I apologise for the delayed thank you.
We appreciate the help. The results, with carefully consideration of the above suggestions, were found really close to the expectation we had.
Thank you again and always congrats on the work being done. -

Hi Jaroslav,
surely, you can undo/recover lots of things in Sarproz (in fact, almost all operations).
In particular, you can undo “Residual fringes estimation and removal” by clicking on “reset flat/height constants”.

Hello!
Is it possible to undo some processing steps?
I am particularly interested to undo “Residual fringes estimation and removal” in case it didn’t gave the expected effect.j

About a. b. and c. just go with a. The other options are still experimental.
About thresholds, use the suggested ones as starting point. If you are not happy, try to rise the minimum value for being more restrictive. -

Thank you for the super fast response.
we are running now the data with what you suggested.Regarding the graph analysis and refinement, we have looked at it, but we do not understand the parameters exactly what they exactly they are for. Checking the manual it doesn’t really go in depth:

The result looks reasonable.
To check if the APS was well estimated, you the final “test” function. If the final coherence is high and evenly distributed, you are done. You can also plot the APS one by one to check for issues.
To understand if the height estimation range is correct, check the histogram of the connections residual height. You can…[Read more] -

Hello,
firstly we would like to congratulate you for the great work that has been put in the sarproz software.We would like to get a better understanding on analyzing the parameters and results of the aps processing. We are running 66 sentinel-1 images, from 2014 to 2018, over an area of nearly 16×16 km using a star graph.
In the sparse point…[Read more] -

Hi Dan,
I have tried killing everything, installing Matlab locally (rather than the University Matlab requiring network) and still have the same issue. When would be a good time for us to look at it via remote connection next week?Thanks!

periz replied to the topic APS processing and coherence in the forum Sarproz Forum 7 years ago
By looking at your images I have to make the following comments:
1. I am not sure if 0.7 ampl stab is a good threshold with 26 images. it would be useful to see the reflectivity map and the ampl stab map to have a better idea.
2. the range of height you are trying to estimate is too big. consider that you are processing connections (nearby…[Read more] -

Hi,
I have read a few topics on the forum on the APS module and I think I am getting there. However, I am still not sure which is the optimum for my analysis and if there is something wrong. I have been playing with different graphs, amp stab index thresholds, weights and so on. Often, I got into cases like this with the suggested…[Read more]

periz replied to the topic no window for site directory path selection in the forum Sarproz Forum 7 years ago
Hi Estelle,
unfortunately the Matlab version you are using does not allow us debugging errors.
My feeling is that you should kill everything, try again and it may work. If not, we need to look at that together via remote connection.

Hi there,
When clicking “select” in the “site directory” tab (within the data selection panel) no new windows is showing up. Therefore I receive the attached errors and I am unable to select a path for my dataset.
I would appreciate any help on this problem.Thank you
