For geographical problems, fill in the number of latitude and longitude, know the latitude and longi

1.The 10 degrees of latitude shown on the map are 10 degrees north and 10 degrees south.

Then a vertical grid is 20 degrees, and north is 30, 50, and 70 degrees.

The same is true for longitude, which is 10 and 30 degrees to the west.

2.Because the Earth is round, from the equator to the poles, the distance between the same longitude will become smaller and smaller, you can look at the globe.

So A is shorter than B.

3.This might require a bit of math.

In the case of a sphere, the central angle corresponding to the length of c = the central angle perpendicular to the line segment b to 10 degrees south latitude, then the length of c is equal to the line segment just made, and we assume that this line segment is called d.

It may be a bit difficult to understand here, d=b, because the corresponding central angle is the same.

So c=b

Just now we compared the length of ab and now we can get c>a

1.From left to right: 30 degrees W, 10 degrees W; From top to bottom: 70 degrees N, 50 degrees N, 30 degrees N

The line spans 10 degrees of longitude and is at 60 degrees of latitude n, so a=111 cos60 degrees 10=555

b is located at the equator and spans 20 degrees of longitude, so b = 111 20 = 2220 so 4 a = b

Across 10 degrees of latitude, at 20 degrees e, so c=111 10=1110, so 2 a=c

The difference in latitude between 1 and 1 on the same meridian is approximately equal to 111 km; A difference in longitude of 1 on the same latitude is approximately equal to 111 km (cos latitude).

Knowing the latitude and longitude of two points, the following calculations are required to calculate the straight-line distance between the two places:

Convert the latitude and longitude of the two places to (x,y)(x',y') to calculate the difference in latitude and longitude;

Calculate the difference in latitude values between two places by x-x'Distance, longitude values differ y-y'Distance.

The Pythagorean theorem in mathematics is used to calculate the straight-line distance between two places.

Each degree of longitude is divided into 60 points.

Each minute is divided into 60 seconds. A longitude thus generally looks like this: 23°27 30 E"or longitude 23°27 30 W"。

In a more precise longitude position, seconds are expressed as fractions of minutes, e.g., 23° east longitude, but there are also degrees and its decimals: east longitude.

Sometimes the western longitude is written as a negative number:. Occasionally, however, there are people who write the Eastern Longitude as a negative number, but this is quite unconventional.

To use a simple trigonometric function, although it is a sphere, it can be straightened, that is, to draw a graticule. Then use the knowledge of high school geography: on the same meridian, the latitude difference is 1 degree, and the distance difference is 111 kilometers.

On the same parallel, the longitude differs by 1 degree, and the distance differs by 111 kilometers. Now that you can find the two right-angled sides, the Pythagorean theorem can calculate the distance.

Neither latitude nor longitude can have negative values. Longitude and latitude are all geographical coordinates and are all positions on the earth's surface**. The longitude is 0° 180° east and west, and the latitude is 0° 90° north and south, and there are no negative values.

Therefore, it is impossible to have longitude and latitude values such as -31° and -121°. However, the letters that indicate the direction after the latitude and longitude can be intermodulated, such as 30°S becomes 30°N, and 65°E becomes 65°W. The result of the north-south intermodulation of latitude values is simpler, indicating that the latitude values are the same and the northern and southern hemispheres are reversed.

The results of the east-west intermodulation of longitude values are slightly more complicated, and the intermodulation may not indicate the opposite of the east-west hemisphere. Because the eastern and western hemispheres are not divided by 0° meridian and 180° meridian, it depends on the specific longitude value to determine.

Summary. Dear, when writing longitude, you only need to write the value of longitude, you don't need to write longitude and latitude. Longitude is the angle between a point on the Earth's surface and the prime meridian, usually expressed in degrees (°). For example, Beijing is located in the east longitude, so it can be simply written.

Pro, when writing longitude, only the value of longitude needs to be written, and there is no need to write longitude and latitude. Longitude is the angle between a simple comma on the Earth's surface and the prime meridian, usually expressed in degrees (°). For example, if Beijing is located in the east longitude, it can be simply written.

1.Longitude and latitude are both parameters in a geographic coordinate system, with longitude referring to the angle from the prime meridian to the east or west, and latitude to the north or south of the equator. 2.

