WebTiny sliver polygons or gaps between polygons often result from creating polygons without using snapping or from editing shared boundaries without a topology. A sliver polygon is defined by its thinness ratio and maximum area. If a polygon is below a specified thinness ratio and area, it is considered a sliver. WebAs can be seen, the geometries are referenced by two segments ('arcs': [[0], [1]]), where each segment is a single linestring (see: arcs). When doing the same with topology=True, there are three arcs. Where one arc is referenced two times, namely arc 2 (arc … Web11 rows · Topological relationships.
