Measurement of Horizontal Distances

Question 1

consists of counting the number of steps or paces in a required distance.

Answer 1

Pacing

Question 2

the length of a step in walking.

Answer 2

Pace

Question 3

equivalent to two paces or a double step.

Answer 3

Stride

Question 4

the length of one’s pace.

Answer 4

Pace factor

Question 5

a mechanical counter hand carried to register the number of paces.

Answer 5

Pedometer

Question 6

a mechanical counter strapped to the leg of the pacer. This device will register a pace by
impact each time either foot touches the ground.

Answer 6

Passometer

Question 7

based on the optical geometry of the instruments employed and is an indirect method of measurement.

Answer 7

Tachymetry or Tacheometry

Question 8

a simple device that can be attached to a wheel for purposes of roughly measuring surface
distances. The wheel is rolled over the distance to be measured and the number of revolutions of the wheel is directly registered by the device.

Answer 8

Odometer

Question 9

basically consists of a small wheel which is attached to a rod and handle, and can
be pushed by an operator. It is suitable for measuring distances along irregular or curved lines and boundaries.

Answer 9

Measuring wheel

Question 10

usually hand-held or mounted on a small tripod, can be used to determine
distances approximately simply by focusing.

Answer 10

Optical rangefinder

Question 11

the person responsible for the accuracy and speed of all linear measurements
with the tape.

Answer 11

Head tape man

Question 12

keeps a record of all measurements, sketches, and observations taken during the process of measurement.

Answer 12

Recorder

Question 13

the person whose duty is to hold the range pole at selected points.

Answer 13

Flagman

Question 14

the person whose duty is to assist the head tape man during a taping operation. He is the one who holds the 30-m end or any intermediate meter mark of the tape during measurement.

Answer 14

Rear tape man

Question 15

Enumerate the procedure in taping.

Answer 15

• Aligning the tape
• Stretching the tape
• Plumbing
• Marking full tape lengths
• Tallying taped measurements
• Measuring fractional lengths

Question 16

holding the tape horizontally above ground and to plumb at one or both ends when
taping on sloping or uneven terrain surfaces.

Answer 16

Breaking tape

Question 17

The corrections for the effects of incorrect length of tape, temperature, tension, slope, and sag may be combined as a single net correction per tape length. Each correction is computed separately and it is important to identify which correction tends to make the tape too long or too short.

Answer 17

Combined correction
