Field activities and Instruments

• Chief of Party: Person responsible for the overall direction, supervision and operational control of the survey party
• Instrument Man: Duty is to set up, level and operate surveying instruments such as the transit, level, theodolite, etc.
• Data processor: Duty is to perform computations of survey data and works out necessary computational checks required in a field work operation
• Technician: Responsible for the use and operation of all electronics instruments required in a field work operation
• Recorder: Duty is to keep a record of all sketches, drawings, measurement and observations taken or needed for a field work operation
• Flagman: Duty is to hold the flagpole or range pole at selected points as directed by the instrument man
• Head and Rear tape man: Responsible for the accuracy and speed of all linear measurements with tape
• Rodman: Duty is to hold the stadia or leveling rod when sighted
• Pacer: Duty is to check all linear measurement made by the tapeman
• Axeman/lineman: Duty is to clear the line sight of trees and obstructions
• Aidman: Duty is to render first aid treatment to members of the party
• Utility man: Duties are to render other forms of assistance needed by the survey party or as directed by the chief of party
• Note keeping must follow a consistent simple style of writing
• Note keeping must record directly in the fieldbook immediately following a measurement
• Do not erase recorded data; for erroneous entry, a line is run through it and correct value is written above the mistake
• Indicate nort at the top of the page of the field notebook for all sketches shown in plan and draw a meridian arrow
• Transit: Universal Surveying Instrument; Primarily used for measurement of layout of horizontal and vertical angles
• Theodolite: A precision instrument used for measuring angles both horizontally and vertically; angular measurements are more accurate than transits
• Total station: An electric transit and an Electronic Distance Measurement (EDM) device combined into one instrument
• Level: Used to measure elevations of points and differences in elecation between points based on a reference benchmark
