Native interface to gdal utils

gdal_utils(
  util = "info",
  source,
  destination,
  options = character(0),
  quiet = !(util %in% c("info", "mdiminfo")),
  processing = character(0),
  colorfilename = character(0)
)

Arguments

util: character; one of info, warp, rasterize, translate, vectortranslate (for ogr2ogr), buildvrt, demprocessing, nearblack, grid, mdiminfo and mdimtranslate (the last two requiring GDAL 3.1)
source: character; name of input layer(s); for warp, buidvrt or mdimtranslate this can be more than one
destination: character; name of output layer
options: character; options for the utility
quiet: logical; if TRUE, suppress printing the output for info and mdiminfo, and suppress printing progress
processing: character; processing options for demprocessing
colorfilename: character; name of color file for demprocessing (mandatory if processing="color-relief")

Value

info returns a character vector with the raster metadata; all other utils return (invisibly) a logical indicating success (i.e., TRUE); in case of failure, an error is raised.
