Description

Describe the properties of spatial data in a file as generated with the "GDALinfo" tool.

Usage

## S4 method for signature 'character'
describe(x, sds=FALSE, meta=FALSE, parse=FALSE, options="", print=FALSE, open_opt="")

desc(x)

Arguments

x

character. The name of a file with spatial data. Or a fully specified subdataset within a file such as "NETCDF:\"AVHRR.nc\":NDVI"
sds

logical. If TRUE the description or metadata of the subdatasets is returned (if available)
meta

logical. Get the file level metadata instead
parse

logical. If TRUE, metadata for subdatasets is parsed into components (if meta=TRUE)
options

character. A vector of valid options (if meta=FALSE) including "json", "mm", "stats", "hist", "nogcp", "nomd", "norat", "noct", "nofl", "checksum", "proj4", "listmdd", "mdd <value>" where <value> specifies a domain or 'all', "wkt_format <value>" where value is one of 'WKT1', 'WKT2', 'WKT2_2015', or 'WKT2_2018', "sd <subdataset>" where <subdataset> is the name or identifier of a sub-dataset. See https://gdal.org/programs/gdalinfo.html. Ignored if sds=TRUE
print

logical. If TRUE, print the results
open_opt

character. Driver specific open options

Value

character (invisibly, if print=FALSE)

Examples

f <- system.file("ex/elev.tif", package="terra")
describe(f)
describe(f, meta=TRUE)
#g <- desc(f, options=c("json", "nomd", "proj4"))
#cat(g, "\n")
