9 Before wide-spread of computers and invention of sample planning
10 methods with random sampling, people took samples on the "most
11 typical" points of territory, and then draw isolines by hand,
12 taking into account type of vegetation, soil etc, known to them from
13 first-hand field experience.
16 This give better results than regular sampling grids - less samples and
17 more information about actual field of concentration of some element.
20 Being taught in the University these old pre-computer era methods, I
21 thought about using them in GIS.
24 Idea of method is quite simple: we repesent qualitive difference between
25 areas as set of boolean variables - indicators, and compute influence of
26 each of them using least squares method.

30 This is my first paper ever published in the magazine. It was
31 published in Vestink MGU, Geography Series in 1991.
