15.2.2. Control Point Establishment

Try these first

1. 1.

   What are permanent survey markers used for?

   Hint

   Think about what helps surveyors keep things straight and accurate.

2. 2.

   Why are benchmarks important in surveying?

   Hint

   Consider how heights might need to be measured in construction.

3. 3.

   What is the primary purpose of control points in surveying?

   • To provide reference for distances
   • To measure temperatures
   • To monitor weather conditions

   Hint

   Think about why surveyors need reliable reference points.

4. 4.

   Is GNSS used for geo-referencing control points?

   • True
   • False

   Hint

   Recall the technology used for accurate positioning.

5. 5.

   Consider a large infrastructure project that failed due to poor surveying. Analyze how improper control point establishment may have contributed to this failure.

   Hint

   Evaluate both the implications on safety and financial repercussions.

6. 6.

   Evaluate a situation wherein a GNSS device went offline during critical measurements. What steps would you take to mitigate the risk of inaccuracies?

   Hint

   Think about what redundancy measures you can use.
