增加几何熊猫中多边形几何的半径

问题描述

我在几何形状下的几何熊猫df中有一堆呈饼状的多边形，如下图所示，我正在考虑将多边形的半径从x增加到y。

这可以用大熊猫做吗？我不确定从哪里开始。任何帮助或提示将不胜感激。谢谢。预先为手绘图致歉。

df_poly = pd.DataFrame(data,columns = ['poly_ID','lon','lat']) 

lat = df_poly.lat.tolist()
lon = df_poly.lon.tolist()

polygon_geom = polygon(zip(lon,lat))
crs = {'init': 'epsg:4326'}
polygon = gp.GeoDataFrame(index=[0],crs=crs,geometry=[polygon_geom])       


import folium
m = folium.Map([50.854457,4.377184],zoom_start=5,tiles='cartodbpositron')
folium.GeoJson(polygon).add_to(m)
folium.LatLngPopup().add_to(m)
m

解决方法

看看shapely.affinity.scale方法。使用此功能，您可以根据需要在x和y方向上缩放几何！ Shapely affinity scale
