Description
An xarray backend implementation for ESA EOPF data products in Zarr format.
After installing this package, user can specify a new xarray backend named `"eopf-zarr"` to open EOPF sample products. The backend has two modes of operation, default analysis mode and the native mode. Both modes allow
* to open EOPF sample products from the local filesystem or from
their original object storage using URLs with both `https` or `s3`
protocols;
* to open entire products as `xarray.DataTree` or `xarray.Dataset`;
* to open a subgroup as `xarray.Dataset`. This works with
local filesystem or `s3`-URLs.
The default analysis mode has the aim to represent the EOPF data products in an analysis-ready and convenient way. It provides the following features:
* Open the deeply nested EOPF products as flat `xarray.Dataset`
objects.
* All bands and quality images resampled to a single, user provided
resolution, hence, spatial dimensions will be just `x` and `y`.
* User-specified resampling by passing interpolation methods for
up-scaling and aggregation methods for downscaling.
* CF-compliant spatial referencing of datasets using a shared grid
mapping variable `spatial_ref`.
* Attach other CF-compliant metadata enhancements such as flag values
and meanings for pixel quality information, such as the Sentinel-2
scene classification (variable `scl`).
The native mode does not modify any contents or data, instead it basically delegates to the built-in `zarr` backend.
