GeoTable ¶
A spatially-enabled table.
This is a table, or DataFrame
, consisting of named columns with the same length. One of these columns contains a chunked geometry array.
This is similar to a GeoPandas GeoDataFrame
.
geometry ¶
geometry: ChunkedPointArray | ChunkedLineStringArray | ChunkedPolygonArray | ChunkedMultiPointArray | ChunkedMultiLineStringArray | ChunkedMultiPolygonArray | ChunkedMixedGeometryArray | ChunkedGeometryCollectionArray = <attribute 'geometry' of 'geoarrow.rust.core._rust.GeoTable' objects>
Access the geometry column of this table
Returns:
-
ChunkedPointArray | ChunkedLineStringArray | ChunkedPolygonArray | ChunkedMultiPointArray | ChunkedMultiLineStringArray | ChunkedMultiPolygonArray | ChunkedMixedGeometryArray | ChunkedGeometryCollectionArray
–A chunked geometry array
num_columns ¶
num_columns: int = <attribute 'num_columns' of 'geoarrow.rust.core._rust.GeoTable' objects>
Number of columns in this table.
__arrow_c_stream__
method descriptor
¶
__arrow_c_stream__(_requested_schema=None) -> Tuple[object, object]
An implementation of the Arrow PyCapsule Interface. This dunder method should not be called directly, but enables zero-copy data transfer to other Python libraries that understand Arrow memory.
For example, you can call pyarrow.table()
to convert this array
into a pyarrow table, without copying memory.
from_arrow
builtin
¶
from_arrow(input: ArrowStreamExportable) -> Self
Construct this object from existing Arrow data
Parameters:
-
input
(ArrowStreamExportable
) –Arrow array to use for constructing this object
Returns:
-
Self
–Self
