摘要：
An important technique used in exploratory analysis of spatial data is moving-window statistics. In this technique, summary statistics of a spatial variable is determined within local neighborhoods (windows) that make up the study site. From these summary statistics, trends and anomalies in local average value and local variability can be examined. This paper presents a FORTRAN-77 program to compute moving-window means and standard deviations with or without window overlap. An example is given and the results are displayed using postplots and scatterplots.
