Pengumuman: Semua project nonkomersial yang terdaftar untuk menggunakan Earth Engine sebelum
15 April 2025 harus
memverifikasi kelayakan nonkomersial untuk mempertahankan akses Earth Engine.
ee.Dictionary.aside
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Memanggil fungsi yang meneruskan objek ini sebagai argumen pertama, dan menampilkan dirinya sendiri. Nyaman, misalnya saat men-debug:
var c = ee.ImageCollection('foo').aside(print)
.filterDate('2001-01-01', '2002-01-01').aside(print, 'In 2001')
.filterBounds(geom).aside(print, 'In region')
.aside(Map.addLayer, {min: 0, max: 142}, 'Filtered')
.select('a', 'b');
Menampilkan objek yang sama, untuk pembuatan rantai.
| Penggunaan | Hasil |
|---|
Dictionary.aside(func, var_args) | ComputedObject |
| Argumen | Jenis | Detail |
|---|
ini: computedobject | ComputedObject | Instance ComputedObject. |
func | Fungsi | Fungsi yang akan dipanggil. |
var_args | VarArgs<Object> | Argumen tambahan yang akan diteruskan ke fungsi. |
Contoh
Code Editor (JavaScript)
// A dictionary (e.g. results of ee.Image.reduceRegion of an S2 image).
var dict = {
B1: 182,
B2: 219,
B3: 443
};
// Print a message when constructing the ee.Dictionary.
var eeDict = ee.Dictionary(dict).aside(print, 'ee.Dictionary from an object');
