chainshopping started the topic Questions about result from Time Series Module in the forum Sarproz Forum 2 years, 11 months ago
The first question is:
I wonder that what the displacement means in the kml shown in Google Earth.
Is that the displacement in LOS or vertical height change?The second question is:
I used this module to output the displacement trend into a csv file.
And then I found that there is another time series after the velocity series.
What is that…[Read more] -

hi,
this confirms my supposition: the code is there but it needs to be adjusted for your situation.
in order to modify it to match your data, we need 2 main things:
1. some data samples
2. some time.
We are not in the best moment of the year, so, I cannot promise you a very fast response.
We need to arrange some data sharing, please write to us…[Read more] -

Hi,
Thank you for your answer.
We are working with InSAR in some sites of Gran Canaria (Canary Islands). We have had good results using Sentinel-1 imagery but, now, we need to analyze a period not covered by Sentinel-1 (2009-2012). We have tried with ERS-2 but we got nothing. The catalog of Envisat ASA_IMS images for this window is very poor so,…[Read more]

hi,
long time ago we did process some envisat wideswath data, however, at this moment we are not aware of anybody using it and I suppose nobody really worked with those data after we developed the related code.
it means, the code might need some adjustment and at the moment I cannot tell you more. if you are not in a hurry, we’ll check it sometime…[Read more] -

Hello.
Are ENVISAT ASA_WSS_1PN products supported by SARPROZ?.
Regards.

periz started the topic Sentinel orbits timeout errors in the forum Sarproz Forum 3 years ago
Since a few days some users reported timeout errors while downloading Sentinel orbital data.
So, if you get such errors this is the post to read.
First of all, please consider that this is a problem on the ESA side (scihub.copernicus.eu). Not sure yet what is the cause, it could be some slow network response depending on the location from where…[Read more] -

https://www.sarproz.com/groups/sarproz-group/forum/topic/about-time-series/1. don’t use 3, it’s too short. use 5 or more

mehrdad-moshtaghivito-be started the topic How to fit a Seasonal model? in the forum Sarproz Forum 3 years ago
Dear,
Using 161 Sentinel-1 images, I want to estimate seasonality in my data. After doing APS based on a linear model, I want to add seasonality in MISP. I see polynomial and smart options. I couldn’t find a detailed description of “smart” in the manual.
1- What would be the difference between smart=3 and smart=5?
2- I want to estimate ve…[Read more] -

Awsome! Thanks

periz replied to the topic Failure playing “ding” and spatial coherence in the forum Sarproz Forum 3 years ago
We found out the reason: a hidden bug.
The number of interferograms was so high that, when splitting the data to contain the memory, the size of tiles became so small to generate an empty process.

periz replied to the topic Delete specific dates after APS in the forum Sarproz Forum 3 years ago
Hi Mehrdad,
your atmosphere is perfectly fine and no problematic at all. Values of the phase are close to ambiguity so you have a phase jump from -pi to pi but that is normal, the phase is wrapped. So, I strongly suggest you not to discard any images because you would just waste precious data. Generally speaking, unless you have huge problems (in…[Read more] -
mehrdad-moshtaghivito-be started the topic Delete specific dates after APS in the forum Sarproz Forum 3 years ago
I did APS estimation and my overall results looks good. However, I’m not happy with some of atmosphere phase estimation on specific dates like the enclosed one named “unexpected_atmosphere.jpg”. To me, it doesn’t make sense to have such an atmospheric phase over a city area. As I’m processing with Sentinel-1 and I have more than 60 images in the…[Read more]
