Native interface to gdal utils

Usage

gdal_utils(
  util = "info",
  source,
  destination,
  options = character(0),
  quiet = !(util %in% c("info", "gdalinfo", "ogrinfo", "vectorinfo", "mdiminfo")) ||
    ("-multi" %in% options),
  processing = character(0),
  colorfilename = character(0),
  config_options = character(0),
  read_only = FALSE
)

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), ogrinfo (requiring GDAL 3.7), footprint (requiring GDAL 3.8)
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")
config_options: named character vector with GDAL config options, like c(option1=value1, option2=value2)
read_only: logical; only for ogrinfo: if TRUE, source is opened in read-only mode

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.
