[Version 1.0.1] - 2022-03-29

  • Memory improvement in EOPatch merging procedure.
  • Added support for aws_session_token, contributed by @theirix.
  • Fixed an issue in ImportFromTiffTask.
  • Fixed a packaging issue where some new subpackage extensions didn't work in the version 1.0.0 that was released to PyPI.
  • eo-learn abstract package from now on requires fixed versions of eo-learn subpackages.
  • Applied isort formatting on the entire package.
  • Minor improvements in code and documentation.

[Version 1.0.0] - 2022-02-09

Core Changes

  • EOPatch changes:

    • IO for vectors and meta-info switched from pickle to Geopackage, GeoJSON, and JSON files. Objects saved with pickle can be loaded but the format is deprecated.
    • Now supports the in keyword for checking whether an EOPatch contains a given feature.
    • Major update to EOPatch plotting functionality, which now features a simpler matplotlib back-end. See example notebook for more details.
    • Removed some outdated EOPatch methods such as get_feature, rename_feature, etc.
    • Representation (EOPatch.__repr__ method) skips empty features.

  • EOTask changes:

    • EOTask method _parse_features replaced with get_feature_parser and additional helper methods (parse_feature, parse_renamed_feature, parse_features, parse_renamed_features).
    • Removed EOTask.__mul__ as task concatenation as it was unsound.

  • EONode is a newly introduced object for specifying computational graphs. It replaces raw EOTask objects when building an EOWorkflow.

  • EOWorkflow changes:

    • LinearWorkflow is replaced with linearly_connect_tasks function that prepares nodes for a linear workflow.
    • No longer accepts tuples in execution arguments. In cases where this is required, passing arguments to a task can be done with the new InputTask.
    • EONodes form a tree-like structure of dependencies, hence the end-nodes of a workflow contain all information. An EOWorkflow object can be constructed from end-nodes via from_endnodes method.

  • EOExecutor changes:

    • Added RayExecutor as an extension of EOExecutor for working with the ray library.
    • Execution arguments are now given w.r.t. EONode objects instead of EOTasks.
    • Now always returns results, which by default only contain statistics. Other data (for instance the final EOPatch) can be added to results with the new OutputTask.
    • Additionally, supports a filesystem argument for saving logs and reports.
    • Reports now have the option to only link to logs, greatly reducing size in case of large numbers of EOPatches. Logs files are now also more informative.

  • FeatureParser now supports fewer input formats but handles those better. It now returns lists instead of generators. See documentation for more information.

  • WorkflowResults are re-done. They now contain execution stats of nodes (start and end times) and the outputs of OutputTasks in the workflow.

  • FeatureType method is_time_dependant renamed to is_temporal.

Tasks

  • Added LinearFunctionTask which applies a linear function to features.
  • MorphologicalFilterTask moved from ml_tools to features module.
  • Sampling tasks moved geometry to ml_tools module. Sampling tasks have also been greatly upgraded, with the main being:
    • FractionSamplingTask for sampling random points in a class-balanced way
    • BlockSamplingTask for randomly sampling larger blocks of data (can also be 1 pixel blocks)
    • GridSamplingTask for deterministically sampling according to a grid.
  • Removed feature_extractor module.
  • Removed unused submodules of ml_tools (classifier, postprocessing, ...)
  • To reduce core dependencies some functionalities have been moved to extra modules.
  • Removed deprecated and outdated methods and tasks.

Other

  • Moved many examples to new repository. The rest were updated.
  • Switched to github actions for CI.
  • Code was reformatted with black and is now checked to be compliant with the standard.
  • Abstract base classes are now correctly enforced.
  • Added utility functions for working with S3 and AWS.
  • Various minor changes.

[Version 0.10.1] - 2021-10-27

  • Copying EOPatches no longer forces loading of features if the EOPatch was loaded with lazy_loading=True
  • SentinelHubInputTask now requests bands with correct units and should now work with more data collections. The parameter bands_dtype is now by default set to None, which uses the default units of each band. Note: due to changes the task no longer normalizes the output when bands_dtype=np.uint16 is used.
  • Minor fixes and improvements

[Version 0.10.0] - 2021-09-14

  • EOWorkflow now automatically makes a shallow copy of each EOPatch before passing it to any EOTask in the workflow.

  • Improved functionality of merging EOPatches, particularly of merging time-dependent features.
  • Removed support for Python 3.6 and added official support for Python 3.9.
  • Implemented EOPatch.copy and EOPatch.__delitem__ methods.
  • Added eolearn.io.MeteoblueRasterTask and eolearn.io.MeteoblueVectorTask for obtaining weather data. Joint effort with Meteoblue.
  • VectorToRasterTask now supports rasterization of time-dependant vector features. Contributed by @asylve.
  • Fixes in SentinelHubInputTask. Both SentinelHubInputTask and SentinelHubEvalscriptTask now return EOPatches with timestamps that don't have timezone information anymore.
  • Changed rasterio dependency to rasterio>=1.2.7
  • All but eolearn.core tests ported to pytest framework.
  • Switched from Travis CI to GitHub actions.
  • Minor fixes and improvements.
