SNAPHU Unwrapping


#308

But those errors are corrected by the program, processing until the interferogram is obtained?


#309

No, as you continue with the processed products, the error persists.


#310

Sir, which software did you use to produce those two maps ? and the colour visualization pattern used too ?


#311

which software did you use to make the map and the other layout elements ? :slight_smile:


#312

the link which you have given, it is not loading.


#313

the materials were all moved to the EO college: https://eo-college.org/resources/insar_deformation/

hi, Abraun. Is there any procedure for to do a analisis of all the unwraping phases and have one value of displasament?


#315

well, you can calculate the displacements for different image pairs and then sum up the values of each pixel, as displayed in the last sliedes of the tutorial.


#316

what tutorial?


#317

It was mentioned above:
“Subsidence monitoring (NEST)“


#318

what is the procedure?


#319

I am referring to the slide where pins are used at selected locations to extract, compare and visualize the displacement for different time intervals.


#320

how do I add pixel to pixel.?


#321

either by extracting the pixel values of multiple dates and adding them in excel (please look at the slides) or by stacking all displacement bands and adding their values in the band maths.


#322

how can I remove the error of range and azimut?


#323

can you please describe your error?


#324

in some tutorials say that these errors must it is corrected, it is for decrease the error. But the these do not explain how to do


#325

not necessarily. You simply create an interferogram, filter it (goldstein filter), unwrap it and then convert it to displacement.

Hi, I have a problem, when I want coregister this sign appears


I dont can finish the process


#327

The input for this operator are split product (master and slave). Please look in the HELP for more details
