The distinction between latitude and longitude, how to distinguish between latitude and longitude

First of all, you need to know the North and South poles and the equator!

The meridian is a great circle around the earth, but to pass through the north and south poles, it is now recognized that the meridian that passes through the Greenwich Observatory in the United Kingdom is 0 ° longitude, and the longitude of Beijing, China is 116 ° east longitude, and we generally call the range of 20 ° west longitude and 160 ° east longitude called the eastern hemisphere, and vice versa called the western hemisphere.

The equator is a large circle that crosses the middle, and it is also the direct ray of the sun on the spring and autumn equinoxes. Then many large circles are divided parallel to the equator, and these circles are called weft coils, and the weft coils are the greater the degrees and the shorter the circumference is the higher the north and south poles, and the meridian coils are of equal length. (All hand-beaten!!) ）

The northernmost point of the earth is the North Pole, the southernmost point is the South Pole, the meridian is the line segment connecting the north and south poles, which is a semicircle, and the latitude line is a circle of vertical meridians, but the latitude and longitude line does not exist, just for the convenience of people to understand the location of various places. (I'll learn it when I get to junior high school!) ）

Just like cutting a watermelon, each knife cut vertically is equivalent to a longitude, and the horizontal cut is the latitude, the latitude line starts from the equator is 0 degrees, to the north is called the north latitude, to the north pole is 90 degrees north latitude, to the south latitude is 90 degrees south latitude, to the south pole 90 degrees south latitude, the meridian starts from Greenwich, England, turns half a circle to the east, is 0 to 180 degrees east longitude, and turns 180 degrees to the west, which is 0 to 180 degrees west longitude, which adds up to a circle of 360 degrees. You should get the idea.

The latitude is north-south and the longitude is east-west.

What is the method of determining latitude and longitude?

1.Longitude is the coil connecting the north and south poles, which is divided into the eastern and western hemispheres by 160 degrees east longitude and 20 degrees west longitude, increasing from west to east to east longitude, and vice versa is west longitude.

The latitude is very horizontal, the equator is 0 latitude, with the equator as the axis of symmetry, the closer to the two poles, the greater the number, the higher the latitude, 0 30 is the low latitude, 30 60 is the middle latitude, 60 90 is the high latitude.

2.Latitude degree range, 0-90...Longitude degree range, 0-180 degrees.

The 0 degree latitude is the equator. The 0 degree meridian is the prime meridian. The meridian that passes through the former site of the Greenwich Observatory in the United Kingdom.

The latitude gradually increases from the equator to the south and north. The longitude gradually increases from 0 degrees of meridian to east and west.

The dividing line between the northern and southern hemispheres is the equator. The dividing line between the eastern and western hemispheres is 160°E and 20°W.

3.Most coordinate data expressed in latitude and longitude consists of two sets of numbers, generally speaking, the first set of numbers is longitude, and the last set of numbers is latitude.

The longitude is generally from 0° to 180°, divided into east longitude and west longitude, east longitude is represented by the prefix e (east) in the coordinates, and west longitude is represented by the prefix w (west) in the coordinates; The latitude is from 0° to 90°, divided into north latitude and south latitude, the north latitude is represented by the prefix n (noth) in the coordinates, and the southern latitude is represented by the prefix s (south) in the coordinates.

First, the direction is different.

2. Latitude: refers to the line between a certain point and the center of the earth's sphere and the angle of the line formed by the earth's equatorial plane, the geodetic latitude refers to the angle between the normal of the ground and the equatorial plane, and the astronomical latitude refers to the angle between the plumb line and the equatorial plane.

Second, the characteristics are different.

1. Longitude: The longitude of other places on the earth is to the east to 180° or to the west to 180°. 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.

2. Latitude: The arc distance between any point on the meridian and the equator is called latitude. It is one of the geographic coordinates and plays the role of ordinate in geographic coordinates, which can be used to determine and describe any place or location on the earth's surface.

There are several types of latitudes: geographical, astronomical, and geocentric, and the difference between these latitudes is not large.

3. The degree of relevance is different.

1. Longitude: The east longitude to the east is 180 degrees; To the west of it is the west longitude, which is 180 degrees Celsius. Because the earth is round, the longitude of 180 degrees east and 180 degrees west longitude are the same meridian.

The 180-degree longitude is designated as the "International Date Line".

2. Latitude: The south of the equator is called the southern latitude, and the north of the equator is called the north latitude. The North Pole is 90 degrees north latitude, and the South Pole is 90 degrees south latitude.

