If a certain EDM instrument has an accuracy capability of ±( 12 mm + 2 ppm2), what is the precision of measurements, in terms of parts per million, for line lengthsof: (a) 20.000 m, (b) 200.000 m, (c) 2000.000 m? (Assume that the instrument andtarget miscentering errors are equal to zero.)

Q1). The following consecutive readings were taken along a straight line from station (11+090) to station (12+015). The instrument has been changed after third, fifth, eighth and welfth readings. The readings are as bellows: B D 0.680, 1.455, 1.855, 2.330, 2.885, 3.380, 1.055, 1.680, 2.265, 3.540, 0.835, 0.945, 1.530 and 2.250, first and last point are a bench marks having elevations 50.25m and 50.81 m respectively. 44.8 1- Draw page of level book and enter the above data. 2- Find elevation of points by height of instrument method. 3- Check your calculation. 4- Determine the gradient of the line joining the first and last point. 5- Determine loop closure and adjust calculated elevations. -5.408
