SlopeProcessor

Bases: IDMixin

Tiles processor that computes the slope from a channel

Experimental

SlopeProcessor is experimental since 1.3.0 and may change without notice.

Notes

• Requires a raster channel

Implements the TilesProcessor protocol.

SlopeProcessorConfig

Bases: pydantic.BaseModel

Configuration for the from_config class method of SlopeProcessor

Create the configuration from a config file

• Use 'degrees' or 'percent' instead of SlopeUnit.DEGREES or SlopeUnit.PERCENT
• Use null instead of None

Usage

You can create the configuration from a config file.

config.yaml

package: 'aviary'
name: 'SlopeProcessor'
config:
  channel_name: 'dem'
  unit: 'degrees'
  new_channel_name: 'slope'
  max_num_threads: null

ATTRIBUTE	DESCRIPTION
channel_name	Channel name - defaults to 'dem' TYPE: ChannelName | str
unit	Unit of the slope (DEGREES or PERCENT) - defaults to DEGREES TYPE: SlopeUnit
new_channel_name	New channel name - defaults to 'slope' TYPE: ChannelName | str
max_num_threads	Maximum number of threads - defaults to None TYPE: int | None
