5.1.5. Field Procedure of Total Station Survey

Try these first

1. 1.

   What is the purpose of leveling the Total Station?

   Hint

   Think about the effect of being unlevel in measuring.

2. 2.

   What instrument helps in centering the Total Station over the ground mark?

   Hint

   It's a device that helps with alignment.

3. 3.

   What is the first step in conducting a Total Station survey?

   • Setting up the Total Station
   • Inputting data
   • Sighting the prism

   Hint

   What comes before we can even start measuring?

4. 4.

   True or False: The optical plummet is used to level the Total Station.

   • True
   • False

   Hint

   What does leveling use instead?

5. 5.

   A surveyor sets up a Total Station at a height of 1.5 meters. During the survey, the measurements included angles of 45° to a target prism at a sloped distance of 100 meters. Calculate the horizontal distance to the prism.

   Hint

   Remember the cosine function relates the angle to the adjacent side in a right triangle.

6. 6.

   Explain how incorrect leveling of the Total Station could affect the accuracy of measured angles and distances during a survey.

   Hint

   Consider what happens to the angles measured if the instrument is tilted.
