List of top Geomatics Engineering Questions on Principles of surveying

For a reconnaissance survey, it is necessary to obtain vertical aerial photographs of a terrain at an average scale of 1: 13000 using a camera. If the permissible flying height is assumed as 3000 m above a datum and the average terrain elevation is 1050 m above the datum, the required focal length (in mm) of the camera is

What is the CORRECT match between the survey instruments/parts of instruments shown in the table and the operations carried out with them ?

Instruments/Parts of instruments		Operations
P	Bubble tube	i	Tacheometry
Q	Plumb bob	ii	Minor movements
R	Tangent screw	iii	Centering
S	Stadia cross-wire	iv	Levelling

To finalize the direction of a survey, four surveyors set up a theodolite at a station P and performed all the temporary adjustments. From the station P, each of the surveyors observed the bearing to a tower located at station Q with the same instrument without shifting it. The bearings observed by the surveyors are 30° 30' 00", 30° 29′ 40′′, 30° 30′ 20′′ and 30° 31′ 20′′. Assuming that each measurement is taken with equal precision, the most probable value of the bearing is

A surveyor observes a zenith angle of 93° 00' 00" during a theodolite survey. The corresponding vertical angle is
