align_rasters: Aligns raster files

In gdalUtils: Wrappers for the Geospatial Data Abstraction Library (GDAL) Utilities

Description

Aligns a raster to a reference raster.

Usage

align_rasters(
  unaligned,
  reference,
  dstfile,
  output_Raster = FALSE,
  nThreads = 1,
  projres_only = FALSE,
  verbose = FALSE,
  ...
)

Arguments

unaligned	Character. The filename of a raster to be aligned to the reference raster.
reference	Character. The filename of a raster to be used as the reference for the alignment. Syncing will use the reference's projection, resolution, and extent.
dstfile	Character. The filename of the synchronized output file.
output_Raster	Logical. Return output dst_dataset as a RasterBrick?
nThreads	Numeric or Character. If numeric, the number of threads to use. Setting to > 1 enables multithreaded execution. Can also be "ALL_CPUS" to use all available CPUS. Default is 1.
projres_only	Logical. Matches projection and pixel resolution only, but leaves the spatial extent unchanged. Useful for mosaicking. Default = FALSE.
verbose	Logical. Enable verbose execution? Default is FALSE.
...	parameters to be passed to gdalwarp (e.g. resampling approach).

Details

Aligns a raster to the extent and projection of a reference raster and matches the resolution of the reference raster. This is helpful in preparing multiple files of different projections, resolutions, extents, and rotations for performing map algebra or change detection.

Value

Either NULL or a RasterBricks depending on whether output_Raster is set to TRUE.
