In eseis: Environmental Seismology Toolbox

Clip values of spatial data.

Description

The function replaces raster values based on different thresholds.

Usage

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.

Value

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)
