Questions about the conversion from pixel value to reflectance value in PSScence4Band product
Hi,
What does the pixel value mean in the `analytic` and 'analytic_sr' file? DNs or TOA Radiance?
If I want to convert the pixel value in `analytic_sr` file to the surface reflectance value which should be in 0-1, where I can find the scale factor or reflectance coefficient to do that?
Thanks

Hi Chenyong,
The SR product is provided as a 16-bit GeoTIFF image with reflectance values scaled by 10,000.
