程式碼編輯器 (JavaScript)

// A dictionary (e.g. results of ee.Image.reduceRegion of an S2 image).
var dict1 = ee.Dictionary({
  B1: 182,
  B2: 219,
  B3: 443
});

// A second dictionary.
var dict2 = ee.Dictionary({
  Region: 'The Forest of Nisene Marks State Park',
  Image: 'Sentinel-2 surface reflectance (scaled by 1e4)',
  B1: -9999  // Note that the B1 key is present in both dictionaries.
});

print('Combined dictionaries (overwrite false)',
      dict1.combine(dict2, false));

print('Combined dictionaries (overwrite true)',
      dict1.combine(dict2, true));
