ee.Kernel.euclidean

Menghasilkan kernel jarak berdasarkan jarak Euclidean (garis lurus).

Penggunaan	Hasil
ee.Kernel.euclidean(radius, units, normalize, magnitude)	Kernel

Argumen	Jenis	Detail
radius	Float	Radius kernel yang akan dibuat.
units	String, default: "pixels"	Sistem pengukuran untuk kernel ('piksel' atau 'meter'). Jika kernel ditentukan dalam meter, kernel akan diubah ukurannya saat level zoom diubah.
normalize	Boolean, default: false	Menormalisasi nilai kernel agar berjumlah 1.
magnitude	Float, default: 1	Menskalakan setiap nilai dengan jumlah ini.

Contoh

print('A Euclidean distance kernel', ee.Kernel.euclidean({radius: 3}));
