Introduction to Angles and Mapping

Students at a 2023 LTAP surveying course

Please note: The spring 2024 session has been canceled. Information about future sessions will be posted as it becomes available.

About the Course

This hybrid course introduces students to angles and direction (including bearings and azimuth) and coordinate geometry calculations. 

The online portion of the course will describe the equipment, procedure, and note-taking required to conduct both a simple traverse with corrections and collect topographic survey data. Then, at an in-person field lab workshop, students will collect data and complete a simple exercise to manually transfer mapping notes to paper format.

Course Requirements

Students must complete the required online coursework prior to the field lab workshop. 

All students will need to use their own (agency-supplied) survey equipment and must bring the following to the in-person field lab workshop:

  • Total station
  • Charged batteries
  • Tripod
  • Tribrach
  • Prism
  • Survey rod

Course Objectives

After completing this course, students will be able to:

  • Set up a survey tripod
  • Operate a total station
  • Manually record and reduce traverse notes
  • Manually record and reduce mapping notes
  • Manually transfer mapping notes to paper format

Who Should Attend

This course is meant for public agency personnel or anyone interested in learning the basics of land surveying and differential leveling. It is designed for anyone who performs civil design data collection or uses the information in their job. The techniques covered are applicable for field data collection for roadway or civil design, or for verification in the field during construction.
