I had to use convex_hull: poly = MultiPoint(list_points).convex_hull What is not exaclty what I'm looking for. Thanks for the patience and the good work!Contributor sgillies commented Aug 30, 2012 Here's thing: polygon rings (instances of LinearRing) aren't defined by Points, they ...
要将单个Point几何与多个其他Point几何进行比较,可以使用.unary_union与生成的MultiPoint几何进行比较。
