Features include angle accuracy 1-5", reflectorless measurement, onboard computation, data storage, and programs for resection and setting out. Civil engineering applications include topographic surveys, setting out of structures, volume calculations, and deformation monitoring. ## Answer #### Total station A total station is an electronic theodolite combined with an electronic distance meter (EDM) and a microprocessor, so that horizontal angle, vertical angle and slope distance are measured together, and horizontal distance, elevation difference and coordinates are computed and stored. #### Typical features - Electronic angle measurement (accuracy 1″–5″) with digital display; automatic compensator for the vertical axis error. - Built-in EDM using an infrared or laser beam to a prism, or reflectorless measurement on surfaces; range of several kilometres with a prism. - Microprocessor that computes horizontal distance, vertical distance, coordinates (N, E, Z), and also remote elevation, missing line, area and offset. - Internal memory or memory card for data storage; data can be sent to a computer by cable or Bluetooth. - Laser plummet, dual-axis tilt sensor, keyboard and graphic display, and built-in programs for resection, setting out and traverse. - Corrections for temperature, pressure, curvature and refraction, and prism constant. - Motorised models: automatic target recognition, tracking and robotic control. #### Applications in civil engineering - Topographic and detail surveys; contour and DEM mapping. - Traversing and control surveys. - Setting out of buildings, roads, bridges, tunnels and curves. - Measurement of areas, volumes and cross-sections quickly. - Deformation and settlement monitoring of dams and structures. - As-built surveys and land (cadastral) surveys with direct transfer of data to CAD. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1.
