This course is an introduction to the field surveying component of Geomatics. The lectures will cover the terminology (jargon) used, introduce basic theory and describe the procedures and expected outcomes for the field labs. These field labs will allow students to become familiar with the use of differential levels (both automatic and digital) and total stations. The course will include a basic introduction to errors as applied to differential levelling, angular measurements and distance measurements. Note keeping formats will be covered throughout the course. The field labs will be practical examples of typical industry situations. These include determining elevations by differential and trigonometric levelling, collecting data for a topographic plan, traversing to establish coordinates, using resection to determine coordinates and setting out points to meet boundary constraints. The course will include an introduction to electronic data collection and downloading. The astronomic portion of the course will include the following topics: the celestial sphere and its coordinate system; altitude and azimuth; declination, hour angle, right ascension; celestial latitude and longitude; time (sidereal, apparent, and universal); the equation of time; the determination of azimuth by time and altitude methods and the use of almanacs. The course is intended to cover the essential components of the entire first year of the Geomatics diploma program field courses. The field labs have been selected from first year field labs to try to provide direct entry students the skills to confidently enter the second year field courses.
2 years post-secondary education in any of the following: geography, geology, math, physics or engineering.
GEOM 2110, 2120 and 2130 are intended to be taken together. These courses are required for students with conditional acceptance into 2nd year of the Geomatics Diploma Program (Level 3) – contact Chris Thornton, Program Head, for more information.

Upon successful completion of this course, the student will be able to:
Define many basic terms used in the survey industry
Describe the proper care and handling of survey equipment.
Demonstrate suitable formats for note keeping.
Carry out various methods for determining elevations.
Assess the quality of, and adjust a differential level loop.
Measure horizontal and vertical angles using a theodolite and total station.
Measure distances with a steel tape and electronically and apply appropriate corrections.
Describe the basic parameters common to most total stations.
Assess and calibrate a total station for horizontal collimation and vertical index errors.
dentify sources of observational errors and explain how to manage them.
Carry out a traverse with a total station using onboard and external device software routines including “Free Station” and “Resection”.
Demonstrate the basic field procedures for setting out points.
Determine astronomic azimuth by time and altitude methods by solar and star observation.
Describe the equation of time, apparent time, sidereal time and Universal Time.
