Lab 1 Pacing

The document provides instructions for a surveying lab on determining distance by pacing. Students will first measure a known distance and calculate their individual pace factor. Then using their pace factor, students will estimate the distance of an unknown course by counting their paces and making multiple trials. The lab aims to teach students how to use pacing to obtain approximate distances as a surveying technique.

FIELDWORK NO. 1: PACING

LEARNING OUTCOMES: After completion the fieldwork activity the students are expected to
determine individual pace factor and to utilize the pace factor to compute an unknown distance
by pacing.

MATERIALS:
1. Fiberglass tape
2. Range pole
3. Marking pins

INTRODUCTION:

Pacing furnishes a convenient means of obtaining approximate distances which is quite useful in
surveying. It is one of the methods of measuring distances and can be used to obtain a rough
check on more accurate measurements made with a tape. Pace Factor is the distance traversed
by an individual for every pace or step undertaken.

Figure 1. Pacing

PROCEDURES:

1. Determining Pace Factor

a. Select a straight and level course and on both ends establish markers at least 50 meters
apart. Designate these end points as A and B.
b. Walk over the course at a natural pace starting with either heel or toe over point A and
count the number of paces to reach point B.
c. For succeeding trials, walk from B to A, then A to B, until 10 trials are completed, and the
number of paces recorded accordingly.
d. Refer to the prescribed table for the recording of observed field data.

2. Determining an Unknown Distance

a. Your instructor establishes another straight level course for you to determine the
distance.
b. Walk over the course at a natural pace starting with either heel or toe over point A and
count the number of paces to reach point B.
c. For succeeding trials, walk from B to A, then A to B, until 5 trials are completed, and the
number of paces recorded accordingly.
d. Refer to the prescribed table for the recording of observed field data.
