Python: temukan metode untuk menghitung "inner centroid" (juga dikenal sebagai labelPoint di arcmap) dari poligon

saya mencari metode untuk menghitung koordinat X, Y dari titik dalam (juga dikenal sebagai labelPoint di arcmap) dari poligon (tidak beraturan). Saya mencoba mencari solusi tanpa menggunakan modul ArcGIS

perbedaan antara "centroid" dan labelPoint adalah bahwa centroid mungkin berada di luar poligon.

Saya menggunakan modul rupawan

dari impor impor Shapely.geometry

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

menggunakan data berikut (titik poligon saya)

terima kasih sebelumnya atas bantuan dan sarannya

Saya pikir poin representatif adalah apa yang Anda cari

http://toblerity.github.com/shapely/manual.html#object.representative_point

Pada dasarnya, Anda hanya akan menggunakan ref_polygon.representative_point (). Wkt daripada metode centroid.
