I finally managed saproz for testing at computer cluster, so far working well.
But I got problem with coregistering S-1 data. From 30 images, only 1 was coregistered. For the others:
Reramping front-stitched SLC slave image on Date 20151104
Buffer size exceeding 200!!! abnormal!!! check your stitching strategy!!!
Resampling end-stitched SLC slave images on Date 20151104
WARNING:Index exceeds matrix dimensions.
WARNING: TOPS Post Processing for date 20151104 FAILED!!! Further analysis including this image might lead to unreliable result!!!
So I tried to use fitted images from FITTED/FORMER that seemed coregistered on the first sight. Indeed, they show strong vertical phase ramps within some (around half) of their interferograms. It seems it could be partially corrected by APS but I hope I can find a better way? Coregistration refinement failed as well with messages as:
Error in amp_corr(): wrong number of lines and samples for search image!
WARNING!!! coregistration of image 20141028 failed!!!!
image 20141028 will be discarded: check manually!!!
This may be also connected to SRTM (?) because it automatically downloaded SRTM data for only half of the scene. I tried to apply DEM in Geotiff over the whole area but it didn’t read the file (but the file is not corrupted, I checked it). My area is relorbit 32, swath IW2, size 6280×24260 pixels.
Thank you for any clues, hope to continue arranging sarproz in connection to sentinel-1 database as a basis of upcoming project possibilities..
it helps to use the previous version (Oct-6), here the interferograms are reasonable. But pay attention to phase jumps. I was lucky that my area does not exceed one burst… I also got this problem with the newest (Oct-28) version for most of the scenes and the interferograms were full of fringes (in the azimuth direction).
it seems it was some technical problem due to file permissions. I have solved it probably, now everything seems working well – the “stitching” finished with failure only at 2 images now. Only not sure why I still cannot load the DEM.. (does some chmod function is applied for DEM? because chmod will not work..)
I will probably finish my first s-1 processing during today and will let you know if i succeed or not.. so far it seems it works well and fast, using 23 workers and 96 gb ram it should be quite working 😉
