bala started the topic Problem with GCP selection and Geocoding in the forum Sarproz Forum 7 years, 3 months ago
While I am doing GCP selection through “Keep current orbits” sometimes it’s giving zero value for Ext. DEM height and When I am doing this step through “Ext. DEM” GCP point is selected from out of the study area. In both cases, geocoding is not done perfectly. Here, I can’t select pixel by using “Force my pixel” option because of I am working…[Read more]

Yuxiao replied to the topic Sentinel-1 co-registration warnings in the forum Sarproz Forum 7 years, 3 months ago
Hi V,
For the data corruption part, it is a known issue. In sarproz we implemented several ways to detect corruption of SLC images. You should get warnings/errors if they are corrupted.
In the case where no warnings/errors were given, it is always helpful to check:
(1) The JPGs of SLCs in EXT/yyyymmdd folders and in FITTED folders. If the…[Read more]

Hi Yuxiao,
I am using the newest version.
I solved my problem with co-registration. I’ve just realized that it was due to corrupted downloading of Sentinel images.However, do you have some general recommendations or tips to get reliable results from Sentinel data processing (parameters and so on)?
I am doing processing Sentinel 1 data over…[Read more] -

Hi
I have been trying to import (Get Contents) Radarsat-2 images in SARPROZ, however, I have been getting this message: Error in rsat_meta(): can not find RSAT xml file!
This issue only occurs for the Radarsat-2 images that (for some reason) do not include the file (product.kml), but the file (product.xml) is included in all Radarsat-2 image…[Read more]

Yuxiao replied to the topic Sentinel-1 co-registration warnings in the forum Sarproz Forum 7 years, 3 months ago
Hi Jaroslav,
Yes and No. A few explanations:
Yes Part:
1. My experience is that spatial baseline is not a big problem for tops in general. Since (a) tops has such good control in its orbits precision & accuracy; (b) the baseline is usually quite small (within 200 meters in general). So geometric decorrelation is not really a big issue here.…[Read more] -

Hi Yuxiao,
Doesn’t master choice influence co-registration process a lot? I have often noticed, that outcome may be significantly improved just by choosing right master.
Additionally, I’d like to ask about Sentinel master choice methodology. Usually, master is chosen such, that the dispersion of the perpendicular baseline is as low as possible,…[Read more] -

There has been a minor update to S1 TOPS. Below is a list of the new updates.
1. In the older versions, for the SLC folder, when there are two adjacent scenes that could be merged, the code will create a new “merge folder (that will end in SRPZ.MRGE)” that stores necessary new files. When coregistration finishes these merge folder will be…[Read more]

Hi Venera,
First of all, please make sure you are using the newest version.
Second, it would be helpful to check the coherence of the pair that shows this warning. The goal is to check that if the coherence of interferogram is indeed so bad that accurate subpixel coregistration could not be performed.
At last, it would be helpful if you pass…[Read more]

Hello,
I didn’t actually completely overcome this issue yet.
However, the master choice seems to help sometimes. In cases of problematic co-registration I usually try to manually evaluate image list in order to exclude the most noisy ones and choose the most contrast image as a master.
Somebody, correct me if I’m wrong, please. -

I’m still waiting for the sarproz update to processing stripmap data of Sentinel sensor. I’ve been using version 5-may-2017 recently, i’ll be thankfulness if you notice me whenever new sarproz update arrives, which has the capability of processing stripmap sentinel data, and give me new pcodes file.
