Introduction to Geodetic Coordinate Conversion Software


Software and hardware environment for running the software system:

The software system is divided into network version and stand-alone version.

1,Network version

It is also divided into Internet version and LAN version. The Internet version is suitable for anyone to use online at any place, and the LAN version is suitable for companies and units.

The user does not need to install the network version of the software, but only needs to browse online.

The Internet version of this software system is suitable for a variety of mainstream browsers, preferably equivalent to IE10.0Above version. Computers, mobile phones, virtual machines and total stations can be operated and used online without installation or uninstallation.

2,Stand-alone version

The stand-alone version is suitable for single computers and virtual machines.

Requires Intel i3 CPUOr above, minimum 2G memory hardware configuration, Windows 7 or above operating system(32Both 64-bit and 64-bit)。The installation and uninstallation are simple and clear, and the uninstallation is complete without leaving traces.

1 summary

Users of this software must be surveying and mapping professionals, or personnel related to surveying and mapping technology, or other personnel with corresponding technical qualifications.

This software system is the mutual conversion between four geodetic coordinate systems widely used in the field of national engineering construction and scientific research. These four coordinates are expressed in terms of the time of birth: 1954, 1980, 1984, and 2000.

This software system can convert plane coordinates and geodetic coordinates. Whether it is plane coordinates or geodetic coordinates, the results will give two kinds of results: plane coordinates and geodetic coordinates. For example, if the coordinate file submitted by the user is geodetic coordinates, the converted geodetic coordinates and the plane coordinates of the 3 or 6 degree zone will be given. If the coordinate file given by the user is plane coordinates, the converted geodetic coordinates and plane coordinates will also be given.

The software system adopts a unified data file format, which makes it easy for users to master.

The software system is developed with intelligent thinking, which makes the user's operation process simple and easy to complete the work task. Therefore, there are not many problems to be considered by users in the process of operation. Users only need to look at a few simple control elements on the main interface to basically operate. That is, users only need to submit the data file to get the desired conversion result after simple selection and setting.

Note: The stand-alone version retains the function of allowing users to select the number of conversion parameters.

Normally:

A pair of common points can solve 3 parameters,

Two pairs of common points can solve five parameters,

Three pairs of common points can solve seven parameters,

Three or more pairs of common points can solve 9 parameters.

However, the stand-alone version gives the number of parameters below the maximum parameter in the "Select number of parameters" combo box for user selection. For example, three pairs of common points can solve seven parameters, but also give the number of five parameters and three parameters. In addition to seven parameters, users can also choose five parameters or three parameters. At this time, the less the number of parameters, the higher the accuracy of the solution.

The network version is determined automatically according to the general situation.

The cases cited in this manual are mainly in the online version. In order to avoid repetition, the stand-alone version only introduces the instructions and necessary theoretical explanations.

2 Data file format convention

2.1 Plane coordinate data file format

(1)The basic format of data file for plane coordinates is:

Roll callNxEyH

or

Roll callNxEy

Among them,

NxIndicates that the due north direction is the positive direction of the ordinate axis, and Ey indicates that the due east direction is the positive direction of the ordinate axis, which is the measurement coordinate system.

The elevation H does not work, but it is not necessary to remove it for the convenience of users.

2.2 Geodetic data file format

(2)The basic format of data file for geodetic coordinates is:

Roll callBLH

or

Roll callBL

Among them,

BIs latitude, L is longitude, and H is geodetic height.

The geodetic height H is not included in the calculation, but can be retained in the data file.

2.3 Common point file data file format

The format of the common point coordinate data text file submitted by the user is:

Current coordinate system coordinates

=============

Target coordinate system coordinates

Note: More than one equal sign should be used(It is recommended to use more than five and less than 20 consecutive“=”Is appropriate)As a separator for the coordinates of the two coordinate systems.

