I'm exporting a map to my drive using the GEE python API, I'm looking for a way to retreive all the created files automatically to a local folder.

my current code create a image on my drive :

def download_to_disk(country_code, year):
    """download the tile to the GEE disk"""
    file_name = 'alerts_' + country_code + '_' + year
    task_config = {
        'scale': 30,
        'maxPixels': 1e10
    task = ee.batch.Export.image.toDrive(**task_config)

Is there a way to retrieve the files created by this very task automatically using only the Python API ?

  • where does the variable service come from? I think your question is related to GDrive Python API and not GEE Jun 28, 2020 at 14:25
  • It was just a bad copy-paste from the documentation. I realized my question wasn't super clear so I edited it. I pretty sure it's basic usage I just didn't find the appropriate documentation or example. Jun 29, 2020 at 4:53

So after crawling a bit on the internet I found a workaround :

It's impossible to retreive a file from Gdrive with a task name or a filename are they are all identify with their unique ID.

Solution is to create a function that crawls into your files in your drive and select thoses corresponding to your task. in my case it look like :

import ee

class gdrive(object):

    def __init__(self):
        self.initialize = ee.Initialize()
        self.credentials = ee.Credentials()
        self.service = discovery.build(serviceName='drive', version='v3', cache_discovery=False, credentials=self.credentials)

    def get_files(self, file_name):
        """ look for the file_name patern in my Gdrive files and retreive a list of Ids"""
        items = self.get_items()
        files = []
        for item in items:
            if (file_name in item['name']):
                files.append({'id':item['id'], 'name': item['name']})
        return files

then in the same gdrive object I created a function that retreive all my selected files from my drive to my local path.

from googleapiclient.http import MediaIoBaseDownload

class gdrive(object):
    # [...] som code

    def download_files(self, files, local_path):
        service = self.service
        for fId in files:
            request = service.files().get_media(fileId=fId['id'])
            fh = io.BytesIO()
            downloader = MediaIoBaseDownload(fh, request)
            done = False
            while done is False:
                status, done = downloader.next_chunk()
                #print('Download %d%%.' % int(status.progress() * 100))
            fo = open(local_path+fId['name'], 'wb')

hope that it will help someone