In order to locate a location more precisely, it is sometimes necessary to give latitude and longitude at the same time, so it is necessary to add the corresponding symbol between longitude and latitude, such as n (north latitude) or s (south latitude), e (east longitude) or w (west longitude). For example, the full geographic coordinates for Beijing are , . 3.

Longitude can also be expressed in minutes ( ) and seconds ( ), representing 116 degrees 24 minutes and 24 seconds east longitude.

The east-west meridian is a vertical line on the map. On a globe, a pair of meridians (e.g., 0° and 180°) form a meridian.

The north-south latitude is a horizontal line on the map.

The Eastern and Western Hemispheres are judged on the following terms: The range of the Eastern Hemisphere is from 20°W (20 degrees west longitude) to 160°E (160 degrees east longitude).

Judging the east-west meridian on the map: first find the zero degree meridian, left west and right east; If it's a one hundred and eighty degrees of longitude, then"Right, west, left, east"。

To the west of the zero degree meridian, the longitude value (west longitude) increases westward and decreases eastward. The same goes for the other side.

Zero meridian (prime meridian): passes through the original site of the Greenwich (Greenwich) Observatory in London, England.

The northern and southern hemispheres look at the equator. Up north and down south.

Looking at the known conditions, this needs to be analyzed on a case-by-case basis. If there are no conditions, it will default to the up-north-down south-down on the map.

W is west, west. e is east, east. s is for south, south.

n is north, north. Generally, the map will give a direction as a reference, from which to determine other directions. Hemispheres also generally give the South Pole (s) as the North Pole (n).

Anyway, it's all the rules of going up north and going down, and the point is to see the reference. For example, it is seen over the North Pole and above the South Pole. We are familiar with the northern hemisphere as a reference, and when we encounter a map of the southern hemisphere, we think the other way around.

The eastern and western hemispheres are bounded by 160°E and 20°W.

If you want to judge the east-west meridian, the stupidest way is to find the prime meridian and the north pole, and then look down from the sky above the north pole, the prime meridian turns clockwise 180°, both are west longitude. The counterclockwise 180° is east longitude.

W is West, E is East, S is South, and N is North. The warp is vertical, a warp is only a semicircle, the weft is horizontal, and the daily warp is a circle. The northern and southern hemispheres are bounded by 20° west longitude and 160° Tokyo.

East of 20°W longitude to 160° west of Tokyo is the Eastern Hemisphere, and vice versa is the Western Hemisphere. North of the equator is the Northern Hemisphere, and south of the equator is the Southern Hemisphere. Remember that the approximate latitude of Beijing is (40°N, 116°E), that is, Beijing is the northern hemisphere and the eastern hemisphere.

There is a Greenwich Royal Observatory in London, England, and the meridian that passes through this observatory is called the prime meridian, which is the zero degree meridian. To the east is the east longitude, and to the west is the west longitude.

East of 20 degrees west longitude, west of 160 degrees east longitude is the eastern hemisphere, and the other half is the western hemisphere.

e is east, which is used to represent east longitude; W is west, which is used to represent west longitude.

North of the equator is the Northern Hemisphere, and n is North, which is used to represent northern latitude;

South of the equator is the Southern Hemisphere, and S is South, which is used to represent the southern latitudes.

The dividing line between the eastern and western hemispheres: 20 west and 160 east longitude, you know that China is an eastern country, in the eastern hemisphere, then China is between 20-0 west and 60 east longitude. The United States is a Western country, and in the Western Hemisphere (economically it is not divided into Eastern and Western countries), then the United States is between 20-180 W and 160 E longitude.

The dividing line between the northern and southern hemispheres is the equator, which is the 0 degree parallel.

The east-west latitude and longitude is from the prime meridian (0° meridian), and his right side is the east longitude and the left is the west path.

w(west) e(east)s(south)n(north).

The method of distinguishing between the eastern and western hemispheres: "big is west, small is east", that is, less than 20 degrees west longitude and 160 degrees east longitude in the eastern hemisphere; Greater than 20 degrees west longitude and 160 degrees east longitude in the Western Hemisphere.

The distinction between the northern and southern hemispheres: the one with n is the northern hemisphere, and the one with s is the southern hemisphere.

The dividing line between the eastern and western hemispheres is "20 west longitude, 160 east longitude", in fact, remember these southeast and northwest, it is a very simple way, you draw a cross, up and down the north, down the south, left west, right east, and then correspondingly, up n and down s, left e right w, draw a few more slowly know how to remember.

