What are the five good booking methods used in chain survey?

In chain surveying, booking refers to the process of recording field measurements and observations in a systematic manner. It involves noting down the details of survey points, distances, and other relevant information. Here are five commonly used booking methods in chain surveying:

  • Single-Line Method: In this method, each line of the survey is recorded on a separate page of the field book. The page is divided into columns to record information such as the point number, distance measured, remarks, and sketches if necessary. This method provides a clear and organized record of each survey line, making it easy to refer to specific measurements.
  • Two-Faced Method: The two-faced method utilizes both sides of the page in the field book. One side is used for recording details of the forward survey, while the other side is used for the backward survey. This method allows for simultaneous recording of measurements in both directions, minimizing the chances of errors or omissions.
  • Tabular Method: In the tabular method, a table format is used to record survey data. The table consists of columns representing different parameters, such as point number, distance, bearing, remarks, and sketches. This method provides a structured and systematic approach for recording measurements, enabling easy comparison and analysis of survey data.

  • Skeleton Method: The skeleton method involves pre-drawing a skeleton plan or grid in the field book, representing the survey area with main lines, control points, and survey stations. The field measurements and observations are then recorded within this skeleton plan, noting the distances, angles, or other relevant information at each point. This method provides a visual representation of the survey data, making it easier to interpret and visualize the survey results.
  • L-section Method: The L-section method is commonly used for recording levels in chain surveying, especially for contouring or cross-sectional surveys. In this method, a vertical cross-section of the ground surface is drawn in the field book, representing the levels at different survey stations. The level readings and corresponding distances are recorded within this L-section, allowing for the accurate representation of the terrain and the profile of the surveyed area.

The choice of booking method may depend on factors such as the complexity of the survey, the preferences of the surveyor, and the specific requirements of the project. The selected method should ensure clear and organized recording of measurements, making it easier to analyze, process, and interpret the survey data.
