Good afternoon everyone, I want to ask you a question regarding this post (of muhannad), and it can be very basic but I am an archaeologist and the ASCII format escapes my knowledge. That e+02, would correspond to the number of decimals that moves to the right? that is, e+01 in an ASCII case -1.123 would be -11.23? and if it is e+02 would it be -112.3?
It’s the scientific notation : e+02 means 10^2 which is 10x10=100.
You multiply this number by -1.123 : 100x(-1.123)=-112.3. And so on.
-1.123e+01 is -1.123x10^1=-1.123x10=-11.23
-1.123e+02 is -1.123x10^2=-1.123x10x10=-1.123x100=-112.3
-1.123e+03 is -1.123x10^3=-1.123x10x10x10=-1.123x1000=-1123
If you want it’s a shift of the decimal (.) to the right.
I have never paid attention to the internal values of the heading. This is a good question for the developers.
However, once the StaMPS processing is completed and you plot the results on a map, points match features, so I am not sure what happens on the StaMPS export operator, but the final results looks fine to me, as each point has individual lat/lon coordinates, but maybe on your case is different.
Feel free to ask your questions to the developers, indeed, and keep us updated. Now probably we are all curious
,
And after that when I run stamps(1,1) from matlab I’ve got an error mentioned above,
any suggestion would be helpful,
Thank you for your fast replay,
Thank you both,
Yes, everything is up to date,
I will have to do deeper look on matlab,
I use matlab R2018a, it shouldnt be a problem I think, witch version you guys use?
Thank you very much once more, it is good to talk with someone about this,
I am not sure if this causes the error, but the master date should not be included in the slaves, because otherwise it is coregistered with itself and produces a null inteferogram (we discussed this here).
But I have seen workflows where this is the case and it didn’t cause an error at least, simply a single color interferogram at this point.
I simply delete interferogram 20190531-20190624 from diff0 and rslc folder witch has zero amplitude, by your suggestion.
Is that allowed, or I have to go back to SNAP and redo again all stack without image 20190624?
Thank you very very much,
Cheers,
very good. If all interferograms were loaded correctly I don’t think deleting the master one will cause an error at a later step within StaMPS. Go on, with each step separately [stamps(2,2), stamps(3,3),…) and see if you encounter any strange messages. If no error occures, you are good to go!
