Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- In whole to part, the error is localized as it prevents accumulation of error and,
- In part to whole, the error is expanded.
The fundamental principles of plane surveying are:
1. Location of a point by measurement from two points of reference:
- Two control points are selected in an area and the distance between them is measured accurately.
2. Working from whole to the part:
- Major control points are selected and measured first with a high degree of precision, minor details can be collected later on even with less degree of precision. In this manner, errors involved in minor detailing will be compensating and will not affect the major dimensions.
Note:
- The main idea of working from whole to part is to localize errors and prevent their accumulation.
- On the contrary, working from part to whole, the errors accumulate and expand to a greater magnitude and the survey work becomes uncontrollable at the end.
