I want to convert latitude and longitude to local coordinates, or vice versa from local coordinates

This can be implemented with COORD software. In the calculation of four parameters, first calculate a four-parameter through blh coordinates and xy coordinates (four-parameter does not care about elevation, no elevation can be calculated), if the number of parameters is calculated, you need to enter the source coordinate for xy, you can use the outside button to convert bl from wgs84 geodetic coordinates to xy, and then find the parameters. Finally, on the initial interface, select "Four Parameters", ellipsoid (if you don't know, choose 54 directly, because 54 is relatively small and can be ignored in a small range), and then directly convert XY to BL through file conversion.

There are some problems with the content you provided, 1, the b, l of a point is known, and the elevation is not known. and the corresponding local coordinates, so what more do you want? Does it mean that you only know the above information of some common points, and you want to find the coordinates of other points based on this?

2. Are the local coordinates you mentioned under a coordinate system other than BJ53 and XA80? Or are you not sure which system it belongs to?

3. If it is one of these two, then the handheld GPS can be converted to X, Y and B, L

4. The elevation of latitude and longitude and the elevation of xy are based on a certain plane (such as the sea level of the Yellow Sea in that year, etc.), or a certain standard.

b, l, the point corresponding to xy is the same point on the earth, like the datum of elevation, the elevation is the same, refer to 4

5. There are many such software on the computer, such as domestic GIS software. The question is what system are the coordinates of your place.

With mapgis, the accuracy of the common point method of coordinate conversion is still high.

1. Determine the projection band: the projection method adopts 6° bands on the scale bar 10,000-1:500,000 figures, and uses 3° bands for the scale bar 1:10,000 and more than 1:10,000 figures.

Second, the conversion is to use trigonometric functions to convert the coordinates (latitude and longitude) on the sphere into the cylindrical coordinates of the projection. Convert to map square coordinates. China stipulates that the ordinate axis of each belt will be moved westward by 500 kilometers, that is, all y values will be added by 500 kilometers, and the coordinate value will be preceded by the band number of each band to take 18 belts as an example, the original coordinate value is y=, after moving westward, it is y=, and the general coordinates with the band number are y=.

3. 6° zoning method and 3° zoning method.

Band method: from Greenwich zero degree longitude, every 6 ° is divided into a projection band, the world is divided into a total of 60 projection bands, the eastern hemisphere from 0 ° to 6 ° east longitude is the first zone, ** meridian is 3 °, and so on, the projection band number is 1-30. The calculation formula for the projection code n and ** longitude l0 is:

l0=(6n-3)°;The western hemisphere projection zone is calculated from 180° to 0°, numbered 31-60, and the calculation formula of the projection code n and ** longitude l0 is l0=360-(6n-3)°.

Zone method: from 1 ° 30 east longitude, every 3 ° is a belt, the world is divided into 120 projection belts, there are 60 projection bands in the eastern hemisphere, numbered 1-60, each belt ** meridian calculation formula: l0 = 3 ° n, ** meridian is °

180°。There are 60 projection bands in the Western Hemisphere, numbered 1-60, and the calculation formula of ** meridian in each belt is: l0 = 360 °-3 °N, ** meridian is west longitude °.

Fourth, before conversion, we must first figure out what system this coordinate is. In addition, when using the software conversion, it is necessary to set the projection instead of directly entering the above coordinates.

Fifth, refer to the above steps to solve the problem, I can only share with you the method, it is better to teach a person to fish than to teach a person to fish, I hope you not only understand this problem, but I hope you can understand how it is transformed.

I want to convert the coordinates of the independent zone of the Yangquan mining area into the CGCS2000 latitude and longitude coordinates, and how do I determine whether the Yangquan mining area is Beijing 54 or Xi'an 80 during the conversion process

Dear, you need to know the specific geographical location of Yangquan mining area, and determine whether it is in Xi'an 80 or Beijing 54 coordinate system, secondly, you need to find a map about Yangquan mining area, the map will often indicate the coordinate information, from which you can determine whether the coordinate system of Yangquan mining area is Beijing 54 or Xi'an 80, and finally, according to the determined coordinate system, use the corresponding conversion tool to convert the coordinates to CGCS2000 latitude and longitude coordinates. <>

Summary. Hello <>

Converting XY coordinates to latitude and longitude coordinates needs to take into account the differences in the shape and coordinate system of the Earth. The WGS84 coordinate system is usually used to represent the coordinate position of the earth's surface, so you need to convert the XY coordinates to the coordinate values in the WGS84 coordinate system first, and then further convert them to latitude and longitude coordinates. The specific conversion process can be achieved by using professional map coordinate conversion tools or APIs, which generally provide relevant conversion functions or interfaces, and the corresponding latitude and longitude coordinates can be obtained by inputting the numerical value of XY coordinates and the corresponding coordinate system information.

It should be noted that when performing coordinate conversion, it is necessary to ensure that the input coordinate system and the output coordinate system information are accurate, otherwise the conversion result will generally be incorrect.

Hello <>

Converting XY coordinates to latitude and longitude coordinates needs to take into account the differences in the shape and coordinate system of the Earth. The WGS84 coordinate system is often used to represent the coordinates on the earth's surface, so you need to convert the XY coordinates to the coordinate values under the WGS84 coordinate system, and then further convert them to latitude and longitude coordinates. The specific conversion process can be achieved by using professional map coordinate conversion tools or APIs, which generally provide relevant conversion functions or interfaces, and the corresponding latitude and longitude coordinates can be obtained by inputting the numerical value of XY coordinates and the corresponding coordinate system information.

