Problem 1

The forward and inverse distances of a line in an X,Y system:

a.       Are different

b.      Are the same

c.       Depends on the azimuth

Problem 2

Total station distances are based on:

a.       Speed of light

b.      Time of electromagnetic propagation

c.       Multiple wave lengths plus phase shift

Problem 3

Legally, surveyors must report distances that are:

a.       Horizontal

b.      Vertical

c.       On a slope, as measured

Problem 4

The vertical angle of an instrument is called:

a.       Zenith angle

b.      Vertical angle

c.       Depends on instrument setting

d.      Flipped angle

Problem 5

The azimuth of a line is measured from:

a.       Magnetic North

b.      Astronomic East

c.       Astronomic South

d.      Astronomic North

Solution

1) Option B is correct. In a line forward and backward distances are same.

2)Option B is correct. it depends on the electro magnetic propagation.

3)Option A is correct. The distances that are measured in surveying are horizontal distances. So, he has to submit horizontal distances.

4)Option B is correct. It is called vertical angle itself.

5)Option D is correct. It is measured from north in a clockwise direction.
