GDAL Vector Driver Creation Options

Accessors for a driver's creation options, parsed from both the dataset-level (DMD_CREATIONOPTIONLIST, --co) and layer-level (DS_LAYER_CREATIONOPTIONLIST, --lco) metadata. Use sub_type to restrict to one level.

• gdal_vector_driver_creation_opts(): the creation-option table for driver.

• gdal_vector_driver_creation_opts_defaults(): name to default (all, or one when opt_name given).

• gdal_vector_driver_creation_opts_values(): name to allowed values (only constrained options).

• gdal_vector_driver_creation_opts_types(): name to data_type.

Usage

gdal_vector_driver_creation_opts(driver, sub_type = NULL)

gdal_vector_driver_creation_opts_defaults(
  driver,
  opt_name = NULL,
  sub_type = NULL
)

gdal_vector_driver_creation_opts_values(
  driver,
  opt_name = NULL,
  sub_type = NULL
)

gdal_vector_driver_creation_opts_types(driver, sub_type = NULL)

Arguments

driver

Character scalar GDAL driver short name.

sub_type

Optional creation level to restrict to: "dataset" or "layer".

opt_name

Optional single option name. When supplied, returns the value for that option only; otherwise returns the full named result.

Value

A tibble::tibble(), named character vector, or named list (see gdal_vector_driver_opts()).
