GeoParquet Open Options

Source: R/gpq_opts.R
gpq_open_opts.Rd

Construct a gdal_open_opts() object for the Parquet (GeoParquet) driver.

Usage

gpq_open_opts(
  geom_possible_names = NULL,
  crs = NULL,
  lists_as_string_json = NULL,
  ...,
  .set_defaults = FALSE
)

Arguments

geom_possible_names

Value for GEOM_POSSIBLE_NAMES (GDAL >= 3.8). Comma-separated list of candidate geometry column names, used only for files without GeoParquet metadata. GDAL default "geometry,wkb_geometry,wkt_geometry".

crs

Value for CRS (GDAL >= 3.8). Set or override the CRS of geometry columns, typically "AUTH:CODE" (e.g. "EPSG:4326"), or a PROJ/WKT CRS string.

lists_as_string_json

Value for LISTS_AS_STRING_JSON (GDAL >= 3.12.1; logical -> "YES"/"NO"). Report lists of strings/integers/reals as String(JSON) fields. GDAL default "NO".

...

Additional NAME = value options passed through verbatim alongside the typed arguments. They are coerced and validated against the driver metadata in the same way, and take precedence over a typed argument that sets the same option.

.set_defaults

Logical. If TRUE, options left unset (NULL) are filled with the driver's documented GDAL metadata defaults (via the relevant gdal_vector_driver_*_opts_defaults()); user-supplied values always take precedence. Defaults to FALSE.

Value

A gdal_open_opts() object for the Parquet driver.
