1. please read the forum rules about what to include in your post
2. as the message says, ur RAM is too low
3 possible workaround: do not generate jpeg files (to do this check the related option in the advanced parameters)

no

It’s a network problem. Try again later. Or check if your network is behind a firewall or a proxy. You can also try to use a different connection (like from home or through a mobile device)

The cache of the MCR component can be found in a folder similar to the following one

C:Users\AppDataLocalTemp\mcrCache8.3main_…

delete the folder and then try again, it should work.

Spatial ramps can arise from the spatial graph integration. Such operation is weighted with the coherence of the connections. Check the coherence and check the Non-linear parameters used to set the range of reliable coherence values. Choosing carefully those parameter should help the stabilization of the integration. If that does not help, it…[Read more]

Hi Paul,
there is a high number of factors that can cause the difference in the results. One of them is the reference point. Then one should check all options you used for processing. Also the outcome of the APS processing plays an important role on the final result. The topic is too broad to be treated here in a single answer. I suggest you to…[Read more]

Hi Paul,
you are missing the most important things:
1. you have to process the external DEM in SAR coordinates
2. you have to choose the “orthorectified” output, in the extended data export
You also miss to tell us which satellite data you are using.
If it is not Sentinel, probably you need to select a GCP manually.
Also, search in the forum,…[Read more]

Please take the time to read this https://www.sarproz.com/groups/sarproz-group/forum/topic/forum-general-rules/
if you want we understand what you are talking about, paste pictures, logs, messages, all possible information you can find.

By looking at your results again, I notice that the deviation of the estimated height is particularly high: is this Sentinel? If so, the estimated residual height is not very accurate, because the normal baselines are very small. Do not get crazy with the ref point selection.
The suggested ref points are chosen also considering their phase…[Read more]

hi linweicheng,
sorry for the late answer. You are trying to import Alternating Polarization Envisat images. At the moment this particular Envisat Mode is not supported. We will include it in the near future.

first of all,
velocity and residual height are two different parameters belonging to two different physical characteristics, very different from each other and usually not correlated.
then, even if the majority of radar reflections would be higher than the ground level, still, reflections would be at different height values. Unless you are in an…[Read more]

Problems can be solved by doing things step by step from the beginning.

Step 0: read this https://www.sarproz.com/groups/sarproz-group/forum/topic/forum-general-rules/
In particular for what concerns files to include when one encounters errors

best

correct.
if you are using matlab, you can type “fast” at the command prompt, this will load all important variables and file names. the you can use “leggi” to read the data, with Type=1. here the help:
Data=leggi(FileName,S,L)
Data=leggi(FileName,S,L,[Svet,Lvet])
Data=leggi(FileName,S,L,[Sin,Sfin,Lin,Lfin])…[Read more]

sorry, no idea. since it’s the most recent version of Matlab, then the suggestion is to write to Mathworks reporting the error.
to temporarily solve the problem, you can use the Sarproz compiled version. you just need to launch the co-registration in the compiled version, then you can switch back to Matlab for doing the rest. The Sarproz license…[Read more]

Sorry, it seems we overlooked your post…
It sounded a system/permissions problem anyway…
But, never mind, now it works…

does this file C:Program FilesMATLABR2018atoolboximagesimagesprivateresampsep.mexw64 exist?

what is the output of “license(‘test’,’Image_Toolbox’)” at the matlab command prompt?

you need to include a lasterror.mat file

open a terminal (command prompt), cd to the folder where main.exe is, launch the application from the terminal by typing “main.exe” and pressing enter, then tell us what messages you get

this means that the installation of the mcr was not successful
try again
and check if the directory where you installed it is in the system path. if not, add it manually to the system path

Hi Rajabun,
this is indeed a visualization bug. What is visualized is the content of the jpeg images which is written in a 0-255 scale. While we work to fix it, you can circumvent the bug by temporarily change the Max Matrix Size value in the advanced parameters https://sarproz.com/manual/adv_param.html In your case, you should write a value equal…[Read more]
