I looked everywhere but could not find a solution, usually in the instructions, they say just to open the file or drag and drop the zipped file, but they are generating the same error : “No appropriate product reader found. File (filename) can not be opened.”
It worked, it turned out that the SNAP version I downloaded was the wrong or an old one. After I downloaded the new version it is working, but I have a different problem now, when Applying the DEM (SRTM 3Sec autodownload), to apply it to the image, it is taking for ever (I waited around 24 hours), and then SNAP crushes, when I click on “cancel writing target product”. Any suggestion for a faster solution ?
Many thanks Guys, I actually looked, but it seems I did not look enough, for sure not in the forum, I googled the problem, but did not get the right solution. I will try to see if the suggestion above will work.
Out of curiosity, do you have any idea how much time it takes for the DEM to be applied ? So I don’t wait for ever, before I look for another solution. The solution proposed by ABraun above is also taking time.
