This course offers basic forestry measurement procedures, with emphasis on field navigation and mapping skills. Topics include basic surveying and topographical mapping. Hands-on applications will include the use of levels, GPS, hypsometers (Vertex) and lasers (Impulse).
This course was retired after the Spring/Summer 2007 term and is no longer offered through BCIT Part-time Studies.
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.
