u COURSE (CATALOG) DESCRIPTION
SE 211: Surveying Basics
Definitions and concepts with a brief descriptions of historical development of surveying. Principles of survey observations and errors with a fully-worked example. Basic survey measurements. This overall topic includes: distance measurements, leveling with its principles and practical aspects, angle measurements. Use of electronic equipment in field observations. Applications, which cover a wide variety of topics relevant to the field of plane surveying.
MATH 107 (Algebra and Analytic Geometry).
u TEXT BOOK(S) AND/OR OTHER REQUIRED MATERIAL
· Elementary Surveying: An Introduction to Geomatics, 10/e @ 2002, Paul Richard Wolf, and Charles D. Ghilani, Prentice-Hall, Inc.
· Surveying with Construction Applications, Barry F. Kavanagh, Fifth edition, Prentice-Hall, Inc. (in reserve).
u COUSE OBJECTIVES
The goals for the course design are identified to give the students the principles of plane surveying and planimetric maps. Together with the other survey field work applications, it exposes the student to all traditional surveying measurements to a form useful in engineering projects and earth work problems. In particular, emphasis is placed to make a balance between theoretical topics and field applications.

u RELATIONSHIP OF COURSE TO POGRAM OUTCOMES
Upon completion of the course, students will:
a) Understand the principles of making reconnaissance, sketching, stationing, measuring by taping on level, and slope ground to produce a large scale map.
b) Apply knowledge of probability and theory of errors to know and analyze the precision and accuracy of the results.
c) Understand the theory and use of the fundamental ground surveying instrument – the tape, level, theodolite, EMDS, and palnimeter.
d) Be able to perform profile observations, calculations, and drawing.
e) Be able to measure horizontal angles by the direction method, and closing the horizon, and vertical angles.
f) Understand contours characteristics, and the principle of making interpolation to draw them.
