SimplifyProcessor

Vector processor that simplifies a layer

The polygons are simplified using a topology-preserving Visvalingam-Whyatt algorithm.

Implements the VectorProcessor protocol.

PARAMETER	DESCRIPTION
layer_name	Layer name TYPE: str
threshold	Threshold (the minimum area of the triangle defined by three consecutive vertices to retain) in square meters TYPE: float
new_layer_name	New layer name TYPE: str | None DEFAULT: None

from_config classmethod

Creates a simplify processor from the configuration.

PARAMETER	DESCRIPTION
config	Configuration TYPE: SimplifyProcessorConfig

RETURNS	DESCRIPTION
SimplifyProcessor	Simplify processor

__call__

Simplifies the layer.

PARAMETER	DESCRIPTION
vector	Vector TYPE: Vector

RETURNS	DESCRIPTION
vector	Vector TYPE: Vector

SimplifyProcessorConfig

Bases: pydantic.BaseModel

Configuration for the from_config class method of SimplifyProcessor

Create the configuration from a config file

• Use null instead of None

Example

You can create the configuration from a config file.

config.yaml

package: 'aviary'
name: 'SimplifyProcessor'
config:
  layer_name: 'my_layer'
  threshold: 1.
  new_layer_name: 'my_new_layer'

ATTRIBUTE	DESCRIPTION
layer_name	Layer name TYPE: str
threshold	Threshold (the minimum area of the triangle defined by three consecutive vertices to retain) in square meters TYPE: float
new_layer_name	New layer name - defaults to None TYPE: str | None
