1. Accuracy and Measurement

Try these first

1. 1.

   What is the formula for calculating plotting accuracy?

   Hint

   Recall the thickness of the map's line.

2. 2.

   What are survey stations?

   Hint

   Think about where surveyors set up their equipment.

3. 3.

   What is considered maximum plotting accuracy at a 1:600 scale?

   • 10 cm
   • 15 cm
   • 25 cm

   Hint

   Refer to the scale and plotting accuracy calculation.

4. 4.

   True or False: Random errors can be identified and corrected systematically.

   • True
   • False

   Hint

   Think about how predictable or unpredictable these errors are.

5. 5.

   A surveyor needs to represent a structure that measures 20 cm on the ground with a 1:1000 scale. Can this feature be depicted accurately? Justify your answer.

   Hint

   Keep in mind the formula for plotting accuracy.

6. 6.

   Explain how improper survey station selection could impact the accuracy of a mapping project. Provide examples.

   Hint

   Consider how the positioning of these points affects overall measurements.
