Hi Antonio,

If you restart the software,
you should get a different message, did you try it?
Something else to try:
(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

When sarproz process the coregistration,
the estimated offsets are saved in _coreg_offL and _coreg_offS files in the EXT folder.
These files could be loaded into sarproz (by selecting “choose a real file” from the menu that you can find in most modules)
And you could analyze pixel offsets.
However, at the moment these offsets contain also the…[Read more]

InSAR is by definition relative to a reference point. So, everything is calculated by subtracting the value corresponding to the reference point.
Residual height is the height relative to a reference DEM. Height = external_DEM_height + residual_height.
The deviation of the height estimation depends on many things, as number of images and baselines…[Read more]

You are on the mountains and you are geocoding your data, not orthorectifying it.
You should orthorectify it instead.

1. check that you have a DEM correctly loaded. to check it, you can click “dem visualization” in the frame “preliminary geocoding” in “site processing”. if you get a green flat picture, probably it failed downloading SRTM data (you should have got messages about that). In such a case delete the corresponding SRTM files (SRTM directory in the…[Read more]

Hi Cecilia,
yes, on the manual you find some explanation, here in particular http://sarproz.com/manual/geocod.html
what you have written is correct if no correlation with temperature was estimated. If on the contrary you did remove a temperature-correlated trend, then you have to tick on the corresponding box to see it, otherwise it is removed…[Read more]

please check your email

You can choose any parameter for your reference selection: temporal or spatial coherence, amplitude stability index, reflectivity map or whatever.
Or you can even pick it up manually (ticking the corresponding box) depending on other infos/observations (e.g. you want it on the ground, in a stable area or whatever).
InSAR is a differential…[Read more]

please update your code http://sarproz.com/manual/manage_version.html and try again

can you please send error and log again?
no need to rar them

An alternative link has been included for SRTM data download and a new Sarproz version is currently being uploaded.
Please use the “manage version” module to update your Sarproz version and fix the SRTM data download issue
http://sarproz.com/manual/manage_version.html

your case needs to be checked in person.
if you did not solve it with ur colleagues, we need to find some time to look into it remotely
bests

Please update the code via the “manage version” module, the bug has already been solved

Did you do process the 2 clouds of points?
1- estimation of relative shifts (offsets)
2- estimation of AD pairs
here a brief description
http://sarproz.com/manual/multi_sens.html
After having estimated those 2 things, you can plot vertical and horizontal components either on AD pairs or on a grid (not on the original points)
in the future we will…[Read more]

It looks like thee answer posted here 2 days ago was not uploaded…

You have 2 choices when you find such an error

1) if you have recently uploaded the software, use the “manage version” module to switch back to a previous version
http://sarproz.com/manual/manage_version.html
pick up a locally available version and switch to it pressing the…[Read more]

The reflectivity map is the average amplitude of all images.
The amplitude is measured in volts.
Values there are the output of a normalization.
Usually amplitude is plotted between 0 and 3, you can change the upper value in the advanced parameters http://sarproz.com/manual/adv_param.html
The actual maximum value depends on the strongest scatterer…[Read more]

sorry, this is a bug caused by a recent update. check for updates in the next hour

you need to attach this log E:dam_descendingsite.log
