Pedometrics

Pedometrics is the application of mathematical and statistical methods for the study of the distribution and genesis of soils.

Pedometrics is a neologism derived from the Greek roots "pedos", soil and, "metron", measurement. Measurement in this case is restricted to mathematical and statistical methods as it relates to pedology, the branch of soil science that studies soil in its natural setting.

Pedometrics addresses soil related problems when there is uncertainty due to deterministic or stochastic variation, vagueness and lack of knowledge of soil properties and processes. It relies upon mathematical, statistical, and numerical methods and extends to numerical approaches to classification to deal with a supposed deterministic variation. Simulation models incorporate uncertainty by adopting chaos theory, statistical distribution, or fuzzy logic.

Pedometrics addresses pedology from the perspective of emerging scientific fields such as wavelets analysis, fuzzy set theory and data mining in soil data modelling applications. The advance of pedometrics is also linked to improvements in remote and close-range sensing. [cite journal | last = Peter A. | first = Burrough | coauthors = Johan Bouma and Scott R.
