Hi,professor,
I get two parts of RST-2 images, the one is .rlsc format co-registered by GAMMA with .par file, the other one is raw data, (e.g. RS2_OK60115_PK140099_DK124064_W1_20101122_222717_RST2_VV_SLC). But the two parts of images aren’t during the same period.I hope to put them together to process.Is it OK in principle?
I create a SLC fol…[Read more]

hi,
i get another issue – it seems that Radarsat-2 gets wrong rotation – the GCP is set properly (manual match of airport object), but the whole image is shifted to the South while it should be to the North. Thus also DEM doesn’t match.
It seems to me that the software expects different mirroring/orientation of the image. Maybe a different…[Read more] -

Thank you, however it still doesn’t work:

periz replied to the topic Radarsat-2 data import in the forum Sarproz Forum 9 years, 4 months ago
sorry, the string _RST2 must be included but the directory must also terminate with _SLC
if you rename it e.g. RS2_OK55634_PK527325_DK467628_F23_20140808_163838_VV_RST2_SLC it will work -

periz replied to the topic Questions For PalSAR Process in the forum Sarproz Forum 9 years, 4 months ago
Hi Eric,
you have a dataset of mixed multiple polarizations (HH single pol and HH/HV multiple pol). As a consequence, the only choice is using HH. Would you have had a choice, the suggestion is never to use cross-polarizations for multitemporal analyses. In the future we may include polarimetric techniques and make use of all channels, but this is…[Read more] -

Dear All,
I am using the SARProZ generated on 10th April 2015 to process a PalSAR data stack. Then I got following questions:
1. the data is dual pol HH + HV, for mining site monitoring which pol is more suitable from your experience?
2. in older version it is always possilbe to specify 0.5 to Azimuth to sample squre pixel, but in this version…[Read more]

periz replied to the topic APS PROCESSING ERROR in the forum Sarproz Forum 9 years, 5 months ago
Thanks!
it was indeed a bug. But in the future we’ll remove the fine APS processing in the MISP module, because it’s not really needed.
The updated version (which is in fact coming with many new things -check the updates list!-) is already online.
cheers -

Dear all,
in the last Sarproz release a new module is included: “Manage Version” (button in “DataSet Selection”).
You can use that module to download new releases and also for switching between different sw versions.
This can be particularly useful for fast bug solving and/or beta testing of new features.
A full list of software modifications…[Read more] -
periz replied to the topic Radarsat-2 data import in the forum Sarproz Forum 9 years, 5 months ago
Based on the Radarsat-2 data we processed up to now,
the software searches for directories containing the string “_RST2”.
I suggest you at this moment to manually rename your directories including such string.
We may change the code later when we will confirm the naming convention. -

Hi Ivana,
first of all, QPS is a title which we used in a paper. However, as you have seen, Sarproz does not allow straight “PS” or “QPS” approaches. In fact, one can choose among many different options:
a. Images graph. The Star graph is adopted for PS-like approaches. For other approaches, you can choose the images graph better suiting your…[Read more] -
ivca-cz started the topic QPS with DEM in the forum Sarproz Forum 9 years, 5 months ago
Hello,
when asking how to make QPS, I got the reply that it is “APS with weights”. I understand it, but when I try to click on weights, I get a message that I cannot use the DEM and weights at the same time. Is it a way to overcome this, to make QPS in mountaineous areas?
Thank you, Ivana

Good we have analyzed and solved all matters.
1. if in a dataset of 15 images there are 2 or 3 bad images with high shifts, it is useless to process all of them with non-standard parameters: firstly, one has to coregister the dataset with standard parameters, after that one can deal with the faulty images one by one searching for the proper way…[Read more]
