I am fairly new to the Google Earth Engine platform, and I want to create a dataset for my machine learning project using the aforesaid platform. As far I have this code for downloading a single picture:

import ee
# Trigger the authentication flow.
# Initialize the library.

geoJSON = ... # coordinates of rectangle
coords = geoJSON['features'][0]['geometry']['coordinates']
aoi = ee.Geometry.Polygon(coords)

ffa_db = ee.Image(ee.ImageCollection('COPERNICUS/S1_GRD') 
                       .filterDate(ee.Date('2020-08-01'), ee.Date('2020-08-31')) 

url = ffa_db.select('VV').getThumbURL({'min': -20, 'max': 0})

After that, I just download a file with this command: !wget {url} (From Jupyter Notebook) The question is fairly simple, but I had much struggled with it due to the lack of Pythonic ways of doing such things. I searched GEE Community tutorials and Github, but have no luck with them.

How can I download RGB images from Sentinel-2 using Python?

Better to download to a local directory rather than a Google disk.

    what is wrong with the method you exposed? As far as I see you are downloading the image – Rodrigo E. Principe Jan 17 at 20:21
  • @RodrigoE.Principe this code sample is working, but how should I modify it to download images from COPERNICUS/S2 in RGB, because by changing ImageCollection to ImageCollection('COPERNICUS/S2') and selected bands to ffa_db.select('B4', 'B3', 'B2') gives me blank image. I guess I don't understand how bands works, or I don't know what is the problem. I hope I have explained the problem. – Петр Воротинцев Jan 18 at 9:02

You could try to define visualization parameters and then make a new variable where you add the visualization. It would look something like this:

var vis = {
  min: 0,
  max: 3000,

var ffa_db_new = ffa_db.visualize(vis);

And then you export the new variable ffa_db_new instead of the old one.
