This +makes it a natural fit for *datacubes*: climate reanalyses, satellite time +series, and model outputs. + +The `sedonadb-zarr` extension reads [Zarr](https://zarr.dev/) groups — +local or in cloud object storage — directly into that raster type, so a +datacube becomes a table you can query in SQL. + +This page walks through loading a Zarr datacube, inspecting its dimensions, +slicing out a 2-D plane, and handing the result to NumPy. + +## Install + +`sedonadb-zarr` is an extension, distributed separately from the core +SedonaDB package: + +```bash +pip install "apache-sedona[db]" sedonadb-zarr zarr numpy geoarrow-pyarrow Review Comment: yes -- This is an automated message from the Apache Git Service.
