between the north and south hemispheres. Most pictures are straight lines.
30 N: the dividing line between middle and low latitudes. North of middle latitude and south of low latitude.
30 S: the dividing line between middle and low latitudes. South of the mid-latitude, the northern latitude is lower.
60 N: the dividing line between middle and high latitudes. High latitude north and middle latitude south.
60' s: the dividing line between middle and high latitudes. North of middle latitude and south of high latitude.
23.5 N: Tropic of Cancer, the dividing line between tropical zone and north temperate zone; The northernmost boundary of direct sunlight is only on the line and south. A dotted line near the north of the equator.
23.5 degrees south latitude: Tropic of Capricorn, the dividing line between tropical zone and south temperate zone; The southernmost boundary of direct sunlight is only a straight line and direct sunlight in the north, and there is no direct sunlight in the south. A dotted line near the south of the equator.
66.5 N: the dividing line between the Arctic Circle, the northern frigid zone and the northern temperate zone; At the southernmost boundary of extreme day and night, there are extreme day and night on the line and in the north. The dotted line near the north pole.
66.5 S: the dividing line between Antarctic Circle, South Cold Zone and South Temperate Zone; The northernmost boundary of extreme day and night is the extreme day and night on the line and in the south. The dotted line near the south pole.
90 N: North Pole, the shortest latitude, with a length of 0km. The absolute north on the earth, the rest is his true north.
90 S: South Pole, with the shortest latitude and 0km long. The absolute south of the earth, the rest is his due south.

How to distinguish between latitude and longitude?
Most coordinate data expressed by latitude and longitude are composed of two sets of numbers. Generally speaking, the first set of numbers is longitude and the second set is latitude.
Longitude is generally between 0 and 180, which is divided into east longitude and west longitude. East longitude is indicated by the prefix e (east) in the coordinates, and west longitude is indicated by the prefix w (west) in the coordinates. Latitude ranges from 0 to 90, divided into north latitude and south latitude. North latitude is denoted by the prefix n (north) in coordinates, and south latitude is denoted by the prefix s (south) in coordinates.
First, there is a prefix.
Simply put, if there is a prefix, you can distinguish the latitude and longitude according to the prefix. If the prefix is e or w, it must be longitude, and if the prefix is n or s, it must be latitude (for example, e 78 36' 43 ",n 43 56' 32" means 78 36' 43 "east longitude and 43 56" north latitude.
Second, if there is no prefix.
Divided into the following situations:
First of all, if there is no prefix, you must know which hemisphere the coordinates are in, or where they are, such as the west of the northern hemisphere or the east of the southern hemisphere. Otherwise, there will be four sets of data, which cannot be judged!
Now, look down:
1) has a set of numbers over 90, so this set of numbers must be longitude (because latitude cannot exceed 90), for example.
113 36' 43 ",43 56' 32", with longitude ahead.
2) If both sets of numbers exceed 90, you must know the approximate location of the coordinates on the map. You can look at the approximate positions of the longitude and latitude of integers on the map first, such as 48 36' 43 ",43 56' 32", and you can look at E48 30' 00 "first.
3) Two sets of coordinates are too close, such as 48 36 ′ 43 ″, 481332 ″. Then ask this guy who gave you the coordinates, who are you kidding?
4) The two sets of coordinates are the same and need no explanation. That's longitude and that's latitude, which doesn't seem to mean much.
Third, there is an extreme situation.
As long as you give a set of numbers and know where the coordinates are, reference method 2 does not need a prefix! If there is no prefix, I won't tell you where it is. Go to the person who gave you the coordinates at once and slap him! ! !
Knocked for a long time, (I deleted it by mistake once when it was almost past% > _<%) Are you satisfied?
