[GIS] add a sentinel 2 image into Google Earth Engine Explorer graphical user interface

google-earth-engine-explorersentinel-2

I am using the graphical user interface of Google Earth Engine (Explorer) to carry out classification of land cover using sentinel 2. My study site is somewhere in Kenya with an id:

S2A_OPER_MSI_L1C_TL_EPA__20150914T075319_20160317T153700_A001190_T37MDU_N02_01_01

However, the format required is:

COPERNICUS/S2/20151128T002653_20151128T102149_T56MNN

and so I attempted to truncate my id to:

COPERNICUS/S2/20150914T074233_20150914T074233_T37MDU

It is still not being accepted by Earth Engine graphical user interface.

A Sentinel-2 product name is composed of the acquisition date in the first place and the ingestion date in second place. When a reprocessing takes place the second date will change.

The image available in EarthEngine you are looking for has the ID COPERNICUS/S2/20150914T074233_20160713T021501_T37MDU

To use it as an image in EarthEngine:

var kenyaSentinel2 = ee.Image("COPERNICUS/S2/20150914T074233_20160713T021501_T37MDU")

Also note, that there's a slight difference in acquisition date (measured at the start of the swath).

To make sure you find the image the easiests way would be to select a polygon for your region and filter the ImageCollection by polygon as well as date, to only show scenes from 2015-09-14.
