Besavilla Cartography Practice Exam

The depth in the ground for barangay boundary monuments is how many centimeters?

50 cm 60 cm 70 cm 65 cm

Correct Answer:

60 cm

Explanation:

In land surveying, the depth at which barangay boundary monuments are buried is chosen to keep the marker secure over time. Embedding the monument about 60 centimeters below ground level provides a stable anchor against soil movement, weather, and unintended disturbance, while still allowing enough of the marker to be located and identified in the future. A shallower depth, such as 50 cm, is more vulnerable to disturbance and displacement. Going deeper than standard, like 70 cm or 65 cm, makes the work harder without adding meaningful stability under typical conditions, so the established practice is 60 centimeters.
