Topic: ASTER level 1B

Hi

I'm a new user to COSI_Corr and I want to compare results of glacier flow measurement obtained from InSAR technique with results obtained from COSI_Corr.  I have two ASTER images over that glacier but its processing level is L1B. I like to know is there a way to just compute correlation between two ASTER images?

Thanks,

Re: ASTER level 1B

Hi,

Yes, you can just compute the correlation between two ASTER images using the correlation tool, but you have to make sure that images are on the same grid. However you won't be able to ortho-rectifiy 1B images with COSI-Corr, you need the 1A level for this. Hence the correlation results will be affected by topography parallax errors.
