FUNDAMENTAL SURVEYING Distance Measurement & Traversing 2

Question 1

What correction must be applied when a steel tape is used at a temperature different from its standardization temperature?

Accepted Answer

Temperature correction

Answer

Steel expands and contracts with temperature, so a temperature correction is applied using the coefficient of thermal expansion (0.0000065/F for steel).

Question 2

What is the 'departure' of a survey line?

Accepted Answer

The east-west (x-axis) component of the line

Answer

Departure is the east-west projection of a survey line, calculated as distance times sin(bearing).

Question 3

In the Compass (Bowditch) Rule for traverse adjustment, corrections are distributed proportional to:

Accepted Answer

The length of each course relative to total traverse length

Answer

The Compass Rule distributes closure errors proportionally to each course's length as a fraction of the total traverse perimeter.

Question 4

A line has an azimuth of 225 degrees. What is its equivalent bearing?

Accepted Answer

S 45 W

Answer

225 degrees azimuth falls in the SW quadrant; bearing = 225 - 180 = 45, so the bearing is S 45 W.

Question 5

What is the 'latitude' of a survey course?

Accepted Answer

The north-south (y-axis) projection of the course

Answer

Latitude is the north-south component of a survey line, calculated as distance times cos(bearing).
