Anyone have done subsetting with batch processing in SNAP ? And which step should I do subset? When I am doing the SBAS, there are so many S1A products, it must be very time-consuming. So focusing on my study area may be more efficient. Thanks
Delete the second Read operator. Generally, only select one input for your graph. Then use the graph on multiple products in batch mode.
Graph files are always for processing one dataset at a time. The batch mode allows you to load multiple data and one graph which si applied to all of them.
I now see that you are using a SLC product. If you work with SLC data, you can create subsets using the TOPS Split Operator to select only a sub-swath and a few bursts.
Demonstrated here: The Order of DEM Creating Steps
You can even use the TOPS Coregistration to create subsets of coregistered image pairs.
Thanks, ABraun. I have applied subset operator to Tops Coregistration resulting image. But when I tried to apply Tops Deburst operator to the Interferogram Formation subseting result, an error occurred as follows.
My AOI is in IW2, and I tries to make subset to avoid java heap space, I try to make at the step of coregistration too, by decreasing the area.
So before making subset every SLC product need to resample ?,
I try it, but no data for IW2 or IW3, after resampling.
Would you suggest me any idea to cope with this problem?
I came back quite late.
I am trying to make displacement map of a particular area and following are the result of the process.
Please help me and suggest me to get the good result.
coregistration of two image
after phase unwarping, we can clearly noticed that the reasult has some error, because there is a big area having same displacement.
the source data are just before and after the heavy rainfall with some big landslide reasulting landslide dam too.
The result is not clear.
Please help me with this.
Thank you very much for your comment. My result is not good on the low coherence area. I was considering the process also. Is there any way to increase the coherence or solve this problem.
Is it ok to say that sentaline 1 A and B images are not good for low coherence area, for measuring displacement?
PolSAR may be good for low coherence images.
I am Shiva , I am trying to process the SAR Data using snap. actually my work area in IW 1 and IW 2 , where i don’t need IW 3 . actually I use SLC data as project is study land subsidence. Is there any way to merge both IW 1 and IW 2 so that i can process the data to get more details. thanks and waiting for your reply
