Question

In the double application of principle of reversion the apparent error is

Answer 1

In the double application of principle of reversion, the apparent error is four times the true error.

Explanation:

• Surveying can be defined as the process of determining the relative positions of the various objects on the earth’s surface.  

• This can be done by measuring the ‘horizontal distance’ between them and we will prepare a map to any of the suitable scale.  

• Usually, the measurements are taken in horizontal scale. Surveying is the art of computing the ‘relative positions’ of the points on or above the ‘surface of the earth’.  

• In the reversion principle, the apparent error is 4 times the true error.
