delete(feature_id, geometry: Point | Polygon | LineString | MultiPoint | MultiPolygon)[source]#
insert(feature_id: int, geometry: Point | Polygon | LineString | MultiPoint | MultiPolygon | MultiLineString) → None[source]#

Inserts a valid shapely geometry in the index

Arguments:

feature_id (int): ID of the geometry being inserted geo (Shapely.geometry): Any valid shapely geometry

nearest(geo: Point | Polygon | LineString | MultiPoint | MultiPolygon, num_results) → List[int][source]#

Finds nearest neighbor for a given geometry

Arguments:

geo (Shapely geometry): Any valid shapely geometry

num_results (int): A positive integer for the number of neighbors to return

Returns:

neighbors (List[int]): List of IDs of the closest neighbors in the index
