WebThe Polynomial Approximation with Exponential Kernel (PAEK) method ( PAEK in Python) smooths polygons based on a smoothing tolerance. Each smoothed polygon may have more vertices than its source polygon. The Smoothing Tolerance parameter controls the length of a moving path used in calculating the new vertices. 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.

WebClean builds polygon and arc-node topology by identifying areas enclosed by arcs and creates the list of arcs that define each polygon boundary. Clean also numbers nodes and establishes the from-node and to-node for each arc as well as the internal polygon numbers to the left and right of each arc.
