What does the latitude and longitude mean by grabbing the red envelope with one click

Is the latitude and longitude set for positioning?

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

Positioning, the latitude and longitude of your current location.

It's analog positioning. It's all going to be slowly.

Longitude is the vertical axis of the confirmed region, and latitude is the horizontal axis of the confirmed region, similar to the coordinate system of mathematics, where two values confirm a point. The longitude is a semicircle, the latitude is a circle, and the value of one longitude and the value of one latitude can find a corresponding position on the earth, and the latitude and longitude can be sent when calling for help from the world.

In special cases, reporting your latitude and longitude can tell you exactly where you are.

Isn't it just the location, you will understand it when you go to junior high school.

The tool used to locate you can see that you are in Shanghai.

Longitude indicates north and south, and latitude indicates east and west.

Coordinates like a function can accurately represent the position of any place on the earth, and this position can be quickly confirmed by navigation satellites. You said that the longitude of Taipei and Shanghai is about the same vertical line, but the latitude difference is much.

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.

Each degree of latitude is equivalent to approximately 111 kilometers, but the distance of each degree of longitude varies from 0 kilometers to 111 kilometers. Its distance varies with latitude and is equal to 111 kilometers multiplied by the cosine of latitude. However, this distance is not the shortest distance between two points separated by one longitude, the shortest distance is the distance of the arc connecting the two points in the great circle, which is a little smaller than the distance calculated above.

Latitude refers to the line between a point and the center of the Earth's sphere and the angle of the Earth's equatorial plane, and its value is between 0 and 90 degrees. The latitude of a point located north of the equator is called north latitude and is denoted as n, and the latitude of a point located south of the equator is called southern latitude and 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, and areas with latitude values between 60 and 90 degrees are called high latitudes.

On the map and the globe, we can see thin lines, horizontal and vertical, much like the squares on a chessboard, which are the meridians and latitudes. Based on these latitude and longitude lines, the position and direction of any place on the ground can be accurately determined.

How are these warp and weft lines determined? The earth is constantly rotating around the earth's axis (the earth's axis is an imaginary line passing through the earth's north and south poles and the center of the earth), and a large circle perpendicular to the earth's axis is drawn in the middle of the earth, so that each point on the circle is equal to the distance between the north and south poles, and this circle is called the "equator". On the north and south sides of the equator, many circles parallel to the equator are drawn, which are called "latitude circles"; The segments of the lines that make up these circles are called the wefts.

We set the equator as zero degrees of latitude, 90 degrees to the south and 90 degrees to the north, and the one south of the equator is called the south latitude, and the one 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.

Longitude refers to the abscissa of a spherical coordinate system. It is expressed by the angular distance of the auxiliary circle where the point on the sphere is located relative to the auxiliary circle where the coordinate origin is located. Usually refers specifically to the longitude of a geographic coordinate.

In order to distinguish each region of the earth, people marked the meridians with degrees, which is called longitude.

What latitude and longitude mean, you know, let's learn together.

Measured from the equator northward.

north latitude" (n); The southward measure is "southern latitude zhi" (daos). by 0° to 90°.

Calculated from the 0° meridian, the east and west of the plate are divided.

180°, 180° east belongs to east longitude, and it is customary to use "e" as a code, and 180° to the west belongs to west longitude, and it is customary to use "w" as a code. The 180° east longitude and the 180° west longitude coincide on a single meridian, which is the 180° meridian.

East longitude e, west longitude w, south latitude s, north latitude n

In navigation, longitude and latitude are usually represented by Greek letters, as follows:

Longitude is pronounced --- lamda lambda.

Latitude pronunciation---phi 服爱.

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.

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. When we say latitude, we usually mean the latitude of the earth.

1. The main characteristics of 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.

2. Latitude 1 second length:

The total length of the Earth's meridian is about 40,008 km.

Average: 1 degree of latitude = about 111 km, 1 minute of latitude = approximately, 1 second of latitude = approximately.

3. Latitude range:

Low latitude range: between 30° north and south latitudes;

Mid-latitude range: between 30°N and 60°N and between 30°S and 60°S;

High latitude range: north of 60°N and south of 60°S.

East longitude is positive, west longitude is negative. 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.

Latitude refers to the normal line of a point on the ellipsoidal surface, and the angle between the normal of the point and the plane of the equator, the value of which 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.

Longitude and latitude are all virtual dotted lines on the earth, longitude has east longitude and west longitude, so it is vertical, latitude is horizontal, with longitude and latitude you can locate a point on the earth.

Longitude indicates north-south, longitudinal.

Latitude indicates east-west, transverse.

Up and down longitude, left and right latitude.

What is Warp? What are the features?

A warp refers to a thread that connects two poles. Each meridian is a semicircle, and two opposing meridians of equal length (measurement) form a meridian coil, dividing the globe into two halves, and the distance between any two meridians (measurement) is not equal.

The prime meridian is 0° and passes through the Greenwich Observatory in the United Kingdom.

What is Longitude? How is the East and West meridians divided?

The angle between the plane of the prime meridian and the plane of the local meridian is the longitude. From the prime meridian to the east to 180° for the east longitude, with"e"Denote; 180° west from the prime meridian is the west longitude"w"Denote;

What is Equator? What is Weft? What are the features?

The line that is equal to the poles and perpendicular to the meridian is the equator and has a degree of 0*The lines parallel to the equator are parallels, the coils of latitude are circles, and each parallel is of unequal length, (measured) the equator is the longest (measured).

Decreasing (measured) from the equator to the poles, there are two parallels of the same degree, symmetrically distributed on both sides of the equator. The equator divides the globe into two halves, with any two parallels at an equal distance (measurement).Each parallel is perpendicular to the equator (measured).

How are southern and northern latitudes divided?
