Distance Education Exam PROCTOR'S Instructions

 

 

Course Objectives:  Following this course, the student should be able to

  1. Compute coordinates of survey points by applying angles, distances, bearings, azimuths.
  2. Perform algebra and trigonometry operations on equations to "solve" for unknown quantities
  3. Compute survey coordinates by standard "COGO" operations called "traversing", "inversing", "bearing-bearing intersection", "bearing-distance intersection", "distance-distance intersection", and "resection".
  4. Calculate survey data by applying basic theory without software using a hand-held calculator similar to those approved for the board exams.
  5. Calculate survey data by applying basic theory in Microsoft "Excel" spreadsheet software.
  6. Calculate quantities of figures such as perimeters, areas, volumes. 
  7. Solve survey calculations such as "pre-determined areas", "missing traverse parts", "compound and reverse curves", and "radius calculations."
  8. Apply analytic geometry and matrix methods in survey calculations.
