cuspa.io.from_geoarrow

cuspa.io.from_geoarrow(

obj: Any,

*,

geometry: str | None = None,

dtype: Any = None,

) → Polygons

Convert a GeoArrow Polygon/MultiPolygon table or array to Polygons.

Parameters:

obj

A pyarrow Table/Array/ChunkedArray or a GeoPandas to_arrow(geometry_encoding="geoarrow") result. Polygon and MultiPolygon arrays are supported. WKB columns are rejected because they require geometry parsing.

geometry

Geometry column name when obj is a table. If omitted, the first GeoArrow geometry column is used, falling back to "geometry".

dtype

Coordinate dtype for the GPU buffer. Defaults to cupy.float32.
