Get lat/long values for 2D matrix purposes

Good Morning,

I’d like to know if it’s possible to convert the two images below into 2D matrix (which will be written in a txt file for example).

In this way, I could easily convert X/Y coordinates into lat/long coordinates.

Thank you.

Please have a look in the menu at File / Export / CSV. This can export a whole product.
You can also draw a polygon and export only the masked pixels. Chose from the context menu Export Mask Pixel or from the menu Raster / Export / Mask Pixels
