Center of the instrument and the target and the elevation

Reference no: EM13536743

Stadia is used to estimate the distance from the instrument to a target. Using inclined sights the horizontal distance and vertical distance between the center of the instrument and the target and the elevation of the rod can be determined.

1) determine the horizontal distance, given:Stadia Top=8.5 ,Stadia Bottom 6.21, vertical angle= -8 degrees 42 minutes.

2)If the ground elevation at the instrument is 2045' msl (mean sea level), what is the ground elevation at the rod?
