ready raster = how to use it?

[asiya-z]

Is it possible to use multi-channel raster S 2previously prepared in GEE for this classification tool ? I couldn't find a way to do this. Thanks a lot !

Hello @asiya-z , yes it is possible to use any raster that you can open in QGIS. You can select it in the Band set tab.
In case it is a multiband raster I suggest to use this tool to split the bands and then create a Band set https://semiautomaticclassificationmanual.readthedocs.io/en/latest/split_bands_tab.html

Thanks you, I have already done a raster split using GDAL. Please advise if it is possible to use WGS84 for raster and signature gpkg ? I was unable to export an image to UTM from GEE. When attempting to reproject in QGIS, the picture becomes distorted and the file size increases several times over. I usually use GEE myself and escape these issues but I need to prepare examples and a workflow for students working in QGIS.

You are welcome @asiya-z . Yes it is possible to use WGS84, but it is preferable to use projected coordinates.
You can export to UTM in GEE with the crs option, see https://developers.google.com/earth-engine/guides/exporting_images?hl=it#to_drive

Thank you very much, I probably didn't write the export function quite correctly last time(
