I am not sure if I am doing something wrong or it is a problem related with the software. I was playing/learning quite well with the module Spare Point Multi-Image InSAR Analysis (within Small Area Processing) until I decided to select an area somewhat larger. I selected the area, dealt with the Sparse Point selection and then with the Spare Point Multi-Image InSAR Analysis. Keeping the same PS Processing and APS parameters, I had different results. I decided then to process the former smaller area again but this time I had a glimse: XData cannot contain duplicate values. Should I had to manually remove some file/s before changing the size of the area of study, or is something that have to be done by the software?
Attached will find the last error and last log file
I am not sure I understood well.
Tell me if I am right:
– you are in the small area processing
– you processed insar time series (multi-image insar)
– you did not close the time series processing module
– you changed the area (with select area)
– you went back to the time series processing module
– there you got the error
If this is correct sequence, I can understand the error, and we will include an extra check in the future. In other words, before changing the area, you should close all small area sub-modules or you will have an incompatibility between data loaded in the different windows…
No, the sequence is as follow: I closed multi-image insar, changed the area, processed time series again and then I had strange results. I decided to close all the modules (closing down SARPROZ), re-start it again, follow the normal procedure up to multi-image insar, include parameters, press go and then the glimse appears when press results.
Forget the above conundrum. All is solved now (but I do not how).
Anyway, the same set of sparse points at different size areas but with similar time series parameters behaves different. Is this normal. If yes, why?
