periz replied to the topic Combine different geometries for decomposition of LOS motion? in the forum Sarproz Forum 7 years ago
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] -
periz replied to the topic cumulative displacement in the forum Sarproz Forum 7 years ago
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] -
periz replied to the topic Combine different geometries for decomposition of LOS motion? in the forum Sarproz Forum 7 years ago
Ciao Cecilia,
yes, you can, through this module: http://sarproz.com/manual/multi_sens.html
Unfortunately the module is a beta version and not all functions are available.
Anyway, you can align your datasets, select ascending/descending corresponding points, then plot the projections.
You have firstly to process asce/desce datasets separately, then…[Read more] -

Hi Janbu,
I do not know myself the Doris/Roi-Pac formats, we should wait for an advice from someone else. But the files you attached above look like coming directly from the data provider (or at least they look like in the same format). So, try the following: untar you file in a sub-directory (like “D26075_1_A3_26420”) inside the SLC folder and…[Read more] -

to detect ASAR images, Sarproz searches for ASA_… files. they can be in subdirectories or all in the SLC folder

periz replied to the topic Height standard deviation in the forum Sarproz Forum 7 years ago
yes, it’s a measure of the accuracy of the height estimation
it is calculated based on the distribution of the dataset parameters (normal and temporal baselines) and on the options you selected to estimate the time series parameters (as velocity and height) -
periz started the topic Sarproz Release 2017.4 in the forum Sarproz Forum 7 years ago
Dear all,
in the past months we have changed many small things, the full list is available in the “Manage Version” module http://sarproz.com/manual/manage_version.html after downloading the new updates.
Here a few highlights:
– all extended export functions have been updated, now offering 2 options: geocoding or orthorectification. In the pas…[Read more] -
periz replied to the topic cumulative displacement. Load mask error in the forum Sarproz Forum 7 years ago
Yes, velocity and deformation trends are the same.
The cumulative displacement is saved when you do a non-linear processing.
You do a non-linear processing if you input a value in the “smart” box in the time series processing options.
That value corresponds to the length of a temporal filter. So, the outcome is a non-parametric estimation of the…[Read more] -
periz replied to the topic cumulative displacement. Load mask error in the forum Sarproz Forum 7 years ago
1. select a set of points via load mask using e.g. the temporal coherence or the amplitude stability index. it does not make any sense to select points based on cumulative displacement
2. then check your results via histogram and scatter plots modules. you can check the histogram of the cumulative displacement to understand what is wrong. then…[Read more]

periz replied to the topic resampling kml mapping in the forum Sarproz Forum 7 years ago
Use this module: http://sarproz.com/manual/xplot.html
1. load points via load mask in site processing
2. open the scatter plots module
3. choose latitude as y axis, longitude as x axis, velocity or any other parameter of interest as color
4. press “go” in filter/matrix visualization to check what you are doing
5. press “geoout” in the same frame…[Read more] -

Looks like we overlooked your post…
Did you solve the issue?
You don’t need to increase the search pixel: the initial cross-correlation is used to estimate and remove the big shifts. Increase the search pixel only if you think that shifts change significantly within the image (e.g. because of a huge stretch).
We cannot debug your lasterror…[Read more] -
periz replied to the topic APS Processing parameters in the forum Sarproz Forum 7 years, 1 month ago
that’s exactly the purpose of using a GCP. Anyway in Sarproz you can correct such shifts also later with the geographic corrections module

periz replied to the topic APS Processing parameters in the forum Sarproz Forum 7 years, 1 month ago
I don’t see easily a reason for that residual ramp. This would deserve some deeper investigation. The results anyway are now much better.
About the geocoded reflectivity map: are you keeping a 1×1 downsampling? Otherwise, u’ll degrade the resolution. The mean kml generated from the GCP module is downsampled 8×8. That map is generated just to give…[Read more] -
