Concept: Principle of surveying: 1) Whole to part: ● In working from whole to part, the error will localize and prevent the accumulation of error while working from part to whole (figure A), the error will accumulate. ● Hence more errors in working from part to whole.
Figure A - Woking from part to Whole 2) Location w.r.t at least 2 well-defined control points: ● The location of a point should be respected to at least 2 well-defined control points. ● To establish a station/point, a minimum of one angular and one linear or two linear or two angular measurements are necessary. ● The following different conditions can be observed in the figure below.
∴ Working from part to whole is not correct for the principle of surveying.
