LSIT Surveying Principles and Practices 5

Question 1

In the Public Land Survey System, how many acres are in a standard section?

Accepted Answer

640 acres

Answer

36 acres

Answer

160 acres

Answer

1,280 acres

Question 2

What is the purpose of 'double centering' (double-direct) when turning angles with a total station?

Accepted Answer

To eliminate or detect errors caused by non-perpendicularity of the horizontal and vertical axes

Answer

To double the measured angle for greater precision

Answer

To allow the instrument to be used in both direct and reversed positions simultaneously

Answer

To check that the prism target is centered on the point

Question 3

Which of the following best describes a 'deed of trust' in the context of land records research?

Accepted Answer

A security instrument using real property as collateral for a loan

Answer

A document transferring fee-simple ownership

Answer

A plat recorded to subdivide a parcel

Answer

A court order correcting a legal description

Question 4

A surveyor must establish a point on a hillside using three-wire leveling. What is the primary advantage of this technique over single-wire leveling?

Accepted Answer

It provides a check on each rod reading and improves precision by averaging three stadia readings

Answer

It eliminates the need for a turning point

Answer

It allows the instrument height to be measured directly

Answer

It removes the need for a Philadelphia rod

Question 5

What does 'excess of sections' in the PLSS refer to?

Accepted Answer

The assignment of fractional lots larger than quarter-sections along the north and west township boundaries

Answer

Sections with more than 640 acres caused by inaccurate original surveys

Answer

Sections created when a township contains more than 36 sections

Answer

Errors accumulated along the principal meridian

Question 6

What is 'total propagated error' (TPE) used for in precision surveying?

Accepted Answer

To estimate the combined effect of all identified error sources on the final measurement result

Answer

To determine the maximum reading error of a single instrument observation

Answer

To calculate the angular closure of a traverse

Answer

To determine how many decimal places to report in a final survey

Question 7

When a surveyor sets an azimuth from a sun observation, what correction accounts for the angular radius of the sun's disk?

Accepted Answer

Semi-diameter correction

Answer

Parallax correction

Answer

Refraction correction

Answer

Declination correction
