我有一个多多边形Shapfile，我想旋转.我可以做旋转，但问题是旋转器改变了内部顶点.这就创造了我不想要的多边形重叠.
这就是我try 过的.
import geopandas as gpd
input_poly_path = "poly3.shp"
gdf = gpd.read_file(input_poly_path)
explode = gdf.explode(ignore_index=True)
ex = explode.rotate(-90, origin="centroid")
g = gpd.GeoDataFrame(columns=['geometry'], geometry='geometry')
g["geometry"] = ex

IIUC，你需要通过unary_union的centroid作为旋转的origin:
out = gpd.GeoDataFrame(
geometry=gdf.rotate(
angle=-90, origin=list(gdf.unary_union.centroid.coords)[0]
)
)
102: There is no need to 100 the geometry, because you do not have 101.
使用的输入(gdf):
import geopandas as gpd
# download from Google Drive
input_poly_path = (
"C:/Users/Timeless/Downloads/"
"share-20240330T125957Z-001.zip!share"
)
gdf = gpd.read_file(input_poly_path, engine="pyogrio")
