Creating maps defining the level of acidification by fuzzy analysis

Michal Grec, Matej Horacek, Vilem Novak


Acidification is one of the most important chemical properties of soil and an important indicator of soil quality. Long-term acidification and cation nutrient degradation of forest soils is proving to be the major factor that will limit forest management in the near future. We analyse soil horizons. We use classical cluster analysis and fuzzy cluster analysis to identify areas that have been affected by acidification. The goal of the work is to determine the degree of damage and creating RGB map that would show areas with the same or similar damage caused by acidification. Part of the work is also searching for the areas which have totally different level of acidification (critical points). The result is a map that was created by mixing RGB colors.