The roll call of public points should be the same. If there is more than one public point, the order before and after the roll call should be consistent.

example:

P01 Nx1 Ey1 H1

P02 Nx2 Ey2 H2

===========

P01 Nx1' Ey1' H1'

P02 Nx2' Ey2' H2'

2.4 Convert parameter data file format

The order of conversion parameters is:

The three parameters are:⊿X,⊿Y,⊿Z

Five parameters are:⊿X,⊿Y,⊿Z,da,df

Seven parameters are:⊿X,⊿Y,⊿Z,ωx,ωy,ωz,m

Nine parameters are:⊿X,⊿Y,⊿Z,ωx,ωy,ωz,m,da,df

In the data file, each parameter occupies one line in this order. For example, a five-parameter data file format should be:

⊿X

⊿Y

⊿Z

da

df

A practical example of the corresponding specific parameter value is as follows:

-113.9035

-4.7058

6.8397

3.0000

0.00000000251

Click the "Help" button again to close the help.

3.2 Convert coordinates using common points


Before uploading a file, users need to click the "Browse" button to browse to the file to be uploaded, select it and open it. At this time, the full path of the file to be uploaded will be displayed in the text box on the left side of the browse button. As shown in the figure below:

(1)Convert geodetic coordinates

That is, the 1980 geodetic coordinate uploaded by the common point pair is converted into the 1984 coordinate system.

Specific operation: select the current coordinate system as 1980 and the target coordinate as 1984, select the "Upload common point coordinate file" option button and browse to the common point file, that is, browse to the 1980 coordinate system file to upload, and then click the submit button to get the 1984 coordinate system coordinates, including its plane coordinates and geodetic coordinates, as well as coordinate files in four file formats. The operation process is as follows:

Achievements display page:


From the above results display page, we can see that two kinds of coordinates are allowed to appear simultaneously in the common point coordinate file: plane coordinates and geodetic coordinates. However, it should be noted that the point number must correspond to the continuous equal sign“=====”The upper part is the coordinates of the current coordinate system, and the lower part is the coordinates of the target coordinate system.

Click the "Geodetic coordinate results Html file" hyperlink:

Click the hyperlink of "plane coordinate result Html file":

Click the "User Log File" hyperlink:

explain:

If the software finds problems during operation, it will be automatically recorded in the "User Log File" to help users find problems and find problems.

Click the "Geodetic coordinate result Word file" hyperlink:

Click the "Geodetic coordinate result text file" hyperlink:


Click the "Geodetic coordinate result Excel file" hyperlink:

Click to open the hyperlink of "plane coordinate result Word file":

Click the "Text file of plane coordinate results" hyperlink:

Click the "Excel file of plane coordinate results" hyperlink:

(2)Convert plane coordinates

That is, use the common point to transform the uploaded 1980 plane coordinates. Set the parameters unchanged and upload the 1980 plane coordinates. As shown in the figure:

Click the "Geodetic coordinate results Html file" hyperlink:

Click the hyperlink of "plane coordinate result Html file":

so(1)and(2)The plane coordinates and geodetic coordinates obtained are the same. This fully proves that the plane coordinates obtained by the transformation of geodetic coordinates are correct, and the geodetic coordinates obtained by the transformation of plane coordinates are also correct.

3.2 Convert coordinates with conversion parameters

The results of coordinate transformation using the above transformation parameters are identical, and the results of various tables will not be repeated here. The operation process is basically the same, just select "Upload conversion parameter file" to miss you, and the rest remains the same.

There are also two cases when coordinate conversion is carried out with conversion parameters:

(1)Convert geodetic coordinates

(2)Convert plane coordinates

The conversion results are the same. I won't repeat them here.

In addition, for the above conversion parameters, if you want to convert from the 1984 coordinate system to the 1980 coordinate system, you only need to reverse the above conversion parameters with a minus sign, and do not need to recalculate.

4 Stand-alone operation

The operation of the stand-alone version is slightly different from that of the network version, and the results are the same. Therefore, only a brief description is given. In order to avoid repetition, no examples are given.

Running this program will first present the boot interface:

Click "?" in the upper right corner to display the "Program Instructions" interface of the program:

Degrees of angle.Minute and second "format, such as 27 ° 03 ′ 54.203″27.0354203。

Click "Enter" to open the main interface:


This is the main interface of this program.

Click "?" in the upper right corner to display the "Program Instructions" interface of this form:

Coordinate conversion steps:

Enter coordinates in the left window or open the coordinate text file to load coordinates.

In the lower left corner of the form, select whether you want to convert to the coordinate of 3 degree band or 6 degree band.

