As your experience increases, you will realize that accuracy in surveying is very important because the
results of the surveys are the basis of other factors affecting sound decisions in engineering practice.
PART A - SURVEYING CAREER FIELD
1-1. Career Progression. The normal line of progression for a technical engineering specialist
(military occupational specialty (MOS) 51T) and a topographic surveyor (MOS 82D) are discussed in
Army Regulation (AR) 611-201.
a. The following listed subcourses for surveyor training are available from the United States
(US) Army Engineer School, Fort Leonard Wood, Missouri:
EN 0591 Surveying I (Mathematics and Surveying Principles).
EN 0592 Surveying II (Plane-Surveying Operations).
EN 0593 Surveying III (Topographic and Geodetic Surveying).
EN 0594 Surveying IV (Construction Surveying).
b. Subcourses EN 0591, EN 0592, and EN 0594 are intended to provide the theoretic training
required for a construction surveyor (MOS 51T20). Subcourses EN 0591, EN 0592, and EN 0593 are
intended to provide the theoretic training required for a topographic surveyor (MOS 82D20/30).
c. Surveyor training is not complete without some practical work in the field. This should
occur after the student has had experience handling and using at least one of each of the more common
types of instruments and equipment described in this lesson. Students enrolled in these subcourses
should be assigned to an organization or unit that does construction or topographic surveying. If they
are not, they must acquire on-the-job training while studying these subcourses.
PART B - GENERAL
1-2. Purpose of a Survey
. The earliest application
was for establishing land boundaries.
Surveying has also branched out to many fields that parallel the advancement of civil engineering and
civilization. Surveyors may be called upon to appear in court to substantiate definite locations of
various objects, such as those involved in major traffic accidents, maritime disasters, or even murder
cases. Surveying methods may be the same, but their purposes are varied. Generally, surveys are
For subdividing or establishing boundaries of land properties. (NOTE: As the value of real
estate increases, the demand for good land surveyors also increases.)
