FlatGeobuf Open Options

Construct a gdal_open_opts() object for the FlatGeobuf driver. Only options you supply are emitted; values are validated against the driver's registered metadata.

Usage

fgb_open_opts(verify_buffers = NULL, ..., .set_defaults = FALSE)

Arguments

verify_buffers

Value for VERIFY_BUFFERS. Logical TRUE/FALSE (coerced to "YES"/ "NO") controlling whether flatbuffer integrity is verified on read. "YES" (the GDAL default) guards against corrupt data at a small performance cost; "NO" is faster but unsafe on malformed files. NULL (default) leaves it unset.

...

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 FlatGeobuf driver.
