Cartographic method of surface characteristics analysis

Abstract

A wide range of investigations is based on analysis of experimental data, which are represented as a function of two variables (height of the relief h(x, y), microhardness, color, etc.). In the studying of process or phenomenon change of these functions after the experiment is of great interest. On numerous occasions the main problem in comparative analysis of the data sets is the absence of a natural reference level (such as sea level), respect to which changes of the surface characteristics can be determined. We suggest the possible algorithm of determining of the reference level. Also there is its comparison with the standard methods in this paper. This method was used for AFM data processing in the study of effects of natural and artificial factors on the surface of human tooth enamel. The paper presents the main results of this research and shows the necessity of additional data processing using the developed method.
