Dear all,

I couldn’t find an answer in the SNAP category, so I’ll ask here too.
I’d be happy if you could give me some information.

Ocean data disappears with “Terrain Correction”

All the best,

Zuiko

Could you uncheck the “Mask out all areas without elevation” in the Terrain Correction UI?

Thank you for your reply.

I get what I want when I uncheck “Mask out all areas without elevation” in the SNAP UI.
However, even if I set “nodataValueAtSea” to “True” in snappy, I don’t get what I want.

Set “nodataValueAtSea” to “False”

I’m very sorry.
It was a typo.

I’ve coded it as shown below, but the ocean data has been lost.

parameters = HashMap()
parameters.put('demName', 'SRTM 3Sec')
parameters.put('nodataValueAtSea',False)
parameters.put('pixelSpacingInMeter', 10.0)
parameters.put('sourceBands', 'Sigma0_VV')
product = GPF.createProduct("Terrain-Correction", parameters,product)
