Arrange the following description in the form of profile level notes to complete the elevation. A level is set up and a reading of 2.579 m is taken on a benchmark and the elevation of which is 12.435 m. At the beginning of the line to be profiled the rod reading is 2.625 m, 30 m from the beginning it is 1.617 m, at 60 m it is 0.892 m, at 66 m and 81 m the rod readings are 1.281 m and 0.762 m, respectively. On a rock that is not on line, the rod reading is 0.555 m. The level is then removed ahead, set up and a rod reading of 1.952 m is observed, the rod still being held on the rock. The readings along the profile are then resumed 90 m from the beginning of the line, the rod reading is 1.159 m., 120 m. from the beginning of the beginning of the line rod reading is 1.434m, finally 150 m from the beginning of the next line the rod reading is 2.196. Compute the elevation at the point 60 m from the beginning of the line.

Question
Transcribed Image Text:Arrange the following description in the form of profile level notes to complete the elevation. A level is set
up and a reading of 2.579 m is taken on a benchmark and the elevation of which is 12.435 m. At the
beginning of the line to be profiled the rod reading is 2.625 m, 30 m from the beginning it is 1.617 m, at 60
m it is 0.892 m, at 66 m and 81 m the rod readings are 1.281 m and 0.762 m, respectively. On a rock that is
not on line, the rod reading is 0.555 m. The level is then removed ahead, set up and a rod reading of 1.952
m is observed, the rod still being held on the rock. The readings along the profile are then resumed 90 m
from the beginning of the line, the rod reading is 1.159 m., 120 m. from the beginning of the beginning of
the line rod reading is 1.434m, finally 150 m from the beginning of the next line the rod reading is 2.196.
Compute the elevation at the point 60 m from the beginning of the line.
