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, 3 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, 3 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 all,
after more than one year of pandemic, lockdowns and all related issues and troubles, we want to summarize a bit what is going on about Sarproz.1. SARPROZ COURSES.
As you know, we have switched to an online remote mode for delivering Sarproz courses. Next SAR/InSAR Sarproz course will be held in June. Please write to courses at sarproz…[Read more] -

Dear Professor Periz
Thank you for your respond, I do really appreciate your attention on the matter and I am really sorry for being in the middle during a very busy time. I will write to support!
Thanks a lot!

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]

Now it is totally clear to me. I appreciated all of your answers, thank you!

no.
ASI and reflectivity maps are calculated using the set of images of your dataset, independently from the images graph (which is something related to operations involving pairs of images)
this means, if you change the set of images, you have to reprocess ASI and REFL maps -
bridgetwang replied to the topic in the forum Big dataset processing 3 years, 4 months ago
Thank you so much for the prompt reply. Now I understand where the problem is.
So does it also mean that, everytime if I change the graph e.g. from STAR to Full graph or MST, I should re-process the ASI for the current graph?
-
periz replied to the topic in the forum Big dataset processing 3 years, 4 months ago
if you select your points based e.g. on the amplitude stability index == ASI > 0.75 and you get the same amount of points in subsets A, B and C, the explanation is only one: ASI is the same in the 3 datasets.
Instead, for each subset you have to re-process the ASI so that you will get 3 quantities: ASI_A, ASI_B and ASI_C

Dear Prof. Daniele,
I had asked in the forum that I coregistered and processed a long time series dataset including 280 images, and then I changed the “Dataset.txt” to process different subsets individually in one project. Here is the question link:Big dataset processing
The 3 subset is 2010-2012,2012-2014,2014-2016, and the whole dataset is fr…[Read more]

vinphe replied to the topic Incidence angle – SARPROZ compiled version in the forum Sarproz Forum 3 years, 5 months ago
Hi,
Thank you for your reply. We will have to analyze large areas, so a per pixel value is of interest. Is it possible to have a value at the 4 corners of the area of interest to interpolate the incidence angle per pixel instead?
