Hi I do get an error message while forming an interferogramm:
Interferogram: Source products cannot be InSAR pair: one with EAP phase correction, one without.
org.esa.snap.framework.gpf.graph.GraphException: Interferogram: Source products cannot be InSAR pair: one with EAP phase correction, one without.
I tried to apply the eap phase correction to the first file, however this fails also.
The files I’m using are:
I am trying to create an interferogram from two SLC IW images (S1A_IW_SLC_1SDV_20141012T051732_20141012T051759_002792_003250_0D85 and S1A_IW_SLC_1SDV_20150703T051729_20150703T051756_006642_008DDA_8CF4) and I get the same error as @vhelm, namely:’ A problem occurred during the target product initialisation. Type: OperatorException. Message: Interferogram: Source products cannot be InSAR pairs: one is EAP phase corrected and the other is not. Apply EAP correction.’
I tried applying EAP phase correction to the 20141012 image but this does not work as well. I am using the latest SNAP toolbox (2.0 beta 8 (14.10.2015 20:13) ).
EAP correction is not included in the snap2stamps scripts.
My quick suggestion is not to consider data prior to 15 March 2015.
Another option is to apply EAP correction to older data.
My suggestion for newer SNAP versions is to include such correction automatically, as SNAP can detect which data need it.
However, I would have expected to see the same issue on the previous pair, 17 Feb, for which apparently SNAP cannot download the DEM.
