calculate_spatial_correlation: Calculate spatial correlation between raster layers

In geospatialsuite: Comprehensive Geospatiotemporal Analysis and Multimodal Integration Toolkit

Calculate spatial correlation between raster layers

Description

Calculate spatial correlation between two raster layers using various methods. Supports pixel-wise correlation and local correlation analysis.

Usage

calculate_spatial_correlation(
  raster1,
  raster2,
  method = "pearson",
  local_correlation = FALSE,
  window_size = 3
)

Arguments

raster1	First raster layer
raster2	Second raster layer
method	Correlation method: "pearson", "spearman", "kendall"
local_correlation	Calculate local correlation using moving window
window_size	Window size for local correlation (in pixels)

Value

Correlation coefficient or SpatRaster of local correlations

Examples

## Not run: 
# These examples require external data files not included with the package
# Global correlation between NDVI and soil nitrogen
correlation <- calculate_spatial_correlation(ndvi_raster, nitrogen_raster)

# Local correlation with moving window
local_corr <- calculate_spatial_correlation(
  ndvi_raster, nitrogen_raster,
  local_correlation = TRUE,
  window_size = 5
)

## End(Not run)
