LINEAR MEASUREMENTS		3	15
Introduction to surveying	Define surveying. Discuss the common tools of surveying. Discuss the importance of surveying.
Types of surveys	Describe each of the following types of surveys: plane surveying, geodetic surveying, photogrammetric surveying, control surveys, construction surveys, property surveys, topographic surveys, route surveys, and hydrographic surveys.
The surveying profession	List three government agencies that do surveying and mapping in the United States on a large scale. Describe common job titles in the surveying profession. Discuss the steps in becoming a professionally licensed surveyor.
Theory of measurement	Describe each of the following types of measurements made by surveyors: horizontal angles, horizontal distances, vertical angles, vertical distances, and slope distances.
	Describe the common units of measurement (both English and metric) used for length, angle, area, and volume. Convert measurements in length, angle, area, and volume between English and metric units. Record data giving proper consideration to significant figures. Describe the proper system for rounding off numbers. Differentiate between direct and indirect measurements.
Measurement errors	Describe examples of natural, instrumental, and personal errors in surveying. Define systematic or cumulative errors. Define random or accidental errors. Explain why random errors tend to be compensating. Define: discrepancy, precision, agreement, and accuracy. Describe steps that can be taken to minimize surveying errors.
Survey field notes	Discuss the legal significance of survey field notes.
	Describe each of the five requirements for good field notes: accuracy, integrity, legibility, arrangement, and clarity. List common types of field books. Copy sample data into field books using proper notetaking techniques.
Methods of linear measurement	Describe the general procedure for measuring horizontal distances by: pacing, odometer, stadia, taping, and EDM. Measure horizontal distances by pacing to within an accuracy of 1:50. Maintain proper fieldnotes.
Taping	Describe the care and use of the common tools required for taping over level and sloped ground. Demonstrate the six steps of taping: lining in, applying tension, plumbing, marking tape lengths, reading the tape, recording the distance.
	Demonstrate the use of a fiberglass tape.
	Demonstrate the use of a steel surveyors chain.
	Describe the common sources of error in taping and list what can be done to minimize each error including: incorrect tape length, temperature, pull, sag, poor alignment, tape not horizontal, improper plumbing, faulty marking, and incorrect reading.
	Measure a distance on level ground to an accuracy of 1:3000. Measure a distance on sloped ground by breaking tape to an accuracy of 1:2000. Lay out a distance on level ground. Check the distance by repeat measurement. Distance should check by +/-0.05'. Lay out a distance on sloped ground. Check the distance by repeat measurement. Distance should check by +/-0.1'.
EDM	Observe distance measured with an EDM. Take proper field notes.
INSTRUMENT USE		3	15
Nomenclature	Describe the function and use of each part of a level. Describe the function and use of each part of a transit and/or theodolite.
Basic usage	Demonstrate proper care, storage, and field transportation of a level, transit, theodolite, and EDM instrument. Set up a level on any type terrain in five minutes or less. Set up a transit or theodolite over a point on level ground in ten minutes or less. Set up a transit or theodolite over a point on sloped ground in fifteen minutes or less.
ANGLES, BEARINGS, AND DIRECTIONS		4	10
Theory	Differentiate between horizontal and vertical angles.
	Describe compass theory. Define magnetic declination. Convert magnetic bearing to true bearing given declination.
	Describe each part of a surveyors compass.