Click "Parameter setting" to open the parameter setting interface for relevant settings(See details below)。

Then click the "OK" button, and then the "View Result Set" command becomes available. Click it to display the result sets in various angle unit formats and four file formats. Users can choose to use these results as needed.

The operation of the parameter setting form is described below.

Click the "Parameter setting" button to open the "Geodetic coordinate conversion setting" window:


Click "?" in the upper right corner to display the "Program Instructions" interface of this form:

Select the current coordinate system and target coordinate system, manually enter the common point coordinates or import the common point coordinate text file.

The user selects the number of parameters according to the work needs. Then click "Parameter calculation", and the program will fill the calculated parameters into the text box under "I have conversion parameters". If the user has conversion parameters, it is only necessary to fill the conversion parameters directly into the text box. Each parameter occupies one line, and parameter calculation is not required. Finally, click "Finish" to return to the main window.

Pay attention to the red prompt at the bottom of the form to avoid selecting the wrong coordinate system.

The following is an example result of the stand-alone version. Its content is the same as that of the network version, so the files will not be displayed again.



大地坐标转换软件简介


运行本软件系统的软、硬件环境:

本软件系统分网络版和单机版。

1、网络版

又分为互联网版和局域网版。互联网版适合任何人在任何地点网上使用,局域网版适合于公司、单位使用。

用户方不需要安装该网络版软件,只需要上网浏览使用即可。

本软件系统的互联网版适合多种主流浏览器,最好使用等同于IE10.0以上版本。电脑、手机、虚拟机及全站仪等均可网上操作使用,不需要安装、不存在卸载。

2、单机版

单机版适合单台电脑和虚拟机使用。

1 概述

使用本软件的用户必须是测绘专业人员、或者是与测绘技术相关的人员,或具有相应技术资格的其他人员。

本软件系统为国家工程建设和科学研究领域中广泛采用的四种大地坐标系之间的相互转换。这四种坐标以所诞生的年代表示为:1954、1980、1984、2000四种椭球参考系。

本软件系统可以对平面坐标和大地坐标进行转换,不论是对平面坐标实施转换还是对大地坐标实施转换,结果均会给出平面坐标和大地坐标两种成果。例如,如果用户提交的坐标文件是大地坐标,则会给出转换后的大地坐标和3度带或6度带的平面坐标。如果用户给出的坐标文件是平面坐标,同样会给出转换后的大地坐标和平面坐标。

本软件系统采用统一的数据文件格式,使得用户便于掌握。

本软件系统采用智能化思想开发,使得用户操作过程简单化,轻松完成工作任务。因此,在操作的过程中由用户考虑的问题不多,用户只需要看下主界面上的几个简单控件元素,基本上就可以操作了。即,用户进行简单选择设置后只需要提交数据文件即可得到想要的转换结果。

说明:单机版保留了让用户选择解算转换参数个数的功能。

一般情况下:

一对公共点可解算3参数,

二对公共点可解算5参数,

三对公共点可解算7参数,

三对以上公共点可解算9参数。

但,单机版在“选择参数个数”组合框中给出了最大参数以下的参数个数共用户选择使用。例如,三对公共点可解算7参数,但同时也给出5参数个数和3参数个数,用户除了可以选择7参数外,也可以选择5参数或3参数,这时,参数个数越少其解算的精度越高。

而,网络版则是按一般情况自动确定的。

本手册所例举的案例以网络版为主,为避免重复内容出现,单机版只介绍使用说明和必要的理论交代。

2 数据文件格式约定

2.1 平面坐标数据文件格式

(1)对于平面坐标的数据文件格式的基本形式为:

点名NxEyH


点名NxEy

其中,

Nx表示正北方向为纵坐标轴正向,Ey表示正东方向为横坐标轴正向,此即测量坐标系。

其中的高程H不起作用,只是为了用户使用方便可以不必去掉。

2.2 大地坐标数据文件格式

(2)对于大地坐标的数据文件格式的基本形式为:

点名BLH


点名BL

其中,

B为纬度,L为经度,H为大地高。

其中的大地高H不参加计算,但在数据文件中可以保留。

2.3 公共点文件数据文件格式

用户提交的公共点坐标数据文本文件的格式是:

