Ez -Insar first impression

[Pierparide]

i’ve noted that when import a kml file in the Ez-Insar appear a window in which i don’t see any study area and i can not manually select the same. There’s a command to select area?

Hi Pierparide,

At the beginning of processing, you provide a .kml file (polygon format) to generate two other .kml files: “target.kml” and “area.kml”. “target.kml” is the same file provided by the user and stored in the work directory. It is used to keep the extent of the Region of Interest (ROI).

“area.kml” is the extent of the ROI defined by a rectangle polygon. In this case, you can manually modify “area.kml” and "target.get" using a text editor or GIS software (i.e., QGIS, Google Earth, etc.) as EZ-InSAR extracts the geographical coordinates from this file before each processing. If the modified files are not a rectangle, EZ-InSAR should use the maximum and minimum values of longitude/latitude from this file.

After the selection of the .kml file, a map (see image) must be visible.

Why this error when check IPF version?

[Pierparide]

Why this when visualize dem?

The dem tiles are detector but processing progress bar stop at 28.6%

Hi, I saw check IPF error too. So, I just download SLCs from ASF and drop in */slc instead of download via Ez-insar. It's works for me!

Hi,

It seems that you have an issue with the creation of your DEM. At this moment, I can’t understand your problem due to the lack of information.

However, my advice is to download the DEM using the ISCE tool:
1) Open a terminal
2) In your home directory (e.g., /home/[your username]/) create a file named .netrc
cd /home/shami
nano .netrc
————————
machine urs.earthdata.nasa.org
login [your Earthdata login]
password [your Earthdata password]
————————
3) Go to your work directory
4) Delete the dem directory and DEM_files.txt
5) Create a new dem directory (i.e., mkdir dem) and cd dem
6) Run the following command:

dem.py -a stitch -b [your coordinates] -s 1 -c -u http://step.esa.int/auxdata/dem/SRTMGL1

7. In EZ-InSAR, after clicking on Select the DEM, select Localhosted DEM and open the dem directory.

If it does not work, your issue should be with ISCE2 (and potentially GDAL).

The last command is a python script or in terminal? Coordinate format is right?

I can see three problems:

1. EZ-InSAR does not currently run on MacOS, only on Linux. Some parts may work but not the full InSAR processing. This command may work on MacOS because it is a command from ISCE.
2. The coordinates should be South North West East without []. (see https://github.com/isce-framework/isce2/tree/main/contrib/stack/topsStack)
3. Before executing a command and starting MATLAB, please load the correct conda environment via "load_insar" command in your Linux terminal.

I think I fixed this issue: see the new version of isceprocessing.m. You can download the new script.

How download it?

[alexisInSAR]

https://github.com/alexisInSAR/EZ-InSAR/blob/Version_2_0_1_Beta/EZINSAR_BIN/ISCE_functions/isceprocessing.m

[Pierparide]

The dem files now are detected but when put “visualize DEM” the processing in progress bar stop at 28.6%.
In attached pictures

[Pierparide]

I thing that problem is because lack dem.wgs84.vrt.xml ad attached snapshot

[alexisInSAR]

It seems that the error come from the run_download_DEM.sh function. Can you try this command alone?
