the point you picked up is just for visualizing the general picture from the distance, it’s not a real target

For some reasons we never noticed this post, sorry.
The variable you are mentioning it the Incidence Matrix of the graph (or network) connecting the images of your site/project. The graph is basically the way in which “interferometrically” connect the images you have. There are many ways to connect your images: you can use the star graph (with one…[Read more]

Hi, depending on the way in which you unzip your data, your data can be extracted in subfolders, masking the contents in a way that the software does not recognize them.
The standard way Sarproz recognizes sentinel data is, if the SLC folder contains directories called S1A_* … .SAFE or S1B_* … .SAFE

No. You can do the reprojection yourself once you get the final output from Sarproz

it surely makes sense to consider the temporal coherence of a point
but not for estimating height and/or velocity
the temporal coherence is used e.g. to weight the spatial integration of the APS graph

Thank you for your help.

I have another question. Does “weight data with the coherence” make sense if for the same point its coherence is the same on all interferograms, but the coherence may be different between different points?

hi

* Sarproz gives explicit messages about the options that are taken. if you read messages carefully, you should be able to understand whether interferograms are read, whether flattening is assumed and so on
* in any case, if you apply a standard processing, the phase is read from images and the flat terrain phase is removed afterward. you can…[Read more]

I work with wrapped phases.

you are not fitting a single line. you are fitting a planar surface (height and velocity).
with 4 images you can look at 3 interferograms. or you can calculate the average if in your particular case it makes sense. or you can neglect height and atmosphere if you are in the proper situation and assume that the phase content is just movement.
