Dear Ivana,

Thanks for advise and explanation, I get it

Dear Prof.Daniele

I got results from CSV file, but I cant find residual Height value.
What mean of “HEIGHT WRT DEM and SIGMA HEIGHT” in CSV column?
If Residual Height = Height – External DEM, Could I say that Residual Height = HEIGHT – HEIGHT WRT DEM (based on CSV column)

Besides that, in SARPROZ, how I can generated and get data “phase residual”. I want to know the value before and after APS processing.

Best Regards

Ana

Dear Prof.Daniele

From the problem above, It is SOLVE and OK.

But, After I re-processing my data, Any problem occur.
I used 20 ENVISAT ASAR image and using STAR-graph (before I used MST-graph).
In Site Processing toolbox, I have done and have very good result based on coherence graph (See image).
I want to generate Geocoding, it’s mean I must use Small Area Processing toolbox after that.
List of problem:
1. Why I can not process “Sparse Point Multi-Image under Small Area Processing toolbox”?
The matlab window show to me that “compensating master error” ( see image).

2. And If I was continuing in “geocoding under Small Area Processing toolbox” and I pick one point, the error in data selection occured

Any kind step that I am missing?

Best Regards,

Ana

Dear Prof.Daniele

I would like to ask,
1. based on what we can conclude that SAR has good results and can use the APS options ( IP , IR , Tri.IR ) in the area of ​​the case study ? Can you attach some paper / reference, in order to we can understand more each parameter. It is not enough to judge like your say that “the APS looks ok and the test shows a homogeneous high coherence in your analyzed area, then you can proceed further and be assured that everything is working well used IR”

2. My case study area of lowland , how do you think if I ignore Ext.DEM and replace Matr.Coher.Win 5×5 (I want to do filtering)

3. In the weights option, could you tell me what is different about “none, coher , amps” . Whether this affects the results of processing APS?

Best Regards,

Ana

Dear Prof.Daniele

I have selected point first, after I select it and using Data Series, any tranding image will be appeared.
But, the fact, If I select point, the left-below box show me “Error in data selection”.
The image example from Def.Trend I have included before.

Dear Prof.Daniele

I have included error file below,
Matlab R2013a was installed

Dear Prof.Daniele

I have tried another parameter likes Deformation Tranding (Def.Trend) and Cumulative Displacement (Cum.Disp) to get time series deformation graph data. But always any error If I check “Data Series” tools, in other word is nothing image ploting to be resulted.

Dear Prof.Daniele

I used ERS-2 for processing, I want to co-registration, but for \”set Orbits\” option, the precise orbits unavailable. Any suggestion what must I do?

Dear Prof Daniele,

I choose second area to analysis. Based on my result, have you think that it reasonable or no? Please, find attach file below.

In APS estimation, Any parameter unknown, could you explain what is “Estimated Parameters like, R r0 ds, Flatten, R and DSF” also in “Processing Parameters like Scattering Centers and Polynomial Order” ?

Best Regards,

Ana

Dear Prof.Daniele

I have tried using another parameter for “Images Graph=Delaunay Graph”.
In APS processing I used DSxDL is 0x0 and matr.Coher.Win is 10×10 also used I.P. (Inverted Parameters) options. Hope you give me suggestion for results.

Any other question
After I made scatter plot, I was rather confused about analysis relation of amplitude and temporal baseline. Could you tell me how far it was very contributed in PSInSAR?

Please, find attach file below.

Dear Prof.Daniele

Another question.
I try to compare with GPS statiun (LIKNstatiun that I plotted in GE). This statiun have distance around 8km from my area. I think its shape almost same. So, Have I considered it or no?

Dear Prof.Daniele

I have processed almost 3 square-kilometer area.
Hope you give me suggestion to increase good results.
How about my second question (GPS data). Could you explain it?

Please, Find attach file below.

Dear Prof.Daniele

1. For make sure that PSInSAR correct processing, how many factor must be considered besides from the attach image?
And how about your opinion based on my results
2. From PSInSAR, Must I have GPS data for verification? Any likelihood below:
(a). I have GPS data but the statiun far away from my area (equal to 8km)
(b). I did not consider about GPS data for PSInSAR analysis.

Ana

Dear Prof.Daniele

I have done to choose Href, prof.
From the first step about geocoded refl map, I must re-process it again or no. Because from GCP selection, the SAR coordinat and Geo coordinat in GE it looks like match well.
