  • Allow take_looks to work with MaskedArrays without converting to np.ndarray

Dependencies

0.12.0 - 2024-02-01

Added

  • Added DatasetWriter protocol
  • Added RasterWriter and BackgroundRasterWriter implementations of this protocol
  • Refactored phase linking
    • Covariance and EVD/MLE use jax
    • This combines the implementation of CPU/GPU, and removes the need for usign pymp

  • Renamed io.Writer to io.GdalWriter to distinguish from RasterWriter
  • Removed the n_workers option from the configuration.
    • There is no more need to have two levels of parallelism (threads_per_worker and n_workers)

  • numpy=>1.23 (bump to minimum version that they're still supporting)
  • scipy>=1.9 (same reason)
  • numba>=0.54

    • Included in DisplacementWorkflow if TEC files are provided

0.10.0 - 2024-01-22

Fixed

  • stitching.merge_images will now give consistent sizes for provided bounds when strides is given

0.9.0 - 2024-01-10

Added

  • DatasetReader and StackReader protocols for reading in data from different sources
    • DatasetReader is for reading in a single dataset, like one raster image.
    • StackReader is for reading in a stack of datasets, like a stack of SLCs.
    • Implementations of these have been done for flat binary files (BinaryReader), HDF5 files (HDF5Reader), and GDAL rasters (RasterReader).

Changed

  • The VRTStack no longer has an .iter_blocks method
    • This has been replaced with creating an EagerLoader directly and passing it to the reader argument

Dependencies

  • Added rasterio>=1.3

0.8.0 - 2024-01-05

Added

  • Ability to unwrap interferograms with the snaphu-py (not a required dependency)
  • Added ability to make annual ifgs in Network
  • Start of tropospheric corection support in dolphin.atmosphere using PyAPS and Raider packages
  • Expose the unwrap skipping with dolphin config --no-unwrap

Changed

  • The output directory for interferograms is now just "interferograms/" instead of "interferograms/stiched"
    • Even when stitching, the burst-wise interferograms would be in the named phase-linking subfolders.
  • Split apart the dolphin.workflows.stitch_and_unwrap module into stitching_bursts and unwrapping
  • Switched output filename from tcorr to temporal_coherence for the temporal coherence of phase linking.
    • Also added the date span to the temporal_coherence output name
  • The default extension for conncomps is now .tif. Use geotiffs instead of ENVI format for connected components.
  • Using ruff instead of pydocstyle due to archived repo

0.7.0 - 2023-11-29

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.
    • This has the reference_date as an attribute, which allows us to know what the base phase is even without starting from the first SLC in the stack (i.e. if we have limited the number of compressed SLCs)
  • Added better/more complete metadata to the compressed SLC Geotiff tags, including the phase reference date
    • Before we were relying on the filename convention, which was not enough information
  • 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.
    • This is to allow for more flexibility in the date parsing, and to allow for the use of datetime.date or datetime.datetime in the output filenames.
  • 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.

0.6.1 - 2023-11-13

Removed

  • dolphin.opera_utils now lives in the separate package

Dependencies

  • Added opera_utils

0.6.0 - 2023-11-07

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 to measure runtime across versions
  • @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.
  • 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

0.4.3 - 2023-10-06

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

0.4.2 - 2023-10-03

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 cam from other configuration options
  • Internals for which functions are called in sequential.py
  • Docker image now has tophu installed

0.4.1 - 2023-09-08

  • Split apart OPERA-specific needs from more general library/workflow functionality
  • Removed the final NetCDF product creation
    • Many rasters in the scratch/ folder are of general interest after running the workflow
    • Changed folder structure so that there's not longer a top-level scratch/ and output/ by default
  • Changed the required dependencies so the isce3 unwrapper is optional, as people may wish to implement their own custom parallel unwrapping

Dependencies

Dropped:

  • h5netcdf
  • pillow

Now optional:

  • isce3 (for unwrapping)

0.3.0 - 2023-08-23

Added

  • Save a multilooked version of the PS mask for output inspection

Changed

  • Pydantic models were upgraded to V2
  • Refactored the blockwise IO into _blocks.py.
    • The iteration now happens over the output grid for easier dilating/padding when using strides
    • New classes with BlockIndices and BlockManager for easier mangement of the different slices

