Learning Outcomes

Upon successful completion, the student will be able to:

• Distinguish between several different types of surveys and know the purpose for each.
• Describe common sources of error in traverse surveys.
• Distinguish between precision and accuracy.
• Locate potential tie points on an aerial photograph and/or map and locate on the ground.
• Correctly use a field compass to measure bearings between features and to follow a bearing to a desired location.
• Determine the correct declination for a specific area and set the declination adjustment on a hand compass.
• Detect local attraction and record in field notes for later adjustments.
• Measure slope distance using pacing, chaining, tapes, estimation.
• Convert between slope distance and horizontal distance using slope tables and trig functions.
• Calculate change in elevation using % slope and measured distance.
• Record field traverse data including bearings, distance measurements, elevation and field mapping.
• Perform a simple closed traverse including slope distance and slope correction.
• Plot and draw an -adjusted' traverse.
• Quantify the amount of error in a traverse.
• Produce a map drawn to scale based on field observations and recorded field notes.
• Determine the height of objects on level or sloped ground using a chain/tape and clinometer.
