Topics
Compass Surveying (Fore Bearing And Back Bearing, Magnetic Declination, Angle of Dip)
Bearing measured from one station to adjacent next station in the direction of traverse is called fore bearing. Back Bearing, Magnetic Declination, Angle of Dip are discussed in detailed.
Levelling (Correction in Levelling, Distance of Visible Horizon, Reciprocal Leveling, ETC)
In levelling, we are details discuss about elevation & altitude, reduced level, mean sea level, bench marks(B.M), horizontal line, vertical line, level line, back sight reading, fore sight reading, intermediate sight reading, method to find reduced level, height of instrument, rise and fall method, inverted staff, correction required in levelling work, distance of visible horizon, reciprocal leveling, collimation error, angular / inclination error, sensitivity of bubble tube, the sensitivity of level tube increases with?.
