xleskom started the topic Decomposition LOS to E-W and UP-DOWN in the forum Sarproz Forum 7 years, 2 months ago
Hello,
I try to use SARPROZ for decomposition deformations in LOS to deformations in E-W and UP-DOWN. I have two dataset – ascending and descending (data from Sentinel-1A, Sentinel-1B).
I did the following:
1. I have exported time series in “Sparse Points processing” (for ASC and DSC data). I have exported time series like .tsobj files.
2. I…[Read more] -

It looks like thee answer posted here 2 days ago was not uploaded…
You have 2 choices when you find such an error
1) if you have recently uploaded the software, use the “manage version” module to switch back to a previous version

Thanks. This information is very helpful.

periz replied to the topic Reflectivity Min and Max values and units in the forum Sarproz Forum 7 years, 2 months ago
The reflectivity map is the average amplitude of all images.
The amplitude is measured in volts.
Values there are the output of a normalization.
Usually amplitude is plotted between 0 and 3, you can change the upper value in the advanced parameters http://sarproz.com/manual/adv_param.html
The actual maximum value depends on the strongest scatterer…[Read more] -

Hello Team,
I came across a parameter ‘Reflectivity’ is Load Mask option. I would like to know what are the max and min values possible for reflectivity. What are its units?

Hello, I have a error while trying to produce the reflectivity map, “undefined function or variable S”, I saw a similar problem in the forum with another variable and it was a bug, how can I correct it? Im using the last version of SARPROZ aug. 2017

Hello everyone,
After importing and coregistering the images, I started the preliminary analysis.
I am trying to calculate the reflectivity map in the Site Processing.
I get this message :Undefined function or variable ‘S’
Even after this message, apparently Matlab recognizes that it was calculated because then the box becomes green. But if I…[Read more]

the minimum required is estimating the time series using the APS module, then save the corresponding TS object, for both datasets.
when you have the 2 TS objects, you can import them in the multi-sensor moduel.
depending on what you are doing, you may want to process also the MISP after the APS.
here you see some exercises for the APS and MISP…[Read more] -

Thanks very much for the explanation.
Although, I have not really understood what I should do in practice (sorry, for me is a quite new world…and software).
I process the two datasets using Site Processing and then..? I use the multi sensor analysis module? Or I need to do something else in the middle?
Thanks for the infinite patience -

Dear Dan,
i want to geocode the change detection results.
The mat of 20090925-20091226 is located in the folder of CHDETECT.
However, when i gecoding the change detection results, it reminds the 20090925-20091226.jpg not found.
how can i generate the jpg from the mat?
Thanks,

A Time series object is a Sarproz internal data structure,
formed by a file with .tsobj extension and a folder.
Such structure can be optionally generated either from the APS module, or from the MISP one (APS and MISP are module for estimating time series models).
Alternatively, there is a module where you can generate a TS object without…[Read more] -

1. it is a surprise for me to discover that you can uncheck such option. we will correct it. anyway, it makes no sense. options are: * estimate, * read, * neglect. No checks corresponds to neglecting it.
2. neglecting a linear estimate (without other options) means not considering any movement. Not considering any movements, means that no…[Read more] - Load More
