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.

added together to get the total length).
a.
what is the estimated total error?
b. what is the probable total error if the random error is ± 0.006 m per length?
3.

for each 30.000 m distance. What estimated total error should be expected if a distance of 1400 m
is measured?
4. It is desired to tape a distance of 360 m with a total estimated probable error of not more than ±
0.006 m.
