• New processes in proposal state
  • array_append
  • array_concat
  • array_create
  • array_create_labeled
  • array_find_label
  • array_interpolate_linear #173

• Added return value details (property returns) for the schemas with the subtype process-graph. API#350
• apply_neighborhood: Clarify behavior for data cubes returned by the child processes and for that add the exception DataCubePropertiesImmutable.
• Added a guide for implementors that describes numerours implementation details for processes that could not be covered in the specifications itself, for example a recommended implementation for the if process. #246

Changed

• Added proposals folder for experimental processes. Experimental processes are not covered by the CHANGELOG and MAY include breaking changes! #196, #207, PSC#8
  • Moved the experimental process run_udf_externally to the proposals.
  • Moved the rarely used and implemented processes cummax, cummin, cumproduct, cumsum, debug, filter_labels, load_result, load_uploaded_files, resample_cube_temporal to the proposals.
• Exception messages have been aligned always use ` instead of '. Tooling could render it with CommonMark.
• load_collection and mask_polygon: Also support multi polygons instead of just polygons. #237
• run_udf and run_udf_externally: Specify specific (extensible) protocols for UDF URIs.
• resample_cube_spatial and resample_spatial: Aligned with GDAL and added rms and sum options to methods. Also added better descriptions.
• resample_cube_temporal: Process has been simplified and only offers the nearest neighbor method now. The process parameter has been removed, the dimension parameter was made less restrictive, the parameter valid_within was added. #194

Deprecated

• GeometryCollections are discouraged in all relevant processes.

Removed

• Removed the experimental processes aggregate_spatial_binary and reduce_dimension_binary. #258

Fixed

• Clarify that the user workspace is server-side. #225
• Clarify that the condition parameter for array_filter works also on indices and labels.
• Clarify contradicting statements in filter_temporal for the default value of the dimension parameter. By default all temporal dimensions are affected by the process. #203
• Clarify how the parameters passed to the overlap resolver correspond to the data cubes. #184
• Improve and clarify specifications for is_nan, is_nodata, is_valid. #189
• Improve and clarify specifications for all and any. #189
• array_element: Clarify that ArrayNotLabeled exception is thrown when parameter label is specified and the given array is not labeled.
• array_apply, array_element, array_filter: Added the minimum: 0 constraint to all schemas describing zero-based indices (parameter index).
• array_labels: Clarified the accepted data type for array elements passed to the parameter data.
• merge_cubes: Clarified the dimension label order after the merge. #212
• merge_cubes: Clarified the fourth example. #266
• Fixed typos, grammar issues and other spelling-related issues in many of the processes.
• Fixed the examples array_contains_nodata and array_find_nodata.
• Fixed links to openEO glossary and added links to data cube introduction. #216
• Fixed description of apply_dimension with regards to reference systems. Made description easier to understand, too. #234
• Clarified disallowed characters in subtype file-path.
• Clarified that UDF source code must contain a newline/line-break (affects run_udf).
• aggregate_spatial, aggregate_spatial_binary: Clarified that Features, Geometries and GeometryCollections are a single entity in computations. Only FeatureCollections are multiple entities. #252
• aggregate_spatial: Clarified that the values have no predefined order and reducers such as first and last return unpredictable results. #260
• load_collection, parameter spatial_extent: Clarified that all pixels that are inside the bounding box of the given polygons but do not intersect with any polygon have to be set to no-data (null). #256
• load_collection: Clarified that the parameters are recommended to be used in favor of filter_* processes.
• aggregate_temporal and aggregate_temporal_period: Clarified that reducers are also executed for intervals/periods with no data. #263
• dimension_labels: Clarified that the process fails with a DimensionNotAvailable exception, if a dimension with the specified name does not exist.

• The JSON Schema keyword format has been replaced with the custom keyword subtype.
• Schema format/subtype callback has been renamed to process-graph.
• Default values are now specified on the parameter-level, not in the JSON schemas.

• Callback parameters have a new, more advanced schema, allowing to define more aspects of the callback parameters. API#239
• Processes supporting multiple data types in parameters or return values with anyOf are now listing the data types directly as array. anyOf is discouraged.
• Comparison processes eq, gt, gte, lt, lte, neq and between accept all data types as input for the operands.
• add_dimension: Parameter value renamed to label.
• aggregate_polygon, aggregate_temporal, apply_dimension, array_element and resample_cube_temporal: Support labeled arrays. API#245
• aggregate_polygon: The data cube implicitly gets restricted to the bounds of the polygons as if filter_polygon would have been used beforehand. #101

  • Doesn't pass through null, but instead null leads to rejecting the condition.

• ndvi and normalized_difference: Rewrite of the processes with a completely new behavior. #60
• not: Parameter expression renamed to x.
• resample_spatial: Default value of parameter align changed from lower-left to upper-left. #61
• The following operations work on two values instead on a sequence of values: and, divide, multiply, or, subtract, xor. #85
• product works as before, but is not an alias of multiply any longer. #85
• text_begins, text_contains, text_ends: null values are supported and get passed through.
• trim: Renamed to trim_cube.

Deprecated

• filter_bbox, load_collection, resample_spatial: PROJ definitions are deprecated in favor of EPSG codes and WKT2. #58
