mosaic_rasters: Mosaic raster files using GDAL Utilities

Description

Mosaic raster files using GDAL Utilities

Usage

mosaic_rasters(gdalfile, dst_dataset, output.vrt = NULL,
  output_Raster = FALSE, ...)

Arguments

gdalfile

Character. Input files (as a character vector) or a wildcard search term (e.g. "*.tif")

dst_dataset

Character. The destination file name.

output.vrt

Character. Output VRT file. If NULL a temporary .vrt file will be created.

output_Raster

Logical. Return output dst_dataset as a RasterBrick?

...

Parameters to pass to gdalbuildvrt and gdal_translate.

Value

• Either a list of NULLs or a list of RasterBricks depending on whether output_Raster is set to TRUE.

Details

This function mosaics a set of input rasters (gdalfile) using parameters found in gdalbuildvrt and subsequently exports the mosaic to an output file (dst_dataset) using parameters found in gdal_translate. The user can choose to preserve the intermediate output.vrt file, but in general this is not needed.
