Method Details
-
Performs the generalize operation on the input geometry.
ParametersSpecificationgeometry GeometryThe input geometry to be generalized.
maxDeviation NumberThe maximum allowed deviation from the generalized geometry to the original geometry. If maxDeviation <= 0 the operator returns the input geometry. Unless the
unitoption is set, the default is the spatial reference unit ofgeometry.options ObjectoptionalAdditional options.
SpecificationremoveDegenerateParts BooleanoptionalDefault Value: falsePreserves degenerate parts. The operator will try to output three distinct vertices for closed polyline paths and polygon rings, and it will output two distinct vertices for open polyline paths.
When set to
true, the degenerate parts of the geometry will be removed from the output. This may not be desirable for displaying the geometry.unit LengthUnitoptionalThe length unit of
maxDeviation. An error will be thrown if this is set for Geographic Coordinate Systems.ReturnsExample// Generalize a polyline geometry const generalizedPolyline = generalizeOperator.execute(polyline, 10);
