Thanks,
this was a bug (in the compiled version) and it has just been fixed. At this moment you can download the windows compiled version (using the manage version module).
Are you using windows or linux? -

Hi DP
I have put ALOS-2 image folder into “SLC” folder which is created under SARPROZ.
however, the import of ALOS-2 failed.
The message shows “undefined function ‘alos_2_meta’ for input arguments of type ‘char’.
any suggestion?
Thanks -

Hello Daniele,
After downloading the last version, I have verified that only the selected image is processed for extraction and co-registration (Set Orbits is performed for all the images identified as new, but it does not take long time), so the issue is solved.
Thank you/Grazie mille!
Santiago

Hi Santiago,
did you read this? http://www.sarproz.com/groups/sarproz-group/forum/topic/data-import-update-with-external-data/
did you download the last version, produced after that discussion? let me know if it solves your issue.

Hello Daniele,
I have created a SLC data set and now I want to add a new image. According to the manual, this is possible:
-If a dataset was previously created, you can import new images with the “Update” option. All new SLC data placed in the SLC folder will be imported
-You can also choose to import a single new image by selecting it from the…[Read more] -

hi,
so the answer is to forget auto GCP and always geocode manually?
ok, thank you.Milan

periz replied to the topic Geocoding in the forum Sarproz Forum 9 years, 2 months ago
As explained many times to you in person,
in this forum, in the manual, tutorials and so on,
the best way to geocode a dataset is precisely manually. In fact, it takes very little to geocode a dataset manually in Sarproz.
You can check it in the many examples in the tutorials.
Why?
1. because there are many sensors for which the orbital…[Read more] -

Dear Daniele,
I am afraid I don’t understand how GCP can be properly arranged. I started new project, using default parameters.
I performed following:
1. GCP Selection -> Keep Current Orbits -> Write -> Mean Kml…. result: geocoding was shifted around 500 m
2. Computed External DEM and synth. ampl…. -> back to GCP Selection -> Keep Current…[Read more] -
periz replied to the topic APS processing in the forum Sarproz Forum 9 years, 2 months ago
1) why do you use DS=10 and DL=10?
Leave DL=0.
2) how big is the area, did you check the initial selection of points in the refl map/amp stab map?
18 images is enough for a PS-like analysis, but you have to be very careful because all statistical indexes are affected by the low number of images.
3) why didn’t you keep the Non-Linear weights…[Read more] -

OK, and when I go into the Small area module, load the old data (to have the same points, ref. point etc.), then go through select area and sparse point selection (looks ok) and then into MultiImage InSAR Analysis,
what is the problem here? what should I have done?
Thanks, I.

Thank you, it works if I remove the duplicate items from the file you suggest and also from DATASET_INFO/DataSet.txt

periz replied to the topic PSInSAR Analysis in the forum Sarproz Forum 9 years, 2 months ago
this result looks much more reasonable.
however, I’d suggest you to use the I.R. APS. read old posts on this topic.I do not understand your question about the amplitude time series.
Your example looks ok and it shows that no evident pattern is visible.
For other cases, please read some papers about temporary PSs (or check the ampl time series…[Read more] -
periz replied to the topic APS processing in the forum Sarproz Forum 9 years, 2 months ago
probably you used wrong weights.
which APS options are you using?
Can you grab the APS module screen and show them to us?
Also, how many images are you processing, from which sensor, which images graph? -

hi Ivana,
thanks for your message, indeed, I found a bug, introduced by an update, in a non-tested configuration.
I am going to upload soon the bug fix.
The error occurred while managing the index of images to add.
You noticed that in your case the sw processed again all images (which should not happen).
As a consequence, all images were added…[Read more] -

Hello,
I would like to ask what are the recommended instruction if one is updating the dataset with new images, using the external data (temperatures) at the same time – either the number of scenes, or the number of temperatures must be changed first, and one then gets errors.
And if I made it bad, how to get out of it, as I always get the same…[Read more]

Dear Prof.Daniele
I have tried using another parameter for “Images Graph=Delaunay Graph”.
In APS processing I used DSxDL is 0x0 and matr.Coher.Win is 10×10 also used I.P. (Inverted Parameters) options. Hope you give me suggestion for results.Any other question
After I made scatter plot, I was rather confused about analysis relation of amplitude…[Read more] -

Dear Prof.Daniele
I make APS processing ,the Delaunay connection result looks well,but the PS coherence after Graph Inversion and APS remove is very bad. Can you tell me the reason about the bad PS coherence ? And what can I do for have a good result?
Thank you ! -
periz replied to the topic PSInSAR Analysis in the forum Sarproz Forum 9 years, 3 months ago
Hi Ana.
the selection of points looks not good. so, the graph has few good connections and the result is quite bad.
if you are analyzing a 3×3 sqkm area and you have a GPS station at 8km distance you cannot do much.
