LESSON 6: TRAVERSE SURVEYING

Question 1

Type of survey in which several connected survey lines form the framework and the directions and lengths of the survey lines are measured with the help of an angle measuring instrument and tape or chain respectively.

Answer 1

TRAVERSING

Question 2

When the lines form a circuit which ends at the starting point, it is known as a ________

Answer 2

Closed Traverse

Question 3

When the lines form a circuit ends elsewhere except the starting point, it is an _______

Answer 3

Open Traverse

Question 4

The ______ is always measured parallel to the reference meridian (North-South line) and the _______ is always perpendicular to it

Answer 4

latitude, departure

Question 5

The_____ is usually a short line of unknown length and direction
connecting the initial and final stations of the traverse.

Answer 5

linear error of closure (LEC)

Question 6

The ________ is solved by taking the ratio of the linear error of closure (LEC) to the total length of the traverse

Answer 6

relative error or precision

Question 7

The procedure of computing the linear error of closure and applying corrections to the individual latitudes and departures to provide a mathematically closed figure.

Answer 7

Traverse Adjustment
