The purple is the original polygon to be smoothed and I would like to smooth the polygons as the red line using Python.
I tried simplify but looks like I need a buffer and simplify the buffer. But I want to simplify the polygon directly. I am open to any other methods using Python.
import geopandas as gpd
d = gpd.read_file('poly.shp')
x = d.buffer(0.0001)
tolerance = 0.00005
simplified = x.simplify(tolerance, preserve_topology=True)
simplified.to_file('simplified.shp')

The simplify method is a Ramer-Douglas-Peucker vertex removal algorithm. If you want a Bend-Simplify or something more exotic you might have to code it yourself.
