Copy the above data and save it in a text file with a random file name, such as "abc1.txt”。Then run the "Gaussian projection and transformation" software. Because the above coordinate file is a 3 degree band of the 1980 coordinate system, you should select these two parameters on the interface, and then select "forward calculation"→Browse to "abc1.txt”open→Submit to get the following results:

Save the data in the above table to another data file, such as "abc2.txt”，The coordinate system and projection band remain unchanged, then run the "Gaussian projection and transformation" software and select "inverse calculation"→Browse to "abc2.txt”Open, and you can get "abc1.txt”The same result. You can also get a variety of results files in different angles and formats from the results page. The three parties are as follows:

复制上面的数据保存在一个文本文件中，文件名随便起，比如“abc3.txt”。然后运行“高斯投影与转换”软件，因为上述坐标文件是1980坐标系3度带，所以在界面上要选择这两个参数，然后选择“转换到6度带”→浏览到“abc3.txt”打开→提交，即可得到如下结果：

注：1980坐标系6度带坐标

注：可以把上面表格中的数据复制的一个文本文件中，坐标系不变，投影带选择6度带，选择“转换到3度”再变换到3度带的坐标。

把“abc3.txt”中的坐标转换到右邻(带号+1)带的坐标。坐标系和投影带不变，带号增量选+1，然后浏览到“abc3.txt”打开，提交，即可得到转换结果：
