Version 1.3.1

Cut a new release for the 2021 UNAVCO short course.

New Features:

• big-data friendly features:
  • memory-efficient tsview.py via downsampling.
  • CPU-efficient dask parallelization in ifgram_inversion.py and dem_error.py by limiting *NUM_THREADS env variable to 1.
• support hyp3 product from ASF HyP3 service [preliminary]
  • load HyP3 products via prep_hyp3.py contributed by Forrest Williams, Bryan Marfito and Jiang Zhu.
  • support UTM projection in tropo_pyaps3.py and solid_earth_tides.py contributed by Jiang Zhu and Bryan Marfito.
• support gmtsar geocoded product via prep_gmtsar.py with contributions from Xiaohua Xu and Rebecca Bussard
• add save_kite.py to save mintpy displacement for pyrocko suite contributed by Marin Govorcin
• timeseries2velocity.py:
  • add two time functions: exponential via --exp and logarithmic via --log contributed by Yuan-Kai Liu
  • support STD propagation from time-series to time func
• modify_network.py:
  • add "Effective Coherence Ratio" method from Kang et al. (2021) contributed by Forrest Williams
  • calc MST network from remaining pairs after all the other criteria applied contributed by Brett Buzzanga
• utilities contributed by Forrest Williams:
  • spatial_filter.py: add double_difference algorithm from Bekaert et al. (2020)
  • generate_mask.py: add --minpixel option to select pixels based on cluster size
  • generate_mask.py: add --vstd option to select pixels based on signal-to-noise ratio using velocity STD
• visualizations:
  • save_kmz: support radar-coded file with point styles
  • tsview.py: plot & save the time function fitting results with contributions from Yuan-Kai Liu
  • view.py:
    • support --ref-point out of the subset box
    • support --ref-lalo for radar-coded file
    • support UTM projections
    • add --math option for simple operations, e.g. sqrt to display STD from VAR file
    • improved save & re-use GPS LOS data in CSV file
    • plot colorbar with the unit in the label for each subplot in case of multi-subplots with different units
    • add --mask-vmin/vmax options to adjust masking thresholds on the fly
  • more colormaps

Technical Improvements:

• translate plot_smallbaselineApp.sh from shell script to python, for better cross-platform compatibility with parallelization, contributed by Panji Brotoisworo and Joshua Zahner
• improvement API support of isce-2/topsApp geocoded products contributed by Yuan-Kai Liu
• improved support of isce-2 data files in the utility scripts (geocode.py, multilook.py and subset.py).
• Circle CI:
  • speedup installation using mamba
  • separate datasets into different runs for better navigation
  • platform-independent fortran compiler
• Various bugs and typo fixes.
