파이썬 : 다각형의 "내부 중심"(아크 맵에서 labelPoint라고도 함)을 계산하는 방법을 찾으십시오.

(불규칙한) 다각형의 내부 점 (arcmap에서 labelPoint라고도 함)의 X, Y 좌표를 계산하는 방법을 찾고 있습니다. ArcGIS 모듈을 사용하지 않고 솔루션을 찾으려고합니다.

"중심점"과 labelPoint의 차이점은 중심이 다각형 외부에있을 수 있다는 것입니다.

내가 사용하고 매끈한 모듈을

shapely.geometry에서 다각형 가져 오기

ref_polygon = Polygon(points)
# get the x and y coordinate of the centroid
ref_polygon.centroid.wkt
'POINT (558768.9293489187300000 6361851.0362532493000000)'

다음 데이터를 사용합니다 (내 다각형의 꼭짓점)

도움과 제안에 미리 감사드립니다
