ee.Kernel.euclidean

Generates a distance kernel based on Euclidean (straight-line) distance.

Usage	Returns
ee.Kernel.euclidean(radius, units, normalize, magnitude)	Kernel

Argument	Type	Details
radius	Float	The radius of the kernel to generate.
units	String, 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.
normalize	Boolean, default: false	Normalize the kernel values to sum to 1.
magnitude	Float, default: 1	Scale each value by this amount.

Examples
