1.1. Plotting Accuracy

Try these first

1. 1.

   What is the formula for calculating plotting accuracy?

   Hint

   Think about the thickness of the lines and scaling.

2. 2.

   Define what a survey station is.

   Hint

   Consider where you take measurements from.

3. 3.

   What is plotting accuracy based on?

   • Line thickness
   • Map scale
   • Both line thickness and map scale

   Hint

   Remember how plotting accuracy is calculated.

4. 4.

   True or False: A feature smaller than the plotting accuracy can be accurately represented on a map.

   • True
   • False

   Hint

   Think about the definition of plotting accuracy.

5. 5.

   Design a small map of a park and identify features that can be accurately represented without exceeding plotting accuracy at a scale of 1:2,000.

   Hint

   What will your feature sizes need to be?

6. 6.

   If a survey station is placed in a busy street and distances are measured in several angles, what could be the possible inaccuracies?

   Hint

   Think about factors affecting visibility and measurement.
