 In recent years, digital soil mapping has faced rapid development of new and economic methods, mainly due to the increasing sources of auxiliary maps. The main objective of this research was to develop a methodology for pedometric mapping that can be used to bridge gaps between the mechanistic pedometric and conventional techniques. The thesis covers seven methodological aspects of soil mapping: sampling, pre-processing, photo-interpretation, interpolation, visualisation, organisation and quality control. The proposed pedometric mapping methodology enhances the practice of soil mapping making the soil maps more objective, detailed and more compatible for integration with other environmental geo-data. There is no need to use the concept of soil mapping units or use double-crisp soil maps anymore. On the other hand, instead of abandoning photo-interpretation, soil classification or empirical knowledge on soils, these methods can be successfully integrated with pedometric techniques.
