ABSTRACT
The weight coefficient QFF is a function of the weight coefficients of the adjusted observations and the distances and/or the angles of the mathematical figure, which expresses the conditions to which the original observations are adjusted. Consequently, not only the precision of the adjusted observations but also the actual values of these distances and/or angles must be considered in order to obtain an optimum value for the weight coefficient QFF, and subsequently a minimal variance. The precision of the fundamental measurements and of other necessary data can be estimated for the particular measuring equipment available for the project. By tracing the optimum conditions of the geometrical figures which correspond to the minimum values of the weight coefficients, rules can be set down for reconnaissance. After the project is surveyed, the actual precision can be calculated and submitted to statistical tests with regard to its consistency with the anticipated value.
