Acquire JPEG images from GEOTIFF

[tayalkshitij]

I am using the following command to get RGB images:

gdal_translate -b 4 -b 3 -b 2 -of JPEG -scale inputimage.tif outputfile.jpeg

RGB images obtained from the above command is not same as supplied by EuroSAT.
Can you let me know what is the procedure that you have used to covert EuroSAT GEOTIFF to JPEG ?

To get RGB image with the same scale as the EuroSAT rgb data from
downloaded Sentinel images you have to clip your original Sentinel-2
data. The maintainer of the EuroSAT data told me, that they clipped the
original data from range 0 to 2750 to the range 1 to 255, leaving 0 for
nodata values:

gdal_translate --config GDAL_PAM_ENABLED NO -of JPEG -co QUALITY=100 
-ot Byte -a_nodata 0 -scale 0 2750 1 255 -b 4 -b 3 -b 2 -of JPEG 
inputimage.tif  outputfile.jpeg ```

 (additional option '-co 
PHOTOMETRIC=RGB' if using GeoTIFF as output)
