Menambahkan objek EE tertentu ke peta sebagai lapisan.

Menampilkan lapisan peta baru.

Penggunaan	Hasil
Map.addLayer(eeObject, visParams, name, shown, opacity)	ui.Map.Layer

Argumen	Jenis	Detail
eeObject	Collection|Feature|Image|RawMapId	Objek yang akan ditambahkan ke peta.
visParams	FeatureVisualizationParameters|ImageVisualizationParameters, opsional	Parameter visualisasi. Untuk Gambar dan ImageCollection, lihat ee.data.getMapId untuk parameter yang valid. Untuk Fitur dan FeatureCollection, satu-satunya kunci yang didukung adalah "color", sebagai string warna CSS 3.0 atau string hex dalam format "RRGGBB". Diabaikan jika eeObject adalah ID peta.
name	String, opsional	Nama lapisan. Defaultnya adalah "Layer N".
shown	Boolean, opsional	Tanda yang menunjukkan apakah lapisan harus aktif secara default.
opacity	Nomor, opsional	Opasitas lapisan ditampilkan sebagai angka antara 0 dan 1. Default-nya adalah 1.

Contoh

Code Editor (JavaScript)

// A Sentinel-2 surface reflectance image.
var image = ee.Image('COPERNICUS/S2_SR/20210109T185751_20210109T185931_T10SEG');
Map.setCenter(-121.87, 37.44, 9);

// Set multi-band RGB image visualization parameters. If the "bands" parameter
// is not defined, the first three bands are used.
var rgbVis = {
  bands: ['B11', 'B8', 'B3'],
  min: 0,
  max: 3000
};
Map.addLayer(image, rgbVis, 'Multi-band RGB image');

// Set band-specific "min" and "max" properties.
var rgbVisBandSpec = {
  bands: ['B11', 'B8', 'B3'],
  min: [0, 75, 150],
  max: [3500, 3000, 2500]
};
Map.addLayer(image, rgbVisBandSpec, 'Band-specific min/max');

// If you don't specify "min" and "max" properties, they will be determined
// from the data type range, often resulting in an ineffective color stretch.
Map.addLayer(image.select('B8'), null, 'Default visParams');

// If an image layer has already been styled, set "visParams" as null.
var imageRgb = image.visualize(rgbVis);
Map.addLayer(imageRgb, null, 'Pre-styled image');

// Use the "palette" parameter with single-band image inputs to define the
// linear color gradient to stretch between the "min" and "max" values.
var singleBandVis = {
  min: 0,
  max: 3000,
  palette: ['blue', 'yellow', 'green']
};
Map.addLayer(image.select('B8'), singleBandVis, 'Single-band palette');

// Images within ImageCollections are automatically mosaicked according to mask
// status and image order. The last image in the collection takes priority,
// invalid pixels are filled by valid pixels in preceding images.
var imageCol = ee.ImageCollection('COPERNICUS/S2_SR')
                   .filterDate('2021-03-01', '2021-04-01');
Map.addLayer(imageCol, rgbVis, 'ImageCollection mosaic');

// FeatureCollection, Feature, and Geometry objects can be styled using the
// "color" parameter.
var featureCol = ee.FeatureCollection('WCMC/WDPA/current/polygons');
Map.addLayer(featureCol, {color: 'purple'}, 'FeatureCollection');
