periz replied to the topic APS processing in the forum Sarproz Forum 3 years, 2 months ago
the result is not bad, actually, it’s pretty ok
do not look at the value of the coherence in the temporal plot, that plot is useful only to look at the trend in time, to check whether there are some left signals that were not well modeled
more suggestions:
* u can take a lower threshold for the amplitude stability index, like e.g. 0.7. in this way…[Read more] -
periz replied to the topic Exporting time series for a subset area only in the forum Sarproz Forum 3 years, 3 months ago
In the time series module you can do mainly 2 things:
1. creating a new time series object, based on whatever set of points you want. For doing that (a) you need the data of the whole project to generate new time series and (b) you need to load the set of points using “load mask”. There you are free to create your custom point selection
2. loading…[Read more] -

periz replied to the topic in the forum Big dataset processing 3 years, 5 months ago
no.
ASI and reflectivity maps are calculated using the set of images of your dataset, independently from the images graph (which is something related to operations involving pairs of images)
this means, if you change the set of images, you have to reprocess ASI and REFL maps -
periz replied to the topic in the forum Big dataset processing 3 years, 5 months ago
if you select your points based e.g. on the amplitude stability index == ASI > 0.75 and you get the same amount of points in subsets A, B and C, the explanation is only one: ASI is the same in the 3 datasets.
Instead, for each subset you have to re-process the ASI so that you will get 3 quantities: ASI_A, ASI_B and ASI_C

periz replied to the topic Incidence angle – SARPROZ compiled version in the forum Sarproz Forum 3 years, 5 months ago
Hi,
at the moment we do not have an option to generate a matrix of incidence angle values for all pixels, accessible from the compiled version. You can get it only using the pcodes, because it’s a low-level function. However, do you really need this value for all pixels? if you are not analyzing a huge area, probably an average value is enough. To…[Read more] -
periz replied to the topic Temporary PSI in the forum Sarproz Forum 3 years, 5 months ago
Hi,
here you can see how to process and check amplitude time series (part III): https://www.sarproz.com/utp-course-2012/
To use the result of the amplitude time series processing in the phase time series analysis, you just need to use the amplitude model as weight.
For a more complete discussion and explanation, the best way would be taking a…[Read more] -

Hi,
generally speaking, read carefully this: https://sarproz.com/manual/Sarproz_errors_management.html
In your case, given this message: “get_master_pts: previous files available. Exiting. ”
start over the whole process again (don’t update the site, re-extract the master image)

periz replied to the topic sentinel 1, problems with geocoding timeseries in the forum Sarproz Forum 3 years, 6 months ago
hi,
here some answers to your points
1) if you use the non-parametric approach (e.g. smart=5), the software does not estimate a linear trend. what you can export instead is the cumulative displacement
2) sorry, don’t understand your question
3) ‘External DEM and synthetic amplitude in SAR coordinates’ is a function to generate those products. you…[Read more] -

Hi,
1. you have an old software version, if you want you can get a more recent one with the manage version module
2. in some cases that might still be under investigation sentinel interferograms can be affected by phase jumps along the range direction between two adjacent bursts in azimuth. the message you got warns you of such a possible case

just import a text files with a column of values of temperature in Celsius degrees, one value for each image. Ideally, the temperature should be measured at the satellite acquisition time

the license for windows is different from the one for linux/mac
did you do this?:
1) open a terminal (2) type ‘hostname’ (3) ping the returned name (eg: ping mycomputername)
(4) if no packets are received, add the name returned by ‘hostname’ to the file /etc/hosts - Load More
