v0.7.0

What's Changed

Added

• MiniStackPlanner and MiniStackInfo class which does the planning for how a large stack of SLCs will be processed in batches.
  • Previously this was done at run time in sequential.py. We want to separate that out to view the plan in advance/allow us to dispatch the work to multiple machines.
• CompressedSlcInfo class added to track the attributes of a compressed SLC file created during the workflow.
• Added better/more complete metadata to the compressed SLC Geotiff tags, including the phase reference date
• config: phase_linking.max_compressed_slcs to cap the number of compressed SLCs added during large-stack sequential workflows
• interferogram: Add ability to specify manual dates for a Network/VRTInterferogram, which lets us re-interfere the phase-linking results

Changed

• Date functions have been moved from dolphin.utils to dolphin._dates. They are accessible at dolphin.get_dates, etc
• get_dates now uses datetime.datetime instead of datetime.date, so missions like DeltaX won't be impossible to process
• VRTStack has been moved to _readers.py. The minstack planning functions have been removed to focus the class on just reading input GDAL rasters.

Fixed

• When starting with Compressed SLCs in the list of input SLCs, the workflows will now recognize them, find the correct reference date, and form all the correct interferograms

Removed

• Extra subsetting functions from VRTStack have been removed, as they are not used in the workflow and the reimplmenent simple GDAL calls.
• CPURecorder and GPURecorder have been removed to simplify code. May be moved to separate repo.

v0.6.1

What's Changed

• convert dolphin.opera_utils to use external opera_utils in #158

Full Changelog: v0.6.0...v0.6.1

v0.6.0

What's Changed

Added

• opera_utils.get_missing_data_options to parse the full list of SLCs and return possible subsets which have the same dates used for all Burst IDs
• PsWorkflow class for running just the PS estimation workflow
• asv benchmark setup
• @atomic_output decorator for long running write processes, to avoid partially-written output files

Changed

• removed minimum_images as an argument from opera_utils.group_by_burst. Checking for too-few images now must be done by the caller
• opera_utils.group_by_burst now matches the official product name more robustly, but still returns the lowered version of the burst ID.
• Split up config models for easier partial workflow running (e.g. on AWS)
• The s1_disp workflow has been renamed to displacement, since it is not specific to Sentinel-1.
• The configuration was refactored to enable smaller workflow
  • The Workflow config class has been renamed to DisplacementWorkflow.
  • A PsWorkflow config class has been added for the PS estimation workflow.
  • A WorkflowBase encompasses some of the common configuration options.

Maintenance

• ruff has replaced isort/black/flake8 in the pre-commit checks

v0.5.1

What's Changed

• Return ps mask, use scratchdir for tophu unwrapping by @scottstanie in #148

Full Changelog: v0.5.0...v0.5.1

v0.5.0

Bumping minor version due to the number of changes since 0.4.0

Changelog: v0.4.3...v0.5.0

Full Changelog since 0.4.0: v0.4.0...v0.5.0

v0.4.3

Added

• Ability to unwrap using isce3's PHASS
• CorrectionOptions model for specifying the correction options in the Workflow config
  • Currently a placeholder for the files which will be used for tropospheric/ionospheric corrections
• Ability to keep relative files in the Workflow config
  • This is useful for keeping the relative paths to the SLCs in the config, and then running the workflow from a different directory

Changed

• Instead of specifying the unwrapping algorithm in dolphin unwrap as --use-icu, the option is not --unwrap-method
  • This let's us add --unwrap-method "phass", but also future unwrap methods without a --use-<name> for every one
• Use spawn instead of fork for parallel burst multiprocessing
  • This leads to the error Terminating: fork() called from a process already using GNU OpenMP, this is unsafe.
    in certain situations, and does not happen with spawn. See https://pythonspeed.com/articles/python-multiprocessing/ for more details.
    Full Changelog: v0.4.2...v0.4.3

v0.4.2

Added

• use_evd option to force the use of eigenvalue decomposition instead of the EMI phase linking algorithm
• Walkthrough tutorial notebook

Changed

• Moved all OPERA_ variables to a new module dolphin.opera_utils.
  • Other OPERA-specific quirks have been moved to the separate disp-s1 repo,
    but the functions remaining are the ones that seem most broadly useful to sweets
    and other users working with burst SLCs.
  • Changed the burst regex to be able to match COMPASS and the official product name
• Removed WorkflowName for separating stack vs single
  • The name didn't really provide benefit, as the real differences came from other configuration options
• Internals for which functions are called in sequential.py
• Docker image now has tophu installed

Full Changelog: v0.4.1...v0.4.2

v0.4.1

Add back isce3 to avoid optional dependencies

v0.4.0

Split disp-s1 out from dolphin to limit SAS-specific code. This lets us move the core library in dolphin to the isce-framework org.

Requirements

• Added tbb to prevent numba crashes.
• Dropped h5netcdf, pillow
• Made isce3 an optional requirement for unwrapping

Full Changelog: v0.3.2...v0.4.0

v0.3.2

Patch release for the MANIFEST + data files.
