one of the best video ever i have seen, you know i have been watching so many videos to how can i estimate land subsidence today after 2 years i succussed.
Its nice class, but how to get polygons during subset that like AOI_WKT,i ts where i will be gets? And now I will be doing land subsidence, so how will get more videos' for that process, my teachers using SNAP software
Thanks for this informative tutorial sir, is it possible to generate DEM contours with less than meter interval on Deformation area, I have to create elevation profile for small ponds in my study area. Thanks.
Thank you very much for the video. I can't put the "snaphu-unwapping" button on the graf building, although I have installed the plugin. Tell me what to do?
Hi There, thanks a lot for your video, this is great, just a question, I see you are running the unwrapping under Windows, did you check this values?, I thought snaphu doesnt run properly over windows and you had to run it under Linux
Thank you for the structured and very informative video! I started using SNAP recently and I notice that there's no option to do "Snaphu-unwrapping". Is that a Java class you added?
@@MrGIS I have installed the Snaphu-unwrapping tool in the system and also as a plugin but I still can't build that step in the Graph Builder, Do you have an idea of what can be happening?
Hello. Thank you very much for the class. I have a question, I'm generating an MDE but I'm not sure if I use IW1 or IW3. Some videos, the authors use IW1 and in others IW3, but do not explain the reason. Thanks.
One SLC scene is made of 3 subswaths. If your area of interest is in one of them you have to choose correct subswath. Every subswath has a different area coverage.
Actually no this method is only for 2 images. For calculating multiple images you need to use PSI methods. There is a plug-in for SNAP called STaMPS for this.
Dear sir, sorry, i mean, where did you get the exact coords? You were copying and pasting the boundaries of your area in the video. Where can I find that? My study area is in Naga, Cebu in Philippines.
A useful and helpful video I subscribe to your channel. Can we use the same workflow when processing the CosmoSkymed dataset? I need your email please for further request. Thanks
Thanks. SNAP support CosmoSkymed but haven't processed any skymed data yet. I think workflow will be the same maybe different parameters needed. You have to test it by yourself. Best regards.

I really appreciate your video, it's excellent.
What is happening at 5:50 ? No explanation of where you got that
can anyone tell?
And updated video would be helpful since this is 5 years old. Some of the tools you use are not there anymore or are renamed/moved
Its nice class, but how to get polygons during subset that like AOI_WKT,i ts where i will be gets?
Can this be done for subsidence study? Loved your tutorial ❤️
Yes but you need a lot of more scenes at least 20. You can do it in StaMPS. Read about this and persistent scatterers.
@@MrGIS Do you need Matlab to use StaMPS or is their less expensive option?

Thanks for this informative tutorial sir, is it possible to generate DEM contours with less than meter interval on Deformation area, I have to create elevation profile for small ponds in my study area.
Thanks.
Yes it's possible even up to millimeters but you need to use advanced InSAR methods and software like SarScape.
Thank you very much for the video.
just a question is there a simple method to convert the displacement into a vertical one , or to 3D displacement?
Yes you can export displacements map as raster and visualize it in QGIS
How to calculate volume using displacement in SNAP software
How can I produce the displacement values over time?
Excelent!!! what means the positive and negative sign?
Negative values mean subsidence, while positive values represent surface uplift.
Thank you very much for the video. I can't put the "snaphu-unwapping" button on the graf building, although I have installed the plugin. Tell me what to do?
And I have problem with Orbit Files.
very informative!
can this procedure be applied to estimate glacier displacement as well?
I’d rather recommend PSI methods.
Hi There, thanks a lot for your video, this is great, just a question, I see you are running the unwrapping under Windows, did you check this values?, I thought snaphu doesnt run properly over windows and you had to run it under Linux
Snaphu is available as plug-in in SNAP and works fine on Windows.
@@MrGIS thanks a lot for your answer :)
greetings
MrGIS
i can not process my unwrapped file
please will process this?
Thank you for the structured and very informative video! I started using SNAP recently and I notice that there's no option to do "Snaphu-unwrapping". Is that a Java class you added?
You need to install it as plug-in. From menu Tools--->plugins. Best regards.

Si sir what an amazing job I wender if you can prove or find void with this technologie and what if I send you the location and you help me

Can displacement be mapped using InSAR in SNAP? Or SarScape is essential?
At this moment no. You need SarScape.
So this method we called Dinsar, right? Not Insar?
Yes
Can we do this for multiple images.. ex- if w ehave to calculate subsidence for 5 years?
Actually no this method is only for 2 images. For calculating multiple images you need to use PSI methods. There is a plug-in for SNAP called STaMPS for this.
How did you get the exact coordinates of the area you were analyzing (in the subset part)?
Yes that's right.
Dear sir, sorry, i mean, where did you get the exact coords? You were copying and pasting the boundaries of your area in the video. Where can I find that? My study area is in Naga, Cebu in Philippines.
I've made shapefile with my area of interest and then in QGIS made WKT (well know rext) from it. There is a plugin in QGIS.
Is land displacement and land deformation is the same? And if so then can i use this method for land deformation study? Pls help
Can we use same process for land deformation?
@@shubhambhosale6028 yes land deformation and displacement are same.
@@vivekagarwal7134 thank you...
nice video. what the tite of the music backsound?
Actually I don’t remember 😀. Best regards.
It is possible if use 2 IW in S1- Tops corregistrstion, Like IW2 and IW3? And how to merge IW?
Yes. Look at my video for DEM creation th-cam.com/video/7w_-deMSRTs/w-d-xo.html

are you using pair scene?
Yes
@@MrGIS do you have tutorial on how to get the pair?
Check Alaska State Facility website there is a tool for best image pair selection.
@@MrGIS thanks
?
Thanks for the video
please can i get your email?
