Levelling5) A person is looking to the horizon, sees a building of height 25 m. What is the least height ofthis building can be seen from the same position if the refraction is neglected?6) A person is looking to a minaret which is touching the horizon when his sighting height is 1.60m and he can see the mid of the minaret if his sighting height is 5.75 m. What is the distancefrom this person to the minaret?7) Via telescope, a surveyor sees top of a tower is touching the horizon and he sees mid of thetower after moving 5000 m toward the tower, what is the height of tower?8) A person sees a minaret is touching the horizon, what is the distance between the person andthe minaret if his sighting height is 1.60 m, and he can see mid of the minaret after moving 4km toward it.9) What is the refraction value in case of a person of sighting height 1.65 m sees a top of buildingis touching the horizon, if you know the distance between him and the building is 19851 m?10) Where the total station at point P, the slope distance and altitude angle to point Q wereobserved as (790.55 m) and (- 05°20'30") respectively. Compute elevation of point P if theelevation of point Q is (45.45 m) and the instrument height and rod reading were equal.11) A theodolite was set up on point A at height (1.57 m), the altitude angle was observed to rodat point B as (2°17'20") and the rod reading was (1.70 m). Then, the theodolite was set up onpoint C at height (1.60 m), the altitude angle to rod at point B was observed as (01°00'40")and the rod reading (1.80 m). Compute the elevation of point B if the horizontal distancebetween A and B equal to horizontal distance between C and B, the elevation of point A (70.42m), and the elevation of point C (86.11 m) (neglect the refraction and curvature error).12) A total station was set up at height (1.58 m) on point Q, the zenith angle and horizontaldistance were observed to reflector (reflector height3D2.89 m) on point P as (269°35'25") and(884.30 m) respectively. Compute the elevation of point Q if the elevation of point P is (78.34m).13) A total station was set up on point F, the altitude angle and the horizontal distance toreflector, which was set up on point H at height (1.76 m), were observed as (3°45') and(870.00 m) respectively. Compute the elevation of point H if the elevation of line of sight was(54.98 m).
