ABSTRACT
Soil properties characteristically vary from location to location and from time to time, and
understanding their spatial and temporal variability has important applications in the soil and
hydrological sciences. Data collected at a number of locations at one point in time (or within
a small time frame) are called a space series, and data collected through time at one location
(or within a small area) are called a time series. The methods for analyzing space and time
series are similar, and are usually referred to as spatial analysis and temporal analysis,
respectively.
