1　summary

Angle conversion is quite widespread in surveying and mapping work, geological, geophysical and astronomical work. For example, the coordinate system adopted in GPS is generally the 1984 geodetic coordinate system, which is longitude and latitude coordinates and is in degrees. Some devices are“:”Representing degrees, minutes and seconds, such as 25 ° 38 ′ 26.5″，Often expressed as 25:38:26.5。In our daily work, we often use ° '″ to represent the angle, because it looks intuitive. In some data files, most of the angles expressed in real numbers are used, for example, the above angles are expressed in real numbers 25.38265。In angle calculation, the unit is radian or degree. There are also angles indicated by other separators, such as semicolons and commas, according to work convenience. Such as this, it is no problem to convert a few angles manually or with a calculator, but it is difficult and time-consuming to convert thousands or more angles. Therefore, this software system is developed to meet the needs of conversion between various angles.

This software system unifies and transforms several angle formats commonly used in surveying and mapping work to meet the needs of various work. In addition, you can add, subtract, and multiply angles with infinite terms. 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. The operation process is simple and clear. That is, open the data file→Execute a command→Get the conversion result. Among them, the command refers to selecting a function in the function selection drop-down box and immediately executing it to give the result.

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.

1,Introduction to main interface

After running this program, the main interface will be displayed:

Users can directly enter the original data in the left window, but it is generally appropriate to "import" the data text file.

Users can directly copy the result data into other documents to paste the data, or save it as a text file.

Click“<<<”You can use the converted results as input data to continue the conversion of other angle formats until you want the results.

“The function selection window contains the following selectable functions:

Enlarged representation of function selection:

The "?" in the upper right corner is the program instructions. Click "?" to pop up:

“The decimal places reserved in "Result Data" are preset to 1 to 20 decimal places. You can also customize more decimal places reserved.

2,Operation steps

Run the software;

Enter data or "import" data text file in the "original data" window on the left;

Select a function in the "Select Function" window and get the result in the "Result Data" window on the right. You can copy the data or save it as a text file.

Select or customize the number of decimal places to keep in the "Decimal Places" window at the lower right corner. Users can change the number of decimal places at any time. For example, after the user chooses to retain 2 decimal places, it is found that 3 decimal places should be retained. At this time, the user can also choose to retain 3 decimal places again, because the complete decimal part is hidden. However, when the user saves the file, the decimal part is only saved to 3 digits, and the hidden decimal part behind it will not be saved.

The "infinite operation" in the last two functions means that there is no limit to the number of items participating in the operation. For example, it can be the addition and subtraction of any angle and the multiplication of angle multiples.

3　Example of angle conversion

Import geodetic coordinates:

（1）“degree.Convert the "minute second" format to a group of other four formats

Select decimal place 2 in the lower right corner of the form:

Visible, second to 2 decimal places:

（2）“°′″”Format to other four formats

（3）“degree:branch:Second "format to other four formats

（4）“Convert the "degree" format to a group of other four formats

（4）“"Radian" format to other four formats

3　Example of angle operation

（1）“Infinite operation of angle addition and subtraction "example

23°33′21.5″+23°33′21.5″ The result is: 47 ° 06 ′ 43.00000035994″

23°33′21.5″-23°33′21.5″ The result is: 0°00′00.00000036000″

（2）“An example of "angle addition and subtraction multiplication infinite operation"

23.33215+23.33215-[2]*23.33215 The result is: 0°00′00.00000036000″

Examples of more complex mixed operations in arbitrary data formats:

23°33′21.5″+23.33215-23:33:21.5+[2]* 23.33215-23°33′21.5″-[2]* 23.33215

-23.33215+23:33:21.5

The result is: 0 ° 00 ′ 00.00000036021″，The computer error not considered is 0 ° 00 ′ 00 ″.

It can be seen that the above computer errors should be ignored and the calculation results are correct.

1　概述

角度转换在测绘工作及地质、物探、天文工作中是相当广泛存在的。例如，GPS中采取的坐标系一般都是1984大地坐标系，是经纬度坐标，并且是以度为单位的。一些设备是以“:”表示度分秒的，例如25°38′26.5″，常表示成25:38:26.5。我们在日常工作中往往是以°′″表示角度的，因为看起来视角直观。在一些数据文件中，大都习惯用实数表示的角度，如上述角度表示为实数25.38265。而在角度计算中又都是以弧度或度为单位的。还有根据工作方便采用其他分隔符，如分号、逗号等表示的角度。诸如此类等等，对于少数几个角度手工或用计算器转换是没有问题的，但对于成千上万甚至更多的角度转换就困难了，耗时耗力。因此，开发了本软件系统以满足各种角度之间的转换工作需要。

本软件系统对测绘工作中常用的几种角度格式进行统一相互转换，以适应各种工作需要。并且，可以对角度的加、减、数乘进行无限项运算。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。操作过程简单明了。即：打开数据文件→执行一条命令→得到转换结果。其中，命令指的是在功能选择下拉框中选择一种功能并立即执行给出结果。

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。

2　单机版操作

1、主界面介绍

运行本程序后显示主界面：

用户可以直接在左窗口中输入原始数据，但一般以“导入”数据文本文件较为合适。

用户可以直接复制结果数据到其它文档中去粘贴数据，也可以保存为文本文件。

点击“＜＜＜”可以把已经转换的结果当做输入数据继续进行其它角度格式的转换，直到您希望的结果。

“功能选择”窗口中包含可选择的功能如下：

功能选择放大表示：

右上角的“？”是程序使用说明。点击“？”弹出：

“结果数据”保留的小数取位预设为1至20位小数，用户还可以自定义更多的保留小数位数。

2、操作步骤

运行本软件；

在左侧“原始数据”窗口中输入数据或“导入”数据文本文件；

在“选择功能”窗口中选择一个功能，即时在右侧“结果数据”窗口中得到结果，用户可以复制其数据，也可以保存为文本文件。

在右下角“小数位数”窗口中选择或自定义需要保留的小数位数。用户可以随时改变保留不同的小数位数。例如，用户选择保留2位小数后，发现应该保留3位，这时用户还可以再次改为选择保留3位小数，因为完整的小数部分是隐藏的。但，当用户保存文件时，小数部分只保存3位，其后面隐藏的小数部分不会被保存下来。

最后两个功能中的“无限运算”的意思是参加运算的项目数没有限制。例如，可以是任意个角度的相加减和角度倍数数乘。

3　角度转换的例子

导入大地坐标：

（1）“度.分秒”格式转其它四种格式一组

在窗体右下角选择小数取位2：

可见，秒保留2位小数：

（2）“°′″”格式转其它四种格式一组

（3）“度:分:秒”格式转其它四种格式一组

（4）“度”格式转其它四种格式一组

（4）“弧度”格式转其它四种格式一组

3　角度运算的例子

（1）“角度加减无限运算”例子

23°33′21.5″+23°33′21.5″ 结果为：47°06′43.00000035994″

23°33′21.5″-23°33′21.5″ 结果为： 0°00′00.00000036000″

（2）“角度加减数乘无限运算”例子

23.33215+23.33215-[2]*23.33215 结果为： 0°00′00.00000036000″

更复杂的任意数据格式混合运算的例子：

23°33′21.5″+23.33215-23:33:21.5+[2]* 23.33215-23°33′21.5″-[2]* 23.33215

-23.33215+23:33:21.5

结果是：0°00′00.00000036021″，不考虑计算机误差为：0°00′00″。

可见，以上计算机误差应忽略不计，计算结果都是正确的。
