I wanted to report an issue with the “Grab Area” feature (subset dataset extraction → selection and extraction). It doesn’t seem to be working as expected. Regardless of the area selected, the system assigns the value 1 to each corner.
The extraction works correctly only when the values are entered and filled in manually.

Regards

I’ve been using the “Classification Tool” for a long time to select points on the reflectivity maps and plot the respective coherence matrix. However, I’ve noticed that this functionality is no longer working. When I click on the reflectivity map, the coordinate selection option doesn’t appear anymore—the image just zooms in instead.

In the meantime, I ignored the error and continued as usual. The spatial coherence looked fine. I will check the adaptive mask, images and interferograms as soon as the QPS analysis, which is currently running, is completed.
The SRTM DEM had a few Nan values. I’m not sure if that is the cause.
Best regards

I am trying to create QuasiPS (or Distributed Scatterers) and, as I usually do, before creating the interferograms I am running the MT Adaptive Mask. Running the Probability tables (leaving the default settings) I get all raws with the following notification:

While the new repository is implemented, you can try using the Python script sentineleof (https://pypi.org/project/sentineleof/).

Hope this helps.

I am using windows. I’ve scanned through the files and haven’t noticed any obvious difference between the >1GB and <1GB.

I did a few tests creating kmz of different sizes (by filtering the n. of points) and wanted to circle back the results here, as it may help others with the same issue. I found that files <1GB are working fine, while files over 1GB keep returning the above-mentioned error.

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 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]

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

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?
Thanks

I have proceeded with the MT adaptive filter, created the interferograms and generated the coherence map.

I am processing a data set 0f 24 Sentinel images with a Star Graph for the image combination.
APS results show the lowest value (near to zero) at the date of the master, which I found weird. Changing the date of the master, I still get the lowest value at the master date.

– Regarding the first question/answer, is that valid also if after the Graph Ref (GRA) we recompute the atmosphere in the APS? Is that recommended (or when it is recommended)?
