ee.data.makeDownloadUrl
Create a download URL from a docid and token.
Returns the download URL.
Usage | Returns | ee.data.makeDownloadUrl(id) | String |
Argument | Type | Details | id | DownloadId | A download id and token. |
Examples
Code Editor (JavaScript)
// A Sentinel-2 surface reflectance image.
var img = ee.Image('COPERNICUS/S2_SR/20210109T185751_20210109T185931_T10SEG');
// A small region within the image.
var region = ee.Geometry.BBox(-122.0859, 37.0436, -122.0626, 37.0586);
var downloadId = ee.data.getDownloadId({
image: img,
name: 'single_band',
bands: ['B3', 'B8', 'B11'],
region: region
});
print('Single-band GeoTIFF files wrapped in a zip file',
ee.data.makeDownloadUrl(downloadId));
