Exporting true color sentinel image in Google Earth Engine?

Question

I tried to download a sentinel image, but it seems not to work. It downloads a one band image and not 4,3,2 rgb combination as coded.

This is the code I'm using that just downloads 1 band:

var marco = /* color: #d63000 */ee.Geometry.Polygon(
    [[[-70.33198356628418, -16.667604212318242],
      [-70.33138275146484, -16.64129056542051],
      [-70.3795337677002, -16.641043857880046],
      [-70.3795337677002, -16.668426455517558]]]);


var sentinel = ee.Image('COPERNICUS/S2/20180726T144731_20180726T145459_T19KCB').select(['B4', 'B3', 'B2']);

Export.image.toDrive({
 image: sentinel,
 description: 'imageToDriveExample',
 scale: 10,
 region: marco
});

Answer 1

The code works:

The result is a multiband raster with:

• Band1: band4 of S-2
• Band2: band3 of S-2
• Band3: band2 of S-2
