What does the survey form Course Leg do?

• A. Used when accuracy is important.
• B. Used in radiological surveys.
• C. Movement along a line oriented 45 degrees from the start line.
• D. Area monitoring.

Answer: (A)

This item tests the idea that a Course Leg survey form is used when accuracy matters. The form records each segment, or leg, of a survey course with precise measurements and directions so the entire path can be tracked, verified, and reproduced exactly. By documenting the course in defined legs, you can catch and correct deviations as you go, maintain tight positional control, and later recompute coordinates with confidence.

That focus on precise, segment-by-segment tracking is what sets it apart from broader uses. Radiological surveys and area monitoring involve collecting data over spaces or zones rather than sticking to a tightly defined, leg-by-leg path, and the specific notion of moving along a 45-degree line isn’t the defining feature of this form.
