That is the incidence matrix of the images graph
each row is a connection between 2 images
each column represents an image
in a row, 1 and -1 locate which image to take with the plus sign and which one with the minus
interf = im1.*conj(im2) = a1.*exp(j.*ph1).*a2.*exp(-j.*ph2)

it should be the same bug reported by Ivana,
so, the solution may already be online

Hi Ivana,

thanks for the feedback, it’s a bug, we are uploading a fix, it will be ready online soon!

Hi Yasser, the reply of a similar answer is here:
http://www.sarproz.com/groups/sarproz-group/forum/topic/doubling-number-of-graph-connection-to-mst-estimation/

if your matrix is small is just because there were no interferograms with coherence higher than the threshold you used…

hi Yasser,
first of all, are you aware that you can put the software in “help mode” and receive some description for each module of the sw?
You can do this with the corresponding flag in the main window.

If you will do it, you will see that you only need to select a geotiff file to load a dem in such format.
The corresponding module and help file…[Read more]

For the coregistration the same applies:
the final aim is to have all images coregistered on the same grid.
If you do this by processing the coregistration via a STAR graph or via an other graph, the accuracy/precision may be different, but the final result will be the same: N images coregistered on one common grid.
By the way, up to this moment…[Read more]

Hi Yasser,

first of all, the concept behind: changing the graph does not correspond to a fully new analysis (like re-starting from the beginning). It’s just a different way to combine your data. Soon we will allow to change it also from within some modules to make it easier and more convenient.
If interferograms are missing it’s easy to detect,…[Read more]

If zooming and panning is an issue, it means that the area is not small.
The small area module allows you to do lots of low-level operations for data investigation.
If your aim is just browsing the data (and the area is not small), then you do not need the small area module…
If you just want to export part of your results: load a starting mask…[Read more]

Why do you need to export a kml from the small area?
The geocoding module allows you to download a background image from google earth.
You can look at your data in many ways and display all what you want, even in 3d.
If for some reasons you need to export the results in kml, you can still do it from the site processing, using the sparse geocoding module…

hi KM
GE has some issues in linux. If it crashes without reasons, you should re-install it. If it crashes when called from Sarproz, probably it’s because there was already an other GE instance running. We did not find yet an external solution for this. So, Sarproz offers an option to manage it “internally”: there is a flag for disabling the…[Read more]

Thanks.

new version with bug fixes is being uploaded

Hi Yasser,

the new available version should fix your issue!
let us know!
dp

Thanks,
for the second one, the fix will be released soon.
for the Sentinel one, we have passed it to the person in charge of Sentinel.
Now that you have started using the manage version module, notice that you can switch back to a previous release for overtaking new possible bugs.
Also, notice that you can input your email address in the advanced…[Read more]

Hi Yasser,
updates on the Sentinel code are very frequent: please download the last version and try again!

Santiago,

first of all, the amplitude stability index is a single number which gives a statistical property of the amplitude series. So, you cannot generate an amplitude stability time series, and those points are not amplitude stability values.
That said, in that picture you see the following things:
– big colored dots: the actual amplitude…[Read more]

Hi Ivana,

the time series module is exporting values which are equal to: residues + movement. And they are in [mm].
What to consider as movement is your option: velocity, non-parametric (smart), seasonal or whatever.
The frame located in the lower part of the “Time Series Module” is titled “Time Series SPACE Visualization and Export” and it…[Read more]

One particular I forgot to add:
the hybrid batch mode is now implemented in the SLC processing module and in the Site Processing for the following sections:
– Preliminary Analysis
– Preliminary Geocoding
– InSAR processing
Remaining sections are still under development.

SG,
you should make an effort and do 2 important things:
a. if you get an error, send us lasterror.mat and log file. from the log you sent us, you encountered some errors, but you did not submit us the lasterror.mat, so, we cannot help you
b. make use of the manage version module. first of all, updates have been released after March 6, and…[Read more]
