Description of the problem

It seems that when defining the meta, there is no 'UTM_ZONE'

This metadata has been introduced for a while now for hyp3. I recommend deleting all existing *.rsc files next to your tif files and running mintpy again.

If the error still persists, could you run the printout prep_hyp3.py command and fill out the detailed template content, so that I may be able to reproduce your error using the Ridgecrest example dataset?

[saeid-aminjafari]

If you are using OpenSARLab Jupyter notebook to prepare your Hyp3 stacks for Mintpy, you should remove the line below from the processing cell that crops the scene:

gdal.Warp(str(clip), str(clip), dstSRS='EPSG:4326', dstNodata=0)

[yunjunz]

This problem is reproduced by a student in the EarthScope 2023 course. The solution from @saeid-aminjafari above works.

That line with gdal.Warp is making the conversion to lat/lon, correct?
So, the new Mintpy version is not accepting hyp3 files in lat/lon?
I have the same error and I converted the files to lat/lon.

[binayak528]

using this when the whole process ends and we are trying to convert it to shapefile using save_qgis the output shapefile has no projected co-ordinates. How can we short this out. we have used the following function after downloading to local system

save_qgis.py /path/timeseries_demErr.h5 -g path/geometryGeo.h5 -o ts.shp

Or any other way that we can get the full timeseries shape file that a single point containing the displacement of all the dates please guide

@saeid-aminjafari do you have any idea for the same problem in mintpy processing using Jupiter notebook? @yunjunz I am using gamma interferograms from ASF. I didn't see any .rsc files in that.
