What are three sources of error that can happen in traverses? Give specific examples and make
an estimate as to the amount of error likely for each source.
What advantages are there to performing an accurate traverse in an area before surveying?
Why is it important to tie into monuments when performing a traverse?
Solution
Some sources of error in running a traverse are:
1.Poor selection of stations, resulting in bad sighting conditions caused by alternatesun and
shadow, visibility of inly the rod’s top, line of sight passing too close to theground, lines that are
too short, and sighting into the sun.
2.Errors in observations of angles and distances.
3.Failure to observe angle an equal number of time directs and reversed.
The advantages of performing an accurate traverse in an area are as follows:
1. The main advantage is that it takes much less effort for traversing than chain surveying.
2. The accuracy of traverse surveying is much more than the chain surveying.
3. The closed traverse is suitable for locating the boundaries of lakes, woods, etc and for survey
of large areas. the open traverse is suitable for surveying a long narrow strip of land as required
for a road of canal or the coast line.
4. Difficult terrains can be covered.
5. Accurate measurement of angles leads to accurate measurement of elevations and distances.
6. The error accuring due to sagging of chains and human effor is minimized.
It is important to tie the monuments when performing traverse because monuments acts as Bench
Marks. Bench marks are fixed reference points of known elevation. as the monuments are not
supoosed to change or alter due to their importance they can be used as bench marks.
