Dear periz,
Thank you so much for your suggestion, I think my result is pretty good!
On this basis, I would like to ask you another question, I’m processing data from two different sensor in one area, so I’m thinking how can I make sure I’m choosing the same reference point in both processing?
Many thanks! -

Hi,
I am planning to purchase/order a number of images for using MTInSAR for a bridge monitoring application. I am wondering which image parameters and modes are the best for monitoring the displacements over a longer period of time.
I would like to know the ideal polarization to use for vertical and horizontal movements in the bridge. Which is…[Read more]

Okay, I will try again by using 0.7 as the amplitude stability index. Using thermal expansion is because I’m processing Sentinel-1 data from 2014 to 2021, I think over this long time series, the results may be affected by thermal expansion. Of course, I will try your suggestion and don’t use it at this time!
Many thanks! -
periz replied to the topic APS processing in the forum Sarproz Forum 3 years, 4 months ago
the result is not bad, actually, it’s pretty ok
do not look at the value of the coherence in the temporal plot, that plot is useful only to look at the trend in time, to check whether there are some left signals that were not well modeled
more suggestions:
* u can take a lower threshold for the amplitude stability index, like e.g. 0.7. in this way…[Read more] -

It is not to mutch information to tell exactly. if You have sentinel 1 images stack, You may use first Smart 5 option (remove thermal manualy). Then You got data to analyse how big is tehe movements in AOI

Dear SARPROZ
I’m using SARPPROZ’s PSI to process the Sentinel-1 data. I have a question about APS Processing. After Preliminary analysis and Preliminary geocoding, I go to Multi-Image InSAR processing, I have three questions here:
1. I use Linear Trend=30, Height=100, Thermal expans=0.4 and after connections processing, the connection coherence…[Read more] -

janbu replied to the topic Exporting time series for a subset area only in the forum Sarproz Forum 3 years, 5 months ago
Thanks, Daniele,
I thought of the workaround in exporting to CSV, then GIS, etc., but I am not aware of ways to export kml with Time series.
Maybe this is something to consider for future developments?
Thanks -
periz replied to the topic Exporting time series for a subset area only in the forum Sarproz Forum 3 years, 5 months ago
In the time series module you can do mainly 2 things:
1. creating a new time series object, based on whatever set of points you want. For doing that (a) you need the data of the whole project to generate new time series and (b) you need to load the set of points using “load mask”. There you are free to create your custom point selection
2. loading…[Read more] -

Hi,
I have a Time series object processed a while back and now I would like to export a kml with time series only for a smaller area.
Is it possible? I have created a mask using the kml of the subset area but I think that doesn’t wok in the time series module.
Any thoughts?

Dear Professor Periz
I have been working with 33 Sentinel 1(mid 2019-2021) images on a Mater area of Radius 10Km in a mountainous region under small scale earthquake deformation study. In the APS estimation for the estimated parameters especially the Integrated Velocity shows spatial ramps in the inverted residuals estimation. I have gone through…[Read more]
