ENG 130IN - Elementary Surveying

3 Credits, 5 Contact Hours
2 lecture periods 3 lab periods

Introduction to the subject of surveying as it pertains to the field of civil engineering. Includes measurement of distances, leveling, profiling and grade calculations, measurement of angles, remote elevations, and traverse closure. Also includes topographic surveys, public land surveying, and land ownership.

Prerequisite(s): MAT 189  

Course Learning Outcomes
  1. Perform measurements using steel tapes and electronic distance meters and calculate adjustments based on environmental factors.
  2. Determine vertical differences in elevation between points using closed level loops.
  3. Measure and calculate grade lines using field measured information and profile leveling.
  4. Perform the measurement of horizontal and vertical angles.
  5. Determine the heights and elevations of remote objects.
  6. Perform a traverse and calculate the closure based on the compass rule.
  7. Perform a topographic survey and prepare resultant map.
  8. Describe an overview of the survey of public lands.
  9. Define the principles of land ownership, deeds and easements, and boundary surveys.
