1.9. Survey Lines

Try these first

1. 1.

   What is a base line in surveying?

   Hint

   Think about the most important line in a survey setup.

2. 2.

   Why is it important for the base line to be on level ground?

   Hint

   Consider stability in measurement.

3. 3.

   What is the primary function of a baseline in surveying?

   • To provide a reference for calculations
   • To connect survey stations
   • To determine elevation

   Hint

   Think about what keeps everything aligned in surveying.

4. 4.

   True or False: The accuracy of the survey depends on the accuracy of the base line.

   • True
   • False

   Hint

   Consider what might fail if the base line is off.

5. 5.

   Given a rectangular survey area of 200m x 150m, outline how you would establish two base lines and justify their placements.

   Hint

   Focus on maximizing coverage and minimizing error.

6. 6.

   If a base line is inaccurately measured at 300m instead of the correct 280m, calculate the percentage error and discuss its implications.

   Hint

   Think about the cumulative impact of incorrect measurements.
