7.9.2 Foresight, backsight and intermediate sights The word sight denotes either
an observation on a staffer the resulting staff reading. The first sight taken after
setting up the instrument at a point is the backsight. It should be to a point whose

measuring procedures being followed: (1) a single foresight pointing on the sun
for each pointing on the backsight mark or (2) multiple foresight pointings on the
sun for each pointing on the backsight mark. For the single foresight procedure, ...

6.3.l Rise and Fall Method Each reading is entered on a different line in the
applicable column, except at change points where a foresight and a backsight
occupy the same line. This is to connect the line of sight of one set up of the
instrument ...
The term backsight has two uses in surveying. When shooting elevations, a
backsight (BS) is a rod reading taken on a point of known or assumed elevation.
The elevation of the point would be known if the station was a true benchmark.
Backsight at station 1 = 2.457 – 0.827 = 1.63 m The R.L of station 2 is missing.
R.L of station 1 is 150 m and there is a fall of 0.827 m from station 1 to station 2.
Therefore, R.L of station 2 must be less than that of station 1. R.L. of station 2 =
150 ...

Introduction to Mine Surveying
The actual angle right (124° 51.9') measured at A, backsight B, foresight sun,
under the above assumption becomes an angle left. Subtracting it from 360°
gives the angle right, 235° 08' 062, measured at A, backsight sun, foresight B.
Therefore ...

15.3.2. Backsight. A backsight (BS) is a rod reading taken on a point of known or
assumed elevation. It is the vertical distance between the line of sight through the
instrument and the point of known or assumed elevation on which the rod is set.
