1. The surveying team at UTM can make taping measurements with an error of±0.03 ft per 100-ft tape length. What is the error associated with taped distance of700 ft?2. Since the mean is computed from individual observed values, each of whichcontains an error, the mean is also subject to error. We can assume that the error orthe mean is =Em= Eseries/nuWhat will be the 90% error of the mean for a 25 observations having a standarddeviation of +0.0495 ft3. Determine the weighted mean for the following angles88° 54'21", wt 3,88° 54'55", wt 5,88° 54'11", wt 6,88° 53'58", wt 4,

An elevation must be established on a benchmark on an island that is 2536.98 ft from the nearest benchmark on the island’s shore. The surveyor decides to use a total station that has a stated distance measuring accuracy of (3 mm +3 ppm) and a vertical compensator accurate to within 0.4”. The height of instrument was 5.37 ft with an estimated error of 0.05 ft. The prism height was 6.00 ft with an estimated error of 0.02 ft. The single zenith angle is read as The estimated errors in instrument and target centering are 0.003 ft. If the elevation of the occupied benchmark is 632.27 ft, what is the corrected benchmark elevation on the island? (Assume that the instrument does not correct for Earth curvature and refraction.) After completing the job, the surveyor discovered that the instrument had a vertical indexing error that caused the sight line to be inclined by 15. (a) How much error would be created in the elevation of the island benchmark if the indexing error were ignored? (b) What…
P Give suitable examples as you discuss how errors in surveying activities are classified. The three angles of a triangle were measured using a triangulation scheme, and their mean values were reported as 50° 48′ 18′′, 64° 2036", and 64° 5100".Each of these means has a standard deviation of 4 according to analysis of each set.The angles were measured again at a later time under better lighting, resulting in mean values of 64° 20′ 39", 64° 50' 58", and 50° 48' 20" prime prime Each value's standard deviation was 2 n. Determine the most probable values of the angles
