I'm trying to download about 200 images using Sentinel-2 but when I open them in ArcMap, RGB color is not showing and its showing as blank image. This is happening with all of my images. The code I used for downloading images is: https://code.earthengine.google.com/8e5a75c94fd5a96dbec7c4916dcbf38f

But the images are like: enter image description here

Since you didn't convert DN to Reflectance, use visualization parameters with scale factor:

var visualization = {
  min: 0,
  max: 3000,
  bands: ['B4', 'B3', 'B2'],
};

  • I don't want to visualize it in gee. I'm asking after the image is downloaded, its showing blank as in attached image. I have also changed symbology in arcmap but no rgb image

  • Ah, compute statistics or use custom stretch with min: 0, max: 3000.

  • Computed statistics but nothing improved.

  • Set custom stretch then, the rasters are ok, the problem symbology setup

    I noticed that you commented the line that maps the maskS2clouds function to the image collection. If you left that mapping out, then your values are integers, as @aldo_tapia commented. If so, then you need to set your visualization parameters in ArcGIS correctly. If you did use the masks2clouds function, then you have float values and you should change that in the parameters to the batch.Download.ImageCollection.toDrive function (currently using "int16").
