Mosaic a list of spatial layers together.

Particular for large spatial files, it is often impractical to process the entire layer as single file. Instead such a file could be split in smaller chunks and processed as such.

A common issue then is to reconstruct a spatial file of the original extent. This function takes a list of filenames as input and mosaics them together using a 'vrt' file format.

Usage

spl_mosaicTiffs(files, ofname = NULL, tempdir = NULL, dt = "INT2S", ...)

Arguments

files: A character vector with filenames of spatial files.
ofname: A character where the output should be written (Default: NULL).
tempdir: A character with a temporary folder that must exist (Default: NULL).
dt: A character with the output datatype of the spatial file (Default: "INT2S").
...: Any other parameters passed to writeRaster.

Value

A SpatRaster or just a file.

Details

This function by default uses the 'gdalUtilities' R-package and tools for most of the projections.
