periz replied to the topic Maximum variable size allowed by the program is exceeded in the forum Sarproz Forum 8 years, 4 months ago
As checked together,
probably there were corrupted files in the optical images directory, changing the directory or deleting/moving the downloaded Google Earth files solves the problem.
We take the chance to remind here that GE files are downloaded in this directory: ‘../GIS/GOOGLEEARTH/’
with reference to the current site directory.

Hi Ivana,
that error happens while loading the image in the background.
The sw searches in the directory that you can change through the “layer” button.
If you change the directory, you should temporarily solve your problem.
To investigate why that happens, you could save the small area (with the same conditions as when the error occurs)
and pass…[Read more] -
periz replied to the topic original PS method in the forum Sarproz Forum 8 years, 4 months ago
Yasser,
In Sarproz you can implement almost everything. However, instead of having buttons as “PSI”, “SBAS”, or whatever, you have a series of tools/options that you can combine. Clearly, this requires understanding the operations. It’s more difficult than having predefined buttons, but I think it’s more powerful.
The 2 conditions you mention…[Read more]

periz replied to the topic original PS method in the forum Sarproz Forum 8 years, 4 months ago
Hi Yasser,
original PSI: STAR graph, no weights, no filtering
QPS: non-STAR graph, weights (spatial coherence), filtered phase
Anyway, Sarproz gives you the choice to combine those options and do what you want. You do not need to call what you do “PSI” or “QPS”.However, you have to be aware of the following: when you choose the option “coher”…[Read more]

Yuxiao,
can you check one image is detected as ascending?

periz replied to the topic building a custom graph in the forum Sarproz Forum 8 years, 4 months ago
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)
read the various QPS papers in the publications section -

periz replied to the topic SRTM DEM 30m in the forum Sarproz Forum 8 years, 4 months ago
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] -
periz started the topic Sarproz Release 2016.30 in the forum Sarproz Forum 8 years, 4 months ago
Changes/new features in the new Sarproz version:
– a new option is now available in the APS module: you can export time series directly from there, without processing the MISP. This option is particularly useful in difficult cases when the MISP analysis is not converging. This function is generating a TS object that you can load from the Time…[Read more]

periz replied to the topic changing the graph in the forum Sarproz Forum 8 years, 4 months ago
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] -
periz replied to the topic changing the graph in the forum Sarproz Forum 8 years, 4 months ago
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] -
periz replied to the topic KML export in small area processing in the forum Sarproz Forum 8 years, 4 months ago
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…

periz replied to the topic KML export in small area processing in the forum Sarproz Forum 8 years, 4 months ago
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… -
periz replied to the topic Google Earth Crashes in Ubuntu in the forum Sarproz Forum 8 years, 4 months ago
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] -
