Known issues and FAQ

[yumorishita]

Unfortunately, I cannot update this LiCSBAS repository for a reason. All known issues are solved in LiCSBAS2 and it will keep updated. I recommend using LiCSBAS2 if you encounter an issue.

In step13:

The cause of the error is

• The number of interferograms is too small
• Too many unwrapping errors are included

Try

• change p11_unw_thre, p11_coh_thre, and/or p12_loop_thre
• crop the area by step05
• improve unwrapping quality and/or increase unwrapped data if you created them manually

[marchelgamaliel]

thank you sir for your response, can you give me some explanation of the variable p11_unw_thre, p11_coh_thre, and/or p12_loop_thre?

AttributeError: module 'numpy' has no attribute 'bool'.
np.bool was a deprecated alias for the builtin bool. To avoid this error in existing code, use bool by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.bool_ here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations. Did you mean: 'bool_'?

Discussion about parameter tuning for a specific case or interpretation of a specific result is out of the scope of the issues in this repository. Please carefully read the LiCSBAS paper, understand the logic, try changing the parameters, and check the result yourself.

The bug was fixed in LiCSBAS2 (https://github.com/yumorishita/LiCSBAS2/pull/55). Please use LiCSBAS2 or apply the fix in your local LiCSBAS script.

What are vel(1) and vel(2) in LiCSBAS_plot_ts.py?

They correspond to cum*.h5 files indicated by -i and --i2 options. By default vel(1) and vel(2) are velocities of filtered and unfiltered time series, respectively.

Cannot download files or the downloading speed is slow in LiCSBAS01_get_geotiff.py.

It could be because of LiCSAR server maintenance and there is nothing to do from the LiCSBAS side. Please contact COMET. https://comet.nerc.ac.uk/comet-lics-portal/ [email protected] https://x.com/COMET_database

Dear Professor, can LICSBAS process cc and unw data processed by envi

[yumorishita]

Yes, as long as you prepare the files with the correct format for LiCSBAS. https://github.com/yumorishita/LiCSBAS/wiki/file_structure#input-for-step-1-1-or-steps-0-3-to-0-5-output-of-step-0-2

If you are using the COMET version LiCSBAS, I cannot support it. Please report any issues to its repository.
