Ok I added those 2 paths to my system’s PATH variable. Nothing has changed. I still have the same issue.
The return is c:\temp\export. I have no idea what is wrong? I am sure its a small simple thing that we are missing, I just don’t know what it is.
If I open Cygwin64 Terminal and type snaphu, all the snaphu v1.4.2 commands show up. I did try to run the snaphu command there to see if it would work and it says unable to read configuration file snaphu.conf. Is there possibly something that needs adjusted in that file? I have not done anything to the file at all as of now. The screen shot and snaphu.conf file are attached.
I am stuck at this point, so anything you can do to help would be great and I appreciate your time!
The reason why you get the error message may because you have edited the snaphu.conf file in windows, the file snaphu.conf is unix format when created, if you edit it in windows, you must use notepade, emacs or vim which will not change the text format. Or you can use dos2unix manually change it format.
I understand the shanphu.conf file is in unix format. I only look at these types of files in notepad. For this instance, I have not edited this .conf file, only opened it in notepad to copy and paste the command to try to execute the unwrapping.
I have 2 computers. I copied over my exported work to my second computer and started over with the unwrapping process. I started fresh with the snaphu and cygwin download. Everything has been successful so far. The unwrapping is running. Let’s cross our fingers!
It’s still driving me crazy that my other computer won’t execute the unwrapping using snaphu? I have no idea what is going on.
I’ll follow up if everything works out ok with the fresh unwrapping process. Thanks for checking back in.
Ok, so everything worked and looks good! I am wondering what units the results are in though? Here are my steps to help. I used snaphu to unwrap and import the result back into SNAP obviously. The Range Dopler Terrain Correction was done before I exported as a Geotiff to view in ArcMap. This process says that the Pixel spacing is in meters. When I finally look at the resulting displacement image in ArcMap I have a raster value range that looks like meters to me, but I am not 100%. Are all results that are exported from SNAP in meters (as a default)? I understand you can do band math to change this, but is the default always meters?
Doesn’t applying phase to displacement run an algorithm across all pixels converting radians to units that would be used when measuring elevation (displacement in the ground)? What I want to know is what the units are after phase to displacement runs? I have a range that totally makes sense, especially if its in meters, but I have no way to tell what the units are.
