we are working with a temporal set of S1 GRD images and have entered the images in a stack as well as separately into the time-series tool. entered individually, we do get a time-line, however, the range is fixed from 0 to 100 so the intensity line is at zero. we have updated all plugins following the success of abhiyaam post on the Feb '19, but still no success. is there a specific plugin needed or any ideas on what might be wrong. we are using SNAP 7.0.3. thanks
thanks, we are unsure of what to press for the y-axis update. we can toggle the x axis range using the cursor position icon on the time series tool but not the y-axis. can you tell us what we are missing?
there is another problem that might be related. when we try to draw an ROI on the image using SNAP draw tool, SNAP freezes and we have to close SNAP with the task manager and restart. reading previous posts, we noticed this occurred in SNAP 6.0. we have SNAP 7.0 installed. is this a continuing problem in SNAP?
I tried to get temporal analysis of Sentinel data (time serie), the time serie tool is always blank. I upload the stack product, i tried to upload the separate products, I create pins, I even create polygone around my AOI but the same problem persists. Do you some hint about how to solve this problem?
On my analysis, I try to plot the temporal profil of a land subsidence. I created a stack in which I calculate the cumulative displacement over the study period masking the area of low coherence. please how can I get the temporal profil using the time serie snap tool.
Here is my stack image. when I click on filter, there is no effect
sorry, this description is from 2018 and no longer applies. SNAP is constantly being developed and adjusted. So if you take all geocoded displacement bands the the plots should work. It is also described like this in the tutorial I mentioned above which is from 2020.
Just out of interest: What happens when you input the stack, select the filter icon and there select displacement as band?
thank you for your reply. My period of study cover 4 years. So if i keep the the same initial image as master image for all the other images, I afraid about the decorrelation between the first (2016) and the other images with a temporal baseline more than 1 year causing inaccuracy of my result. Do you have any suggestion please?
I have no solution which works inside SNAP, sorry. Splitting a long period into small temporal baselines absolutely makes sense.
The only thing you can do at the moment is create a stack of terrain corrected displacements, set a pin and extract the pins’s displacement values to a table which you visualize in MS Excel, for example.
