parq_blockmodel.polygon_field.PolygonField

class parq_blockmodel.polygon_field.PolygonField(geometry, name=None)

2D polygon classifier evaluated against block centroids in world XY.

__init__(geometry, name=None)

Methods

__init__(geometry[, name])
evaluate(grid)	Return a boolean mask where centroid XY points intersect polygon geometry.
from_geoparquet(filepath, *, name[, ...])	Create a PolygonField from a named polygon row in a GeoParquet file.
from_shapely(geometry[, name])	Create a PolygonField from shapely polygon geometry.

Attributes

name
geometry

evaluate(grid)

Return a boolean mask where centroid XY points intersect polygon geometry.

Evaluation is strictly 2D in the world XY plane. Z is ignored. Boundary points are classified as inside.

Return type:

ndarray

classmethod from_geoparquet(filepath, *, name, name_column='name', geometry_column=None)

Create a PolygonField from a named polygon row in a GeoParquet file.

Return type:

PolygonField

classmethod from_shapely(geometry, name=None)

Create a PolygonField from shapely polygon geometry.

Return type:

PolygonField
