GEOM 2120 - Pre-Entry Survey Computations

Geomatics Part-time Studies Course

School of Construction and the Environment

To support you and your education, BCIT is adapting applied learning in formats appropriate to the unfolding global situation. Spring and Summer PTS classes are being delivered in an online format unless you are notified otherwise.

Course Details

This course is a condensed version of Surveying Computations 1 and 2 of the full-time day program of the Geomatics Diploma Program. It prepares students to enter directly into the Diploma program at Level 3 in the Fall upon successful completion. A review of geometry and trigonometry as it applies to plane surveying problems will be covered. The sine law, cosine law and Pythagoras’ Theorem will be employed in survey applications. Azimuths and bearings will be defined and reductions from field observations will be introduced. The polar and rectangular coordinate systems will be defined and the conversion from one system to the other will be covered. Traverse calculations will be covered including the reduction of field data. The Compass Rule will be used for the adjustment of different types of closed traverses. Coordinate cross multiplication will be covered for determining the area of a polygon. Missing (omitted) part problems will be introduced to reinforce trigonometry used with triangles. The course will introduce control survey calculations using intersection and resection methods. The geometry of simple circular curves and the computation of curve layout data together with the theory and practical application of calculations for symmetrical parabolic vertical curves will be presented. Area calculations using a variety of methods will be discussed to enable the subdivision of land parcels to meet specific design requirements. Road cross-sectional areas and volume calculations for typical earthwork applications will be presented.


2 years post-secondary education in any of the following: geography, geology, math, physics or engineering.
