b. The surveyor's first reading was to TBM 41 with reading 5.76, she then took the following readings (see table below) and closed the survey with reading 5.77 to TBM 41. Station 1 2 Rod reading 2.21 3.54 5.71 4.52 4.85 TP1 6 7 8 9 3 4 5 2.58 12.55 14.65 8.26 16.84 11.54 21.55 5.11 5.48 TP2 4.84 5.42 TP3 6.24 11- TP4 5.57 10 0.87 6.31 BM B BM A Calculate the elevation of all the points she surveyed and the misclosure in the survey.

A line was measured three times and yield the following results: 856.42, 856.69 and 856.12 m. Determine the probable error of the mean.

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

SITUATION 3. a) The base and altitude of a triangle lot were measured to have certain probable errors of 314.60 0.16 and 92.60 = 0.14, compute the probable error of the resulting computation. (3- b) The following sides of a rectangle and its probable errors are 120.40 0.04 and 360.50 ± 0.08 respectively. Compute the probable errors of the sum of the sides (perimeter) of rectangle. (3r c) The probable error of the mean of 6 observation is 0.043 and the most probable value of the measurement is 860 m compute the relative precision. C

Surveying Question: A differential leveling circuit starts at benchmark Concrete Benchmark (Elevation=232.051m) goes out to an unknown benchmark and then continues to a known control point (Elevation=227.975m). Two turning points are used with the measurements included in the attached table. Determine the elevation of the unknown benchmark  Determine the order and class of the survey. For First order Class 1: Allowable Error= +/- 4(K)1/2 Range of Constant= m less than/equal to 4 For First Order Class 2: Allowable error= +/- 5(K)1/2 Range of constant= m greater than/equal to 4, and m less than equal to 5 (between 4 and 5) For Second Order Class 1:  Allowable error = +/- 6(K)1/2 Range of Constant = m greater than/equal to 5, and m less than equal to 6 (between 5 and 6) For Second Order Class 2: Allowable error = +/- 8(K)1/2 Range of Constant = m greater than/equal to 6, and m less than equal to 8 (between 6 and 8) For Third Order, Any Class: Allowable Error = +/-12(K)1/2 Range…
