spatial_clip function

Clip values of spatial data.

The function replaces raster values based on different thresholds.

spatial_clip(data, quantile, replace = NA, normalise = TRUE)

Arguments

• data: SpatRaster object, spatial data set to be processed.
• quantile: Numeric value, quantile value below which raster values are clipped.
• replace: Numeric value, replacement value, default is NA.
• normalise: Logical value, optionally normalise values above threshold quantile between 0 and 1. Default is TRUE.

Returns

SpatRaster object, data set with clipped values.

Examples

## load example data set
data(volcano)

## convert matrix to raster object
volcano <- terra::rast(volcano)

## clip values to those > quantile 0.5
volcano_clip <- spatial_clip(data = volcano, 
                             quantile = 0.5)
                                    
## plot clipped data set
terra::plot(volcano_clip)
