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.

How to look at the geographical latitude and longitude map
The latitude and longitude of geography are generally marked with east longitude, west longitude, south latitude and north latitude. But some drawings will only be marked with numbers, and there is no specific north-south latitude/east-west longitude.
For latitude, if the number goes north, it is north latitude; This number is between 0 and 90. 0 is the equator; Conversely, the lower the number, the south latitude.
For the judgment of longitude, first, if the longitude goes east and the number becomes larger, it is the east longitude, which is between 0- 180; On the contrary, if the number gets smaller to the east, it is the west longitude. Here you can imagine that turning the front of the earth to the opposite side will feel awkward, but it should still be conceivable. Look at longitude, longitude 0, longitude 180 is also very important. In addition, it should be noted that the Eastern Hemisphere refers to the range from 20 west longitude to160 east longitude.
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:
The first thing to declare is that 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! ! !

How does the compass look at latitude and longitude?
The compass can't see the latitude and longitude, it depends on the latitude and longitude. In the past, optical theodolite was used to determine the latitude and longitude through the change of time and the relative position and angle of celestial bodies. Now it can be seen directly with GPS, which is more accurate than optical theodolite.
The scale on the compass is not used to look at the latitude and longitude, but to determine the direction angle, which is helpful for us to combine the direction angle of the route on the map with the direction angle of the north-south direction, correctly choose the forward direction with small angle deviation, and avoid the wrong route selection caused by slight deviation.
What about latitude and longitude?
On the globe, you can see criss-crossing lines, which are longitude and latitude lines. The line connecting the North Pole and the South Pole is called meridian. The line perpendicular to the meridian is called the weft. The weft is a circle with different lengths. The longest latitude is the equator.
The longitude and latitude lines are drawn on globes and maps to determine the position and direction on the earth, but they are not drawn on the ground. However, you can easily see the longitude of your place: stand a bamboo pole on the ground. When the sun rises at the highest point at noon, the shadow of the bamboo pole is the longitude of your place. Because the meridian represents the north-south direction, it is also called the meridian.
On the map, a longitude line and a latitude line perpendicular to the longitude line can be drawn through any point on the earth's surface. So you can draw countless warps and wefts. How can we distinguish these warp and weft? The best way is to give each latitude and longitude a name, which is latitude and longitude. Use longitude to indicate the name of each longitude, and latitude to indicate the name of each latitude.
According to international regulations, the meridian passing through the original site of Greenwich Observatory in Britain is called 0 meridian, also called prime meridian. East longitude is called east longitude from 0 meridian; The western classics are called the western classics. Because the earth is a sphere, the east and west longitudes are 180 respectively. East longitude 180 and west longitude 180 are on the same meridian, that is, longitude 180.
The equator is the circle with the longest latitude, which is called 0 parallel. The latitude measured from the equator to the north is called north latitude; The south is called the south latitude. South latitude and north latitude are 90 degrees respectively. The North Pole is 90 degrees north latitude.
Because longitude connects the north and south poles, all the meridians are equal in length, indicating the north-south direction. The latitude represents both east and west directions. Warp and weft are perpendicular to each other and interwoven to form a warp and weft net. When looking at a map, we can use the latitude and longitude net to identify the direction, and we can also judge the latitude and longitude position of any point on the earth.
Meridians and latitudes can also divide the earth into several different hemispheres. Cut the earth along the equator like a watermelon, and the hemisphere north of the equator is called the northern hemisphere; The hemisphere south of the equator is called the southern hemisphere. If the earth is cut along the longitude of 20 west longitude and160 east longitude, the hemisphere from 20 west longitude to160 east longitude is called the eastern hemisphere; The western hemisphere is called the western hemisphere.
Latitude indicates the east-west direction. On the earth, every latitude is a circle parallel to the equator. The angle between the perpendicular to any point on the earth's surface and the equatorial plane is the latitude of latitude. The latitude of the equator is 0, the equator is 90 degrees south, the equator is 90 degrees north, 90 degrees south latitude is the South Pole, and 90 degrees north latitude is the North Pole. Usually people call 0-30 as low latitude, 30-60 as middle latitude and 60-90 as high latitude. During the revolution of the earth, the included angle between the axis of the earth and the plane of the revolution orbit is always 66 34', so the direct point of the sun rays on the earth always goes back and forth between 23 26' north latitude and 23 26' south latitude, so the latitude of 23 26' north latitude is called the Tropic of Cancer, and the latitude of 23 26' south latitude is called the Tropic of Cancer. It takes a year for the direct point of the sun to travel back and forth between the Tropic of Cancer and the Tropic of Capricorn. Every year on March 2 1 day (vernal equinox in the northern hemisphere), the sun points directly at the equator, and then the point of direct sunlight moves northward. On June 22nd (summer solstice in the northern hemisphere), the direct sunlight point moved to the Tropic of Cancer. Then the direct point of the sun returned to the south, returned to the equator again on September 2 1 day (vernal equinox in the northern hemisphere), and moved south to the tropic of Capricorn on February 22 12 (winter solstice in the northern hemisphere). Because the direct point of the sun moves between the Tropic of Cancer, when the direct point is on the Tropic of Cancer, all areas north of 66 34' in the northern hemisphere are in extreme daylight, while all areas south of 66 34' in the southern hemisphere are in extreme night. On the contrary, when the direction moves to the tropic of Capricorn, it enters the polar day south of 66 34' north latitude and the polar night north of 66 34' north latitude. So the latitude of 66 34' north latitude is called Arctic Circle, and the latitude of 66 34' south latitude is called Antarctic Circle. On the globe, longitude and latitude interweave to form a latitude and longitude network, which is the most basic coordinate system on the earth and is used to determine the direction and position of any point on the earth's surface. Only with the latitude and longitude network, it is possible to study the temporal and spatial distribution of everything on the earth's surface. In addition, the latitude and longitude network is also the most basic element for drawing various maps.
