Angle Measurement—Transits and Theodolites

  • Edward G. Zimmerman


Three dimensions or combinations thereof must be measured to locate an object with reference to a known position: (1) horizontal length, (2) difference in height (elevation), and (3) angular direction. This chapter discusses the design and uses of surveyors’ transits and theodolites to measure horizontal and vertical angles.
