xdem.DEM.polygonize

DEM.polygonize(target_values='all', data_column_name='id')

Polygonize the raster into a vector.

Parameters:

• target_values (int | float | integer[Any] | floating[Any] | tuple[int | float | integer[Any] | floating[Any], int | float | integer[Any] | floating[Any]] | list[int | float | integer[Any] | floating[Any]] | ndarray[tuple[Any, ...], dtype[floating[Any] | integer[Any]]] | Literal['all']) – Value or range of values of the raster from which to create geometries (defaults to “all”, for which all unique pixel values of the raster are used).

• data_column_name (str) – Data column name to be associated with target values in the output vector (defaults to “id”).

Return type:

Vector

Returns:

gu.Vector containing the polygonized geometries associated to target values.
