zarr-developers / geozarr-spec

This document aims to provides a geospatial extension to the Zarr specification. Zarr specifies a protocol and format used for storing Zarr arrays, while the present extension defines conventions and recommendations for storing multidimensional georeferenced grid of geospatial observations (including rasters).

Relationship to GDAL multidimensional data model #27

Closed ashiklom closed 10 months ago

ashiklom commented 1 year ago

As of GDAL 3.1, GDAL has a multidimensional raster data model and API, albeit with what seems like a severely restricted feature set compared to most of GDAL. It apparently works well enough that it's been recommended as a way for users of the R stars library to read Zarr data (https://www.r-bloggers.com/2022/09/reading-zarr-files-with-r-package-stars/).

We should strive for compatibility with this in our implementation, and work with GDAL developers on any issues we identify.

Thanks you for reporting. Facilitating third-party library support is indeed a major point.
