Question 1

An offset is the measurement of an object's distance from the survey line.

Accepted Answer

Lateral

Answer

In surveying, an offset is a measurement taken to determine an object's distance from a main survey line. Specifically, it refers to the perpendicular or 'lateral' distance from the survey line to the point or feature being mapped. This method helps in detailing features that are not directly on the main survey line.

Question 2

Which of the following is not a tool used to establish correct angles?

Accepted Answer

Optical staff

Answer

Prism squares, cross staffs, and site squares are all surveying instruments specifically designed for setting out or checking right angles in the field. An optical staff, also known as a leveling staff or stadia rod, is a graduated rod used in leveling to measure vertical distances or elevations, not for establishing or measuring angles.

Question 3

In how many different chain kinds is chain surveying used?

Accepted Answer

5

Answer

Chain surveying, a traditional method of measuring distances, utilizes different types of chains depending on the required precision and units. There are typically five main kinds of chains employed: Gunter's chain, Engineer's chain, Metric chain, Revenue chain, and the Steel band or tape, each with specific lengths and link counts.

Question 4

The number of links in Gunter's chain is .

Accepted Answer

100

Answer

Gunter's chain is a historical surveying instrument, famously 66 feet long. This specific length was chosen because 10 chains equal one furlong, and 80 chains equal one mile. The chain is divided into 100 links, making each link 0.66 feet long, which simplifies calculations for area in acres.

Question 5

A line's direction in relation to a specific meridian is referred to as:

Accepted Answer

Bearing

Answer

In surveying, the 'bearing' of a line defines its direction relative to a specific meridian, which is a fixed reference line, usually North or South. It is expressed as an angle measured clockwise or quadrantal from this meridian. This measurement is crucial for accurately plotting and orienting survey lines.
