在geopandas中融合后删除多边形的内线

import geopandas as gpd
from shapely.geometry import Polygon

polygon1 = Polygon([(0, 0), (0, 1), (1, 1), (1, 0)])
polygon2 = Polygon([(0.5, 0.5), (0.5, 1.5), (1.5, 1.5), (1.5, 0.5)])

gdf = gpd.GeoDataFrame({'geometry': [polygon1, polygon2]})

merged = gdf.unary_union

result = [geom for geom in merged.geoms if not any(geom.within(x) for x in merged.geoms)]
