Copy the above coordinate data and save it in a text file with a random file name, such as "abc1.txt”。

Copy the above conversion parameters and save them in another text file with a random file name, such as "cs1.txt”。
Then run the "geodetic coordinate conversion" software. Because the data file is 80 coordinate system, it needs to be converted to 84 coordinate system, so select the original coordinate system 80 and the target coordinate system 84 on the interface, and select the upload conversion parameter file "cs1.txt”,Upload the coordinate file "abc1.txt”，Then click the "Submit" button to get the converted 84 geodetic coordinates and plane coordinates:

Convert the aforementioned coordinate system upside down and achieve the purpose of verification. At this time, select the original coordinate system 84 and the target coordinate system 80. This time, choose to upload the common point file, which has the same effect as selecting the conversion parameter file.

复制上面的坐标数据保存在一个文本文件中，文件名随便起，比如“abc1.txt”。
-113.9035
-4.7058
6.8397
复制上面的转换参数保存在另一个文本文件中，文件名随便起，比如“cs1.txt”。
然后运行《大地坐标转换》软件，因为数据文件是80坐标系，需要转换到84坐标系，因此界面上选取原坐标系80、目标坐标系84，并且选择上传转换参数文件“cs1.txt”、上传坐标文件“abc1.txt”，然后点击“提交”按钮，即可得到转换后的84大地坐标和平面坐标：

将前述坐标系倒过来进行转换，并达到验证之目的。这时，选取原坐标系84、目标坐标系80，这次选择上传公共点文件，此与选择转换参数文件的效果相同。
