Shapely buffer 0

Webbshapely是一个平面几何库， z, 几何分析中忽略了平面上或平面下的高度。 这里的用户有一个潜在的陷阱：只在 z 它们之间没有区别，它们的应用可能导致极其无效的几何对象。 例如， LineString ( [ (0, 0, 0), (0, 0, 1)]) 不返回单位长度的垂直线，而是返回长度为零的平面中的无效线。 同样地， Polygon ( [ (0, 0, 0), (0, 0, 1), (1, 1, 1)]) 不受闭合环的约束，因此无效 … Webb最后buffer还有个隐藏的功能，在shapely的合法性规则里有限制一些几何图形，比如Polygon的边不能交叉，否则就是不合法的，使用is_valid()可以判断对像是否合法，如果一个非法的对象通过buffer(0)的方法缓冲0距离可以直接转换成合法的对象。 2. boundary.

WebbShapely geometries are, by design, agnostic (unaware) of the reference system used to represent them. Distances and surface area calculated using the built-in shapely methods will always: a) assume a flat, Cartesian, Euclidean space, and b) return the calculated value in the unit of the coordinates (e.g., meters, or degrees). WebbShapely is a BSD-licensed Python package for manipulation and analysis of planar geometric objects. It is based on the widely deployed GEOS (the engine of PostGIS) and JTS (from which GEOS is ported) libraries. 用shapely生成缓冲区时，主要使用object.buffer(distance,…)语法。 在开始示例之前，先引入点线面类型。 how bad are the ads on hulu
