Abstract class for geodata postprocessors
Geodata postprocessors are callables that postprocess geodata. The geodata postprocessor is used by the pipeline to postprocess the resulting geodata, which is the vectorized output of the model's inference.
Currently implemented geodata postprocessors
- ClipPostprocessor: Clips the polygons based on the mask extent
- CompositePostprocessor: Composes multiple geodata postprocessors
- FieldNamePostprocessor: Renames the fields
- FillPostprocessor: Fills holes in the polygons
- SievePostprocessor: Sieves the polygons
- SimplifyPostprocessor: Simplifies the polygons by applying the Douglas-Peucker algorithm
- ValuePostprocessor: Maps the values of a field
