Fore bearing ±90°
Fore bearing ±180°
Fore bearing ±270°
Fore bearing ±360°
Back bearing (BB) = Fore Bearing (FB) ±180° (+) ve signis used if FB is less @ than 180° এবং (-) ve sign is used if FB is more than 180°

Horizontal interval
Vertical interval
Contour interval
Contour distance
The constant vertical distance between two adjacent contour is called contour interval and horizontal distance between two contours is known contour gradient.
2044. During survey of an engineering project, the laws of accidental errors follow which of the following principle? [BB-20]
normal equation
probability law
laws of weight
most probable value
Laws of accidental errors follow the probability law, Which is having a definite law for accidental error accurence. It defines the errors and helps in expressing them in the form of equations.
2045. The value of representative fraction of a map is 1: 10000 then what is the measurement in map for actual distance 500m? [MOD-20]
5m
5cm
5mm
5in
10000 cm represents = 1cm 50000 (500x100)cm represents = 10000 cm = 5cm
2046. For a traverse containing 10 sides, what would be the correction applied for the first side, if it consists a closing error of + 1.92? [BB-20]
19.0
19.2
1.902
0.192
The correction for sides in a traverse is given as correction = e/N, where N is the number of sides and e is the closing error. On substitution, we get, correction = 1.92/10 = 0.192.

2048. Rise and fall method is used in-.
profile levelling
differential levelling
check levelling
none
It consists of determining the difference of elevation between consecutive points by comparing each point after the first that immediately preceding it. The difference between their staff reading indicates a rise fall according to the staff reading at the point.
