The Arrow reader supports reading Arrow and Parquet -formatted data as written by writers.arrow, although it should support point clouds written by other writers too if they follow either the GeoArrow or GeoParquet specification.

Caveats:

• Which schema is read is chosen by the file name extension, but can be overridden with the format option set to geoarrow or geoparquet

Options

filename

Arrow GeoArrow or GeoParquet file to read [Required]

format

geoarrow or geoparquet option to override any filename extension hinting of data type [Optional]
