Indeed, you were right. Now that I’m working locally the mask loading works perfectly. Thanks!

Hi, Professor Daniele,
The cumulative displacement value in DBF file of result are relative to the reference point. But I don’t know the cumulative displacement of reference point.So the value isn’t accurate?
How to understand the value of cumulative displacement? Whether I should plus or minus a value to obtain the true displcement value?
Thank you.

On the contrary, I believe the net disk is the major problem.
Can you check the network usage?
Or can you simply try to copy the dataset locally? Note that you do not need the SLC folder. So, I believe the rest of the folders should be quite small. -

Hello,
The file is on a net disk, so I think this should not cause major problems. Windows has more than 500 available gb, and the usage of RAM memory is about 50% when running this command. The parameter from which I’m trying to select the points is the Amplitude Stability Index (Amp. Stab. Index 1-Sigma/Mu). I enclose a screen shot, since in my…[Read more]

there is no evident reason for your problem
the file is 2.2MB, less than 1.5e6 points
loading the file in matlab takes a few seconds
I am wondering whether you could have problems affecting matlab and/or windows installation.
or maybe some problems in reading/writing operations: is the file on a local or external disk?
which kind of disk are you…[Read more] -

I am working with Windows. My dataset is not very big (ca. 3600 samples x 3100 lines). For the mask generations, I used the local maxima option (second one). You can download the Maschera.mat from here

Dear Prof Daniele,
I choose second area to analysis. Based on my result, have you think that it reasonable or no? Please, find attach file below.

the mask file is independent from the number of images
it would be nice to know how big is maschera.mat, and which is the size of your dataset (samples and lines).
by the way, which option did you use for mask generation?
are you working with windows? what’s the size of the RAM? -

Hi Santiago,
Dan will be quite busy these days so let me try to answer your questions.
1. You can try use the external DEM in this case. There is one simple judgement to whether your geocoding went well. After geocoding, geocode your reflectivity map into Google Earth kmz file, and check in Google Earth if it is geocoded well. If it is then you…[Read more]

Hello Daniele,
I’m working with an area where I find it difficult to identify a clear and reliable GCP (it’s a totally uninhabited zone) and there is not no topographic feature which could discriminate easily from its surroundings. It is more or less a flat scene at a very high altitude (more than 4000 meters) , with only one hill or peak. In…[Read more]

Daniele,
I’m sorry, the mask zipped file exceeds the maximum allowed limit

Hello Daniele,
I am having a problem with Sparse Point Selection (both in the APS Processing and/or the Sparse Points Selection section which is in blue) . The process of selection seems to get stucked at the Mask Loading step. In previous opportunities I made tests with smaller datasets, of only 3 images, but now I’am working with a dataset of 9…[Read more]

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).
