Work from whole to part:
- The main idea of working from whole to part is to localize the error and prevent their accumulation.
- The survey area is covered with the simplest possible framework of high-quality measurements. If the rest of the survey work is carried out within this area, the possible accumulation of errors can be contained.
- Major control points are established with higher precision and the minor control points are established with less precision as compared to major control points.
- If we work from part to whole the errors accumulate and expand to a greater magnitude in the process of expansion of the survey.
Hence statements (i) and (iii) are correct.
