In the context of survey maps, what does SOP stand for?

• A. Standard Operating Procedure
• B. Special Operation Plan
• C. System Operating Process
• D. Safety Output Protocol

Answer: (A)

Standard Operating Procedure is a documented, step-by-step set of instructions that governs how tasks are performed to ensure consistency, safety, and quality. In survey maps, an SOP specifies exactly how measurements are taken, how equipment is set up and calibrated, how data are recorded, and how results are processed and checked. Following an SOP keeps methods uniform across crew members and sites, which improves accuracy, enables data to be reproduced, and helps meet mapping standards and regulatory requirements. The other terms aren’t the standard terminology used in surveying practice, so the familiar and widely adopted phrase Standard Operating Procedure is the correct one.
