Perform a topological union operation on two geometries. | unionOperator | ||
Perform a topological union operation on a geometry set. | unionOperator |
Method Details
-
execute
Methodexecute(geometry1, geometry2){GeometryUnion |null |undefined} -
Perform a topological union operation on two geometries.
Parametersgeometry1 GeometryUnionThe first geometry to union with.
geometry2 GeometryUnionThe second geometry to union with.
ReturnsType Description GeometryUnion | null | undefined Returns the union of the two geometries as a geometry or null. Example// Return the union of two polygons const union = unionOperator.execute(polygon1, polygon2);
-
executeMany
MethodexecuteMany(geometries){GeometryUnion |null |undefined} -
Perform a topological union operation on a geometry set.
Parametergeometries GeometryUnion[]The array of geometries to union. All the geometries must have the same spatial reference.
ReturnsType Description GeometryUnion | null | undefined Returns the union of geometriesas a geometry or null.
