Replace NA values in gridded layers with a fixed value. — spl

This function replaces all NA values in a spatial gridded layer with a fixed value such as for example 0. Accepted input layers are for SpatRaster from the "terra" R-package and stars from the "stars" R-package.

Usage

spl_replaceGriddedNA(obj, value = 0, mask, verbose = FALSE)

Arguments

obj: A SpatRaster, SpatRasterDataset or stars object.
value: A fixed numeric value of which all NA values are to be replaced with (Default: 0).
mask: An optional SpatRaster object used instead of the value.
verbose: Be chatty about what is processed (Default: FALSE).

Value

A object of the same type as the input but with no-data values replaced with 'value'.

Details

Required inputs are a single "obj" gridded data object and a numeric value. In addition an optional mask layer can be provided that to use a mask. In this case all no-data values a replaced with the value in this mask.

# Example
s <- terra::rast(system.file("ex/logo.tif", package="terra"))
s[sample(1:terra::ncell(s), 100)] <- NA
sfill <- spl_replaceGriddedNA(s, value = 100)
terra::plot(sfill)
