Hello, I met a problem for making a coregistration by Enhanced spectral diversity.the message said that the generated image does not contain any pair.can anyone help me?
Can anyone tell me, i have already downloaded too many S-1 images but they are consist of black and white pixels none of the objects can be seen. What is this?
A problem occurred during the target product processing Type: OperatorException Message: Java heap space (S-1 Enhanced Spectral Diversity) Sir please give the solution
Thank so much for your great tutorial! Might I ask a question about the processing, when I use two satellite images all the slave images after computing Interferogram I can not see in the phase in the (the phase show nothing) Could you help me explain about that thank you so much for your time.
Best video Sir for InSAR mapping. As is this one, all processing explained in a well defined manner, please upload one video for further processing i.e. final displacement map generation. Thanks
We are glad you liked it. Right now we have no specific funding to produce further viedos in this direction, but we can kindly invite you to start a discussion on eo-college.org/groups/ and tackel the topic together with 6000+ registered users of the EO community.
Thanks, but I'm having a hard time when I do S-1 Back Geocoding step. No image is formed. When I try the next step, Enhanced Spectral Diversity, I get the message: Registration window width should not be greater than burst width 0. Remembering that the area where I'm trying to do interferometry has the original image mirrored, but I already fixed the problem. So the image is already deburst and is Ellipsoid Corrected. Does anyone have a tip?
I had this same problem. First make sure your software is completely up-to-date. If that makes no difference try switching around the slave and master image. I'm no pro but I think if the geo-coding doesn't work then the subsequent steps won't work either. Also loads of answers and different solutions on the STEP forum. Hope this helps!
I strongly recommend 32 GB RAM or MORE!!!, but it depends how many bursts you use. I know ram price is expensive but if you want to use SNAP and radar data, a lot of ram is necessary.
Honestly, your video is very useful for learning how to calculate InSAR result. But, I just give one advice, please make video using ALOS PALSAR 1 and 2, thank you
Covered here: TOPS Split, applying precise orbits, TOPS Coregistration (Back Geocoding, Enhanced Spectral Diversity), Interferogram formation, TOPS Deburst (to remove gaps), Topographic Phase Removal (to remove fringes which are due to topography) to obtain differential interferogram, Goldstein Phase Filtering (to remove noise from interferogram), Terrain Correction (Range Doppler), Exporting as Google Earth KMZ.
Thank you for your great video. Could you make another video on how to unwrap using Snaphu either using Cygwin or Linux Terminal. Thanks!

I am working on SLC data of other area but not able to get the orbit file. what I can do as I am not able to download S1 quality control
Thanks From Ecuador - ESPE
Hey..great video. My SNAP software is hanging a lot. Any solutions to fix it?
How can I choose the date of the images effectively? Like if the eruption starts on September 27 and ends at October 14. Thanks
In most instances we do a radar calibration step. (Radar-> Radiometric->Calibrate). Why is that not needed here?

Thank you so much for the explanations!!
You are welcome, feel free to check out the other courses available at eo-college.org.

Sir please give the solution
Same. Please let me know if you have fixed it. Thanks
@@shashankmahapatra9755 Yes I solved my problem.

that's great Thank you for that
Can we use the Sentinel-1Tops tools in the Radar Tab for other sensor data such as Radarsat2 or Alos2?
Thank you for the tutorial. Very helpfull for my my final exam in active remote sensing
This is really cool, thanks! Where can I learn more about the "Enhanced Spectral Diversity" step?
Also, would it be a mistake to apply the "TOPS Deburst" step before doing the interferometry?
Excelente video...
Thank you so much for this video... but what can I do if, executing S-1 Back Geocoding, always appears a messagge of "Java heap space"??
it cause your computer's space memory is not enough

Sure Sir..
Graet job can you please make video that explaine time series detection technique with snap
Thank so much.

I can not thanks you enough sir!
Thank you. Excellent!!!!
thank u sir so much
Thank you so much for this video...How many GB should the computer RAM for interferogram production be? Is 4 GB ram enough?
I tried this example with 4GB and it was "doable". Making smaller subsets from original image helps.
I strongly recommend 32 GB RAM or MORE!!!, but it depends how many bursts you use. I know ram price is expensive but if you want to use SNAP and radar data, a lot of ram is necessary.
