I need Answer of A only A. A tachometric surveying was conducted to obtain some readings forinaccessible points, where it was found that the multiplying and additiveconstants are 98 and 0.1, respectively. The instrument was setup at point C and the readings listed in the table were taken while the staff was held vertically. Calculate the horizontal distance between BM and station D. Also, calculate the reduced level of station D. Figure 1 shows a schematic view of the site.
Three triangulation stations A, C and E are points on the shore whose position were observed from X. The angles were measured using a sextant from the boat at X to the three triangulation stations. The following data were recorded during the survey procedure: Distance AC = 700m Distance CE = 680m Angle ACE = 148o Angle AXC = 45o Angle CXE = 35o Angle CAX = 70o a.) Compute the angle CEX. b.) Compute the distance AX. c.) Compute the distance XE.

Problem In a topographic survey undertaken by Karman Sury. Corp. before any leveling is conducted, the engineers usually check whether the engineers level is In perfect adjustment. A two peg test is used to check whether the line of sight is in perfect adjustment and the following rod readings are taken, with instrument set up near A, on A is 1.623 m and foresight reading on B is 2.875 m with the instrument set up near B backsight on B is 1.622 m and a foresight on A is 0.362 m A. Compute the difference in elevation between A and B . B. What should be the correct rod reading on A to give a level line of sight with the instrument still set up at B? C. What should have been the reading on B with the instrument at A to give a level line of sight?
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…
