-
Interface Summary Interface Description SpatialPartition.EquivalenceRelation An interface for a function to compute an equivalence relation.UnionStrategy A strategy class that adapts UnaryUnion to different kinds of overlay algorithms. -
Class Summary Class Description CascadedPolygonUnion Provides an efficient method of unioning a collection ofPolygonal
geometries.DisjointSets A data structure that represents a partition of a set into disjoint subsets, and allows merging subsets.OverlapUnion Deprecated. due to impairing performancePartitionedUnion Unions a set of polygonal geometries by partitioning them into connected sets of polygons.PointGeometryUnion SparsePolygonUnion Unions a set of polygonal geometries by partitioning them into connected sets of polygons.SpatialPartition Computes a partition of a set of geometries into disjoint subsets, based on a provided equivalenceSpatialPartition.EquivalenceRelation
.UnaryUnionOp UnionInteracting Experimental code to union MultiPolygons with processing limited to the elements which actually interact.
