Thanks, Dan.
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 -

Hi,
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:

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

Hi,
I am using windows. I’ve scanned through the files and haven’t noticed any obvious difference between the >1GB and <1GB.
I agree that is good to know if this is confirmed by others and hopefully there will be ways to go around it. Maybe a functionality from the Time Series Module to split the area in tiles (separate archives, maybe with a…[Read more] -
janbu replied to the topic Empty KML file in the forum Sarproz Forum 2 years, 6 months ago
Thanks. 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.

Thank you for the prompt answer. Yes, I was able to open the selected subsets kml individually. I have also followed your suggestion and read the kml as text. Based on the attached image, could you confirm is the links to the files are missing? I can of course provide more info or the file itself if needs to be checked. Would be interesting to…[Read more]

Hi,
Is there any size limitation on the exported kmz file for time series? The file I have created is ~ 1.3GB and when I try to open it, I get the message ” No results – empty KML file”. Note that I have tried to open a few single kmz tiles (within the structure of the kmz) and they seem to work. No error was returned in SARPROZ during the…[Read more] -

janbu replied to the topic Failure playing “ding” and spatial coherence in the forum Sarproz Forum 2 years, 12 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]

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]

janbu replied to the topic Exporting time series for a subset area only in the forum Sarproz Forum 3 years, 6 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 -
janbu started the topic Exporting time series for a subset area only in the forum Sarproz Forum 3 years, 6 months ago
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?

Yes. Not all of them as they are over 3000 (full graph), but they look normal.

janbu replied to the topic Warning MT Adaptive Mask in the forum Sarproz Forum 5 years, 9 months ago
Unfortunately, after creating the MT adaptive mask, I did process all the interferograms, selecting the “MT adapt” in the presets of the InSAR Params. Left everything else as default, processed the interferograms and created the coherence map with the results described.

janbu replied to the topic Warning MT Adaptive Mask in the forum Sarproz Forum 5 years, 9 months ago
Thank you. That was helpful.
I have proceeded with the MT adaptive filter, created the interferograms and generated the coherence map.
In order to get QPS (using the MT adaptive filter) I am assuming I would select points based on spatial coherence
When plotting the Spatial Coherence I basically get a map of all zero and in fact, no points can be…[Read more] -

Hi,
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.
What can be a reason for that?
The image is attached. I can provide…[Read more] -

Sorry…file named GRA4 is actually in the APS module (when reading the SPMRAutosave).
Here are attached the following the images. MISP7 shows the “error” in the deformation pattern.
