Apr 1, 2025April 2025 monthly summary for opendatacube/datacube-core focused on delivering GridSpec enhancements to improve geospatial tiling interoperability and input handling, with a clear path toward odc-geo compatibility. Key outcomes include an opt-in GridSpec pathway that supports a new tile_shape parameter alongside tile_size and resolution, along with improved handling of input formats (resolution/origin) and updates to CSV/tab outputs to reflect the new tile_shape. This work is complemented by new tests and a What's New entry to communicate the enhancement to users and downstream processes, setting the stage for broader library interoperability with odc-geo. The changes enhance tiling accuracy, reduce downstream integration friction, and improve overall maintainability and test coverage for GridSpec-related features.
