periz replied to the topic No external Sentinel orbits in the forum Sarproz Forum 6 years, 6 months ago
Sarproz can be used also offline with USB dongles.
Those who use it offline manage everything manually.
You can in fact import your own external DEM. Or if you want to use SRTM, you just need to download it manually and place it in an SRTM folder. https://sarproz.com/manual/choose_dem.html
The same with optical images, you can import your own…[Read more] -

When Sarproz starts,
it checks for an internet connection.
If you have a proxy and if you have to configure your browser with the proxy infos in order to connect to internet, Sarproz will open up a window where you can input the proxy infos.
If this does not happen it means you can anyway connect to internet.
At that point, some ports might be…[Read more] -
periz replied to the topic Problems in starting working with Sarproz in the forum Sarproz Forum 6 years, 6 months ago
Hi Van Anh,
there are 3 windows in your desktop:
* main
* dataset selection
* slc data processingin order to see the “dataset selection” window populated with dataset, sensor, master and so on, you have to import data into your project.
you can import data into your project through the window “slc data processing”. just start clicking buttons in…[Read more] -
periz replied to the topic Graph Refinement Error in the forum Sarproz Forum 6 years, 6 months ago
– 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)?
* if after the graph refinement you import the SPMRautosave in the APS module, you do not need to estimate parameters anymore. you have already estimated them in the g…[Read more]

periz replied to the topic Graph Refinement Error in the forum Sarproz Forum 6 years, 6 months ago
– Should we keep points parameter and value exactly the same as in the previous APS (that’s what I have done?
* are you talking about the “points densification” section? no. you can choose any parameter/value. in fact, the idea here is that you can add as many points as you want. You have already run the APS module. So, you have processed con…[Read more]

Dear all,
in the past months we have been working on many small things and some major changes. It is not time yet to release the major changes, but it is worth to focus on the small improvements, now available in the new Sarproz version.
* VERY IMPORTANT: we have implemented some changes in the licensing system for Linux. Now you should be able…[Read more]

periz replied to the topic how to select a high quality reference point in PS processing in the forum Sarproz Forum 6 years, 6 months ago
The reference point is a critical step. If the reference point is noisy, this can limit the precision of the final result. If the ref point is moving or if it is at high/low elevation, it can bias the result. If the ref point is in a remote area, errors can propagate and make the APS estimation worse. The software performs some automatic tests…[Read more]

periz replied to the topic Undo step in the forum Sarproz Forum 6 years, 7 months ago
Hi Jaroslav,
surely, you can undo/recover lots of things in Sarproz (in fact, almost all operations).
In particular, you can undo “Residual fringes estimation and removal” by clicking on “reset flat/height constants”.
