In snapKrig: Fast Kriging and Geostatistics on Grids with Kronecker Covariance

Convert "sk" grid to SpatRaster

Description

Convert "sk" grid to SpatRaster

Usage

sk_export(g, template = "terra")

Arguments

g	any object accepted or returned by sk
template	character or RasterLayer/SpatRaster to set output type Converts a vector or matrix to a SpatRaster or RasterLayer. Multi-layer outputs are supported for terra but not raster.

Value

a RasterLayer or SpatRaster containing the data from g (or a sub-grid)

Other exporting functions: sk_coords()

Examples

if( requireNamespace('raster') ) {

# open example file as RasterLayer
r_path = system.file('external/rlogo.grd', package='raster')
r = raster::raster(r_path, band=1)
g = sk(r)

# convert back to RasterLayer and compare
r_from_g = sk_export(g, 'raster')
print(r)
print(r_from_g)

# NOTE: layer name, band number, and various other metadata are lost
all.equal(r_from_g, r)

}

# same with terra
if( requireNamespace('terra') ) {

# convert all layers
r = terra::rast(r_path)
g = sk(r)
r_from_g = sk_export(g)

# NOTE: various metadata are lost
all.equal(r_from_g, r)

}
