5 cards from this section. Quick, good the night before a test.
What does a tacheometer measure?
Think about how angles relate to distances.
Define stadia readings.
Look for terms related to staff measurements.
What is the equation for calculating horizontal distance in tacheometry?
Remember the role of the constants K and C.
True or False: The height of the instrument affects the RL calculation.
Think about how elevation is calculated.
A tacheometer at station A has a known height and three staff readings of 1.5, 2.2, and 3.0 meters. If K = 120 and RL of A = 150.0 m, calculate D and RL of the point observed.
Make sure to follow the steps carefully, calculating each variable one by one!
Given different values for K and various heights for the instrument, how would you adapt the calculation for a more complex project?
Focus on how changes in constants affect the end result and adjust your methods accordingly.
