Rise and Fall Method
The second change point was a benchmark of elevation 175975. This method is generally used where more number of readings can be taken with less number of change points for constructional work and profile levellings. Rise And Fall Method Numericals Of Rise And Fall Method 3 Surveying Vertical Angles Civil Engineering Works Height of instrument method deals with obtaining the RL of the line of collimation by adding BS reading of a point whose RL is known. . From this the staff readings of all intermediate stations is subtracted to get the. 1585 1315 2305 1225 1325 1065 1815 and 2325. Use the rise and fall method. HI method is less tedious more rapid and simple method. Eight readings were taken with a level in sequence as follows. As we know there is an arithmetic check to.
