In geostatistics, spatial difference analysis based on variogram principles serves as a powerful tool for spatial data investigation. This analytical approach effectively reveals spatial variability patterns and underlying trends within geographic datasets. The MATLAB implementation employs key functions such as variogram for calculating spatial autocorrelation and kriging for optimal interpolation. MATLAB's comprehensive computational environment provides robust tools for data processing, statistical analysis, and geospatial visualization. By leveraging MATLAB's geostatistical toolbox, practitioners can implement variogram modeling through variogramfit to characterize spatial structure, followed by krig functions for spatial prediction. This integration significantly enhances processing efficiency while ensuring statistically sound and reliable results through proper semivariogram analysis and cross-validation techniques.
