I had raw RSAT-2 fine beam image. I calibrated and converted to dB in GeofTiff format in SNAP. Later on, I was trying to perform terrain correction for that image using SNAP desktop. It looks like SNAP cannot handle this file size. Any idea how to avoid this error?

I can’t see your error message image but, I’m guessing after terrain correction the image is over the 32bit limit of GeoTIFF. You could write to BigTiff instead.

In general though, you’re better off working in BEAM-DIMAP until the last operation you do and then export to some other format like BigTiff.

Thanks for the promot response. It seems BigTiff is working. :relaxed:
