This function provides an interface mirroring that of the GDAL
command-line app gdalinfo. For a description of the
utility and the arguments that it takes, see the documentation at
https://gdal.org/programs/gdalinfo.html.
Usage
gdalinfo(
datasetname,
...,
json,
mm,
stats,
approx_stats,
hist,
nogcp,
nomd,
norat,
noct,
nofl,
checksum,
proj4,
listmdd,
mdd,
wkt_format,
sd,
oo,
IF,
dryrun = FALSE,
config_options = character(0),
quiet = FALSE
)Arguments
- datasetname
Path to a GDAL-supported readable datasource.
- ...
Here, a placeholder argument that forces users to supply exact names of all subsequent formal arguments.
- json, mm, stats, approx_stats, hist, nogcp, nomd, norat, noct
See the GDAL project's gdalinfo documentation for details.
- nofl, checksum, proj4, listmdd, mdd, wkt_format, sd, oo, IF
See the GDAL project's gdalinfo documentation for details.
- dryrun
Logical (default
FALSE). IfTRUE, instead of executing the requested call to GDAL, the function will print the command-line call that would produce the equivalent output.- config_options
A named character vector with GDAL config options, of the form
c(option1=value1, option2=value2). (See here for a complete list of supported config options.)- quiet
Logical (default
FALSE). IfTRUE, suppress printing of output to the console.
Value
Silently returns a character vector containing the information returned by the gdalinfo utility.
