Since a few months we developed a new module called “View/Export Extended Data/Results”.
Here the full description: https://sarproz.com/manual/plot_par_mod.html
Please update your software version if you have an old one.
We are still improving it, so, you could find minor bugs/changes.
The idea is that you can do what you want, using…[Read more]

Not sure why you get date_1, can you paste an example here?
You should get the explanation in the first line of the csv file. Something like: “28 data entries plus 28 estimated movement entries ” and ” from 20081025 to 20091217 “.
This says that in the first series of dates you get the actual data, in the second series you get the model chosen to…[Read more]

The “Filter/Matrix visualization” function in “Scatter Plots” displays scattered data in matrix a form. In Matlab this is much faster rather than displaying scattered points directly. It basically consists in re-sampling your scattered data on a regular grid. This operation corresponds to a spatial filter. And you can actually apply a filter…[Read more]

Hi Asterios,
the general answer is: you would need to take a Sarproz course, where we teach exactly this, that is, how to judge and improve your results without any prior knowledge.
More in detail, always start with the easiest and default approach: linear trend, automatic and default choices. The software extracts and suggest you numbers,…[Read more]

CSV file fields:

ID – point reference id (sequential)
LAT, LON – latitude and longitude
SVET, LVET – sample and line, pixel SAR coordinates
HEIGHT – relative to sea level (m)
HEIGHT WRT DEM – relative to the external DEM (m)
SIGMA HEIGHT – height estimation standard deviation
VEL – deformation velocity in mm/year
SIGMA VEL – velocity standard de…[Read more]

* standard: usual standard unwrapping method, pixel by pixel, it suffers the usual drawbacks of unwrapping in presence of noise. If you mask an interferogram and you have disconnected areas, it’s not going to connect them.
* sparse LS: it uses sparse points and Least Squares to connect unconnected areas and to solve the problem in presence of…[Read more]

With respect to question 3, the “previous points” you pointed to are points selected by e.g. Amplitude dispersion index in APS?

the GAR works with a graph previously processed by the APS. so “previous points” are the points that you import in GAR from the APS module

The points selected with star graph are PS points, and points selecte…

Hi Zoe,
theoretically, it should work. However, it’s not 100% tested, you might get some problems. If this happens, there is no need to redo all the job. You can just remove the images you want to discard from the dataset.txt file. Then it will work

1. Does GAR always behave better than MISP? And do you recommend to use GAR in most cases?

the standard way APS+MISP is widely used and very robust. when APS+MISP is successful, you don’t need anything else. However, there are cases where it fails. In those cases, GAR can help

2.You mentioned GAR could detect strong movements which exceeds…

At the moment you can project the velocities using the Multi-Sensor module
Here a bit of description https://sarproz.com/manual/multi_sens.html
In the next future we will implement also the projected time series export

1. What the “Skip init Mask” means? When should it be checked?

it means selecting all pixels, not loading the initial mask

What the time series generated in this module is.

a time series object is a file that can be saved either in the APS module or in…[Read more]

The case of 2 sensors analysis is an advanced processing mode (as ERS and Envisat combination) that does not apply to your case.
You get only one reflectivity map per dataset.
If you are talking about combining different datasets (as ascending and descending tracks or different sensors) you can combine the geocoded (or orthorectified) maps in…[Read more]
