v0.19.0

Added

• filtering module for filtering out long wavelength signals from the unwrapped phase
• baseline module for computing the perpendicular baseline. Initial version has logic for OPERA CSLCs, uses isce3
• Interface only for 3D unwrapping
• Faster correlated noise simulation, along with 3d stack simulation with synthetic deformation
• Added ability to read rasters on S3 using VRTStack object
• Eigenvalue solver speedups of 3-9x
• Initial version of 3D unwrapping using spurt

Removed

• the KL-divergence SHP estimator has been removed. GLRT is recommended instead.

Fixed

• reproject_bounds uses the rasterio version, which densifies points along edges for a more accurate bounding box
• The output SHP rasters now output 0 if there was no valid input data
• Logic for filling PS pixels, with and without setting the amplitudes to be the original SLC amplitudes
• ReferencePointError during the displacement workflow now will fall back look only at the condition_file (i.e. choose the point with highest temporal coherence by default)

Changed

• The configuration options for unwrapping have been refactored. Options unique to each unwrapper are grouped into subclasses.
  • Note that older dolphin_config.yaml files will error after this refactor.
• Unweighted time series inversion will make one batch call, providing a large speedup over the vmap version for weighted least squares
• Default for strided PS-picking is to use lowest amplitude dispersion, instead of averaging PS pixels in the multilook window