The high and low latitudes also mark the hot and cold climate, such as no winter in the equatorial and low latitudes, no summer in the poles and high latitudes, and four distinct seasons in the middle latitudes.

Main feature: The arc distance between any point on the meridian and the equator is called latitude. It is one of the geographic coordinates and plays the role of ordinate in geographic coordinates, which can be used to determine and describe any place or location on the earth's surface.

There are several types of latitudes: geographical, astronomical, and geocentric, and the difference between these latitudes is not large.

In most cases, latitude refers to geographic latitude (i.e., the latitude used to draw the map). Geographic latitude is the length of the arc on the ground corresponding to the angle of the Earth's sphere. Geographic latitude treats the Earth as an ellipsoid, i.e., the angle between the normal of the ellipsoidal surface (slightly different from the plumb line) and the plane of the equator.

It is usually expressed in degrees, minutes, and seconds.

The distinction between latitude and longitude is as follows:

The longitude of the prime meridian is 0°, and the longitude of the rest of the earth is 180° east or 180° west.

East longitude 180° is west longitude 180°, which is about the same as the international date line, and the dates on both sides of the international date line are one day apart. Longitude is the dihedral angle formed by the meridian plane and the prime meridian plane passing through a certain place. The longitude east of the prime meridian is called east longitude, and the longitude west of the prime meridian is called west longitude.

East longitude is represented by an "e" and west longitude is represented by a "w".

Latitude: North latitude is positive, southern latitude is negative. Latitude refers to the normal of a point on the ellipsoidal surface, and the angle between the normal of the point and the plane of the equator is between 0 and 90 degrees.

The latitude of the 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.

Areas with latitude values between 0 and 30 degrees are called low latitudes; Areas with latitude values between 30 and 60 degrees are called mid-latitudes; Areas with latitude values between 60 and 90 degrees are called high latitudes. The equator, Tropic of Capricorn, Tropic of Capricorn, Antarctic Circle, and Arctic Circle are special parallels.

The parallel, like the meridian, is an auxiliary line assumed by humans for the convenience of measurement, and is defined as the trajectory formed by the rotation of the earth at a point on the earth's surface. Any one of the wefts is round and parallel to each other. Bumper.

Parallel: The length is the cosine of the circumference of the equator multiplied by the latitude of the parallel, so the equator is the longest, and the farther away from the equator is the latitude, the shorter the circumference, and it shrinks to 0 at the poles. From the equator to the north and south, each 90°, is called the north and south latitudes, which are denoted by "n" and "s", respectively.

The longitude is divided into east and west, the guide is north, and the latitude is divided into north and south, referring to east and west.

Longitude: Also known as meridian, like the latitude line, it is an auxiliary line hypothesized 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.

Longitude and latitude is the combined name of longitude and latitude to form a coordinate system, called the geographic coordinate system, which is a spherical coordinate system that uses the spherical surface of three-dimensional space to define the space on the earth, and can mark any position on the earth.

Longitude

Longitude, a geographical term, generally refers to the abscissa of the spherical coordinate system, specifically the degree to the east or west of a north-south alignment of a place on the earth called the prime meridian. According to international regulations, the longitude at the original site of the Greenwich Observatory in London, the capital of the United Kingdom, is set at 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. Longitude, as a basis of geography, is the basic theory for understanding the rotation of the earth and the geographical division of regions.

Latitude

Latitude can be divided into astronomical latitude, geodetic latitude, and geocentric latitude. Geocentric latitude refers to the line between a point and the earth's sphere and the angle of the earth's equatorial plane, geodetic latitude refers to the angle between the normal of the ground and the equatorial plane, and astronomical latitude refers to the angle between the plumb line direction of the place and the equatorial plane. What we usually call latitude is geodetic latitude.

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.

When the earth rotates, there is a fixed point in the north and south called the south pole and the north pole. The imaginary line that connects the north and south poles through the center of the earth is the Earth's axis, the Earth's axis of rotation. The equator is the circumferential line that intersects the Earth's surface through an imaginary plane that passes through the Earth's center and is perpendicular to the Earth's axis.

It divides the earth into two hemispheres, the north and the south. The equator and the Arctic and Arctic control points are used to determine the latitude and longitude (geographic coordinates) of each place. The meridian is a circumferential line that connects the poles and is perpendicular to the equator, and the latitude is a circumferential line parallel to the equator.

Latitude is the zero degree line with the equator as the zero degree, and the northern and southern hemispheres are divided into 90 degrees. Latitude and longitude can be easily calibrated to any position on the earth.