Dependencies

  • pydantic >= 2.1

0.2.0 - 2023-07-25

Added

  • For OPERA CSLC inputs, we now read the nodata polygon and skip loading regions of the SLC stack which are all nodata.
    • This led to a reduction of 30-50% in wrapped phase estimation runtime for each burst stack.
  • Sample test data for the dolphin package loaded onto Zenodo.
  • Adds 3 methods of computing a variable statistically homogeneous pixel (SHP) window when estimating the covariance matrix:
    • Kolmogorov-Smirnov test (KS-test)
    • Generalized likelihood ratio test (GLRT)
    • Kullback-Leibler divergence/distance test (KLD)
    • "rect" is also an option for skipping any statistical test and using the full rectangular multilook window
  • Also included a script to view the window in an interactive matplotlib figure (matplotlib must be installed separately)
  • Added a simple method to check for adjacent-pixel unwrapping errors in unwrap.compute_phase_diffs
  • Adds a method utils.get_cpu_count which returns either os.cpu_count, or (if running in a Docker container) the number of CPUs allocated by Docker
  • If processing stacks from separate bursts, added option n_parallel_bursts to Workflow to run in parallel processes.
  • Created a script to test the incremental/near-real-time version of phase linking
  • Added a new CLI command dolphin unwrap to unwrap a single interferogram/a directory of interferograms in parallel.
  • Added ability to specify a glob pattern for input CSLC files in the YAML config
  • Saves a multilooked PS mask for the default workflow output
  • Allows the user to specify a desired bounds for the final stitched result

Changes

  • Default OPERA dataset is now within /data, reflecting the new COMPASS product spec since CalVal
  • Passing an existing file to VRTStack will no longer error unless fail_on_overwrite=True. The default just prints out the overwrite is happening. This prevents multiple runs in the same folder from errorings just for creating a reference to the SLC files.
  • The environment variable NUMBA_NUM_THREADS is set using the passed in config to prevent numba from using all CPUs during prange calls
  • The sequential.py module uses a different implementation of the sequential estimator to avoid the need for a datum adjustment.
  • The scratch directory holding unwrapped interferograms is named unwrapped instead of unwrap
  • Stitching files now can accept downsampled versions and product the correct geo metadata

Fixed

  • Calculating the nodata mask using the correct input geotransform
  • Trims the overlapped region of the phase linking step when iterating in blocks

Dependencies

  • shapely >= 1.8
  • Numba now supports Python 3.11, so we can drop the Python<3.11 version restriction.

Added testing requirements:

  • pooch
  • pillow>=7.0

0.1.0 - 2023-03-31

  • First version of the _product.py module to output the combined NetCDF product file.
  • _pge_runconfig.py module to handle the separate PGE-compatible configuration, which translates to-from the Workflow object.
  • docker/build-docker-image.sh script to build the docker image.
  • Release scripts for generating documentation, script for validating output data by @gmgunter .
  • Use of a spatial correlation estimate for unwrapping purposes, rather than temporal coherence.
    • This is much more useful when the stack size is small (high temporal coherence), and snaphu is used for unwrapping.
  • masking.py module for masking the interferogram/combined multiple external masks of varying 1/0 conventions.
  • Ability to use existing amplitude mean/dispersion files for the PS portion of the workflow, skipping the step where we compute it using the SLC stack. Useful for small stack sizes
  • Added a create_only option to write_arr to create an empty file without writing data (e.g. to check the boundary results of stitching)

Changed

  • The YAML output/input functions are moved to a YamlModel class, which is a subclass of pydantic.BaseModel.
    • This allows us to use it in both config.py and _pge_runconfig.py.
  • Refactoring of the Workflow layout to more easily extract the input/output files for the PGE run.

Fixed

  • Compressed SLC outputs were getting corrupted upon writing when using strides > 1.
  • Single-update interferograms where the first SLC input is a compressed SLC was broken (using the wrong size raster).
    • Now the result will simply copy over the phase-linking result, which is already referenced to the first raster.

Dependencies

Added requirements:

  • h5netcdf>=1.1
  • Avoid HDF5 version 1.12.1 until NetCDF loading issue is fixed

0.0.4 - 2023-03-17

Added

  • Arbitrary interferogram index selection in Network class.
  • Parallel CPU eigenvector finding using scipy.linalg.eigh.
  • PS selection for strided outputs using the average PS phase within a window (that contains multiple PS).
  • Comments in the YAML file output by the dolphin config command.

Changed

  • The main workflow has been renamed to s1_disp.py to better reflect the workflow, since it can handle both single and stack workflows.

    • The sequential.py and single.py are where these differences are handled.

  • More uniform naming in io.get_raster_<X> functions.

  • The SLC compression is now done in _compress.py to declutter the mle.py module.

  • Replace tqdm with rich for progress bars.

  • The unwrap.py module now uses isce3 to unwrap the interferogram.

  • Docs are now using the mkdocs material theme.

Removed

  • utils.parse_slc_strings in favor of always using utils.get_dates.

    • Users can pass multiple SLC burst (like COMPASS bursts) per date, and the workflow will process per stack then stitch per date.
  • More features for load_gdal to load in blocks.

Changed

  • A small amount of regularization on the coherence matrix is done before inversion during phase linking to avoid singular matrices.
  • Renamed module to _log.py
  • workflows/wrapped_phase.py absorbed much logic formerly in s1_disp_stack.py.

0.0.2 - 2023-01-24
