rfillspgaps: Close gaps of a grid or raster Layer data

In meteo: RFSI & STRK Interpolation for Meteo and Environmental Variables

Close gaps of a grid or raster Layer data

Description

The function close gaps of a raster data by using IDW.

Usage

rfillspgaps(rasterLayer,
            maskPol=NULL,
            nmax =50,
            zcol=1,
            ...)

Arguments

rasterLayer	SpatRaster-class, RasterLayer-class, SpatialGrid-class or SpatialPixels-class; Raster that contains NAs.
maskPol	sf-class, SpatVector-class, SpatialPolygons or SpatialPolygonsDataFrame; Area of interest to spatially fill rasterLayer missing values and to mask rasterLayer.
nmax	see krige, idw function.
zcol	integer or character; variable column name or number showing position of a variable in rasterLayer to be interpolated.
...	arguments passed to krige, idw function.

Value

raster object with NA replaced using IDW in rasterLayer format.
