WebbA polygon is a two-dimensional feature and has a non-zero area. It may have one or more negative-space “holes” which are also bounded by linear rings. If any rings cross each other, the feature is invalid and operations on it may fail. Webbfrom shapely.geometry import Point, Polygon # Create three points that will define the polygon outlines point1 = Point(0, 0) point2 = Point(3, 1) point3 = Point(0, 3) polygon2 = Polygon( [ [p.x, p.y] for p in [point1, point2, point3]]) However, it might be that we need a more complex polygon shape with interior holes.

WebbCreating a Shapely Polygon Before we begin plotting Polygons, we need to actually create one first. This can be done by importing the Polygon Class from the shapely module. Make sure you actually have shapely installed before running this command though. 1 2 3 from shapely.geometry import Polygon WebbEARTH_POLYGON = MultiPoint(POINTS).convex_hull def _get_start_coord (): """ Get a top-left point to start our downward-rightward crop that is inside the Earth polygon Returns: … earn money through typing without investment

If small 'cracks' appear where B was adjacent to C, maybe take a small buffer of the union before diffing.
