Dear users,
We think that some updates with respect to the previous post can be useful since more than 5 years have passed.Q: What are the orbits used for Sentinel?
A: You can find useful information in the section 2.5 of this document at the following link:

periz started the topic Sentinel orbits timeout errors in the forum Sarproz Forum 3 years, 6 months 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] -

hi,
about the smart option:
https://www.sarproz.com/groups/sarproz-group/forum/topic/non-linear-deformation-question/
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
2. sarproz has a “seasonal trend” field. you find tutorials on that (small area, high buildings), e.g.…[Read more] -
mehrdad-moshtaghivito-be started the topic How to fit a Seasonal model? in the forum Sarproz Forum 3 years, 6 months 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, 6 months 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, 6 months 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, 6 months 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]

janbu replied to the topic Failure playing “ding” and spatial coherence in the forum Sarproz Forum 3 years, 6 months ago
Thanks. I’ve double-checked the graph and as per the image attached, is a full graph (with 11027 connections). The few interferograms I’ve plotted seems ok. Of course, I couldn’t manually plot over 11K interferograms but there are 11028 interferograms in the respective folder.
I’ve also tried to run it again using other filtering parameters for…[Read more]

periz replied to the topic Failure playing “ding” and spatial coherence in the forum Sarproz Forum 3 years, 6 months ago
1. you can neglect the “ding” message. it means the sound message could not be played. if you want to suppress it, uncheck “play sounds” in advanced parameters.
2. the coherence map generation was done in a few seconds. to me, it means no interferograms were included in the processing. since no messages are shown, it could be that your images…[Read more] -

Hi,
I am encountering the following issue. I have processed the interferograms with the full graph and created the “Coherence Map”. However, the spatial coherence plot is all made of “zero” values.
While the interferogram processing is “successfully concluded”, I noticed the “failure in playing ding” message. Could these be related? what could…[Read more]
