The new overlay engine (aka &#8220;<a href="https://lin-ear-th-inking.blogspot.com/2020/10/overlayng-lands-in-jts-master.html">OverlayNG</a>&#8221;) provides <a href="https://lin-ear-th-inking.blogspot.com/2020/06/jts-overlayng-tolerant-topology.html">more robust</a> handling of difficult input geometries, using a set of <a href="https://lin-ear-th-inking.blogspot.com/2020/06/jts-overlayng-noding-strategies.html">new noding strategies</a> to process geometry. For the end user, this should mean no more &#8220;topology exceptions&#8221; when using the union, difference, intersection or symmetric difference functions. PostGIS also exposes the new fixed precision overlay capability via an additional grid-size parameter on <a href="http://postgis.net/docs/manual-dev/ST_Intersection.html">ST_Intersection</a> and the other overlay functions.</p> Continue Reading by clicking title hyperlink ..
