Rough mimic of GDAL's RasterAttributeTable in a Zarr file. Main aims are
- Writing RAT columns directly to S3 bucket
- Associating multiple RAT tables with a given raster, to allow grouping of related columns into individual RATs and avoid overly large single attribute tables.
- Concurrent writing of separate columns into the same RAT, allowing computationally intensive columns to be computed in parallel
Module documentation is found here.
Release notes for each version are here
Install from source
pip install .
It requires the zarr package. Use with S3 also requires s3fs & boto3.
