Which survey technique is used when accuracy is important?

• A. Trace and Mark
• B. Grid
• C. Box
• D. Bounce and Bypass

Answer: (B)

Accuracy in surveying relies on a systematic, repeatable pattern of measurements. Using a grid lays out the area with regularly spaced lines and intersection points, creating a network of measurements that can be cross-checked against one another. This redundancy helps detect and correct errors, improves consistency across the entire survey, and makes results easier to reproduce or adjust if needed. Because of that, the grid method is the clear choice when precision is important. The other techniques are typically faster or simpler and can introduce more variability or bias, which reduces accuracy.
