This is a good opportunity for students to be involved in a real life situation. Back to Top Item 9. Surveying assignment ideas Surveying assignment ideas with use of surveying equipment such as a dumpy level, plane table and alidade, compasses and tapes. A sample diagram is shown below. Calculations require use of sine and cosine.
Surveyors check and double-check their recorded measurements and so it is with a closed traverse.
They call the error in measurement misclosure and have an acceptable value for this. To calculate the misclosure the difference between the known sum of the interior angles and the recorded sum of the interior angles is calculated. The recorded sum is the sum of the measurements taken by the surveyor performing the traverse. Apply this check to closed traverses. Explore the patterns that give rise to the rules.
