Unwrap question

[agruno]

Does unwrap step must do always then displacement will be calculated?

SNAPHU Unwrapping

Hi. I’ve been working with SLC tiles to generate the DSM over my study area. Well, so far everything seams Ok but the unwrapping process in SNAPHU (Ubuntu Virtual Machine) is running since yesterday morning (22 hours until now). I know the limitations of my computer (8GB RAM with core i7) but it seams that it is a no ending process. Has anyone here had the same problem? Is there any other tool (Free) to unwrappe rapped phases of Sentinel-1A SLC IW images in Windows? I would like to know if some…

Snaphu works fine. I’d mean basicaly?

Yes, Indeed the Unwrapping step most be done

Hello,

I’m a beginner in InSAR. I’m using the SNAP 5.0 to build a DEM. With the
tutorial “Interferometry tutorial with RADARSAT-2”

For the phase unwrapping using the SNAPHU algorithm, I’d using DEM-Generation-Pre-Proceisng-Snaphu.xml.
But, I’have a problem of connection. I have this error message:

The system can not find the path specified?

Can you guide me?

Thank you
