Pengumuman: Semua project nonkomersial yang terdaftar untuk menggunakan Earth Engine sebelum
15 April 2025 harus
memverifikasi kelayakan nonkomersial untuk mempertahankan akses Earth Engine.
ee.Geometry.MultiLineString.getInfo
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Mengambil nilai objek ini dari server.
Jika tidak ada fungsi callback yang diberikan, permintaan akan dibuat secara serentak. Jika callback disediakan, permintaan dibuat secara asinkron.
Mode asinkron lebih disukai karena mode sinkron menghentikan semua kode lainnya (misalnya, UI Editor Kode EE) saat menunggu server. Untuk membuat permintaan asinkron, evaluate() lebih disarankan daripada getInfo().
Menampilkan nilai terkomputasi dari objek ini.

callback | Fungsi, opsional | Callback opsional. Jika tidak diberikan, panggilan dilakukan secara sinkron. |
Contoh
Code Editor (JavaScript)
// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
[[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
[[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);
// Apply the getInfo method to the MultiLineString object.
var multiLineStringGetInfo = multiLineString.getInfo();
// Print the result to the console.
print('multiLineString.getInfo(...) =', multiLineStringGetInfo);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiLineString,
{'color': 'black'},
'Geometry [black]: multiLineString');
