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]
- count

- override_srs

- default_srs
