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.

hi

* if you want to cherry pick only a few pixels of interest, you can use this module: https://sarproz.com/manual/kml2mask.html to generate your own mask of pixels, eg by importing a simple list of geographic coordinates

* if you want display data (like amplitude or coherence) of cherry picked pixels, you can use this module (visualization…[Read more]

Hi Mahtab,
saving a selection of points does not mean saving the plot you are diplaying
when you save a selection of points, you save a 2d vector, where the 2 dimensions are sample and lines, independently from what you have on x and y axes in the scatter plot
the only choice you have is whether to save a color or not, as indicated here…[Read more]

Thanks, Dan.
In the meantime, I ignored the error and continued as usual. The spatial coherence looked fine. I will check the adaptive mask, images and interferograms as soon as the QPS analysis, which is currently running, is completed.
The SRTM DEM had a few Nan values. I’m not sure if that is the cause.
Best regards

Hi Janbu,
there can be a number of reasons for receiving that message, we need more infos to understand the case.
Generally speaking, even if for some reasons NaNs are in the data, that does not mean you cannot process and analyze successfully your data.
Please check the images one by one: do you observe black areas?
Did you generate the adaptive…[Read more]
