In brief, stationarity is a condition that shows whether the data has a constant mean and variance in each location. Stationarity is widely used in time series function, nevertheless we also need to know its application in terms of spatial data estimation.

WebIn the most intuitive sense, stationarity means that the statistical properties of a process generating a time series do not change over time. It does not mean that the series does not change over time, just that the way it changes does not itself change over time.
