```									                              SU3150 - PRINCIPLES OF GEODESY

Credit Hours: 3 (0-3-0)

Course
Description: This course deals with concepts of astronomy and geodesy that are
relevant to the practice of surveying. They include theory, field techniques
and computations involved in the determination of true north, an
introduction to the figure of the earth and its geometric and physical
characteristics, datum and coordinate systems used in geodetic surveys.
Prerequisites: SU 3110, MA2150

Textbook: There is no text for this course. A set of notes developed by the instructor will be
available on the course web page under Course Notes. Additional references, including
the following publications, can be found in the university library.

Following outcomes are expected after completion of this course

1. Understanding basic concepts and applications of astronomy in surveying, and
ability to perform calculations related to determination of azimuth of lines
referenced to true north

2. Basic understanding of geodetic datums and related coordinate systems in geodesy
that are useful in the practice of surveying. Ability to perform geodetic
computations using such coordinate systems
3. Basic understanding of map projections and the U.S. State Plane coordinate
system, and ability to perform related computations
4. Basic understanding of the gravity field of the earth and its effects on survey
measurements

Fulfills items a, e, h, i and k of ABET criterion 3

Student Expectations:

The students are expected to have a sound background in algebra and
trigonometry and a thorough understanding of standard surveying techniques,
coordinate systems and computations. Knowledge of 2-D and 3-D geometrical
concepts and relevant mathematical treatments are essential for this course, and
the ability to visualize objects in 3-D space is an advantage

Also note that academic integrity must be maintained at all times. Any violation
of this policy with regards to assignments or exams will be brought to the notice
of Dean of Students.

Guidelines for Turning in Assignments

1. Every assignment is due on the due date indicated. Late assignments will only be
accepted from those who have made prior arrangements. This will only be for
exceptional circumstances.

2. All assignments should be submitted on 81/2 x 11 sheets of paper and should be
legible. Pages should be numbered and stapled together. No loose sheets or sheets torn
out of a spiral notebook will be accepted. Write your name, assignment number and
the course # clearly on the first page.

3. You are strongly encouraged to work the problems in groups, but each individual
should have a clear understanding of the problem and its solution. For this reason,
each individual must write up his or her solution. You are also encouraged to ask

4. Solutions to problems should be presented clearly and in a logical order in sufficient
detail to enable one to follow it easily . All work and formulas used must be clearly
shown and values obtained using computer programs must be shown with the
solution and not merely refer to computer printouts. The reasoning or logic used
in obtaining the solution must be clearly indicated.
5. Failure to follow above instructions will result in the loss of points
