ee.Kernel.octagon

Menghasilkan kernel boolean berbentuk segi delapan.

Penggunaan	Hasil
ee.Kernel.octagon(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: benar (true)	Menormalisasi nilai kernel agar berjumlah 1.
magnitude	Float, default: 1	Menskalakan setiap nilai dengan jumlah ini.

Contoh

Code Editor (JavaScript)

print('An octagon kernel', ee.Kernel.octagon({radius: 3}));
