5. In five trials of walking along a 90-m course on fairly level ground, a pacer for a survey party counted 51, 52.5, 51.5, 52.5 and 51.5 strides respectively. He then started walking an unknown distance XY in four trials which were recorded as follows: 88.5, 89, 88, and 87 strides. Determine the following: a.) Pace factor of the pacer b.) Length of line XY ci Percentage of error in the measurement if the taned length of XY is 150. 5 meters

Methods of Surveying

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plotting them on a map of any appropriate scale. Accuracy can be achieved by using the latest instruments like a theodolite, tachometer, etc. Leveling is a subdivision of surveying where the objective is to locate the elevation of objects considering a datum level.
