OME-Zarr Scientific Visualization Datasets for Tool Development

A collection of scientific visualization datasets converted to a chunked, multi-scale OME-Zarr format and hosted on AWS S3. The project is provided by NumFOCUS under a CC-BY-4.0 license through the AWS Open Data Program. It aims to serve as a web-based resource for the scientific visualization community.

Use Cases

• Testing OME-Zarr reader and writer implementations based on the standardized JSON metadata format.
• Developing visualization algorithms for multi-scale, chunked volumetric data based on the described format.
• Benchmarking performance of cloud-based data access pipelines for scientific imaging based on the AWS S3 hosting.
• Enhancing reproducibility in scientific visualization workflows based on the standardized, hosted datasets.

Strengths

• Data is provided in a standardized, community-driven OME-Zarr specification format.
• Datasets are hosted on AWS S3 for reliable, programmatic access via the AWS Open Data Program.
• The project has a clear, permissive license (CC-BY-4.0) for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