20W to 160E is the Eastern Hemisphere, and 160E to 20W is the Western Hemisphere. The Eastern and Western Hemispheres can be judged based on the direction of the Earth's rotation and the direction of the Sun's rotation. In many cases, the north-south direction is judged based on the calculation of time, and it is generally necessary to know that the day and night of the two solstices are different in the northern and southern hemispheres.

And then there's the geographic information. I don't know if you understand it or not, there is a better topic to talk about.

Eastern Hemisphere: East of longitude 20°W and west of longitude 160°E Western Hemisphere: West of longitude 20°W, east of longitude 160°E East north of the equator for the Northern Hemisphere, south of the equator for the Southern Hemisphere.

North nw west east e south s

East of 20°W longitude, 160° - 20° west of 160°E East HemisphereThe Western Hemisphere is the other half.

s is the meaning of southern Germany, there is no s in the northern hemisphere, only n north latitude is s in the southern hemisphere, for example, China is the northern hemisphere, Beijing is 40 ° n is 40 ° north latitude.

Summary. From the equator to the north, it is 20 degrees N, 40 degrees N, and 60 degrees N Geography [Map] North latitude (n) and south latitude (S) are marked in the map, and the latitude of each latitude line is filled.

Hello. Well, good, thanks.

Send the ** over.

To the south, it is 20 degrees s, 40 degrees s, and 60 degrees s

The interval between is 20 degrees.

a Diagram of the East and West Hemispheres.

The longitude of point A is 85°e latitude is 20°s The longitude of point B is 170°e The latitude is 44°n The dividing line between the eastern and western hemispheres is 160° east longitude and 20° west longitude

East of 20°W longitude, west of 160°E is the Eastern Hemisphere, and vice versa is the Western Hemisphere.

The judgment of latitude and longitude is based on the judgment method of going up north and down south.

In a, the degree increases the further south you go, and this happens only in the southern hemisphere.

The longitude is judged according to the left-east-right-West German method, and in B, the longitude increases further east, which only appears in the east longitude range, and then it is extended that this place is 170° east longitude.

According to the different division criteria of the eastern and western hemispheres, it is deduced that the hemisphere to which the place belongs!

Figure Southwest, Figure B East.

(1) Diagram A is located in the Eastern Hemisphere of the Eastern and Western Hemispheres, and the Southern Hemisphere of the Northern and Southern Hemispheres, Diagram B.

Located in the Eastern Hemisphere of the Eastern Hemisphere, the Northern Hemisphere of the Northern Hemisphere

2) The longitude of point A is 85° east longitude and the latitude is 20° south latitude

The longitude of point B is 170° east and the latitude is 44° north

It's mainly about where they go.

(1) South-east.

North (2) Point A is 85° east longitude and 20° south latitude

Point B is 170° east longitude and 44° north latitude

To illustrate the process!!

Look at the direction of this type of question, it is up to the north, down to the south, left to the west, and the right to the east.

1) Diagram A is located in the east.

The eastern hemisphere of the western hemisphere, the southern hemisphere of the northern and southern hemispheres, the western hemisphere of the eastern and western hemispheres, and the northern hemisphere of the northern hemisphere

The increase in longitude from left to right in Figure A proves that it is east longitude, and 85 degrees east longitude is located in the Eastern Hemisphere, and in Figure B, 170 degrees east longitude is located in the Western Hemisphere.

Diagram A decreases the latitude from bottom to top, which is 20 degrees south latitude, in.

The Southern Hemisphere, while the B diagram is enlarged from bottom to top, is 44 degrees north latitude, located in the Northern Hemisphere.

The coil that runs east-west and orbits the Earth is the parallel, and the equator is the largest coil of latitude (also called the 0-degree parallel): north is the Northern Hemisphere, which is represented by n; To the south is the Southern Hemisphere, S denotes. The half-coil in the north-south direction and perpendicular to the parallels is the longitude, the prime meridian (also called the 0 degree meridian):

East is called east longitude, and e is described; West is called West Longitude, W is described; A coil formed by 160 degrees east longitude and 20 degrees west longitude is the dividing line between the eastern and western hemispheres, east of 20 degrees west longitude is the eastern hemisphere, and west is the western hemisphere.
