A tower appears in two successive photo-graphs taken at an altitude of 4000 m above datum. The focal length of the camera is 160 mm. The length of the air base is 300 m. The parallax for the top and bottom of the pole are 72 mm and 63 mm respectively. The height of the top of the tower above its bottom is nearly 70.50

The elevation of point A is at 1200' above sea level. What is the elevation of point B if the flying height is 12000' above ground, the parallax movement of point A is 3.1" and the parallax movement of point B is 2.8" on the stereoscopic images. The distance between primary points on photo 1 is 4.1" and is 4.2" on photo 2.
B and C were observed from point A where the instrument was set up at a height of 1.25m. Point B and C were ahead of point A. Below shows the data recorded as observed for points B and C. a. find stadia constant b. find the slope distance between the telescope at point A and rod reasiny at point B. c. find the difference in elevation between between B and C.
A vertical angle of -14°30' is read to a target 1.75 m. above point M. The measured inclined distance (S) is 644.15 m. and the elevation of point K is 320.70 m. above mean sea level. If the height of instrument at K is 1.27 m., determine the elevation of M, considering the effects of the earth's curvature and atmospheric refraction.
The upper and lower stadia hair readings on a stadia rod held at station B were observed as 3.50 and 1.00 m, respectively, with the use of a transit with an internal focusing telescope and having a stadia interval factor of 99.5. The height of the instrument above station A is 1.45 m, and the rod reading is taken at 2.25 m. Determine the horizontal distance between points A and B, and the elevation of point B, if the elevation of point A is 155.54 m, above mean sea level.
A backsight reading of 2.73 m is taken on point A and subsequently a foresight reading of 1.35 m is taken on point B from the instrument station. If the elevation of A is 386.70 m above MSL, the elevation of B should be:
If a total station is set up at station K6 then station X was observed, calculate the Zenith angle and the earths curvature and atmospheric refraction. Height of instrument is 1.55m and height of prism is 1.297 m
Determine the backsight or foresight distance for an instrument set up which will cause an error due to earth’s curvature and atmosphere’s refraction equal to 0.0015 m, 0.0575 m, 0.0986 m, 0.2935 m, and 0.8750 m.
In order to determine the stadia interval factor of a transit on the field, the transit was set up at a certain point on the ground. Observations were made on the rod placed at a distance of 100 m from the instrument and the rod readings were 3.125 and 2.123 for the upper and lower stadia hair respectively. If the instrument interval used has an internal interior focusing telescope, what would be the stadia interval factor of the instrument?
The collimation error is 0.01 mm/m, sum of the backsight distances is 1823 m, sum of the foresight distance is 854 m, and the observed elevation difference is −10.853 m. What is the elevation difference with the collimation error accounted for?
Two observation towers A and B are located 300 ft apart, as shown. An object on the ground between the towers is ob-served at point C, and the observer on tower A notes that the angle CAB is 68° 10′. At the same time, the observer on tower B notes that the angle CBA is 72° 30′. Assuming a horizontal surface and towers of equal height, how far is the object from each tower and how high are the towers?
In determining horizontal angle between two points, you lock in and set your horizontal angle to zero on the starting point and rotate towards the end location. In the orientation of the total station, where should we move to get a positive horizontal angle increase after setting it to zero?
A transit with stadia interval factor of 100.8 was set up at point C on the line between points A and B. The following readings were observed: If the distance from the instrument to the focus is 0.38m, determine the following: a) Horizontal distance between A and B. b) Difference in elevation between A and B.
