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.
- Understand some introductory principals of field sampling measurements.
