Generates a distance kernel based on Chebyshev distance (greatest distance along any dimension).

UsageReturns
ee.Kernel.chebyshev(radius, units, normalize, magnitude)Kernel
ArgumentTypeDetails
radiusFloatThe radius of the kernel to generate.
unitsString, default: "pixels"The system of measurement for the kernel ('pixels' or 'meters'). If the kernel is specified in meters, it will resize when the zoom-level is changed.
normalizeBoolean, default: falseNormalize the kernel values to sum to 1.
magnitudeFloat, default: 1Scale each value by this amount.
