## Approximation of functions of root mean square errors of land parcels areas to determine their allowable value

The purpose of this article is the research of results of approximation of functions of calculation of the meansquare errors of land parcels areas to determine such approximation function, which would allow most accurately calculate the permissible values of mean square errors depending on the size and elongation of land parcel. Methods. To meet the goal an approximation of functions by the method of least squares was performed. Two functions were used for approximation – the natural logarithm and power, as well as the evaluation of the accuracy was done.
