# PolyPartition
## Description
Subdivides MultiPolygon geometries in a list until all polygons are less than a given area
`PolyPartition.get_split(<List of MultiPolygon geometries>, <area bound in mi^2>)`
To get a result as a GeoJSON feature collection:
`PolyPartition.get_split_geojson(<List of MultiPolygon geometries>, <area bound in mi^2>)`
