Webb6 juli 2024 · The Shapely polygon’s area attribute returns a value of 6400, which corresponds to 80 times 80. And is, therefore, correct. area = polygon.area Area of Polygons (Image by author from Kaggle) However, not all polygons are closed shapes. Sometimes, polygons can have ‘holes’, which are called interiors in the Shapely package. Webb10 dec. 2024 · Maybe try keeping all the original polygons in tact and when you need to know the what A looks likes when B, C, and D are subtracted from it, take the union of B, C, and D first and then diff A. If small 'cracks' appear where B was adjacent to C, maybe take a small buffer of the union before diffing. WebbUse Shapely's shapely.ops.transform function to transform the polygon to projected equal area coordinates and then take the area. green goblin death comic
