Total latitude of a line is computed using
ltanθ
lsinθ
lcosθ
lcotθ
In a traverse, departure is considered positive when the line lies toward
North
South
East
West
The independent coordinate system refers to coordinates measured from
(a)
A traverse in which the start and end points have known positions but are not the same point is called
Closed traverse
Link traverse
Free traverse
Open traverse
If the sum of the south latitudes exceeds the north latitudes, and sum of east departures exceeds west departures, the closing line lies in
NE quadrant
SE quadrant
NW quadrant
SW quadrant
In Whole Circle Bearing system, bearings are measured
From South, clockwise
From East, anti-clockwise
From North, clockwise
From North, anti-clockwise
Latitude of a line is measured along the meridian.
True
False
Assertion: True meridian is obtained with the help of astronomical observations. Reason: True meridian changes with time due to magnetic variations.
Both assertion and reason are true, and reason is the correct explanation
Both assertion and reason are true, but reason is not the correct explanation
Assertion true, reason false
Assertion false, reason true
Fill in the blank: Departure of a line is given by the expression (a) .
Total latitude of station B = Total latitude of station A + (a)
Fill in the blank: In Quadrantal Bearing system, the maximum angle measured is (a) degrees.
Fill in the blank: The total departure is taken positive when the movement is towards (a) .
A survey line AB is 80 m long and has a reduced bearing of N 30° E. Calculate the latitude of AB.
(a)
A survey line AB is 80 m long and has a reduced bearing of N 30° E. Calculate the departure of AB.
(a)
The latitude and departure of a line are +30 m and +40 m respectively. Determine the length of the line.