What are the x y latitude and longitude coordinates.

Hello <>

x=,y=oh.

x-coordinate position y-coordinate location wgs84 what is the latitude and longitude.

Hello <>

According to the coordinates provided, Brother Heng is missing to do wgs84 longitude and latitude is north latitude and east longitude.

There are two ways to convert latitude and longitude from coordinates:

1. Two-dimensional conversion.

The two-dimensional conversion method is to convert planar coordinates (east and north) from one coordinate system to another. Elevation parameters are not calculated at the time of conversion. The conversion method requires the determination of 4 parameters (2 translational parameters to the east and north, 1 rotation parameter and 1 scale factor).

If you want to keep the GPS measurements independent and have information projected on the local map, then the 3D conversion method is most suitable.

2. Three-dimensional conversion.

The basic operation steps of this method are to use the common point, that is, the point with both WGS84 Cartesian coordinates and Cartesian coordinates of the local coordinates, generally need more than 3 coincident points, and calculate them through the Bursha model (or other models) to obtain the translation parameters, rotation parameters and scale factors converted from one system to another.

Classification of coordinate transformations

1. Geodetic coordinates (BLH) versus plane Cartesian coordinates (XYZ).

The conventional conversion should first determine the conversion parameters, that is, the ellipsoid parameter, the zoning criterion (3 degrees, 6 degrees) and the longitude of the **meridian. The ellipsoid parameter refers to what kind of ellipsoid datum is used in the Cartesian coordinate system of the dressing plane, which corresponds to different major and minor axes and flat ratios. To draw to the Cartesian coordinate system, you can write it as (x+z*acos, y+z*asin)a, as a parameter.

2. Mutual conversion of Beijing 54 national 80 and WGS84 coordinate systems.

A geocentric coordinate system adopted internationally. The origin of the coordinates is the center of mass of the earth, the Z-axis of the Cartesian coordinate system of the geocentric space points to the direction of the Pole of the Earth (CTP) defined by BIH (International Time), the X-axis points to the intersection of the zero meridian of BIH and the equator of the CTP, and the Y-axis is perpendicular to the Z-axis and X-axis of the macro-missing lift to form a right-handed coordinate system, which is called the 1984 World Geodetic Coordinate System.

3. Conversion of any two spatial coordinate systems.

Since the survey coordinate system and the construction coordinate system use different standards, it is necessary to know at least 3 coincident points (i.e., points where the coordinates are known in both coordinate systems) in order to make an accurate conversion. The Bursha model is used to solve the problem.

To convert latitude and longitude to local coordinates, you can use geographic information system (GIS) software or a map service. Here are the steps to convert using ArcGIS Pro software:

1.Open the ArcGIS Pro software and load the map.

3.Tap the tool to open the conversion interface.

4.In Transform the Boundary Excavation Surface, enter the values for longitude and latitude.

5.In the tool interface, select the appropriate coordinate system or projection system to convert latitude and longitude to local coordinates.

6.Click the "Convert" button and wait for the conversion to finish.

7.When the conversion is complete, the local coordinates are displayed in the output.

8.You can save local coordinates as a file or apply them to other geoanalysis tasks.

Hello dear, I'm Teacher Donna, I'm happy to answer for you. The specific method of converting XY coordinates to latitude and longitude coordinates is as follows:1

Determine the latitude and longitude coordinates (0, 0) of the origin of the xy coordinate system o(x0,y0) on the earth. 2.Calculate the position vector of the point p(x,y) in the xy coordinate system Transform the coordinates of the op and translate it to the origin o'and rotate the coordinate axis so that the x of the new coordinate system'The axis points east, y'The axis points north.

4.In the new coordinate system, the coordinates of point p are (x',y')。5.

x'The value is assigned to the longitude, and the positive and negative values are divided into east and west longitude. 6. y'The value is assigned to the latitude, and the positive and negative values are divided into north and south latitudes.

7.Then the latitude and longitude coordinates of the point Zen closure p are ( ,8.).Pay attention to the conversion of coordinate units, the xy coordinate unit can be a meter, and the latitude and longitude are unified as degrees.

Conversion formula: 0 + x' /kφ =0 + y'k, where k is the coordinate unit conversion factor.

Converting local coordinates to required latitude and longitude coordinates requires the following steps:1Parameters for determining the local coordinate system:

The parameters of the local coordinate system include information such as origin, axis direction, and units. These parameters are usually provided by the local** or relevant authorities. 2.

Convert local coordinates to Cartesian coordinates: Converts the local coordinate system to a Cartesian coordinate system based on the parameters of the Cathic implicit coordinate system. The Cartesian coordinate system is a common planar coordinate system consisting of an x-axis and a y-axis.

3.Convert Cartesian coordinates to latitude and longitude coordinates: Convert the Cartesian coordinate system to a latitude and longitude coordinate system through mathematical calculations.

The latitude and longitude coordinate system consists of latitude and longitude and is used to allow Sun Da to represent the position on the earth's surface. The specific conversion method depends on the vertical conversion formula between the local coordinate system and the latitude and longitude coordinate system. In some places, local coordinates can be converted directly to latitude and longitude coordinates using a simple conversion formula.

However, in some cases, it may be necessary to use a more complex transformation model, such as a Bursa model or a polynomial-fitting model, to obtain more accurate transformation results. It is important to note that the conversion between the local coordinate system and the latitude and longitude coordinate system involves complex mathematical calculations and map projection methods. When converting, the data needs to be processed using specialized geographic information system (GIS) software or specialized knowledge of mathematics and cartography.