当前坐标系坐标

=============

目标坐标系坐标

注:应使用一个以上等号(建议采用五个以上二十个以下连续“=”为宜)作为两种坐标系坐标的分隔符。

公共点的点名应该相同,多于一个公共点时,其点名前后顺序应保持一致。

例子:

P01 Nx1 Ey1 H1

P02 Nx2 Ey2 H2

===========

P01 Nx1' Ey1' H1'

P02 Nx2' Ey2' H2'

2.4 转换参数数据文件格式

转换参数的排列顺序为:

三参数为:⊿X、⊿Y、⊿Z

五参数为:⊿X、⊿Y、⊿Z、da、df

七参数为:⊿X、⊿Y、⊿Z、ωx、ωy、ωz、m

九参数为:⊿X、⊿Y、⊿Z、ωx、ωy、ωz、m、da、df

在数据文件中,按照该顺序每个参数占一行。例如,一个五参数的数据文件格式应为:

⊿X

⊿Y

⊿Z

da

df

对应的具体参数值的一个实际例子如下:

-113.9035

-4.7058

6.8397

3.0000

0.00000000251

3.2 利用公共点转换坐标


上传文件前,用户需要点击“浏览”按钮浏览到要上传的文件选中它并打开,此时要上传的文件全路径就会显示在浏览按钮左侧的文本框中。如下图所示:

(1)对大地坐标进行转换

即,利用公共点对上传的1980大地坐标转换为1984坐标系坐标。

具体操作:选择当前坐标系为1980、目标坐标为1984,选中“上传公共点坐标文件”选项钮并浏览到公共点文件,即浏览到要上传的1980坐标系文件,然后,点击提交按钮便可以得到1984坐标系坐标,其中包括其平面坐标和大地坐标,以及四种文件格式的坐标文件。操作过程如下所示:

得到成果显示页面:


从以上成果显示页面中可以看到,公共点坐标文件中允许同时出现两种坐标:平面坐标和大地坐标。但需注意,点号必须对应,连续等号“=====”上半部分是当前坐标系坐标,下半部分是目标坐标系坐标。

点开“平面坐标成果Html文件”超链接:

可见,(1)和(2)所得到的平面坐标和大地坐标是相同的。这充分证明了,用大地坐标转换得到的平面坐标是正确的,用平面坐标转换得到的大地坐标也是正确的。

3.2 利用转换参数转换坐标

利用上述转换参数进行坐标转换的结果是完全相同的,这里不再重复贴出各种表格成果。操作过程基本相同,只需选中“上传转换参数文件”即可,其它不变。

利用转换参数进行坐标转换,同样存在以下两种情况:

(1)对大地坐标进行转换

(2)对平面坐标进行转换

转换结果相同,这里不再赘述。

另外注意,对于上述转换参数,若要从1984坐标系转换为1980坐标系,则只需要把上述各个转换参数反一负号即可,不必重新计算。

4 单机版操作

单机版与网络版版的操作稍有不同,所得到的成果都是一样的,因此,仅做简要说明,为避免重复,不再举例。

运行本程序将首先呈现引导界面:

点击右上角的“?”显示本程序的“程序使用说明”界面:

角度的“度.分秒”格式,如27°03′54.203″则表示为27.0354203。

点击“进入”打开主界面:


这就是本程序的主界面。

点击右上角的“?”显示本窗体的“程序使用说明”界面:

坐标转换操作步骤:

然后点击“确定”按钮,这时“查看成果集”命令变得可用,点击之将显示得到的各种角度单位格式和四种文件格式的成果集合,用户可根据需要选择使用这些成果即可。

关于参数设置窗体的操作介绍如下。

点击“参数设置”按钮将打开“大地坐标转换设置”窗体:


点击右上角的“?”显示本窗体的“程序使用说明”界面:

选择好当前坐标系和目标坐标系,手工输入公共点坐标或导入公共点坐标文本文件。

用户根据工作需要选择好参数个数。然后点击“参数计算”,程序会把计算好的参数填入“我有转换参数”下方的文本框中。如果用户有转换参数,则只需要把转换参数直接填入到该文本框中即可,每个参数占一行,不需要进行参数计算,最后点击“完成”返回到主窗体中。

注意窗体下端的红色提示,以免选错坐标系。

以下是单机版的一个例子结果,其内容与网络版相同,故不再重复展示其中的文件。
