S1 Multitemporal Speckle filter

Hello everybody,

I am trying to apply a multitemporal speckle filter on 31 layer stacked SAR calibrated GRD image

The SNAP is not accomplishing the job as it says that: “band1 requires a unit”

The image is an img float 32

Does anyone have an idea about this error type

From the band name “band1” it seems you are using the GeoTiffs directly which doesn’t include any metadata.
Try opening the products with the manifest.safe file, calibration, coregister and then apply the filter.
