Geodataframe set geometry. Aggregating and exploding# GeoDataFrame GeoPandas leverages Pandas together with several core open source geospatial packages and practices to provide a uniquely simple and convenient framework for handling geospatial feature data, operating on both geometries and attributes jointly, and as with Pandas, largely eliminating the need to iterate over features (rows) You can get a construct with actual length using: With a list of GeoJSON-like Python geo interface geometries, simply use shapely Bu yüzden onu bir Geodataframe olarak dönüştürüyorum Exception: Spatial column not defined, please use `set_geometry` Even though I have run the method 2 lines above GeoDataFrame 也可能包含其他带有几何(形状)对象的列,但一次只能有一列是活动几何体。要更改哪个列是活动几何图形列,请使用 set\u geometry 方法 Geopandas ile bir komut dosyası yazıyorum
