Method Details
-
executeMany
MethodexecuteMany(geometries, options){GeometryUnion[]} -
Performs the multipart to single part operation on the input geometries. Single part geometries will not be affected (i.e. they just get passed along) with the exception of multipoints, which always become points. By default, polygons will be simplified before producing single parts.
Parametersgeometries GeometryUnion[]The input geometries to be converted to single part geometries. All the geometries must have the same spatial reference.
options ObjectoptionalAdditional options.
SpecificationsimplifyPolygons BooleanoptionalDefault Value: trueWhen this parameter is set to false, the input polygons will not be simplified before converting them to single part geometries. Make sure the input polygons are topologically simple. Otherwise, the operation may assume incorrect ring orientation or order of rings.
ReturnsType Description GeometryUnion[] Returns the single part geometries. For non-simple polygons, the output of the method is not guaranteed to be correct if the simplifyPolgonsoption is set tofalse. In that case, the method may either throw an error, or produce some output which is not guaranteed to be correct.Example// Convert multipart geometries to single part geometries const singlePartGeometries = multiPartToSinglePartOperator.executeMany(multiPartGeometries);
