Google Earth Engine – How to Get a List of Bands

bandgoogle-earth-enginelist

I want to Automate Band selection for all bands. Therefore a List of the Bands is needed. This didn´t work:

ee.List(image.get('bands'))

Best Answer

You can get a list of all the bands in an image by using:

var band_names = image.bandNames()

You could use the following to select the first 11 bands:

// select the first 11 bands
var lsat = lsat.select(ee.List.sequence(0,10)); // or e.g. select([0,3,7]) for some other bands

You could also cast the bands to the same data type:

// cast image to same data type
var toFloat = lsat.toFloat();

Here is another approach:

// Make a (toy) 3 bands image
var image  = ee.Image([1,2,3]).rename(['one', 'two', 'three'])
Map.addLayer(image, null, '3 bands image')

// Sum all bands
var sum_bands = image.reduce('sum')
Map.addLayer(sum_bands, null, 'sum')

// You can compute any reduction
var mean_bands = image.reduce('mean')
Map.addLayer(mean_bands, null, 'mean')
