This involves the adjustment of angles by equal amounts and the application of the side equation. Provided all angles (or directions) have been observed to a high standard, this form of adjustment may suffice for small figures.
How do you calculate the RL level?
Reduced level (R.L.) = height of collimation (H of C) – foresight (F.S.) reduced level (R.L.) = height of collimation (H of C) – intermediate sight (I.S.)
What is the formula for levelling?
Sum of rise – sum of fall = last R. L. – first R.L.
What are the 4 types of triangulation?
The four methods of triangulation are as follows : Data triangulation Investigator triangulation Theory triangulation Methodological triangulation
What is called triangulation?
Triangulation is a type of survey which starts at a baseline joining two positions with a known distance, and grows by adding sides to form a triangle, measuring the angles formed always exceeding 20° and shaping a network of connected triangles whose sides have 'calculated' distances.
