1.19.1. Instruments used

Try these first

1. 1.

   What is a tacheometer?

   Hint

   Think about instruments used in distance measurements.

2. 2.

   What purpose does a levelling rod serve?

   Hint

   Consider its function alongside measuring instruments.

3. 3.

   What is a primary feature of a tacheometer?

   • It has a laser
   • It contains stadia hairs
   • It is purely digital

   Hint

   Remember the reference to specific parts of the instrument.

4. 4.

   True or False: A leveling rod's main function is to measure horizontal distances.

   • True
   • False

   Hint

   Think about the positions of the rod in relation to measurements.

5. 5.

   If the horizontal distance measured with a tacheometer is 200 meters using stadia hairs, calculate the angle of elevation if the staff reading is given as 2 meters.

   Hint

   Consider using tangent functions.

6. 6.

   A surveyor using a tacheometer measures the staff intercept as 0.5m. If the K value is 100, what is the horizontal distance?

   Hint

   Focus on the direct application of the formula.
