What is the field book used for in surveying?

• A. A geodetic reference table
• B. A book used in surveying to record angles, stations, distances, observations
• C. A field notebook for weather observations
• D. A ledger of financial transactions

Answer: (B)

The field book is used to record the actual measurements and observations taken in the field. It serves as the permanent log of data that engineers and surveyors collect on site—documenting angles between lines, distances measured with tapes or EDM, station names or numbers, bearings, offsets, instrument readings, dates, and notes about procedures or conditions. This record is essential for reducing the data later to create maps, plans, and surveys, and it allows you to reconstruct and verify fieldwork if needed. Other options don’t fit because a geodetic reference table isn’t the practical notebook of measurements, weather logs belong in a separate record, and a ledger of financial transactions isn’t related to surveying data collection.
