3.3.10.11. Atmospheric errors

Try these first

1. 1.

   What causes atmospheric errors in Total Station measurements?

   Hint

   Think about the weather conditions affecting measurements.

2. 2.

   What is a nominal value?

   Hint

   What do we use when we don’t have precise environmental data?

3. 3.

   What primarily causes atmospheric errors in Total Station measurements?

   • Temperature
   • Humidity
   • Both A and B

   Hint

   Think about how weather can change signal pathways.

4. 4.

   True or False: Calibration of thermometers and barometers is essential for accurate surveying.

   • True
   • False

   Hint

   What happens if we don't maintain our measuring instruments?

5. 5.

   A survey is to be conducted over a distance of 5 km in varying weather conditions. Discuss how you would assess atmospheric conditions and what corrective measures you'd implement.

   Hint

   What specific tools would you use to gather necessary data?

6. 6.

   After surveying a site, you realize the environmental data for pressure was logged inaccurately. Discuss the potential impacts this could have on your results.

   Hint

   What aspects of construction or design might be affected by elevation errors?
