(不規則な)ポリゴンの内側のポイント(アークマップではlabelPointとも呼ばれます)のX、Y座標を計算する方法を探しています。ArcGISモジュールを使用せずに解決策を見つけようとしています。
「重心」とlabelPointの違いは、重心が多角形の外側にある可能性があることです。
shapely.geometryインポートポリゴンから
ref_polygon = Polygon(points)
# get the x and y coordinate of the centroid
ref_polygon.centroid.wkt
'POINT (558768.9293489187300000 6361851.0362532493000000)'
次のデータ(ポリゴンの頂点)を使用します
