Instrumentation VII: Applications of Angle Measurement [0:23]

In this second course on applications of angle measurement, we focus on types of problems and information required on the CST, FS, and perhaps even the PS exams as they relate to angle measuring devices such as the transit, theodolite, and total station. Nomenclature of angles measured and what they mean is first discussed, so that given, for example, an interior angle in a polygon, the exterior and deflection angles may be calculated as well as how the concept of measured “angles to the right.” To be able to calculate angular closure when a polygon is measured, the fundamental equations for calculating the theoretic values for these types of angles are covered. Running time 23 minutes.

• The basic components of a transit and how it was used
• How the theodolite is similar to and yet different from the transit
• About various types of functionalities provided by various types of total stations
• Reduction of field notes of angle measurement by the repeating and direction methods.
