Usage

mosaic_input(mosaic, ...)

mosaic_export(mosaic, filename, overwrite = FALSE, ...)

Arguments

mosaic	For mosaic_input(), a file path to the raster to imported, a matrix, array or a list of SpatRaster objects. For mosaic_export(), an SpatRaster object.
...	Additional arguments passed to terra::rast() (mosaic_input()) or terra::writeRaster() (mosaic_output())
filename	character. The Output filename.
overwrite	logical. If TRUE, filename is overwritten.

Details

• mosaic_input() is a simply wrapper around terra::rast(). It creates a SpatRaster object from scratch, from a filename, or from another object.

• mosaic_export() is a simply wrapper around terra::writeRaster(). It write a SpatRaster object to a file.

Value

• mosaic_input() returns an SpatRaster object.

• mosaic_export() do not return an object.

Examples

library(pliman)

# create an SpatRaster object based on a matrix
x <- matrix(1:20, nrow = 4, ncol = 5)
rast <- mosaic_input(x)
mosaic_view(rast, viewer = "base", axes = TRUE)

# create a temporary filename for the example
f <- file.path(tempdir(), "test.tif")
mosaic_export(rast, f, overwrite=TRUE)
list.files(tempdir())
