Can SNAP open CryoSat-2 ice thickness files

Dear ones,
is it possible to open
CryoSat-2 ice thickness (nc-)files
(from AWI -
in SNAP?

Thank you for assistance.

I’ve never tried.
But SNAP has a generic reader for NetCDF files. So, it might work.
You can try and let us know if it works.

Yes, it can. I have tried with one product ( and here’s the result:


Many thanks!

Related question - what could be a reason that after:
File → Open
the Reading process takes about 15 minutes and… nothing happends

PS.To be more clear, let me attach the error.
What would be your advice(s) ?

Hello Nelley,

I’m not an expert for the CryoSat data and don’t know why it takes so long to open it, but
the error you mention:

java.util.ServiceConfigurationError: Provider com.ctc.wstx.stax.WstxInputFactory not found
	at java.util.ServiceLoader.access$300(
	at java.util.ServiceLoader$LazyIterator.nextService(
	at java.util.ServiceLoader$LazyIterator.access$700(
	at java.util.ServiceLoader$LazyIterator$
	at Method)
	at java.util.ServiceLoader$

It has actually been solved in SNAP 9.
[SITBX-847] Error “WstxInputFactory not found” caused by s1tbx-cloud module - JIRA (

Are you still using SNAP 8, if so, I recommend updating it.
SNAP Download – STEP (

However, this error should not prevent SNAP from opening the data. It only affects the 3D World View.

…SNAP 9…
YES, it opened the file without the error, thanks!

Yet another question - it did it during 15 minutes,
are there solutions to speed up?

Sorry, I don’t know. Maybe @kraftek knows.
