You can take into account several factors to derive the deformation in the time series (a linear trend, several non-linear components, also including the thermal-related factor). To know more about the different processing strategies and the functions of the software, I suggest you to participate to the next online course organized by our partner…[Read more]

thankyou for your response
can you explain more about related to the model used to infer the deformation?
especially calculation to infer the defromationregards

Hi, the first set of data is related to the time series of displacement, while the second one is related to the model used to infer the deformation.

Dear Dr. Perissin,
How can I extract the LOS displacement data from the attached CSV file to create a graph curve like the example?
Why are there two columns labeled yyyy_mm_dd_VV in this file? what is the difference? -

Please zoom in and keep clicking on points
you will see the time series
the point you picked up is just for visualizing the general picture from the distance, it’s not a real target

Good day!
I would like to address my issue in doing small area processing and any other PS-InSAR or InSAR processing in SARPROZ, after i process my temporal data i proceed in displaying or exporting my data in Google Earth, the PS Points can be displayed but after i click it there’s limited data and there’s no linear graph that shows displacement…[Read more]

For some reasons we never noticed this post, sorry.
The variable you are mentioning it the Incidence Matrix of the graph (or network) connecting the images of your site/project. The graph is basically the way in which “interferometrically” connect the images you have. There are many ways to connect your images: you can use the star graph (with one…[Read more] -

Hi SarProz Team,
Could you clarify why the one edge of the orthorectified image doesn’t look like straight? Is it related to the height of the features at the edge and solving SAR distortion effects?
Thanks,

periz replied to the topic Data import in the forum Sarproz Forum 3 months ago
Hi, depending on the way in which you unzip your data, your data can be extracted in subfolders, masking the contents in a way that the software does not recognize them.
The standard way Sarproz recognizes sentinel data is, if the SLC folder contains directories called S1A_* … .SAFE or S1B_* … .SAFE

Dear Everyone,
I have a rookie question regarding S-1 SLC import. I have over 300 images per geometry ranging 10 years that I have downloaded from the Vertex server. Same path, two-three different frame numbers that cover my AoI, to maintain a roughly 12 days revisit. I try to perform PS-InSAR.
They come as a .zip folder, but I figured from the…[Read more] -

No. You can do the reprojection yourself once you get the final output from Sarproz

yanakhbarp started the topic Sentinel 1 IW SLC Product Reprojection in the forum Sarproz Forum 3 months, 3 weeks ago
Hi there, the Sentinel 1 IW SLC Product comes with WGS 84 Datum. Is it possible for SARPROZ to do a Reprojection from WGS 84 to ITRF 2014? The motivation is that the available CORS GNSS Measurement over my study area works with ITRF 2014 Datum, so I would like the PSInSAR result to share the same datum with the ground truth.
Many thanks for the help.

periz replied to the topic In Multi Image InSAR processing, where SARproz will read the phase from? in the forum Sarproz Forum 3 months, 3 weeks ago
it surely makes sense to consider the temporal coherence of a point
but not for estimating height and/or velocity
the temporal coherence is used e.g. to weight the spatial integration of the APS graph

yaoshuyi replied to the topic In Multi Image InSAR processing, where SARproz will read the phase from? in the forum Sarproz Forum 3 months, 3 weeks ago
Thank you for your help.
I have another question. Does “weight data with the coherence” make sense if for the same point its coherence is the same on all interferograms, but the coherence may be different between different points?
