[GIS] Downloading Sentinel-2 L2A with Google Cloud BigQuery

google-cloudsentinel-2

I'm trying to download Sentinel-2 data in Level 2A from Google Cloud Storage.

Level 1C works perfect with the following (already discussed) method:
Download script for L1C

Now I want to do the same with L2A data but I do not know how to change the existing function query_sentinel.

Could anybody help me?

Sentinel-2 L2A imagery cannot be downloaded from Google. Only L1C data is available there. You can download L2A data from AWS (chargeable) or for free using the Sentinelsat API.

Two issues with your script:

1) A single image works best when you use ee.Image instead of ee.ImageCollection.

2) You switched up the granule name. The first part is the sensing time and the second the ingestion time. An acquisition taken in 2016 cannot be ingested in 2015. It should be 20150828T110656_20160412T015159_T30SVG not the other way round.

As a complete script (on EarthEngine):

// not in Collection - switched sensing and acquisition time
// var s2 = ee.Image('COPERNICUS/S2/20160412T015159_20150828T110656_T30SVG');
// in Collection - correct granule
var s2 = ee.Image('COPERNICUS/S2/20150828T110656_20160412T015159_T30SVG');
Map.addLayer(s2, {bands: ['B8', 'B4', 'B3'], max: 4000}, 'S2')
Map.centerObject(s2, 8);
