示例
代码编辑器 (JavaScript)
// A Sentinel-2 surface reflectance image.
var img = ee.Image('COPERNICUS/S2_SR/20210109T185751_20210109T185931_T10SEG')
.select(['B11', 'B8', 'B3']);
print('Original selected S2 image band names', img.bandNames());
print('Rename bands using a list (JavaScript array or ee.List)',
img.rename(['SWIR1', 'NIR', 'GREEN']).bandNames());
print('Rename bands using a series of string arguments',
img.rename('swir1', 'nir', 'green').bandNames());
