Are the latitude and longitude coordinates of the same point the same in different coordinate system

The same point is in different coordinate systems.

The coordinates under are generally different.

In question: Since it is "latitude and longitude.

coordinates" will no longer exist "different coordinate systems";

If you use "different coordinate systems", there must be a coordinate system that is not "latitude and longitude coordinates".

The "graticule" that is now commonly used is also a coordinate system.

Latitude and longitude. There are generally three types: astronomical latitude and longitude; latitude and longitude of the earth; Latitude and longitude of the center of the earth. What we usually refer to is the latitude and longitude of the earth.

Different coordinate systems.

The assumed spheroids have different parameters, so their longitude and latitude plexus clarity values are different. Only if there is a destruction or the same coordinate system, the latitude and longitude are unique.

First of all, it is not the same location, although the Beijing 54 coordinate system and the WGS84 coordinate system belong to the geodetic coordinate system, the ellipsoid size, positioning, and orientation are different.

In addition, the latitude and longitude of the earth and the latitude and longitude of the astronomical are different, but they can be converted to each other.

(1) The height of the sun at noon on the same day is the same, the time of sunrise and sunset, and the length of day and night are the same;

2) the linear velocity of the Earth's rotation is the same when the terrain is not taken into account;

The meridians and parallels were drawn on globes and maps in order to determine the position and direction on the earth, and there were no latitude and longitude lines on the ground. However, it is not difficult to see the meridian of the place: stand a bamboo pole on the ground, and when the sun rises at noon, the shadow of the bamboo pole is the meridian of the place.

Because the meridian indicates the north-south direction, the meridian is also called the meridian.

1) It is possible that this point is located in a different zone under the national 2000 coordinate system, for example, this point can be in both the coordinate system of the 18th degree zone and the coordinate system of the 19th degree zone.

2) It is also possible that although they are all national 2000 coordinate systems, the **meridian L0 of the projection and the elevation h0 of the projection surface are different, resulting in the XY coordinates calculated by Gaussian forward and backward of the final longitude and latitude BL.

The warp and weft are intertwined to form a graticule, how to determine the latitude and longitude of a place in the graticule?

The longitude is divided into east longitude and west longitude, and the east longitude from 0° longitude to 180° is east longitude, which is represented by the letter E. From 0° longitude to 180° west longitude, the letter w indicates that the longitude is larger and larger east longitude, and west longitude is larger and larger west.

Latitude is divided into north and south latitudes, north of the equator is the north latitude, represented by the letter n, the number of degrees to the north is increasing, and the north pole is 90 degrees north latitude. South of the equator is the southern latitude, denoted by the letter s, and the number of degrees to the south is increasing, and the south pole is 90° south latitude.

We use the four directions of east, south, west, and north to represent this law of change in latitude and longitude, if it becomes larger to the east, it is the east longitude, the west becomes the west longitude, the north becomes the north latitude, and the south becomes the south latitude. According to this law of change, the latitude and longitude of a certain place can be determined in the graticule.

If it is a graticule diagram centered on the polar regions, we can first judge whether the map is centered on the North Pole or the South Pole according to the direction of rotation of the earth, and then judge the latitude and longitude. Conversely, we can also judge the direction of rotation according to the north and south poles, and then interpret the longitude.

At the same time, it is necessary to write the latitude and longitude correctly. For example, if the longitude of a place is 110° east longitude and the latitude is 35° north latitude, you can directly write it as: "35° north latitude, 110° east longitude" or write it as:

35°N, 110°E ", generally latitude first, longitude behind, separated by ","or", "in the middle. When using letters, take care to capitalize the letters and write them after the degrees.

Well, the latitude is horizontal, and the longitude is vertical.

If you judge that it is the western longitude, you just have to look at it.

Longitude decreases from west to east.

East longitude is. Longitude west to east.

Growing. Latitude; There is a 0-degree equatorial murmur.

North of the equator is the Northern Hemisphere, and conversely, the Southern Hemisphere.

The addition of latitude and longitude is one place that you can read.

The spherical distance is:

arccos (sinw1*sinw2+cosw1*cosw2*cosj difference)*pi*r 180 degrees.

Among them, W1 and W2 are the latitudes of the two places, J difference is the longitude difference between the two places, and Pi is the circumferential rate of the circular nucleus (i.e., the radius of the earth; The J difference is the positive value of the old one, and W1 and W2 are positive at the north latitude and negative at the south latitude.

Summary. The formula between spherical coordinates (x, y, z) and latitude and longitude is :

y/x = tanβ

z/√(x2+y2+z2) =sinα

How to use latitude and longitude to calculate coordinatesHow to convert the latitude and longitude of a place to the coordinates of a certain place.

The formula between spherical coordinates (x, y, z) and latitude and longitude is: y x = tan z (x2+y2+z2) = sin

The pole is 90 degrees Longitude is divided horizontally, and the earth knows that a circle is divided into 360 degrees, and the east and west longitudes are 180 degrees each, but it should be noted that the starting point of the east and west 0 longitude is the same, and 180 degrees also coincide!

Critical spherical coordinates are not known.

I don't know, I can't count.

If you only know the latitude and longitude, you can't calculate it.

Taking the conversion of latitude and longitude into plane XY coordinates as an example, the conversion algorithm is used. Method of converting latitude and longitude to coordinates: The coordinates on the sphere (latitude and longitude) are converted into projected cylindrical coordinates by trigonometric functions.

Convert to coordinates in map squares. China stipulates that the longitudinal axis of each band moves 500 kilometers westward, that is, all y values are added by 500 kilometers, and the band number of each band is added before the coordinate value. Taking 18 bands as an example, after moving westward, the original coordinate value is y=243, m,y=744,, and the total coordinate of the added band number is y=.

Longitude and latitude are a combination of latitude and longitude to form a coordinate system. Longitude is the degree in which a point on Earth goes east or west from the north-south line called the prime meridian. Latitude is the line-to-surface angle between a point and the center of the Earth and the equatorial plane of the Earth, with values between 0 and 90 degrees.

Longitude and latitude are a combination of latitude and longitude to form a coordinate system. Also known as the Geographic Coordinate System. It is a spherical coordinate system that uses a sphere of three-dimensional space to define space on Earth and can mark any location on Earth.

This is also necessary to know XY.
