What is an "offset line" in surveying?

• A. A line that forms a right angle to a baseline
• B. A line parallel to a baseline used for measurements
• C. A diagonal line to measure elevation changes
• D. A boundary line marking property limits

Answer: (B)

An "offset line" in surveying is defined as a line that runs parallel to a baseline and is used to take measurements at a specified distance from that baseline. This technique is valuable because it allows surveyors to gather data without directly obstructing the main line of survey, facilitating more efficient data collection in various environments. By utilizing an offset line, surveyors can draw construction lines, control points, or other critical references while maintaining a safe distance from obstacles or site conditions that might complicate direct measurements. The use of offset lines is common in various applications, including route planning for highways and the placement of utilities, as they help maintain alignment and spatial relationships throughout the surveying operation.
