I’m usint SNAP software but I have met some problems relative to the Supervised Classification.
In particular, I’m working with Sentinel 2 data following these steps:
1- Resampling (output resolution 10)
3- Reprojection (WSG84)
Then, I create a new vector data container using vector polygons function but, when I open them, the style_css column results blank.
Moreover when I run the classification (MLC and/or MDC) the whole output image (Labeled classed) results black and in in frequency column of the Colour Manipolation panel I find a question mark.
Can anyone help me?
