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 r…[Read more]

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…[Read more]

Could you give me suggestion and opinion from my PS results?
1. Why residual height results still rather high? In APS parameter I put -50 x 50

2. Why thermal expansion is not linear with building height ?
I have assumption, I dont know it’s true or not.
-Right side area is more density than left area, so in right area thermal…[Read more]

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 tes…[Read more]

I have sent in your email perissin@purdue.edu,

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.

Best Regards,

Ana

I have included error file below,
Matlab R2013a was installed

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.

Best Regards,

Ana

I have finished all my processing procedure. Several days ago, it was Ok (No error).
I just want to know the deformation trend using “GEOCODING” toolbox. But If I select the point. something wrong.
Please, find attcah file below.

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?

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…[Read more]

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…[Read more]

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?

Best Regards,

Ana

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.

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…[Read more]

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.

Please, find attach file below

To have point match in GE, I have done first step to choose GCP that align in SAR image. you can see in 1.jpg (attach file). I think its SAR image and GE match well. After I choose small area processing, the shifting problem still unsolved (2.jpg file). As far as processing, I still can not find where is the Href box located.…[Read more]

I make scatter plot in SARPROZ, and select interested area in “Small Area Processing” tool. I have some problem to understand:
1. Point that high coherence value must in building area, but in this result, the Google Earth Image and Point don’t match exactly. Based on your tutorial, your GE image very clear, but from my result GE…[Read more]

I have some problem for small area processing. I use 20 ASAR image. If I choose interest area and try processing for co-registration, the matlab comment show me message that my area too small to match.
And how is minimum area can be processed by SARPROZ software?
Please find attach file below.

Best Regards,

Ana

I just solve my problem. Now, I can understand why the SAR image (Refl.map) like that.
Thanks very much

Ana

In your tutorial you say that if we are not really satisfied with the automatically selected point. Therefore, we are going to select one manually. Depending on the available data and the resolution, there are different strategies for selecting good tie-points for geo-coding.

For GCP point problem , I want to make sure that…[Read more]

I have some problem lists below:
1. I make GCP itself from google earth, in left-below from interest area but in Refl.map value why the GCP still in right-below of image? It looks like I don’t geocoding yet. But from your tutorial, you have not done geocoding too. I think, GCP point in Refl.map must in left-below. Am I miss some…[Read more]

Based on your paper https://engineering.purdue.edu/~perissin/Publish/07BioGeoSARDossena.pdf
You have result in order to increase the effective temporal baseline, more connections can be added to the MST. By e.g. doubling the number of graph connections (selecting the most coherent interferograms not yet used).
