make field computations. The recorder is considered to be an understudy of the instrument man.
a. Under favorable conditions for observing, readings are made so rapidly that the recorder must be
methodical in order to not hinder the observations. Mental arithmetic must be infallible, as there is not
time for setting down readings and figuring by means of longhand during the steps of recording,
computing, and transcribing.
b. All of the records and blank forms should be neat and clear. The form is a valuable part of the
permanent record of the survey and may have to be referred to by personnel other than the observing
party.
c. As the work progresses, the recorder, under the direction of the observer, performs the following
functions:
Completes records of all observations.
Prepares the title page and index for the field book.
Cross-references, when necessary.
Describes all stations.
Makes transcripts of the results.
Records triangle closures.
d. Before going into the field, the recorder should be familiar with all notes and forms used in the
work. Headings and column rulings in the notebook should be prepared in advance.
e. All observations should be clearly and distinctly recorded on the proper forms. The numbers
must be written so that there is no chance of misunderstanding them. Erasures must never be made in
the original records. If it is necessary to change a figure, it should be lightly crossed out, and the correct
figure should be placed above it or to one side. The original entry should still be legible. Ensure that
each reading is recorded on the appropriate line so that no changes to the record are required.
