inspectDataset()
returns information about the format and content
of a dataset. The function first calls identifyDriver()
, and then opens
the dataset as raster and/or vector to obtain information about its content.
The return value is a list with named elements.
inspectDataset(filename, ...)
filename |
Character string containing the name of the file to access. This may not refer to a physical file, but instead contain information for the driver on how to access a dataset (e.g., connection string, URL, etc.) |
... |
Additional arguments passed to |
A list with the following named elements:
$format
: character string, the format short name
$supports_raster
: logical, TRUE
if the format supports raster data
$contains_raster
: logical, TRUE
if this is a raster dataset or the
source contains raster subdatasets
$supports_subdatasets
: logical, TRUE
if the format supports raster
subdatasets
$contains_subdatasets
: logical, TRUE
if the source contains subdatasets
$subdataset_names
: character vector containing the subdataset names, or
empty vector if subdatasets are not supported or not present
$supports_vector
: logical, TRUE
if the format supports vector data
$contains_vector
: logical, TRUE
if the source contains one or more
vector layers
$layer_names
: character vector containing the vector layer names, or
empty vector if the format does not support vector or the source does not
contain any vector layers
Subdataset names are the character strings that can be used to
instantiate GDALRaster
objects.
