In Earth Engine, when exporting to drive the raster is shifted

Question

The Problem:

Two identical Landsat scenes were downloaded from two different sources. USGS Earth Explorer and Google Earth Engine. Although both of the scenes are in the exact same coordinate system (EPSG:32638), their pixels do not align correctly. They are shifted 15 meters both horizontally and vertically as shown Below:

I believe that the USGS raster is the correct one, while GEE one has some issues when exporting it.

Data:

To generate the GEE raster please see the following GEE code:

var image = ee.Image('LANDSAT/LC08/C02/T1_L2/LC08_168037_20210918').select('SR_B2')
Map.centerObject(image,8);
Map.addLayer(image , null,'Band 2');

Export.image.toDrive({
    image: image,
    description: 'testImage',
    fileNamePrefix: 'testImage',
    scale: 30,
    // region: aoi,
    maxPixels: 1e10,
    crs:'EPSG:32638',
    folder: 'Image Production'
    })

• USGS raster can be downloaded here
• GEE raster can be downloaded here

Non-Working solutions:

• I've tried the solution in Align images with self-defined CRS in Google Earth Engine and this post, but none of them worked.
• I've also tried to use a custom projection (wkt) but didn't succeed.

My request:

• To be able to export Landsat8 rasters perfectly aligned with their corresponding ones in USGS Earth explorer.
• To be able to export Sentinel2 rasters perfectly aligned with their corresponding ones in Scihub.

Answer 1

If you additionally pass in the crs transform to the export call and remove the scale parameter everything should line up perfectly. You can access the transform like this: image.projection().getInfo().transform.

Then you can export like this:

Export.image.toDrive({
    image: image,
    description: 'testImage',
    fileNamePrefix: 'testImage',
    // region: aoi,
    maxPixels: 1e10,
    crs:'EPSG:32638',
    crsTransform: image.projection().getInfo().transform,
    folder: 'Image Production'
})
