Example of leveling control network adjustment

Data file format description:
The leveling network data file is divided into three parts, with no less than 5 consecutive“=”Separate rows. Data is separated by commas or tabs or spaces or semicolons. The first character of the roll call must be a letter or a number.

Mean square error of prior unit weight(cm)
=========================
Known elevation points: point names altitude(m)
=========================
Height difference observation value: starting point name End name Altitude difference(m) distance(km)

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

水准测量控制网平差范例

数据文件格式说明：
水准网数据文件分三部分，用不少于5个连续“=”分隔行。数据之间用逗号或制表符或空格或分号分隔。点名的第一个字符必须是字母或数字。

先验单位权中误差(cm)
=========================
已知高程点：点名 高程(m)
=========================
高差观测值：起点名 终点名 高差(m) 距离(km)

复制下列数据保存在一个文本文件中，文件名随便起，比如“abc1.txt”。
