Cien 3053 - Elementary Surveying: Pacing

1) The document describes an elementary surveying laboratory exercise on pacing conducted by Polytechnic University of the Philippines students to determine individual pace factors without instruments. 2) Over multiple trials of known and unknown distances, students paced lines and calculated their mean pace and pace factor, measuring distances with an average precision of 3.59 meters. 3) The exercise aimed to develop skills in measurement, teamwork, and communication through pacing lines with natural steps and counting paces without instruments.

Remarks :

 The ends of line AB and every stations (every 10 meters) in the


course was mark with keel on the pavements.
 An invar tape was used to measure the line AB.
 The actual length was acquired by taping the whole course
once.
 The length of a single step is termed a pace. It may be
measured from heel to heel or toe to toe. Also each two paces
or double step is called a stride.
 Pacing consists of counting the number of steps in a required
distance and is best done by walking with natural steps.
 Pacing is used only when approximate results are satisfactory
such as for estimating distances use for sketching and is
reconnaissance surveys. Pacing is also used as a means of
checking distances measured by more accurate methods.
 To keep on the line while pacing, the strokes that were used as
markers for every 10 meters were used as guide to avoid any
change in direction in the line.
