Let’s make an example:
you have processed your dataset, and you got the following outputs (after APS and sparse points processing):
– Integrated Residuals APS
– height and velocity for each PS
So, you go to sparse point geocoding and the sw opens up the “sparse points processing” window asking you to input the processing options. Then you have…[Read more]

the attachment is what I got, it have so many parameters. the value of 5 columns is zero, you can see it in the attachment. you said : when you check it, the sw will open the sparse point processing window and you have to check the processing options you want to apply on your time series. I often experience such a situation, but I don’t konw what…[Read more]

can you include a picture of the APS processing module, so we see which options you picked up?
tell us also which images graph you are using for the estimate

Hi Shimin

first of all, thanks for the question, I discovered an obsolete piece of code.
DBF is in fact an old option that was supposed to be replaced by simple CSV files.
However, I discovered now that the CSV is produced only if you check the “time series” option.
If you geocode the DBF without checking the “time series” option, a DBF file is…[Read more]

here are some files of the process.
after APS removal the coherence of each interferogram became almost zero except 2 of them.
I think I have done something wrong during the process. but I don’t know where is my mistake.

Hi Farnoosh

Residual Height = Height – External DEM

Removing an external DEM should reduce the unknown height (with “unknown height” I mean the source of the topographic component of the interferometric phase). Removing an external DEM is particularly useful in mountainous areas (the external DEM can decrease significantly the range of the…[Read more]

I have another question. what should I do if the coherences are not good after APS removal? what are DSF and R parameters in APS options box?

for this very moment I suggest you to apply a conversion with some other sw for manipulating geotiff files
in the future we’ll modify our code

As I said, you have 2 options:
a. get SLC data (not RAW)
b. focus them with roi-pac (or gamma)

any other way is possible but currently not supported

In the GCP selection module there is a flag: ‘OVW’ which stays for “overwrite”.
If you do not flag it, it will load the previous “mean kml” map.
Since you are not the first one asking about it, I switched it to checked as default…
You’ll get it in the next version, for the moment just check it manually.

HI DP
I　have tried to export .0_A to SLC using SARSCAPE,which include _slc, sml, hdr
However, SARProz is not able to recognize the SLC format.

any suggestion?
thanks

Thanks, DP

I prefer to display geotiff value that represent elevation value.
It would be handy when we would like to compare INSAR DEM with other DEM source, such as SRTM.

Thank you

YUYU

Question for you and for all geotiff users:
is anybody needing an RGB DEM?
Or can I switch the system to automatically (and always) output geotiff DEM files in “black and white”?
After getting a feedback on this, I just need to change 1 line…
thx
dp

hi Yuyu,

as you can read in the sw specifications, sarproz accept SLC data as inputs, that is, focused data.
Level 1.0 is raw data, and it cannot be imported.
You can either order again your data, asking for level 1.1 (SLC or focused) or use an other software to focus it (as roi-pac)

Hi Milan,

the key question is: in which format is your DEM?
if it’s geotiff, nothing to do (unless you find the way to re-write the geotiff).
The sw reads the fill-in boxes only if you are loading a matrix in gamma-format (read the manual).
In that case, changing the lat-lon coordinates has the wished effect.

To understand the error message you…[Read more]
