Hello!
I´m using Snap to work on Sentinel 2 data.
First I imported the data, then I created the Sentinel-2 Level 2A product with athmospheric correction, resampled the data and made a subset of one region. Now I have hopefully correct reflectance values in Snap.
My next step is to export the data to GeoTIFF, but when I open it in another programm (QGIS, R, ENVI), I have wrong values. The initial values prior to the export are between 0 and 1, but my output values are round about between 500 and 6000. I don´t see any pattern like a wrong dimension. First I thought there is a problem with the data type, but I tried all options in the convert datatyp window and had always the same result.
What could be the problem? Snap is updated to the newest version, I work on Windows 10 64 bit.
Thank you!
